Raise the windshield and reinstall the side bars as soon as
the task that required their removal is completed and
before you return to on-road driving. Both you and your
passenger should wear seat belts at all times, on-road and
off-road, regardless of whether the windshield is raised
or folded down.
Outside rearview mirrors are mounted on the doors. If you
choose to remove the doors, see your authorized dealer for
a replacement cowl-mounted outside mirror. Federal law
requires outside mirrors on vehicles for on-road use.
WARNING!Carefully follow these warnings to help protect
against personal injury:
• Do not drive your vehicle on-road with the wind-
shield down. (Continued) WARNING! (Continued)• Do not drive your vehicle unless the windshield is
securely fastened, either up or down.
• Eye protection, such as goggles, should be worn at
all times when the windshield is down.
• Be sure that you carefully follow the instructions
for raising the windshield. Make sure that the
folding windshield, windshield wipers, side bars,
and all associated hardware and fasteners are cor-
rectly and tightly assembled before driving your
vehicle. Failure to follow these instructions may
prevent your vehicle from providing you and your
passengers protection in some accidents.
• If you remove the doors, store them outside the
vehicle. In the event of an accident, a loose door
may cause personal injury. 3 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 287

WARNING!You or others could be injured if you carry the side

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position.
2. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN, and remain
on briefly as a bulb check. If the light stays on or comes
on while driving, turn off some of the vehicle’s non-
essential electrical devices or increase engine speed (if at
idle). If the charging system light remains on, it means
that the vehicle is experiencing a problem with the
charging system. Obtain SERVICE IMMEDIATELY. See
an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”. 3. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
4. Low Fuel Warning Light
When the fuel level reaches approximately 2.8 gal
(10.6L) this light will turn on and a single chime
will sound.
5. Speedometer
Indicates vehicle speed.
6. Front Axle Lock Indicator — If Equipped
Indicates when the front axle lock has been
activated.300 UNDERSTANDING YOUR INSTRUMENT PANEL

7. Seat Belt Reminder Light
When the ignition switch is first turned to ON/
RUN, this light will turn on for four to eight
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 Reminder Light
will flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
8. Turn Signal Indicators
The left or right arrow will flash with the corre-
sponding exterior turn signal lights when the turn
signal lever is operated. A chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn signal on.
NOTE: If either indicator flashes at a rapid rate, check
for a defective outside light bulb. 9. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started; if the bulb does not come on, have the system
checked by an authorized dealer. If the light turns on while
driving, stop the vehicle and shut off the engine as soon as
possible. A chime will sound 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.
10. High Beam Indicator

will remain illuminated and a chime will sound. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 301

11. 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) / Electronic Stability Control (ESC) system.
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 necessary.
WARNING!Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. (Continued)302 UNDERSTANDING YOUR INSTRUMENT PANEL

WARNING! (Continued)It will take longer to stop the vehicle. You could have
a collision. 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/RUN position. The light should illuminate for ap-
proximately 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/RUN posi-
tion.
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 Operating”.

13. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
14. Rear Axle Lock Indicator — If Equipped
This light indicates when the rear axle lock has
been activated.
15. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000). CAUTION!Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
16. Coolant Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on while driving, safely pull over
and stop the vehicle. If the A/C system is on, turn it off.
Also, shift the transmission into NEUTRAL and idle the
vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service.
NOTE: As the coolant temperature gauge approaches
 H,  this indicator will illuminate and a single chime will
sound. Further overheating will cause the temperature304 UNDERSTANDING YOUR INSTRUMENT PANEL

gauge to pass  H.  In this case, a continuous chime will
sound, until the engine is allowed to cool or the 4 minutes
duration is expired, whichever come first.
17. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
18. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range. CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to (Continued)

WARNING! (Continued)look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
19. Cruise Indicator
This indicator shows when the electronic speed
control system is turned on.
20. 4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the four-wheel drive mode, and the front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. 21. Odometer/Trip Odometer/ECO (Fuel Saver Indica-
tor) Button
Press this button to change the display from odometer to
either of the two trip odometer settings or the “ECO”
display. Trip A or Trip B will appear when in the trip
odometer mode. Press and hold the button for two
seconds to reset the trip odometer to 0 miles or kilome-
ters. The odometer must be in trip mode to reset.
22. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
23. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended by306 UNDERSTANDING YOUR INSTRUMENT PANEL

TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
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 tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. 24. Odometer / Trip Odometer Display Area
The odometer display shows the total distance the vehicle
has been driven. The trip odometer shows individual trip
mileage. Refer to “Odometer/Trip Odometer/ECO (Fuel
Saver Indicator) Button” for additional information.
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. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.308 UNDERSTANDING YOUR INSTRUMENT PANEL
