Reinitialisation
If a window does not rise automatically, after reconnecting the battery
for example, its operation must be reinitialised:
 pull the switch until the window stops,
 release the switch and pull it again until the window closes fully,
 continue to hold the switch for approximately one second after the
window has closed,
 press the switch to lower the window automatically to the low
position,
 when the window has reached the low position, press the switch
again for approximately one second.
The safety anti-pinch function is not operational during these
operations.
Always remove the key from the ignition when leaving the vehicle,
even for a short time.
If an obstacle is encountered during operation of the electric
windows, you must reverse the movement of the window. To do
this, press the switch concerned.
When the driver operates the switch for the passenger's electric
window, they must ensure that no one is preventing correct
closing of the windows.
The driver must ensure that the passengers use the electric
windows correctly.
Be aware of children when operating the windows.
