INSTRUMENT CLUSTER DESCRIPTION
1. Check GaugesThis light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:
•If the gauge pointer moves to either extreme of the
gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
•The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the engine
control module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
3. Turn Signal Indicators Lights in instrument cluster flash when outside turn
signals are operating.

4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.
CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Warning Light The indicator lights and remains lit for six to
eight seconds when the ignition is first turned
on. If the light stays on, flickers or comes on
while driving, have the airbag system checked
by an authorized dealer.
6. High Beam Indicator This indicator shows that headlights are on high
beam. 7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five 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 Warning Light will flash or
remain on continuously. Refer to \6Enhanced Driver Seat
Belt Reminder System (BeltAlert\3)\6 under “Occupant
Restraints” in section 2.
8. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.

9. Oil Pressure GaugeThe pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
10. Transfer Case Position
This display indicator shows the transfer case position
selection.
For additional information refer to “Four-Wheel Drive
Operation” in Section 5 of this manual. 11 .
TOW HAUL
The TOW HAUL button is located at the end of
the shift lever. This light will illuminate when
the TOW HAUL OD/OFF button is pushed
once.
12. OD/OFF
the OD/OFF button is located at the end of the shift lever.
This light will illuminate when the TOW HAUL OD/OFF
button is pushed twice.
13. Temperature Gauge The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range
indicates that the engine cooling system is operat-
ing satisfactorily.
164 UNDERSTANDING YOUR INSTRUMENT PANEL

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 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 authorized deal-
ership 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-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
14. 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.

button down for a period of six seconds. The odometer
will change to trip value first, then it will display the
engine hour value. The engine hours will be displayed
for a period of 30 seconds until the ignition is turned off
or the engine is started.
Change Oil Message
Your vehicle is equipped with an engine oil change
indicator system. The “Change Oil” message will flash in
the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty cycle based, which
means the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON/RUN
position. To turn off the message temporarily, press and
release the Trip Odometer button on the instrumentcluster. To reset the oil change indicator system (after
performing the scheduled maintenance) refer to the fol-
lowing procedure.
1. Turn the ignition switch to the ON position. (Do not
start the engine.)
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary repeat this procedure.
17. Front Fog Light Indicator — If Equipped This light shows when the front fog lights are ON.

18. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system which monitors
the emissions and engine control system. If the
vehicle is ready for emissions testing the light will come
on when the ignition is first turned on and remain on, as
a bulb check, until the engine is started. If the vehicle is
not ready for emissions testing the light will come on
when the ignition is first turned on and remain on for
15 seconds, then blink for five seconds, and remain on
until the vehicle is started. If the bulb does not come on
during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service. Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
19. 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.
168 UNDERSTANDING YOUR INSTRUMENT PANEL

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 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.
20. Anti-Lock Brake (ABS) Light This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds. If the ABS light remains on or turns on while 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 if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
21. Electronic Throttle Control (ETC)
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. If the light remains
lit with the engine running your vehicle will usually be
drivable, however, see your authorized dealer for service
as soon as possible. If the light is flashing when the
170 UNDERSTANDING YOUR INSTRUMENT PANEL

engine is running, immediate service is required and you
may experience reduced performance, an elevated/
rough idle or engine stall and your vehicle may require
towing. The light will come on when the ignition is first
turned on and remain on for 15 seconds as a bulb check.
If the light does not come on during starting, have the
system checked by an authorized dealer.
22. SERV 4WD IndicatorThe 4WD indicator will be illuminated when-
ever the 4WD mode is engaged for either the
manual or electric shift 4WD systems. The
SERV 4WD indicator monitors the electric shift
4WD system. If the SERV 4WD light stays on or comes on
during driving, it means that the 4WD system is not
functioning properly and that service is required. 23. Transmission Temperature Indicator (Automatic
Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel drive
operation (e.g., snow plowing, off-road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
24. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
25. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.

26. Low Fuel LightThis light illuminates when the pointer is between
“E” and 1/8 indication mark (approximately 15%
of tank volume) on the fuel gauge. When the fuel
gauge pointer is on “E” (equivalent to Distance To Empty
[DTE]=0ontheoverhead console, if so equipped) there
is reserve fuel capacity, which corresponds to approxi-
mately 8% of tank volume. This reserve capacity was put
in place to prevent the likelihood of customers running
out of fuel when operating at maximum load conditions
in areas where there aren’t many fuel stations.
Fuel tank volumes are as follows:
•52 gal (197 L) - Standard Rear Tank
•22 gal (83 L) - Optional Mid Ship Tank
27. CRUISE Indicator This indicator lights when the electronic speed
control system is turned on.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the frequency and/or
time in hours and minutes (depending on your radio
model) whenever the ignition switch is in the ON or ACC
position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
On the RAQ radio the time button alternates the location
of the time and frequency on the display. On the REF only
one of the two, time or frequency, is displayed at a time.
Clock Setting Procedure
1. Press and hold the time button until the hours blink.
2. Adjust the hours by turning the right side Tune/
Audio control.
