Driving and Operating 251
When thehindicator is
illuminated, the system is
enabled.
Winter Cover
If equipped, the winter cover
can be used to enhance
heater performance in
extremely cold conditions
below −0 °C (32 °F). The winter
cover installs over the grille
and restricts airflow to the
engine compartment.
Usage Guidelines
The winter cover should only
be used while operating the
vehicle in extremely cold
temperatures or in heavy
snow for extended periods. In
these temperatures, the
vehicle does not need a large
amount of air to properly cool
the engine. When more airflow
is required to cool the vehicle,
the winter cover should not be
used. The following usage
guidelines will allow adequate
airflow for proper radiator and
air cooler performance:
.Do not use the winter cover
if towing a trailer. The
vehicle may overheat if the
radiator is covered while
towing.
.Do not modify the cover. The
winter cover does not cover
some sections of the front
of the vehicle to provide
enough airflow.
.Keep the underside of the
winter cover as clean as
possible. Remove monthly or
as necessary and clean away
dust and debris.
.Do not use the winter cover
above −0 °C (32 °F).
Use only a mild soap to clean.
Do not use harsh soap, strong
detergents, or vinyl
protectant/sealant type
products as they may damage
the special finish. Allow the
winter cover to dry completely
before reinstalling.
Installation Instructions
When first trying to fit the
cover, it may appear to be
undersized but will stretch
during installation to ensure a
tight fit. The initial installation
of the cover is best performed
when the winter cover
is warm.
1. Center grille cover and make sure that it is
positioned correctly.

2. Push plastic hooks back toengage grille slats. It is
recommended to start with
the lower hooks at the
center of the grille.
3. Repeat for all hooks to fully engage cover to grille.
For vehicles equipped with
a front license plate
bracket, only the outer
clips will be engaged on
the upper row. Ensure the
top center portion of the
cover is positioned
securely behind the license
plate bracket. 4. Make sure all clips remain
engaged during
installation. Cover should
be stretched to a tight fit
when properly installed.
Engine Heater
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 heater
operation at temperatures
above −18 °C (0 °F).
{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

Driving and Operating 253
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.
3. Plug it 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.
.Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
(Continued)
Warning (Continued)
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(Continued)
Warning (Continued)
the cord. Keep the cord
away from any moving
parts.
4. Before starting the engine, be sure to unplug and
store the cord as it was
before to keep it away
from moving engine parts.
If you do not it could be
damaged.
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.
