Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation. If an
overheated engine condition exists, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In this mode, you
will notice a signi cant loss in power and engine
performance. The REDUCED POWER STOP WHEN
SAFE message will come on in the Driver Information
Center (DIC), along with the engine coolant temperature
warning light on the instrument panel, to indicate the
vehicle has entered overheated engine protection
operating mode. The temperature gage will also indicate
an overheat condition exists. Driving extended miles (km)
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. SeeEngine Oil on page 5-15.
