- SERV (Service) 4WD Indicator Light

• If the light stays on or comes on during driving, it means that the 4WD system

is not functioning properly and that service is required. We recommend you
drive to the nearest service center and have the vehicle serviced immediately.

- Transmission Temperature Warning Light

• This light indicates that there is excessive transmission fluid temperature that

might occur with severe usage such as trailer towing. If this light turns on, stop
the vehicle and run the engine at idle, with the transmission in NEUTRAL, until
the light turns off. Once the light turns off, you may continue to drive normally.

Fuel Cap/Loose Gas Cap Message

• If a “gas cap” message (shown as gASCAP) appears, tighten the gas cap until

a “clicking” sound is heard.

• Press the odometer reset button to turn the message off.

• If the message continues to appear for more than three days after tightening

the gas cap, see your authorized service center.

Oil Change Indicator

Message

• If an “oil change” message (shown as CHAngE OIL) appears and a single

chime sounds, it is time for your next required oil change.

Resetting The Light After Servicing

• Turn the ignition switch to the ON/RUN position (do not start engine).

• Fully depress the accelerator pedal three times within 10 seconds.

• Turn the ignition switch to the OFF/LOCK position.

IF YOUR ENGINE OVERHEATS

• In any of the following situations, you can reduce the potential for overheating

by taking the appropriate action.

• On the highways — slow down.

• In city traffic — while stopped, shift transmission into NEUTRAL, but do not

increase engine idle speed.

NOTE: There are steps that you can take to slow down an impending overheat
condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the

engine cooling system and turning the A/C off can help remove this heat.

• You can also turn the Temperature Control to maximum heat, the Mode Control

to floor and the Fan Control to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat from the engine cooling
system.

• If the temperature reading does not return to normal, turn the engine off

immediately.

• We recommend that you do not operate the vehicle or engine damage will occur.

Have the vehicle serviced immediately.
