ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Anti-Lock Brake System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD), Electronic Roll
Mitigation (ERM), Electronic Stability Control (ESC), Hill
Start Assist (HSA), and Traction Control System
(TCS).These systems work together to enhance both
vehicle stability and control in various driving conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Ready Alert Braking (RAB), Rain Brake
Support (RBS) and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the ESC and Electric Power Steering
(EPS) modules that provides torque at the steering wheel
for certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain vehicle stability. The only notification the driver receives
that the feature is active, is the torque applied to the
steering wheel.
NOTE:The DST feature is only meant to help the driver realize the
correct course of action through small torques on the
steering wheel, which means the effectiveness of the DST
feature is highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)
The EBD function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip
of the rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering the Anti-Lock Brake
System (ABS) before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, striking objects or other vehicles.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.

23_RUP_OM_EN_USC_t.book Page 188

SAFETY189
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to assist in
counteracting these conditions. Engine power may also be
reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the TCS is active. If the ESC Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:When driving with snow chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to allow
more wheel spin. This can be accomplished by momen
-
tarily pushing the ESC OFF button to enter partial mode
“Partial Off” mode. Once the situation requiring “Partial
Off” mode is overcome, turn ESC back on by momentarily
pushing the ESC OFF button. This may be done while the
vehicle is in motion.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a reckless
or dangerous manner which could jeopardize the
user’s safety or the safety of others.

 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows: Úpage 157.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet conditions.
It will periodically apply a small amount of brake pressure
to remove any water buildup on the front brake rotors. It
functions when the windshield wipers are in LO or HI
speed. When RBS is active, there is no notification to the
driver and no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates when
an emergency braking situation may occur by monitoring
how fast the throttle is released by the driver. The
Electronic Brake Control (EBC) system will prepare the
brake system for a panic stop.
Rear Seat Reminder Alert (RSRA)
RSRA alerts you through a visual and auditory notification
of the possible presence of an object, passenger, or pet in
the rear seats if a rear door was opened up to 10 minutes
before the ignition was placed in the ON/RUN position.
RSRA does not directly detect objects, passengers, or pets
in the rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on the
instrument cluster display and sounds an auditory alert
upon the driver placing the ignition in the OFF position to
exit the vehicle.
To enable or disable RSRA, see
Úpage 157.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
vehicle power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more vehicle torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
the Electronic Stability Control (ESC) are in reduced
modes.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
 HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
 Failure to follow these warnings can result in a colli -
sion or serious personal injury.
WARNING!
 Before exiting a vehicle, always come to a complete
stop, then shift the automatic transmission into
PARK and apply the parking brake.
 Always make sure the keyless ignition node is in the
OFF position, key fob is removed from the vehicle
and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
 Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
WARNING!

Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. Note that TSC cannot
stop all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations
Úpage 147.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
The BSM system uses two radar sensors, located inside
the rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.) that
enter the blind spot zones from the rear/front/side of the
vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear and enters standby mode when the vehicle is
in PARK (P).
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.7 m). The zone
length starts at the outside rearview mirror and extends
approximately 10 ft (3 m) beyond the rear fascia/bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
 The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones. 
The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and
trailer before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in false
detections. The BSM Warning Light may even remain
illuminated the entire time the vehicle is in a forward
gear.
 The Blind Spot Monitoring (BSM) system may experi -
ence dropouts (blinking on and off) of the side mirror
warning indicator lights when a motorcycle or any small
object remains at the side of the vehicle for extended
periods of time (more than a couple of seconds).
The area on the rear fascia/bumper where the radar
sensors are located must remain free of snow, ice, and
dirt/road contamination so that the BSM system can
function properly. Do not block the area of the rear fascia/
bumper where the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.).

Sensor Location

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

23_RUP_OM_EN_USC_t.book Page 192

198SAFETY
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(TPMS Warning Light) illuminates, you must increase the
tire pressure to the recommended cold placard pressure
in order for the TPMS Warning Light to turn off.
The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on the
TPMS Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold placard
pressure value
Úpage 312.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.NOTE:
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
Premium System
The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip -
ment that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on after -
market wheels and may contribute to a poor overall
system performance or sensor damage. Customers
are encouraged to use Original Equipment Manufac -
turer (OEM) wheels to ensure proper TPMS feature
operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
 After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.

23_RUP_OM_EN_USC_t.book Page 198

SAFETY199
The TPMS consists of the following components:
Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash on and
off for 75 seconds and then remain on solid. The system
fault will also sound a chime. In addition, the instrument
cluster will display a "SERVICE TPM SYSTEM" message for
a minimum of five seconds and then display dashes (--) in
place of the pressure value to indicate which sensor is not
being received.
If the ignition is cycled, this sequence will repeat, providing
the system fault still exists. If the system fault no longer
exists, the TPMS Warning Light will no longer flash, and
the “SERVICE TPM SYSTEM” message will no longer
display, and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors
 Installing some form of aftermarket window tinting that
affects radio wave signals
 Lots of snow or ice around the wheels or wheel hous -
ings 
Using tire chains on the vehicle
 Using wheels/tires not equipped with TPMS sensors
Vehicles With Compact Spare — If Equipped

1. The compact spare tire does not have a Tire Pressure Monitoring System sensor. Therefore, the
TPMS will not monitor the pressure in the compact
spare tire.

2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure
warning limit, upon the next ignition cycle, the TPMS
Warning Light will remain on and a chime will sound.
In addition, the graphic in the instrument cluster will
still display a different color pressure value.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning Light will flash
on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster will display a
“SERVICE TPM SYSTEM” message for five seconds
and then display dashes (--) in place of the pressure
value.
4. For each subsequent ignition cycle, a chime will sound, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM
SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact
spare, the TPMS will update automatically. In
addition, the TPMS Warning Light will turn off and the
graphic in the instrument cluster will display a new
pressure value instead of dashes (--), as long as no tire pressure is below the low-pressure warning limit
in any of the four active road tires. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display an "Inflate to XX" message
and a graphic showing the pressure values of each tire
with the low tire pressure values in a different color.

Tire Pressure Monitoring System

200SAFETY
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a different
color in the instrument cluster graphic) to the vehicle’s
recommended cold placard pressure value as shown in
the "Inflate to XX" message. Once the system receives the
updated tire pressures, the system will automatically
update, the pressure values in the graphic display in the
instrument cluster will return to their original color, and
the TPMS Warning Light will turn off. The vehicle may need
to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information.
TPMS DEACTIVATION — IF EQUIPPED
The Tire Pressure Monitoring System (TPMS) can be
deactivated if replacing all four wheel and tire assemblies
(road tires) with wheel and tire assemblies that do not
have TPMS sensors, such as when installing winter wheel
and tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring System (TPMS) sensors. Then,
drive the vehicle for 20 minutes above 15 mph (24 km/h).
The TPMS will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display dashes (--) in place of
the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM” message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes
above 15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
"SERVICE TPM SYSTEM" message will no longer be
displayed as long as no system fault exists.OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
 Seat Belt Systems
 Supplemental Restraint Systems (SRS) Air Bags
 Child Restraints
Some of the safety features described in this section may
be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask an
authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in this
section. It tells you how to use your restraint system properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride
buckled up in the rear seat of a vehicle with a rear
seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in the appropriate child
restraint or belt-positioning booster seat in a rear
seating position
Úpage 219.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the front passenger seat,
move the seat as far back as possible and use the
proper child restraint
Úpage 219.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are using it
properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the front air
bags room to inflate.

8. Do not lean against the door or window. If your vehicle has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between
occupants and the door and occupants could be injured.

9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person, see

23_RUP_OM_EN_USC_t.book Page 200

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this section may
be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask an
authorized dealer.
The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC)
monitors the internal circuits and interconnecting wiring
associated with the electrical Air Bag System
Components. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
 Occupant Restraint Controller (ORC)
 Air Bag Warning Light
 Steering Wheel and Column
 Instrument Panel
 Knee Impact Bolsters
 Driver and Front Passenger Air Bags 
Seat Belt Buckle Switch
 Supplemental Side Air Bags
 Supplemental Knee Air Bags
 Front and Side Impact Sensors
 Seat Belt Pretensioners
 Seat Track Position Sensors
 Occupant Classification System
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic parts
of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the ACC
position, the air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power
or it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the ON/
RUN position. After the self-check, the Air Bag Warning
Light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single chime will
sound to alert you if the light comes on again after initial
startup. The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.

The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.
WARNING!
Do not place the seat belt webbing behind the third row
stow clip when using the seat belt to restrain an
occupant. The seat belt will not be positioned properly
on the occupant and they could be more seriously
injured in an accident as a result.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.

If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately

Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are
a supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering
wheel. The passenger front air bag is mounted in the
instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on the air
bag covers.

Front Air Bag/Knee Bolster Locations

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors (if equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.

Passenger Knee Air Bag
WARNING!
 Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room to
inflate. Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
 Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child
restraint in the rear seat. If the vehicle does not have
a rear seat, do not transport a rear-facing child
restraint in that vehicle.

SAFETY211
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle is equipped with a right front passenger
Occupant Classification System (OCS) that is designed to
provide Passenger Advanced Front Air Bag output
appropriate to the occupant’s seated weight input, as
determined by the OCS.Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front air bags
are not expected to reduce the risk of injury in rear, side,
or rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce
substantial vehicle damage — for example, some pole
collisions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC) detects a
collision requiring the front air bags, it signals the inflator
units. A large quantity of non-toxic gas is generated to
inflate the front air bags.
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate and fold
out of the way as the air bags inflate to their full size. The
front air bags fully inflate in less time than it takes to blink
your eyes. The front air bags then quickly deflate while
helping to restrain the driver and front passenger.
Occupant Classification System (OCS) —
Front Passenger Seat
The Occupant Classification System (OCS) is part of a
Federally regulated safety system for this vehicle. It is
designed to provide Passenger Advanced Front Air Bag
output appropriate to the occupant’s seated weight, as
determined by the OCS.
The Occupant Classification System (OCS) consists of the
following:
Occupant Restraint Controller (ORC)
 Occupant Classification Module (OCM) and Sensor
located in the front passenger seat
 Air Bag Warning Light
Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is
located beneath the passenger seat cushion foam. Any
weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front
passenger’s most probable classification. The OCM
communicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and properly
wearing the seat belt.
WARNING!
 No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
 Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
 Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some colli -
sions, air bags won’t deploy at all. Always wear your
seat belts even though you have air bags.
