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.
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.
Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Adjustable air vents are in the
center and on the sides of the
instrument panel, and on the
rear of the center console
storage.
Move the slider knobs to
change the direction of or to
close off the airflow.
