If the LOW COOLANT message does not appear on the Driver Information Center (DIC) after two minutes, the coolant is at the proper fill level. If a LOW COOLANT message does appear, repeat Steps 1 through 3 then reinstall the pressure cap, or see your dealer/retailer. If coolant is needed, add the proper DEX-COOL® coolant mixture at the coolant surge tank. 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. The coolant surge tank pressure cap must be fully installed on the coolant surge tank. See Engine Compartment Overview on page 6-12 for more information on location. There is also an engine coolant temperature gage on the instrument panel cluster. See Engine Coolant Temperature Gage on page 3-49. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Service on page 8-7. 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 fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered by the warranty. 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 6-29 for information on driving to a safe place in an emergency. Engine Overheating The vehicle has several indicators to warn of engine overheating. There is a COOLANT OVER TEMP message or an ENGINE HOT, STOP ENGINE message displayed in the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-60. You will also hear a chime. 6-27
