UNDERSTANDING YOUR INSTRUMENT PANEL 227 INSTRUMENT CLUSTER DESCRIPTION 1. Check Gages This light illuminates when the Voltmeter, Engine Oil Pressure or Engine Coolant Temperature gages indicate a reading either too high or too low. Examine the gages carefully, and follow the instructions above for each indicated problem. NOTE: When the ignition switch is turned to OFF, the Fuel Gage, Voltmeter, Oil Pressure and Engine Coolant Temperature gages may not show accurate readings. When the engine is not running, turn the ignition switch to ON to obtain accurate readings. 2. Voltage Gauge 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 system should be serviced. NOTE: If the gauge pointer moves to either extreme of the gauge, the "Check Gages" indicator will illuminate and a single chime will sound. The "Check Gages" indicator may also illuminate prior to the voltage gauge moving out of normal range. In either case, see you local authorized Dealer for system service. 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. 4
