♦
The Air Quality Sensor - G238- contains a highly sensitive
electronic component that can be damaged if it comes in direct
contact with solvents, fuels or chemicals.
♦
Do not install a sensor that has been kept, for example, in a
tool box.
♦
Do not store removed sensors in areas where they can come
into contact with solvents, fuels and certain chemical compo‐
sitions (fluids or vapors).

8.3
Function of Air Quality Sensor - G238-
♦ Sensor for air quality detects pollutants in the ambient air
(mostly gasoline and/or diesel fumes).
♦ The Climatronic Control Module - J255- evaluates the signal
from the Air Quality Sensor - G238- . The Air Conditioning (A/
C) system is activated depending on the strength and type of
heavily polluted air.
At an outside temperature above approximately 2 °C (35.6 °F) the
recirculating air mode is switched on when there is only a slight
increase in pollutants in the ambient air.
