Driving and Operating
Engine Heater
{
Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport.
Property damage or personal injury may
result. Always park the vehicle in a clear
open area away from buildings or
structures.
The engine heater, if available, can help in
cold weather conditions at or below
−
18 °C
(0 °F) for easier starting and better fuel
economy during engine warm-up. Plug in
the engine heater at least four hours before
starting the vehicle. An internal thermostat
in the plug end of the cord will prevent
engine coolant heater operation at
temperatures above
−
18 °C (0 °F).
To Use the Engine Heater
1. Turn off the engine.
2. Remove the heater cord from the rear
compartment.
3. Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
4. Plug the cord into the receptacle in the
front fascia.
5. Plug the other end of the cord into a
normal, grounded 110-volt AC outlet.

Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.
Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could
cause an electric shock.

Warning (Continued)
.
Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.
Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.
.
While in use, do not let the heater
cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
.
Before starting the vehicle, unplug the
cord, reattach the cover to the plug,
and securely fasten the cord. Keep the
cord away from any moving parts.
The length of time the heater should remain
plugged in depends on several factors. Ask a
dealer in the area where you will be parking
the vehicle for the best advice on this.
