Winter Cover
If the vehicle includes a winter
cover, it can be used to enhance
heater performance in extremely
cold conditions below
−
18°C (0°F).
The winter cover installs over the
grille and restricts air flow to the
engine compartment.
For diesel powered vehicles that
did not come with a winter cover, a
GM winter cover can be purchased
as an accessory. See your dealer
for additional information.
Usage Guidelines
The winter cover should only be
used while operating the vehicle in
extremely cold temperatures or in
heavy snow for extended periods of
time. 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 added
power needed to tow a trailer
requires the radiator grille to
have full airflow under all
conditions. The vehicle may
overheat if the cover is used
while towing a trailer.
.
Do not modify the cover. The
winter cover does not cover
some sections of the front of the
vehicle because these openings
are needed to provide enough
airflow to the radiator grille and
air cooler in extremely cold
temperatures.
.
When the winter cover is used,
the temperature sensor found
on the inside rearview mirror
will not function properly. The
temperature that is shown will
be incorrect.
.
Keep the underside of the winter
cover as clean as possible at all
times. Remove monthly or as
necessary and clean away dust
and debris.
.
Use only a mild soap to clean
the winter cover. Do not use
harsh soap, strong detergents or
vinyl protectant/sealant type
products as they may destroy
the special finish of the winter
cover. Allow the winter cover to
dry completely before reinstalling
on the vehicle.
Installation Instructions
When you first try to fit the cover it
may appear to be undersized.
This is due to the nature of the
special vinyl, which will stretch
during installation to ensure a tight
fit. For this reason, the initial
installation of the cover is best
performed when the winter cover
is warm.
