The heated outside rearview mirrors will turn on to help
clear fog or frost from the surface of the mirror when the
rear window defogger is on.
Notice: Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Sensors
The solar sensor, located in the defrost grille, middle of
the instrument panel, monitors the solar radiation. Do
not cover the solar sensor or the system will not work
properly.
There is also an interior
temperature sensor
located next to the
steering wheel that
measures the temperature
of the air inside the
vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside air
temperature and helps maintain the temperature inside
the vehicle. Any cover on the front of the vehicle could
cause a false reading in the displayed temperature.
