Instrument Cluster 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 and the multiĆfunction warning light illuminates, refer to How fail safe cooling works in coolant in the Maintenance and Specifications chapter. Never remove the coolant reservoir cap while the engine is running or hot. Fuel gauge Displays approximately how much fuel is in the fuel tank (when the key is in the ON/RUN position). The fuel gauge may vary slightly when the vehicle is in motion. The ignition should be in the OFF position while the vehicle is being refueled. When the gauge first indicates empty, there is a small amount of reserve fuel in the tank. When refueling the vehicle from empty indication, the amount of fuel that can be added will be less than the advertised capacity due to the reserve fuel. If the key is not in the OFF position when you refuel the vehicle, the fuel gauge will not indicate the new volume until the ignition is turned OFF and then to ON/RUN. 20
