Function prerequisites

 Voltage not too low or too high

 Ignition key in position "0" or removed

 All doors closed

 Press "Lock vehicle" or "Unlock vehicle" button on remote control key for longer than 1 s

Convenience closing function
Pressing the "Lock vehicle" button on the remote control key (A8/1) triggers the corresponding function of the central locking. If the button is pressed for more than 1 s the remote control key sends an infrared (IR) signal for convenience closing. The signal is received by the left front door IR receiver (A26/1) or right front door IR receiver (A26/2).

When the function prerequisites are fulfilled the left front door control module (N69/1) or right front door control module (N69/2) transfers the command for convenience closing to the CAN bus. The CAN messages are received by the overhead control panel control module (N70) as well as by the other door control modules. These control modules actuate the sliding/pop-up roof convenience closing and power window convenience closing functions. On model 215 the left and right rear power window motors are actuated by the rear control module (N22/6).

Convenience opening function
When the "Unlock vehicle" button is pressed the corresponding functions for convenience opening are accomplished. In addition the seat ventilation function (special equipment) is started by the seat control modules for 5 minutes.

 The excessive force limitation feature for the power windows and the SR is not active in combination with the convenience closing feature.
