Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See “Roadside
Assistance” and “Recreational Vehicle Towing” in
the Index.
Engine Overheating (Gasoline Engine)
You will find a coolant temperature gage on your
vehicle’s instrument panel. See “Engine Coolant
Temperature Gage” in the Index.
If your vehicle has a diesel engine, see “Engine
Overheating” in the Diesel Engine Supplement.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
REDUCED ENGINE POWER light 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 your vehicle to be driven to
a safe place in an emergency. 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 and change the oil. See
“Engine Oil” in the Index.
