Important safety notes

When opening or closing the door windows, WARNING
When opening or closing the door windows, make sure that there is no danger of anyone being harmed by the opening/closing procedure.
The door windows are equipped with automatic operation and the anti-entrapment feature. If in automatic mode a door window encounters an obstruction that blocks its path, the anti-entrapment feature will stop the door window and open it slightly.
The door windows operate differently when the switch is pulled. See the "Problems with door windows" section for details.
The closing of the door windows can be immediately halted by releasing the switch or, if the switch was pulled past the resistance point and released, by either pressing or pulling the respective switch.
If a door window encounters an obstruction that blocks its path in a circumstance where you are closing the windows by pressing and holding the button on the SmartKey or button on the SmartKey or by pressing and holding the lock button (vehicles with KEYLESS-GO) on an outside door handle, the anti-entrapment feature will not operate.
Activate the override switch when children are riding in the back seats of the vehicle. The children may otherwise injure themselves, e.g. by becoming trapped in the door window opening.

Do not keep any part of your body up against WARNING
Do not keep any part of your body up against the window pane when opening a window. The downward motion of the pane may pull that part of your body down between the window pane and the door frame and trap it there. If there is a risk of entrapment, release the switch and pull it to close the window.
