Key-In-Ignition Reminder
If the driver's door is opened when the key is in the
ignition and not turned to the ON position, a chime will
sound to remind you to remove the key.
CAUTION!
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
SENTRY KEY IMMOBILIZER SYSTEM Ð IF
EQUIPPED
The Sentry Key Immobilizer System (SKIS) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Onlykeys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.
The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the SKIS indicator
light will come on for 3 seconds immediately after the
ignition switch is turned on for a bulb check. Afterwards,
if the bulb remains on, this indicates a malfunction in the
electronics. If the bulb begins to flash immediately after
the ignition switch is turned on, this indicates that an
invalid key is being used to start the vehicle. Both of
these conditions will result in the engine being shut
down after 2 seconds of running. Keep in mind that a key
which has not been programmed is also considered an
invalid key even if it is cut to fit the ignition for that
vehicle.

garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTION
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone shows that
the battery charge may be too low to start the engine.
With the engine running, the normal operating range is
between 11 and 15 volts. Prolonged gage readings be-
tween 9-11 (undercharge) or above 15 (overcharge) indi-
cate possible malfunction of the generator, voltage regu-
lator or battery. See your dealer if such signs occur.
2. Turn Signal Indicator Light
The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. When the hazard warning system is activated, both
the indicator lights will flash simultaneously.
3. Tachometer
Indicates the engine speed in revolutions per minute.
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
4. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the multi-function control lever to-
wards the steering wheel to switch the headlights from
high to low beam.
5. Airbag Warning Light
This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If the

7. Oil Pressure Gage
Indicates the engine oil pressure. This gage does
not measure oil level. Pressure varies with engine
speed, temperature, and oil viscosity. Normal oil pressure
will be midway between the lowest and highest limit
marks.
8. Sentry Key Indicator Light Ð If Equipped
Refer to ªSentry Key Immobilizer Systemº in
Section 2 of this manual for more information.
9. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the ªMalfunction Indicator
Lightº may flash to alert of serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
10. Cruise Indicator Light
This indicator lights when the electronic speed
control system is turned ON.
11. Check Gages Warning Light
This light illuminates when the voltmeter, oil
pressure, or temperature gages indicate a reading

18. Seat Belt Indicator Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
During the bulb check, if the driver's seat belt is
unbuckled, a chime will sound. After the bulb check or
when driving, if the driver seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertŸ)9in the Occupant Restraints
section for more information.
19. Anti-Lock Warning Light
The amber ABS warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on during
starting, have the bulb repaired promptly. This light also
illuminates to indicate that the Antilock Brake System
self-check is in process 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. In this
case, the system reverts to standard non-antilock brakes.
Turn the engine off and on again to reset the Antilock
Brake System. If the light remains on, see your autho-
rized dealer. If both the red BRAKE and amber ABS
warning lights are on, see your authorized dealer imme-
diately.
20. Fuel Gage
The pointer shows the level of fuel in the fuel tank when
the ignition key is in the ON position. A small arrow
indicates the side of the vehicle where the filler cap (gas
cap) is located.

21. Low Fuel Warning Light
When the fuel level reaches approximately 1.5 U.S.
Gallons (6L) this light will come on and remain on
until fuel is added. The ªLow Fuel Warning Lightº
may turn on and off again, especially during and after
hard braking, accelerations, or turns. This occurs due to
the shifting of the fuel in the tank.
Your vehicle has a programmable electronic feature that
will sound a chime when the ªLow Fuel Warning Lightº
comes on. See the information on ªOverhead Console Ð
Customer Programmable Featuresº in Section 3 to turn
this feature on.
22. Fog Light Indicator Light
This light shows when the fog lamps are on.23. Brake Warning Light
The red BRAKE warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on
during starting, have the bulb repaired promptly. If the
light stays on longer, it may be an indication that the
parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the

center identifies each component for ease of replacement,
if necessary. ªCartridgeº fuses and relays can be obtained
from your authorized dealer.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
²Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
²Store the removed IOD fuse in the Power Distribution
Center location #11 labeled ªIOD Storage.º
²Or, disconnect the negative cable from the battery.
²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This willinsure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
