Instrumentation Engine coolant temperature gauge Indicates the temperature of the engine coolant. At normal operating temperature, the needle remains within the normal area (the area between the "H" and "C"). If it enters the red section, the engine is overheating. Stop the vehicle as soon as safely possible, switch off the engine immediately and let the engine cool. Refer to Engine coolant in the Maintenance and care chapter. H C Never remove the coolant reservoir cap while the engine is running or hot. This gauge indicates the temperature of the engine coolant, not the coolant level. If the coolant is not at its proper level the gauge indication will not be accurate. Tachometer (if equipped) Indicates the engine speed in revolutions per minute. Driving with your tachometer pointer continuously at the top of the scale may damage the engine. 4 3 2 1 0 5 6 RPMx1000 13
