Overheated Engine Protection Operating Mode
If an overheated engine condition exists and the message ENGINE OVERHEATED STOP ENGINE is displayed, 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 the vehicle to be driven to a safe place in an emergency.
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. See Engine Oil.
