Key-In-Ignition Reminder
If you open the driver’s door and the key is fully inserted
in the ignition switch, a chime will sound to remind you
to remove the key.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIM) 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. Only
keys 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 “Sentry Key/ Security Alarm Indicator Light” (located in the instru-
ment cluster) 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.
If the “Sentry Key/Security Alarm Indicator Light”
comes on during normal vehicle operation (it has been
running for longer than 10 seconds) a fault has been
detected in the electronics and the vehicle should be
serviced as soon as possible.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
•If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.

If the swing gate flip-up window is open or the swing gate
is open, connection to the rear window wiper is interrupted
preventing activation of the rear wiper blade. When the
swing gate flip-up window or the swing gate is closed, the
rear wiper switch or the ignition switch needs to be turned
OFF, and then to ON to restart the rear wiper.
NOTE: The rear swing gate will lock while the rear
wiper is operating. The gate will stay locked until the
wiper is turned off and the gate is unlocked (by key,
lock switch, or key fob).
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
Rear Window Defroster
On the top of the climate control panel is a push
button for rear window defrosting. An amber
indicator in the push button will light when the defroster
is turned on. Push again to turn off the defroster prior to
an automatic time-out.

INSTRUMENT CLUSTER DESCRIPTION
1. Tachometer
Indicates the permissible engine revolutions-per-minute
for each gear range. Before reaching the red area, ease up
on the accelerator to prevent engine damage.
2. Turn Signal Indicator Light The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. A chime will sound if the turn signals are left on
continuously for 2 miles (3 km) until they are deacti-
vated.
3. 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. 4. Speedometer
Indicates vehicle speed.
5. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
UNDERSTANDING YOUR INSTRUMENT PANEL 173

inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale. (See page 268 for more infor-
mation.)
6. 4LO Mode Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the 4 LO four–wheel drive mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. (See page 234 for more infor-
mation.) 7. Fog Light Indicator Light — If Equipped
This light shows when the front fog lights are on.
8. 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.
174 UNDERSTANDING YOUR INSTRUMENT PANEL

When the engine is running, the “Malfunction Indicator
Light” 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. (See page 316 for more
information.)
9. Anti-Lock Warning Light (ABS) — If Equipped This light monitors the Anti-Lock Brake System
(ABS) described elsewhere in this manual. This
light will come on when the ignition switch is turned to
the ON position and may stay on for as long as three
seconds.
If the light comes back on immediately or comes on
during 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 provided that the BRAKE
warning light is not on. Also, a chime will sound if the
light comes back on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefit of Anti-Lock
Brakes.
The operation of the ABS light can be checked by turning
the ignition switch from the OFF position to the ON
position. The light should illuminate for approximately
four seconds. The light should then turn off unless a
brake fault is detected. If the light does not illuminate,
have the light inspected by an authorized dealer.
10. Charging System Warning Light
This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging system

the instrument cluster). For additional information, refer
to “Overhead Console — If Equipped” in Section 3. (See
page 135 for more information.)
NOTE: The warnings “LOCOOL” and “GASCAP” will
always be displayed in the odometer display.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
14. Cruise Indicator Light This indicator lights when the speed control
system is turned ON. 15. Oil Pressure Warning Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch is
turned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on, have the system checked by your autho-
rized dealer.
If the warning light comes on and remains on while
driving, stop the vehicle and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED. Also, a single chime will sound.
16. Transmission Temperature Warning Light This light indicates that there is excessive trans-
mission fluid temperature that might occur with
severe usage such as trailer towing or snow plowing. If
this light comes on, stop the vehicle and run the engine at
idle or faster, with the transmission in N (Neutral) until
the light goes off.
