ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
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.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your au-
thorized dealer to have your sensor function checked.

WARNING!(Continued)
•The capabilities of a TCS-equipped vehicle must
never be exploited in a reckless or dangerous man-
ner, which could jeopardize the user’s safety or the
safety of others.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem 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.
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 capa-
bilities 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.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) enhances directional
control and stability of the vehicle under various driving
conditions. ESC corrects for over/under steering of the
vehicle by applying the brake of the appropriate wheel to
assist in counteracting the over/under steer condition.
Engine power may also be reduced to help the vehicle
maintain the desired path.
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

detected in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located
in the instrument cluster) starts to flash as soon as the tires
lose traction and the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes when
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.
NOTE:
•The ESC Activation/Malfunction Indicator Light and
the ESC OFF Indicator Light come on momentarily each
time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system will
be ON even if it was turned off previously. •
The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The ESC OFF Indicator Light indicates the Elec-
tronic Stability Control (ESC) is off.
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. The system may reduce engine
power and apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will become active
automatically once an excessively swaying trailer is recog-
nized.
NOTE: TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the trailer
tongue weight recommendations. Refer to “Trailer Tow-
ing” in “Starting And Operating” for further information.
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

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.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30
psi (207 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 27 psi (186 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire pressure is suffi-
ciently low enough to turn on the TPM Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPM Telltale Light
will still be on. In this situation, the TPM Telltale Light will
turn off only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.CAUTION!
• The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership 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.
96 SAFETY

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 under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation 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 under-inflation has not reached the level
to trigger illumination of the TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Base System
This is the TPMS warning indicator located in the
instrument cluster. The 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 regularly and to
maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illuminate
in the instrument cluster, an audible chime will be acti-
vated, and the “Check tire pressure” text message will
display when one or more of the four active road tire
pressures are low. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire on
your vehicle, and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. The system will
automatically update and the Tire Pressure Monitoring
Light will extinguish once the updated tire pressures have
5
SAFETY 97

been received. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and the
“Tire Pressure Monitoring Unavailable” text message will
display. If the ignition key is cycled, this sequence will
repeat providing the system fault still exists. The Tire
Pressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors. NOTE:
Your vehicle is equipped with a regular size spare
wheel.
1. The spare tire has a tire pressure monitoring sensor, but it is not monitored until it is mounted in place of any of
the existing four road tires.
2. If you install the spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon
the next ignition key cycle, a chime will sound and the
Tire Pressure Monitoring Telltale Light will turn ON due
to the low tire condition. Then, after driving the vehicle
for up to 20 minutes above 15 mph (24 km/h), the
system will recognize the new sensor, and turn off the
telltale.
3. If a spare tire not equipped with tire pressure monitor- ing sensor is used, then the Tire Pressure Monitoring
Telltale Light will turn ON, flashing for 75 seconds and
then remaining solid for each subsequent ignition key
cycle.
NOTE: For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off during each tire
substitution.

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 your autho-
rized dealer.
The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated 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
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors •
Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch
is in the AVV/START or MAR/ACC/ON/RUN
position. If the ignition switch is in the STOP/
OFF/LOCK 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 in the MAR/
ACC/ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a malfunc-
tion 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

SAFETY 111

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.
(Continued)
WARNING! (Continued)
•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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver And Passenger Front Air Bag Features
The driver and passenger front air bag system is designed
to inflate based on 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.
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.

SAFETY 113

WARNING!(Continued)
•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
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion 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 sub-
stantial vehicle damage — for example, some pole colli-
sions, 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 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 right 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.
