Voltmeter NOTICE Do not drive the vehicle with the oil pressure below the normal range until the cause is fixed-it may ruin the engine. Tachometer The voltmeter tells whether the battery is charged or discharged. Check it while the engine is running-the needle should always indicate as shown above. If the needle reads below or above the normal range while the engine is running, it indicates the charging system needs immediate repair. However, it is normal for the needle to drop below the normal range during engine starting. The tachometer indicates engine speed in thousands of rpm (revolutions per minute). Use it while driving to select correct shift points and to prevent engine lugging and overrevving. Driving with the engine running too fast causes excessive engine wear and poor fuel economy. Remember, in most cases the slower the engine speed, the greater the fuel economy. NOTICE Do not let the indicator needle get into the red zone. This may cause severe engine damage. 93
