Cadillac 2015 - CRC manual Overheated Engine Protection Operating Mode

10-20 Vehicle Care

Warning (Continued)

If you keep driving when the engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine

is 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:

.Climbs a long hill on a hot day.

.Stops after high-speed driving.

.Idles for long periods in traffic.

.Tows a trailer.

If the overheat warning is displayed with no sign of steam:

1.Turn the air conditioning off.

2.Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.

3.When it is safe to do so, pull off the road, shift to P (Park) or

N (Neutral), and let the engine idle.

If the temperature overheat gauge is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle distance from the car in front of you. 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. Also, see “Overheated Engine Protection Operating Mode” next in this section.

In this mode, there is significant loss in power and engine performance.

The engine coolant temperature warning light comes on in the instrument cluster, to indicate the vehicle has entered overheated engine protection operating mode. The temperature gauge also
