Overheated Engine Protection
Operating Mode
The overheated engine protection operating mode
allows the vehicle to be driven to a safe place in an
emergency situation. If an overheated engine
condition exists, this protection mode alternates
ring groups of cylinders to help prevent engine
damage. In this mode, there will be a signi cant
loss in power and engine performance. The engine
coolant temperature gage indicator will move to the
shaded area, and the engine coolant temperature
warning light will come on, showing that an
overheated engine condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheated engine 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.
