8-6 Climate Controls
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the
automatic climate control system
may not work properly.
Air Quality Sensor
If equipped with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside the 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
@ 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 9-22. The air quality sensor
operation can be adjusted, See
“Climate and Air Quality” under
Vehicle Personalization on
page 5-47.
Rear Climate Control
System
If equipped, the rear climate control
system is on the rear of the center
console. The settings can be
adjusted with the rear climate
control buttons and the touch
screen.
