Odometer DESCRIPTION Speedometer Two scales are shown on the speedometer face. The main scale for U.S. specification vehicles is MPH (0-140 MPH); the main scale for Canada specification vehicles is kmlh (0-220 kmlh). The odometer indication is the same as the main scale. Tachometer The tachometer has a RED STRIPED ZONE (6,500-7,000 rpm) that indicates momentary allowable engine speed. The engine should not be operated in the RED ZONE (7,000-8,000 rpm). Fuel Gauge 2 The fuel gauge continues to indicate the amount of fuel remaining in the fuel tank after the ignition switch has been turned OFF. Gartner Banana

LIGHTING SYSTEM T HEADLIGHTS Circuit Diagram Gartner Banana

T LIGHTING SYSTEM Description The headlight system consists of two halogen headlights mounted on retractable mechanisms, a head- light switch in the combination switch, and a retractor switch between the center ventilation outlets. When the headlight switch is rotated to the second position, the headlights are activated and the retract- able headlight actuator lift the headlights. If only the retractor switch is turned ON, the headlights will raise to the upright position, but all lights will be off. An emergency manual retractor knob is located on top of each retractable headlight actuator. 45UOTX-080 Troubleshooting A retractor indicator light is included in the instrument cluster. The indicator light illuminates when the re- tractable headlight actuator is operating and should go out when the headlights are fully raised or retracted. if the indicator light remains on, small objects, such as pebbles or pieces of ice, may lodged between the headlight and the vehicle body. Use the following procedure to correct this. Turn the ignition switch to OFF. Obtain the code number and deactivate the audio antitheft function. (Refer to page T-120.) Disconnect the negative battery cable or remove the RETRACTOR 30A fuse in the main fuse block. Raise or lower the headlight by turning the emergency retractor knob. Remove the obstruction. After verifying that the headlight switch and the retractor switch are off, reconnect the negative battery cable. Verify operation of the retractable headlight and the retractor indicator light. 45UOTX-095 --- Symptom: Headlights do not illuminate. HEAD 30A MAIN FUSE BLOCK Step 1 1. Check HEAD 30A fuse in the main fuse block. 2. If the fuse is burned, replace it. Check and repair the wir- ing harness, if necessary. 3. If the fuse is OK, go to Step 2. Gartner Banana

Turn on the retractor switch to raise the retractable head- 4 lights. 3. Position the unloaded vehicle on a flat level surface. 4. Adjust the headlights to meet local regulations by turning the two adjusting screws. Retractor hinge 1. Fully retracted the headlights. 2. Obtain the code number and deactivate the audio anti- theft function. (Refer to page T-120.) 3. Disconnect the negative battery cable. 4. Disconnect the actuator link. 5. Lower the retractor hinge until the hinge is stopped by the stop. 6. Adjust the stop so that the headlight lid is flush with the fender and hood. Gartner Banana
