REAR activated. LOCK

12. 4WD Indicator Light

This light alerts the driver that the vehicle is in the four-wheel drive mode, and the front and rear driveshafts are mechanically lockedtogether forcing the front and rear wheels to rotate at the same speed.

13. Shift Indicator Light If Equipped

This light shows the driver when to shift to the next higher gear for best fuel economy (4.0L Only).

14.Oil Pressure Gauge

Indicates engine oil pressure. This gauge does not indicate oil level, and pressure varies with engine speed, temperature and oil viscosity. Consistent lower readings indicate possible malfunction. Seek authorized service.


15.Coolant Temperature Gauge

Indicates engine coolant temperature. The red zone to the far right indicates possible overheating. Seek authorized service immediately if the gauge operates in the red zone. In U.S. vehicles, temperature is indicated in degrees fahrenheit; in Canadian vehicles in degrees centigrade.

16. Airbag Warning Light

This indicator lights and remains lit for 6 to 8 seconds when the ignition is first turned on. If the light does not come on for 6 to 8seconds, stays on or comes on while driving,

have the airbag system checked by an authorized


17. Check Gauges Warning Light

This light monitors the engine coolant tem perature, engine oil pressure, and voltage gauges. If it detects an extreme condition achime will sound and the light will come on. If the light comes on, check the operation of these gauges for a malfunction condition.

18. Malfunction Indicator Light

This light is a part of an Onboard Diagnostic System called OBD II that monitors engine, and automatic transmission control systems.The light will illuminate when the ignition is in the ON position before engine start. If the bulb does not come on when turning the key from OFF to ON, have the condition checked promptly.

Certain conditions such as a loose or missing gas cap, poor quality fuel, etc. may illuminate the light after engine start. The vehicle should be serviced if the light stays on through several typical driving styles. In most situations, the vehicle will drive normally and will not require towing.

When the engine is running, the "Malfunction Indicator Light" may flash to alert 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.


19. Trip Odometer Button

Press and release this button to toggle between the odometer and trip odometer displays. This button is also used to reset the trip odometer to 0. While the display is showing the trip odometer, press and hold the button for approximately 2 seconds and the display will reset to 0.

20. Odometer/Trip Odometer

The odometer shows the total distance the vehicle has been driven.

The odometer will "illuminate" when the drivers door has been opened, and will remain on for 20 seconds after exiting the vehicle.

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. Therefore, 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 the correct mileage can be determined.

The trip odometer shows individual mileage up to 999.9 miles (1 600 km). To switch from odometer to trip odometer, press the trip odometer button.

21.Anti-Lock (ABS) Warning Light

After ignition is turned on, illuminates to indi cate function check at vehicle start-up. If 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 red BRAKE warning light and the amber ABS warning light are on, see your dealer immediately. Refer to "Anti-Lock Brake System" in Section 5 of this manual.

22. Brake Warning Light

After ignition is turned on, illuminates to in dicate function check at vehicle start-up. Indicates parking brake is applied. If the light stays on when the parking brake is off, it indicates a possible brake system fluid leak or low pressure level, see your authorized dealer immediately.


If the parking brake is applied and the vehicle is in motion, the red BRAKE warning light will "flash" and a chime will sound.

The 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 approximately 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.

23.Low Fuel Warning Light

When the fuel level reaches approximately 2 U.S. Gallons (7.6L) this light will come on and remain on until fuel is added. The "Low Fuel Warning Light" may turn on and off again, especially during and after hard braking, accelerations, or turns. This occurs due to the shifting of the fuel in the tank.

24. Fuel Cap Indicator

This symbol indicates the side of the vehicle where the fuel cap is located.

25. Fuel Gauge

The pointer shows the level of fuel in the fuel tank. When the fuel gauge pointer initially moves to E, for your safety, approximately 2 U.S. Gallons (7.6L) of fuel remain.

NOTE: When the ignition switch is turned to OFF, the fuel gauge, voltmeter, oil pressure and temperature gauges may not show accurate readings. When the engine is not running, turn the ignition switch to ON to obtain accurate readings.


The clock and radio each use the display panel built into the radio. A digital readout shows the time in hours and minutes whenever the ignition switch is in the ON or ACC position and the time button is pressed.

When the ignition switch is in the OFF position, or when the radio frequency is being displayed, time keeping is accurately maintained.


Clock Setting Procedure

  1. Turn the ignition switch to the ON or ACC position
    and press the time button. Using the tip of a ballpoint pen
    or similar object, press either the hour (H) or minute (M)
    buttons on the radio.

  2. Press the H button to set hours or the M button to set
    minutes. The time setting will increase each time you
    press a button.


Radio Broadcast Signals

Your new radio will provide excellent reception under most operating conditions. Like any system, however, car radios have performance limitations, due to mobile operation and natural phenomena, which might lead you to believe your sound system is malfunctioning. To help you understand and save you concern about these "apparent" malfunctions, you must understand a point or two about the transmission and reception of radio signals.

Two Types of Signals

There are two basic types of radio signals... AM or Amplitude Modulation, in which the transmitted sound causes the amplitude, or height, of the radio waves to vary... and FM or Frequency Modulation, in which the frequency of the wave is varied to carry the sound.

Electrical Disturbances

Radio waves may pick up electrical disturbances during transmission. They mainly affect the wave amplitude, and thus remain a part of the AM reception. They interfere very little with the frequency variations that carry the FM signal.

AM Reception

AM sound is based on wave amplitude, so AM reception can be disrupted by such things as lightning, power lines and neon signs.

FM Reception

Because FM transmission is based on frequency variations, interference that consists of amplitude variations can be filtered out, leaving the reception relatively clear, which is the major feature of FM radio.



Radio Security Code

This radio is equipped with an anti-theft feature which requires that a four digit code number be entered whenever the power supply is interrupted (such as a disconnected battery). The four digit code can be found on the last page of this manual. Please remove this page from the manual and store it in a safe place outside of the vehicle.

To enter the code, turn the key to the ON or ACC position and press the ON/VOL control. The word CODE will appear on the display. Enter your four digit code by pressing the appropriate preset buttons in sequence. Your radio is now ready for basic operation.

If an invalid code is entered into the radio, the radio will allow two more attempts. After a third attempt of entering an invalid code, the radio will go into a lockup mode. This is to prevent continuous attempts at entering the wrong code until the right code is found.

Once a radio is in this lockup mode, it must be in a state where battery is applied for approximately 30 minutes. During this time, if the radio is on, the display will show "WAIT". After approximately 30 minutes, (radio on) radio will display "CODE" thereby again querying the operator for the 4 digit anti-theft code.

Operating Instructions - Radio Mode

NOTE: Power to operate the radio is supplied through the ignition switch. It must be in the ON or ACC position to operate the radio.
