WARNING!
Leaving unattended children in a vehicle is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal, or the shift lever. Do
not leave the key in the ignition. A child could
operate power windows, other controls, or move the
vehicle.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition,
sounds a signal to remind you to remove the key.NOTE:
The Key-In-Ignition reminder only sounds
when the ignition key is placed in the LOCK or ACC
position.
STEERING WHEEL LOCK
Your vehicle may be equipped with a passive steering
wheel lock. This lock prevents steering the vehicle with-
out the ignition key. If the steering wheel is moved
approximately a half turn in either direction, and the key
is not in the ignition, the steering wheel will lock.
To Manually Lock the Steering Wheel
With the engine running, rotate the steering wheel one–
half revolution from the straight ahead position, turn off
the engine, and remove the key. Rotate the steering wheel
slightly in both directions until the lock engages.
To Release the Steering Wheel Lock
Insert the key in the ignition, and turn the wheel slightly
to the left or right, to disengage the lock.

WARNING! (Continued)
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss of
control of the vehicle.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

System can be reactivated by pushing the Electronic
Speed Control ON/OFF button and resetting the desired
vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster will illuminate. To turn the Elec-
tronic Speed Control system off, push the ON/OFF
button a second time. The cruise indicator light will turn
off. The Electronic Speed Control system should be
turned off when not in use.
WARNING!
Leaving the Electronic Speed Control system on

11. Brake Warning LightThis 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) / Electronic Stability Program (ESP) sys-
tem. 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 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 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.
12. Anti-Lock Brake (ABS) Light After the ignition is turned on, the Anti-Lock
Brake System (ABS) light illuminates to indicate
function check at vehicle start-up. If the light remains on
after start-up or comes on and stays on at road speeds, it
may indicate that the ABS has detected a malfunction or
has become inoperative. The system reverts to standard
non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning
Light are on, see an authorized dealer immediately. Refer
to “Anti-Lock Brake System” in “Starting And Operat-
ing”.

WARNING!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent acci-
dents, including those resulting from excessive speed
in turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user’s safety or the safety of others.
27. O/D (Overdrive) Off Indicator Light This light will illuminate when the O/D OFF
button has been selected and overdrive has been
turned off. The O/D OFF button is located on the center
console. 28. Sway Bar Indicator Light — If Equipped
This indicator will illuminate when the front
sway bar is disconnected.
29. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Warning Light The Electronic Stability Program (ESP) / Brake
Assist System (BAS) warning light in the in-
strument cluster comes on when the ignition
switch is turned to the ON position. The light
should go out with the engine running. If the ESP/BAS
warning light comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at an authorized dealer as
soon as possible. Refer to “Electronic Brake Control
System” in “Starting And Operating” for further infor-
mation.
