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 ignition and let it cool. Refer to Engine coolant in the Maintenance and care chapter. Never remove the coolant recovery cap while the engine is running or hot. • Standard instrument cluster H TEMP C • Optional instrument cluster H N O R M C 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. If the gauge enters the red section, the engine coolant and Check Engine/Service Engine Soon indicators illuminate, refer to What you should know about fail-safe cooling in the Maintenance and care chapter. 15
