The vehicle has an engine coolant temperature gauge on the instrument cluster and overheat messages in the Driver Information Center (DIC) to warn of engine overheating. See Engine Coolant Temperature Gauge. The DIC also displays overheat messages.
The decision may be made not to lift the hood when the engine coolant temperature gauge is in the overheat zone or an engine overheat DIC message displays, but instead to get service help right away. See Roadside Assistance Program.
If the decision to lift the hood is made, 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.
Caution
Do not run the engine if there is a
leak in the engine cooling system. This can cause a loss of all coolant and can damage the system and vehicle. Have any leaks fixed right away. |
If Steam Is Coming from the Engine Compartment
Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot. Wait for the cooling system and pressure cap to cool. |
If No Steam Is Coming from the Engine Compartment
If the engine coolant temperature gauge is in the overheat zone or an engine overheat DIC message is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle:
If the engine coolant temperature gauge is in the overheat zone and an overheat DIC message is displayed with no sign of steam:
If the engine coolant temperature gauge is no longer in the overheat zone or an overheat DIC message no longer displays, the vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes.
Keep a safe distance from the vehicle in front. If the engine coolant temperature gauge does not go back to the overheat zone or an overheat DIC message does not display, continue to drive normally and have the cooling system checked for proper fill and function.
If the engine coolant temperature gauge is still in the overheat zone or an overheat DIC message still displays, pull over, stop, and park the vehicle right away. If overheat messages appear repeatedly, see your dealer.
If there is no sign of steam, idle the engine for three minutes while parked. If the engine coolant temperature gauge is still in the overheat zone or an overheat DIC message displays, turn off the engine until it cools down.
