VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors
and ignition for unauthorized operation. When the Ve-
hicle Security Alarm is activated, the system provides
both audible and visible signals. For the first three
minutes the horn will sound and the headlights, park
lamps and/or turn signals will flash and Vehicle Security
Light will flash repeatedly. For an additional 15 minutes
only, the headlights, park lamps and/or turn signals and
Vehicle Security Light will flash. The engine will run only
if a valid Sentry Keyis used to start the vehicle. Use of
the Sentry Key will disable the alarm.
Rearming of the System
The Vehicle Security Alarm will rearm itself after the 15
additional minutes of headlights and Vehicle Security
Light flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
To Set the Alarm
The Vehicle Security Alarm will set when you use the
power door locks, or use the Remote Keyless Entry (RKE)
transmitter to lock the doors. After all the doors are
locked and closed, the Vehicle Security Light in the
instrument panel cluster will flash rapidly for about
16 seconds to indicate that the alarm is being set. After
the alarm is set, the Vehicle Security Light will flash at a
slower rate to indicate that the system is armed.
NOTE:If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the system checked
by an authorized dealer.
To Disarm the System
Use the RKE transmitter to unlock the door. If something
has triggered the system in your absence, the horn will
sound three times when you unlock the doors and the
Vehicle Security Light will flash for 30 seconds. Check the
vehicle for tampering.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down or in partially open positions. This is a
normal occurrence and can be minimized. If the buffeting
occurs with the rear windows open, open the front and
rear windows together to minimize the buffeting.
OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems:
•Three-point lap and shoulder belts for the driver and
all passengers
•Advanced Front Airbags for driver and front passen-
ger — if equipped
•An energy-absorbing steering column and steering
wheel
•Knee bolsters/blockers for front seat occupants
•All seat belt systems (except driver’s, first and second
row center position) include Automatic Locking Re-
tractors (ALR)
If you will be carrying children too small for adult-sized
seat belts, the seat belts or the Lower Anchors and Tether
for CHildren (LATCH) feature also can be used to hold
infant and child restraint systems.
NOTE: The Advanced Front Airbags have a multistage
inflator design. This allows the airbag to have different
rates of inflation based on severity and type of collision.
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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 37

20. Cargo LightThe cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
21. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. 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 malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS). 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 capac-
ity 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 condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

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
an accident. Have the vehicle checked immediately.
Vehicles equipped with the 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 position. The light should illuminate for approxi-
mately 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 position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.
22. Oil Pressure Warning Light This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants or wood or cardboard, etc. This could
result in death or serious injury to the driver, occu-
pants or others.
24. Airbag Warning Light This light turns on and remains on for six to
eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information. 25. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
26. Anti-Lock Brake (ABS) Light This light monitors the Anti-lock Brake System
(ABS). The 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 ABS light remains on or turns 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 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 switch is turned to the ON position, have the
light inspected by an authorized dealer.

BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
Dual Rear Wheel Models Only
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
Four-Wheel Anti-Lock Brake System
WARNING!
The Four-Wheel Anti-Lock Brake System contains
sophisticated electronic equipment. It may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting equipment.
This interference can cause possible loss of anti-lock
braking capability. Installation of such equipment
should be performed by qualified professionals.
The Four-Wheel Anti-Lock Brake System (ABS) is de-
signed to aid the driver in maintaining vehicle control
under adverse braking conditions. The system operates
5

with a separate computer to modulate hydraulic pressure
to prevent wheel lockup and help avoid skidding on
slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.
The ABS conducts a low-speed selftest at about 10 mph
(16 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
When you are in a severe braking condition involving
use of the ABS, you will experience some pedal drop as
the vehicle comes to a complete stop. This is the result of
the system reverting to the base brake system and is
normal.Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal, and indicate that the
system is functioning.
ABS Warning Light
The ABS includes an amber warning light. When the light
is illuminated, the ABS is not functioning. The system
reverts to standard, non-anti-lock brakes.
WARNING!
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.

WARNING! (Continued)
•The Anti-Lock Brake System (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 accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
