If the coolant is not at the proper level, repeat Steps 1 through 4, then reinstall the pressure cap. If the coolant is not at the proper level when the system cools down again, see your dealer/retailer. Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. You may decide not to lift the hood but to get service help right away. See Roadside Assistance Program on page 7-7. If you do decide to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running your engine without coolant is not covered by your warranty. See Overheated Engine Protection Operating Mode on page 5-41 for information on driving to a safe place in an emergency. Notice: If the engine catches fire while driving with no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty. See Overheated Engine Protection Operating Mode on page 5-41 for information on driving to a safe place in an emergency.

See Engine Coolant Temperature Gage on page 3-43. The vehicle may also display a COOLANT OVER TEMPERATURE message on the Driver Information Center (DIC).
