WARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the SmartKey with you and lock the vehi-
cle. Never leave children unsupervised in the
vehicle. Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a side window during the closing
process, the side window opens again automat-
ically. However, the automatic reversing feature is only an aid and does not relieve you of the
responsibility of paying attention when closing a side window. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 1/6 in(4 mm) of the closing
movement
R during resetting
R when closing the side window again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.

proximity during the closing procedure. If
someone becomes trapped, press the switch to open the side window again. Opening and closing the side win-
