the vehicle. The system will shut the engine off in two (2)
seconds if someone uses an invalid key to start the
engine.
NOTE:A key, which has not been programmed, is also
considered an invalid key even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running forlonger than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.
NOTE:
²The Sentry Key Immobilizer System is not compatible
with some after-market remote starting systems. Use
of these systems may result in vehicle starting prob-
lems and loss of security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder-equipped components on the
same key chain willnotcause a key-related (transpon-
der) fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Cell phones, pagers, or other RF electronics
will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.

NOTE:Changes or modifications not expressly ap-
proved by the party responsible for compliance could
void the user's authority to operate the equipment.
If your Keyless Entry Transmitter fails to operate from a
normal distance, check for these two conditions.
1. Weak batteries in transmitter. The expected life of the
batteries is from one to two years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
REMOTE STARTING SYSTEM Ð IF EQUIPPED
This system uses the Remote Keyless Entry (RKE) trans-
mitter to start the engine conveniently from outside the
vehicle while still maintaining security. The system has a
targeted range of 328 ft. (100 m).NOTE:The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.Remote Start Button

Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
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.

remote start mode is exited. Refer to ªRemote Start
Systemº in Section 2 of this manual for information on
remote start operation.
Windshield Washers
To use the washer, pull the Windshield Wiper / Washer
Control lever toward you and hold it for as long as
washer spray is desired.
If you activate the washer while the wiper control is in
the delay range, the wipers will operate in low speed for
two wipe cycles after releasing the lever and then resume
the intermittent interval previously selected.
If you activate the washer while the wiper control is in
the OFF position, the wipers will operate for two wipe
cycles and then turn OFF.
Adding Washer Fluid
NOTE:Refer to the ªEngine Compartmentº diagram in
Section 7 for the location of the washer fluid reservoir.
The fluid reservoir for the windshield washers is located
in the engine compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill the reservoir
with windshield washer solvent (not radiator antifreeze)
and operate the system for a few seconds to flush out the
residual water.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.

CAUTION!
²Turn the rear wiper off when driving through an
automatic car wash. Damage to the rear wiper may
result if the rear wiper control is left in the ON
position.
²In cold weather, always turn off the rear wiper
switch and allow the rear wiper to return to the
park position before turning off the engine. If the
rear wiper switch is left on and the rear wiper
freezes to the window, damage to the rear wiper
motor may occur when the vehicle is restarted.
²Always remove any buildup of snow that prevents
the rear wiper blade from returning to the PARK
position. If the rear wiper control is turned OFF
and the blade cannot return to the PARK position,
damage to the rear wiper motor may occur.
Adding Washer Fluid
The windshield washer and rear window washer share
the same fluid reservoir. The reservoir is located in the
front of the engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush out the
residual water.
Rear Window Defroster Ð If Equipped
The electric Rear Window Defroster Control is
located on the climate control. Press this button to
turn on the rear window defroster and the heated side
mirrors (if equipped). An LED in the button will illumi-
nate when the rear window defroster is ON. The de-
froster turns off automatically after approximately 10
minutes of operation for the first push of the button, and
will turn off after approximately 5 minutes for the second
push of the button.

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 opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. (Refer to
ªTire Inflation Pressuresº under ªTires Ð General
Informationº and to ªTire Pressure Monitor System
(TPMS)º in Section 5 of this manual for more
information).5. Electronic Throttle Control (ETC) Warning Light Ð
If Equipped
This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected, the light will turn on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable
and not need towing, however see your authorized
dealer for service as soon as possible.
If the light is flashing when the engine is running, you
may experience power loss, an elevated/rough idle, and
increased brake pedal effort, and your vehicle may
require towing. Immediate service is required.
The light will turn on when the ignition switch is first
turned ON, and remain on briefly as a bulb check. This is
normal. If the light does not turn on during starting, have
the system checked by an authorized dealer.

6. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will turn on when the key is in the ON position before
engine start. If the light does not turn on when turning
the key from LOCK or ACC to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may turn on the light after engine
start. The vehicle should be serviced if the light stays on
through several of your typical driving cycles. In most
situations, the vehicle will drive normally and it will not
require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalyticconverter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 399 for more
information.)
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
7. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the Multi-Function Control Lever on
the left side of the steering column toward you to switch
to Low beam. (See page 133 for more information.)
