passenger door, other doors, ignition) after three minutes,
the headlights, park lamps and/or turn signals will flash
for an additional 15 minutes.
NOTE:The Panic Alarm and the vehicle security alarm are
quite different. Please take a moment to activate the Panic
Alarm and the vehicle security alarm to hear the differ-
ences in the horn. In case one should go off in the future,
you will need to know which mode has been activated in
order to deactivate it.
Rearming The System
If something triggers the alarm, and no action is taken to
disarm it, the vehicle security alarm will turn off the horn
after three minutes, turn off all of the visual signals after 15
minutes, and then the vehicle security alarm will rearm
itself.
To Arm The System
The vehicle security alarm will set when you use the
Remote Keyless Entry key fob to lock the doors and swing
gate, or when you use the power door lock switch while
the door is open. After all the doors are locked and closed,
the vehicle security light (located on the instrument cluster)
will flash rapidly for about 16 seconds to signal that the
vehicle security alarm is arming. During this 16-second arming period, opening any door or the swing gate will
cancel the arming. If the vehicle security alarm is success-
fully set, the vehicle security light will flash at a slower rate
to indicate the vehicle security alarm is armed.
To Disarm The System
To disarm the vehicle security alarm, you will need to push
the unlock button on the key fob, or turn the ignition
switch to the ON/RUN position. If something has trig-
gered the vehicle security alarm in your absence, the horn
will sound three times, and the exterior lights blink three
times when you unlock the doors. Check the vehicle for
tampering.
The vehicle security alarm is designed to protect your
vehicle; however, you can create conditions where the
vehicle security alarm will arm unexpectedly. If you remain
in the vehicle and lock the doors with the key fob, once the
vehicle security alarm is armed (after 16 seconds), when
you pull the door handle to exit, the alarm will sound. If
this occurs, push the unlock button on the key fob to
disarm the vehicle security alarm. You may also acciden-
tally disarm the vehicle security alarm by unlocking the
driver’s door with the key and then locking it. The door
will be locked but the vehicle security alarm will not arm.

Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake appli-
cation. If the brake light turns on it may indicate that the parking brake is applied, that the brake
fluid level is low, or that there is a problem with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at the
full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system mal-
function or that a problem with the Brake Booster has been detected by the Anti-Lock Brake Sys-
tem (ABS) / Electronic Stability Control (ESC) system. In this case, the light will remain on until
the condition has been corrected. If the problem is related to the brake booster, the ABS pump
will run when applying the brake, and a brake pedal pulsation may be felt during each stop.

The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level conditions.
The vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately. Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most brak-
ing conditions. The system automatically prevents wheel
lock, and enhances vehicle control during braking.
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 begin to lock. Road conditions 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.
WARNING!
•The ABS contains sophisticated electronic equipment
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 capability. Installation of such equip-
ment 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.

214 SAFETY

WARNING!(Continued)
•The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase brak-
ing 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 hydroplaning.
• 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. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode 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 sys-
tem 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 Warn-
ing Light” does not come on when the ignition is turned to
the ON/RUN mode, have the light repaired as soon as
possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Brake Assist System
(BAS), Hill Start Assist (HSA), Traction Control System
(TCS), Electronic Stability Control (ESC), and Electronic
Roll Mitigation (ERM). These systems work together to
enhance both vehicle stability and control in various driv-
ing conditions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC) and Hill Descent Control (HDC).

SAFETY 215

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 is turned to 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 re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to the ON/RUN mode, 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 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-lockbrake 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.
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

Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs) —
If Equipped
Your vehicle may be equipped with Supplemental Seat-
Mounted Side Air Bags (SABs) that are located in the
outboard side of the front seats. The SABs are marked with
a “SRS AIRBAG” or “AIRBAG” label sewn into the out-
board side of the seats.
The SABs (if equipped with SABs) may help to reduce the
risk of occupant injury during certain side impacts, in
addition to the injury reduction potential provided by the
seat belts and body structure.When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant
and the door. The SAB moves at a very high speed and
with such a high force that it could injure occupants if they
are not seated properly, or if items are positioned in the
area where the SAB inflates. Children are at an even greater
risk of injury from a deploying air bag.

SAFETY 253

WARNING!
Do not use accessory seat covers or place objects
between you and the SABs; the performance could be
adversely affected and/or objects could be pushed into
you, causing serious injury.
SABs (if equipped with SABs) are designed to activate in
certain side impacts. The Occupant Restraint Controller
(ORC) determines whether the deployment of the SAB in a
particular impact event is appropriate, based on the sever-
ity and type of collision. The side impact sensors aid the
ORC in determining the appropriate response to impact
events. The system is calibrated to deploy the SAB on the
impact side of the vehicle during impacts that require SAB
occupant protection. In side impacts, the SABs deploy
independently: a left side impact deploys the left SAB only
and a right side impact deploys the right side SAB only.
Vehicle damage by itself is not a good indicator of whether
or not SABs should have deployed.
The SABs (if equipped with SABs) will not deploy in all
side collisions, including some collisions at certain angles,
or some side collisions that do not impact the area of the
passenger compartment. SABs (if equipped with SABs) are a supplement to the seat
belt restraint system. SABs deploy in less time than it takes
to blink your eyes.
WARNING!
•
Occupants, including children, who are up against or
very close to side air bags can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or
area where the side air bags inflate, even if they are
in an infant or child restraint.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating side air bag. To get the best protection from
the side air bags, occupants must wear their seat belts
properly and sit upright with their backs against the
seats. Children must be properly restrained in a child
restraint or booster seat that is appropriate for the
size of the child.
