Instrumentation Tachometer Indicates the engine speed in revolutions per minute. Driving with your tachometer pointer at the top of the scale or in the red zone may damage the engine. Battery voltage gauge This shows the battery voltage when the ignition is in the ON position. If the pointer moves and stays outside the normal operating range (as indicated), have the vehicle's electrical system checked as soon as possible. 18 8 Engine oil pressure gauge This shows the engine oil pressure in the system. Sufficient pressure exists as long as the needle remains H in the normal range (the area between the "L" and "H"). If the gauge indicates low pressure, stop the vehicle as soon as safely L possible and switch off the engine immediately. Check the oil level. Add oil if needed (refer to Engine oil in the Maintenance and care chapter). If the oil level is correct, have your vehicle checked at your dealership or by a qualified technician. 19
