The vehicle has an engine coolant temperature gauge to warn of the engine overheating. See Engine Coolant Temperature Gauge
If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program
If the decision is made 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. 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 an engine overheat warning 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 overheat warning is displayed with no sign of steam:
If the engine coolant temperature gauge is no longer in the overheat zone, the vehicle can be driven.
Continue to drive the vehicle slowly for about 10 minutes. Keep a safe vehicle distance from the vehicle in front. If the warning does not come back on, continue to drive normally and have the cooling system checked for proper fill and function.
If the warning continues, pull over, stop, and park the vehicle right away.
If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down.
