Automatic Headlights — If Equipped
This system automatically turns the headlights on or off
according to ambient light levels. To turn the system on,
turn the end of the multifunction lever to the AUTO
position (third detent). When the system is on, the
Headlight Time Delay feature is also on. This means the
headlights will stay on for up to 90 seconds after you turn
the ignition switch to the LOCK position. To turn the
Automatic System off, turn the end of the multifunction
lever out of the AUTO position.NOTE:The engine must be running before the head-
lights will turn on in the Automatic mode.

Windshield Wiper Operation
Rotate the end of the lever upward to the second detent
past the intermittent settings for low-speed wiper opera-
tion. Rotate the end of the lever upward to the third
detent past the intermittent settings for high-speed wiper
operation.
CAUTION!
In cold weather, always turn off the wiper switch and
allow the wipers to return to the park position before
turning off the engine. If the wiper switch is left on
and the wipers freeze to the windshield, damage to
the wiper motor may occur when the vehicle is
restarted.
Intermittent Wiper System
Use the intermittent wiper when weather conditions
make a single wiping cycle, with a variable pause be-
tween cycles, desirable. Rotate the end of the lever to the
first detent position for one of five intermittent settings.
The delay cycle can be set anywhere between 1 to
18 seconds.

CAUTION!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
mobile phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will degrade the
battery even more quickly. Only use these intermit-
tently and with greater caution.
(Continued)
CAUTION! (Continued)
•After the use of high-power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
alternator to recharge the vehicle’s battery.
• Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or acces-
sory bracket from the plug.

Rear Window Defroster — If Equipped
The rear window defroster button is located on
the bottom right-side of the blower control knob.
Press this button to turn on the rear window defroster.
An indicator in the button will illuminate when the rear
window defroster is on. The rear window defroster
automatically turns off after approximately 10 minutes.
For an additional five minutes of operation, press the
button a second time.
NOTE: To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to the
heating elements. Labels can be peeled off after
soaking with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the
window.
• Keep all objects a safe distance from the window.

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 LightThis 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

7. Seat Belt Reminder LightWhen 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
This indicator shows that the high beam head-
lights are on. Push the multifunction control lever
away from you to switch the headlights to high beam.

13. Air Bag Warning LightThis 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 temperature
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 EquippedThis 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 imme-
diately and call an authorized 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 look under the hood
yourself, see “Maintaining Your Vehicle”. Follow the
warnings under the Cooling System Pressure Cap para-
graph.
