Voltmeter Tachometer NOTICE Do not let the indicator needle get into the red zone. This may cause severe engine damage. 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. It is not a malfunction even if the needle of the voltmeter returns to "9" when the ignition switch is turned to the "START" position. The tachometer indicates engine speed in thousands of rpm (revolutions per minute). Use it while driving to prevent engine over-revving. 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. It is not a malfunction even if the needle of the tachometer returns to "0" when the ignition switch is turned to the "START" position. 120
