Air Quality Calibration Offset

Air Quality Calibration Offset

The Air Quality system will have three Sensitivity levels, Low, Medium, and High. Medium is the default setting in new vehicles.

The Sensitivity Level can be changed through SPS programming. If exhaust fumes are noticed in the vehicle a more sensitive level should be selected.
