Overheated Engine Protection Operating Mode

This emergency operating mode lets the vehicle be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage.

In this mode, there is a significant loss in power and engine performance. The temperature gauge indicates an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided.

Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair.

The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system.

See Engine Oil on page 10‑8.
