  1. Cover for Dust and Pollen Filter Installation Slot
    • There are different versions of the dust and pollen filter. Refer to the Parts Information.
    • Dust and pollen filter replacement interval. Refer to the Maintenance Tables.
    • Dust and Pollen Filter, Removing and Installing. Refer to DUST AND POLLEN FILTER, REMOVING AND INSTALLING .
  2. Interior Rearview Mirror with Humidity Sensor -G355-
    • The Humidity Sensor -G355- is only installed on vehicles with an automatic climate control system
    • Check using the Vehicle Diagnostic Tester in the"Guided Fault Finding"  function (for the Climatronic Control Module -J255- and the Vehicle Electrical System Control Module -J519-). Refer to the appropriate Wiring Diagram.
    • Removing and Installing. Refer to Humidity Sensor -G355-, REMOVING AND INSTALLING .
      NOTE:

      There is neither a Humidity Sensor -G355- nor a Air Quality Sensor -G238- (with the Humidity Sensor in Fresh Air Intake Duct -G657-) installed on vehicles with a manual climate control system. The permissible stop time is currently calculated by characteristic curves that are influenced by the measured exterior temperature, the "Recirculating air mode" function and the operating condition of the windshield wipers. The calculated time must be greater than approximately 20 seconds so that the Stop function is permitted by the Climatronic Control Module -J255-. The stop time can be shortened at a lower exterior temperature, when the recirculating air mode is active and/or when it is raining to prevent the windshield and door windows from fogging up. If the calculated time for the Stop function is less than approximately 20 seconds, it is prevented.

      The Humidity Sensor -G355- is integrated in the Rain/Light Recognition Sensor -G397- and cannot be replaced separately when faulty. Replace the Rain/Light Recognition Sensor -G397- (with the Humidity Sensor -G355-). Refer to OVERVIEW - WINDSHIELD and RAIN/LIGHT RECOGNITION SENSOR, REMOVING AND INSTALLING .

      The removal of the Rain/Light Recognition Sensor -G397- (with the Humidity Sensor -G355-) is described in different assembly groups depending on the vehicle.

  3. Right Side Window Defroster Door Motor -V410- with Right Front Defroster/Upper Body Vent Shut-Off Door Motor Position Sensor -G317-
  4. Vent in Right A-Pillar Trim Panel
  5. Right Instrument Panel Side Vent
  6. Right Footwell Vent
  7. Climatronic Control Module -J255-
    • Removing and Installing. Refer to Climatronic Control Module -J255-, REMOVING AND INSTALLING .
    • There are different versions in vehicles with a manual or automatic climate control system. Refer to the Parts Information
    • The Climatronic Control Module -J255- receives information from the various controls (control heads, regulators and buttons) via data wires or direct wire connections. Refer to the appropriate Wiring Diagram.
    • The A/C system regulation is controlled via the selected presets on the controls. Refer to OVERVIEW - DISPLAY CONTROL HEADS, VEHICLES WITH MANUAL CLIMATE CONTROL SYSTEM and OVERVIEW - DISPLAY CONTROL HEADS, VEHICLES WITH AUTOMATIC CLIMATE CONTROL SYSTEM .
    • Certain presets on the controls are transmitted by the Climatronic Control Module -J255- to secondary control modules via the Data Bus (for example, the activation of the rear window defogger, the seat heating, etc. to the Vehicle Electrical System Control Module -J519-). The Vehicle Electrical System Control Module -J519- reports the change request back to the Climatronic Control Module -J255- and it then activates the indicator lamps in the controls. Use the Vehicle Diagnostic Tester in the"Guided Fault Finding"  function. Refer to the appropriate Wiring Diagram.
    • Check using the Vehicle Diagnostic Tester in the"Guided Fault Finding"  function (for the Climatronic Control Module -J255-). Refer to the appropriate Wiring Diagram.
    • For additional information. Refer to OVERVIEW - DISPLAY CONTROL HEADS, VEHICLES WITH MANUAL CLIMATE CONTROL SYSTEM and OVERVIEW - DISPLAY CONTROL HEADS, VEHICLES WITH AUTOMATIC CLIMATE CONTROL SYSTEM .
      NOTE:

      There is neither a Humidity Sensor -G355- nor an Air Quality Sensor -G238- (with the Humidity Sensor in Fresh Air Intake Duct -G657-) installed on vehicles without an A/C system or with a manual climate control system. The permissible stop time is currently calculated by characteristic curves that are influenced by the measured exterior temperature, the "Recirculating air mode" function and the operating condition of the windshield wipers. The calculated time must be greater than approximately 20 seconds so that the Stop function is permitted by the Climatronic Control Module -J255-. The stop time can be shortened at a lower exterior temperature, when the recirculating air mode is active and/or when it is raining to prevent the windshield and door windows from fogging up. If the calculated time for the Stop function is less than approximately 20 seconds, it is prevented.

    • Equipment level with seat heating (and neck heating)
    • There are different versions. Refer to the Parts Information.
    • Information about the function of seat heating (and neck heating). Refer to SEAT HEATING .
    • Check the activation and function of the seat heating (and neck heating) using the Vehicle Diagnostic Tester in the"Guided Fault Finding"  function (for the Climatronic Control Module -J255- and the Vehicle Electrical System Control Module -J519-). Refer to the appropriate Wiring Diagram.
    • Seat Heating (and Neck Heating), Servicing. Refer to Front Seat Covers and Cushions .
    • Neck Heating, Servicing. Refer to Front Seats .
