Windows: Testing and Inspection

Power Window Regulator For Comfort System (automatic Opening And Closing) With Excess Force Limitation (pinch Protection)

With introduction of comfort window regulator, front window regulators are equipped in addition with automatic opening and closing functions.

Switch for automatic opening and closing for front windows are located in drivers door operating unit. Switches for driver and passenger door are equipped with a two-step function.

When respective switch is pressed or pulled to first step, front window manually opens or closes.

When switch is pressed or pulled completely to second step, front window automatically opens or closes.

NOTE: After disconnecting and connecting vehicle battery, automatic opening and closing of drivers and passengers door is without function.

In order to restore this function after connecting battery, proceed as follows:

- Lock vehicle from outside using drivers or front passengers door.

When doing this, make sure that all doors and windows are completely closed.

- Unlock vehicle and lock again via drivers or passengers door. While doing this, hold key in lock position for at least one second.

Automatic opening and closing of drivers and passengers window is re-activated.

If there is a malfunction of electrical window regulator, this is indicated by blinking of switch lights in drivers and passengers door as well as rear doors.

All lights in door trim will flash for approx. 15 seconds after switching on ignition.
