Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of four 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).
Towing a trailer in the overheat protection mode
should be avoided.

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 indicator. See "Engine Oil, When to
Change" in the Index.
