Yellow Telltale
Light What It Means
Anti-Lock Brake (ABS) Indicator Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the igni-
tion is placed in the ON/RUN position and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the Anti-Lock portion of the
brake system is not functioning and service is required. However, the conventional brake
system will continue to operate normally if the brake warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light does not turn on when the ignition is placed in
the ON/RUN position, have the light inspected by an authorized dealer.

Electronic Stability Control (ESC) Indicator Light — If Equipped
Yellow TelltaleLight What It Means
Electronic Stability Control (ESC) Indicator Light
The “ESC Indicator Light” in the instrument cluster will come on when the ignition switch
is turned to the AVV/START position. If the “ESC Indicator Light” comes on continuously
with the engine running, a malfunction has been detected in the ESC system. If this light
remains on after several ignition cycles, and the vehicle has been driven several miles (kilo-
meters) 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 Off Indicator Light” and the “ESC Indicator Light” come on momentarily
each time the ignition switch is turned to AVV/START.
• Each time the ignition is turned to AVV/START, 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. 5

Electronic Brake Force Distribution (EBD)
This 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 ABS before
the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on
when the ignition switch is turned to the ON position
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 switch is turned to
the ON position, have the light repaired as soon as
possible.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under mostbraking conditions. The system automatically prevents
wheel lock, and enhances vehicle control during brak-
ing.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a
slight clicking sound as well as some related motor
noises.
ABS is activated during braking when the system
detects one or more wheels begins to lock. Road condi-
tions such as ice, snow, gravel, bumps, railroad tracks,
loose debris, or panic stops may increase the likelihood
of ABS activation(s).
You also may experience the following when ABS
activates:
•
The ABS motor noise (it may continue to run for a
short time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
•A slight drop of the brake pedal at the end of the stop.
These are all normal characteristics of ABS.

SAFETY 155

WARNING!
•The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
• The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
• The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing.
(Continued)
WARNING! (Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user ’s safety or
the safety of others.
ABS is designed to function with the OEM tires. Modi-
fication may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn
on when the ignition switch is turned to the ON
position and may stay on for as long as four seconds.
If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake
system will continue to operate normally if the “Brake
System Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the “Anti-Lock Brake
156 SAFETY

Warning Light” does not come on when the ignition
switch is turned to the ON position, have the light
repaired as soon as possible.
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 sens-
ing 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 pres-
sure 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,
(Continued)
WARNING!(Continued)
nor can it increase the traction afforded by prevail-
ing road conditions. BAS cannot prevent collisions,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped ve-
hicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the us-
er’s safety or the safety of others.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from
a complete stop while on an incline. If the driver
releases the brake while stopped on an incline, HSA will
continue to hold the brake pressure for a short period. If
the driver does not apply the throttle before this time
expires, the system will release brake pressure and the
vehicle will roll down the hill as normal.
The following conditions must be met in order for HSA
to activate:
•The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.

SAFETY 157

4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times
within twenty seconds. The “ESC Off Indicator
Light” should turn on and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the
right.
8. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system 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 engine power to provide enhanced
acceleration and stability. A feature of the TCS, Brake Limited Differential (BLD), functions similar to a lim-
ited 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 engine torque
to be applied to the wheel that is not spinning. BLD may
remain enabled even if TCS and ESC are in a reduced
mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s) to assist
in counteracting the oversteer or understeer 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 the intended path, ESC applies the brake of
the appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.6

Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The Belt Alert
feature is active whenever the ignition switch is in
the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch is
first in the START or ON/RUN position, a chime will
signal for a few seconds. If the driver or outboard front
seat passenger (if equipped with outboard front passen-
ger seat BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN position the
Seat Belt Reminder Light will turn on and remain on
until both outboard front seat belts are buckled. The
outboard front passenger seat BeltAlert is not active
when an outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range and the driver or outboard front seat passenger is
unbuckled (if equipped with outboard front passenger
seat BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard front passen-
ger seat is unoccupied). The BeltAlert warning se-
quence starts by blinking the Seat Belt Reminder Light
and sounding an intermittent chime. Once the BeltAlert
warning sequence has completed, the Seat Belt Re-
minder Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may repeat
based on vehicle speed until the driver and occupied
outboard front seat passenger seat belts are buckled.
The driver should instruct all occupants to buckle their
seat belts.
Change Of Status
If the driver or outboard front seat passenger (if
equipped with outboard front passenger seat BeltAlert)
unbuckles their seat belt while the vehicle is traveling,
the BeltAlert warning sequence will begin until the seat
belts are buckled again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other
items are placed on the outboard front passenger seat or

WARNING!(Continued)
•Do not use the Automatic Locking Mode to re-
strain occupants who are wearing the seat belt or
children who are using booster seats. The locked
mode is only used to install rear-facing or
forward-facing child restraints that have a har-
ness for restraining the child.
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 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 wir-
ing associated with the electrical Air Bag System Com-
ponents. Your vehicle may be equipped with the fol-
lowing 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
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
• Seat Belt Buckle Switch
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 START or ACC/ON/RUN
position. If the ignition switch is in the STOP/
OFF/LOCK position or in the ACC position,
the air bag system is not on and the air bags will not
inflate.
174 SAFETY

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 sec-
onds for a self-check when the ignition switch is in the
ACC/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 continu-
ously. 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 mal-
function is detected that could affect the air bag system.
The diagnostics also record the nature of the malfunc-
tion. While the air bag system is designed to be main-
tenance 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 ACC/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 condi-
tion the air bags may not be ready to inflate for your
protection. Have an authorized dealer service the air
bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
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.

Response System perform the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power
or until the hazard light button is pressed. The
hazard lights can be deactivated by pressing the
hazard light button.
• Turn on the interior lights, which remain on as long
as the battery has power or for 15 minutes from the
intervention of the Enhanced Accident Response
System.
• Unlock the power door locks.
• Turn off the Fuel Pump Heater (if equipped).
• Turn off the HVAC Blower Motor.
• Close the HVAC Circulation Door.
Enhanced Accident Response System Reset
Procedure
After the event occurs, when the system is active, a
message regarding fuel cutoff is displayed. Turn the
ignition switch from ignition AVV/START or MAR/
ACC/ON/RUN to ignition STOP/OFF/LOCK. Care-
fully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine com-
partment and fuel tank before resetting the system and
starting the engine.
Depending on the nature of the event the left and right
turn signal lights, located in the instrument panel, may
both be blinking and will continue to blink. In order to
move your vehicle to the side of the road, you must
follow the system reset procedure.
