Main Menu Table Of Contents Gauges Fuel Gauge This shows how much fuel you have. It may show slightly more or less than the actual amount. Temperature Gauge This shows the temperature of the engine's coolant. During normal operation, the reading should rise to about the middle of the gauge. In severe driving conditions, such as very hot weather or a long period of uphill driving, the reading may rise into the upper half of the gauge. If it reaches the red (Hot) mark, pull safely to the side of the road. See page 347 for instructions and precautions on checking the engine cooling system. Avoid driving with an extremely low f uel level. Running out of f uel could cause the engine to misf ire, damaging the catalytic converter. 70 2009 Civic Sedan
