Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
messages COOLANT OVER TEMP and REDUCED
ENGINE POWER are displayed, along with the Check
Engine light, an overheat protection mode which
alternates firing groups of cylinders helps prevent engine
damage. In this mode, you will notice a loss in power
and engine performance. This operating mode
allows your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).
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 5-13.
