Operating
Manual up/down
Auto up/down.
All power windows can be operated using the control panel in the driver's door. The control panels in the other doors
only operate the window in the respective doors.
For the power windows to function, the ignition must be in at least mode I. When the vehicle has been running, the
power windows can be operated for several minutes after the remote key has been removed from the ignition slot, or
until a door has been opened.
NOTE
Movement of the windows will stop if they are obstructed in any way.
To reduce buffeting wind noise if the rear windows are opened, also open the front windows slightly.
Manual up/down
Move one of the controls up/down gently. The power windows move up/down as long as the control is held in
position.
Auto up/down
Move one of the controls up/down as far as possible and release it. The window will open or close completely.
Resetting
If the battery has been disconnected, the auto open function must be reset so that it will work properly.
1. Gently raise the front section of the button to close the window and hold it for one second.
2. Release the button briefly.
3. Raise the front section of the button again for one second.
