Towing Your Vehicle

Consult your dealer or a professional towing service
if you need to have your disabled vehicle towed.
See "Roadside Assistance" in the Index. If you
want to tow your vehicle behind another vehicle for
recreational purposes (such as behind a motorhome),
see "Recreational Vehicle Towing" in the Index.

Engine Overheating

You will find a coolant temperature gage and a warning
message about a hot engine on your instrument panel
cluster. See "Engine Coolant Temperature Gage" and
"Hot Coolant Temperature Message" in the Index.
You also have a low coolant message on your instrument
panel cluster. See "Low Coolant Level Message" in

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 firing groups of
cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The low coolant light may come on and
the temperature gage will 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. See "Engine Oil" in the Index.
