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 
to
activate recirculation.
The air quality sensor system does not protect against carbon monoxide (CO), which you cannot see or smell. See Engine Exhaust.
