Component Identification:

General
The convenience feature (CF) includes the following functions
^ Convenience closing/opening with transmitter key
^ Convenience opening/closing via recirculated air
^ Convenience closing via Keyless Go (with code (889) Keyless Go)

The convenience opening/closing function opens and closes
^ the windows
^ the tilting/sliding roof (with code (414) Power glass tilting/sliding roof)
^ the panoramic glass roof with roller blinds in roof (on model 221.1 with code (413) Panoramic sliding roof with top sliding roof)
^ the rear side roller blinds (with code (297) Roller sun blind in rear doors)

Vehicles up to 31.5.07:
The front windows and the roller sun blinds are opened first. When reactuated, the rear windows and the tilting/sliding roof or panoramic roof open.

Vehicles as of 1.6.07:
The roller sun blinds are opened first. When reactuated, the rear windows and the tilting/sliding roof open.

Activation sequence for convenience closing
The windows and the tilting/sliding roof or panoramic are closed first. When reactuated, the roller sun blinds close.

The roller sun blinds are not actuated via recirculated air during convenience closing/opening.

Convenience feature via transmitter key

Function requirements
^ No transmitter key in EIS control unit
^ Driver door closed

Function
When the "Lock or unlock" button on the transmitter key is pressed and held down (t > 1 s), it transmits an infrared command "Convenience feature" to the driver door infrared sensor. This signal is read in by the left front door control unit and transmitted to the EIS control unit via interior CAN. The EIS control unit checks the access authorization of the transmitter key. If the access authorization is valid, the EIS control unit transmits the "Convenience feature" command via the interior CAN to the door control units, and overhead control panel control unit which actuate the corresponding motors.

When the "Lock or unlock" button is released, the convenience feature is stopped.

Convenience opening/closing via recirculated air button

Function requirements
- Circuit 15 On

Function
When the recirculated air button in the upper control panel control unit is actuated for longer than 1.5 s, the "Convenience actuation" command is transmitted to the door control unit and overhead control panel control unit via the interior CAN. The current positions are stored and convenience closing is performed. When the air recirculation switch is actuated again for longer than 1.5 s, the corresponding windows and tilting/sliding roof are automatically moved the position they were in before convenience closing was started.
A panoramic sliding roof must be moved manually to the desired position.

The convenience feature is immediately stopped when the air recirculation switch is actuated again.

Convenience closing via keyless go

Function requirements
^ No transmitter key in EIS control unit
^ All doors closed

Function
When a comfort sensor is touched (t > 1.5 s), it transmits a signal to the KEYLESS GO control unit. The Keyless Go control unit then transmits the "Convenience actuation" command to the door control units and overhead control panel control unit for the duration of the actuation via the interior CAN

Convenience closing is interrupted in the following cases:
- another comfort sensor is actuated
- another comfort sensor is actuated
- after max. 90 s

If the same door handle is pulled during convenience closing, or max. 2 s therafter, emergency opening is activated. Actuation is performed for min. 2 s or as long as the door handle is pulled, max. 90 s.
