• Do not use the winter grille cover when temperatures are above 50°F
(10°C). Use of the cover in these conditions could cause your vehicle
to overheat. If this happens while the cover is being used, remove the
cover and store properly.
• Do not use the winter grille cover above 32°F (0°C) if towing a trailer.
The added power needed to tow a trailer requires the radiator grille to
have full airflow under all conditions. Your vehicle may overheat if the
cover is used while towing a trailer.
• Do not modify the winter grille cover. The winter grille cover does not
block some sections of the front of the vehicle because these openings
are needed to provide enough airflow to the radiator and air cooler in
extremely cold temperatures.
Installation instructions
The “Installation Instructions” included with your winter grille cover
packaging explain how to install and remove your vehicle’s winter grille
cover. When installing or removing the winter grille cover, refer to the
“Usage guidelines” listed previously. When you first attempt to fit the
winter grille 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 winter
grille cover is best performed when the cover is warm.
Engine block heater (if equipped)
Refer to the Driving chapter in the Owner’s Guide.
Rapid Heat supplemental heating system (if equipped)
The optional Rapid Heat feature is an electrically powered device that is
designed to provide supplemental heat during engine warm up. For
maximum effectiveness mid to low blower speed is recommended during
initial warm up. When operating in automatic mode (when equipped) the
climate control unit will determine the appropriate blower speed for
existing conditions.
Note: Additional aftermarket electrical loads operated during engine
warm up may impact the performance of the Rapid heat supplemental
heater.
