Sensors
The solar sensor, located in the defrost grille, 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 interior
temperature sensor
located next to the steering
wheel that measures the
temperature of the air
inside your 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.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the 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.
