Opening and closing

The power windows may be operated from terminal R ON. When terminal R is OFF the power windows can still be operated for a further minute (encoded in the CAS for deactivation of off-load current violation).

The power windows cannot be operated if one of the front doors is open (dependent on coding).

The side windows can be opened and closed using the following control units:

All the power window switches have two switch levels in either operating direction.

At the first switch level, the side window is opened or closed all the while the switch is pressed.

At the second switch level, the side window is opened or closed fully even after the switch has been released (one-touch opening and closing).

The power window drive runs at higher speed during one-touch opening or closing.

One-touch opening/closing is only possible with the anti-trap function activated.

To ensure that the side windows are securely closed, the power window motors are briefly moved to the locked position (mechanical final stop) end in the upper stop.
