Tachometer The tachometer The tachometer displays the approximate engine revolutions per minute (rpm), or how fast the engine is running. The white zone shows the highest number of engine revolutions per minute (rpm) at which you should drive your car. Driving with the pointer in the red zone may cause engine damage. Battery Voltage Gauge (If Equipped) This gauge shows you the battery voltage when the ignition key is in the ON position. If the battery is operating under cold weather conditions, the pointer may indicate in the upper range of the NORMAL band while the battery is charging. If you are running electrical accessories with the engine off or idling at a low speed, or the battery is not fully charged, the pointer may move toward the lower end of the NORMAL band. If it stays outside the NORMAL band, have your vehicle's electrical system checked as soon as it is safely possible. 76
