Climate Controls 8-5
In cold weather the windshield
defroster and/or rear window
defogger automatically turn on.
If the vehicle has heated seats, they
will also turn on.
When the ignition is turned to
ON/RUN, the climate control system
returns to the settings used before
the vehicle was last turned off.
The heated seats will turn off,
if equipped.
Sensors
The solar sensor located on the
instrument panel, near the
windshield, monitors the solar heat.
The interior temperature sensor,
located on the instrument panel to
the right of the steering wheel,
measures the temperature of the air
inside the vehicle.
The climate control system uses the
information from these sensors to
adjust the fan speed and the air
delivery, in order to maintain the
selected temperature. The system
may also supply cooler air to the
side of the vehicle facing the sun.
The recirculation mode will also be
activated, as necessary.
Do not cover the sensors or the
automatic climate control system will
not work properly.
Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate,
such as during cold weather or
with extreme odors. Press
M to
activate recirculation.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust on
page 9‑27.
