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 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 263 for instructions and precautions on checking the engine cooling system. Check Fuel Cap Message Your vehicle's on board diagnostic system will detect a loose or missing fuel fill cap as an evaporative system leak. The first time a leak is detected a ''CHECK FUEL CAP'' message appears on the information display. Turn the engine off, and confirm the fuel fill cap is installed. If it is, loosen it, then retighten it until it clicks at least once. The message should go off after several days of normal driving once you tighten or replace the fuel fill cap. To scroll to another display, press the SEL/RESET button. The ''CHECK FUEL CAP'' message will appear each time you restart the engine until the system turns the message off. Instruments and Controls 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. CONTINUED 67
