Sensors
The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor
or the system will not work properly.
There is also an exterior
temperature sensor 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.
Climate Controls
The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the outlet temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be used as needed to maintain cool
outlet temperatures.
Rear Climate Control
System
If equipped, the rear climate control
system is on the rear of the center
console storage. The rear climate
settings can be adjusted with this
system.
