GWARNING
If objects, luggage or loads are not secured
or not secured sufficiently, they could slip,
tip over or be flung around and thereby hit
vehicle occupants. There is a risk of injury,
particularly in the event of sudden braking
or a sudden change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
!The tailgate swings upwards and to therear when opened. Therefore, make surethat there is sufficient clearance above andbehind the tailgate.
The opening dimensions of the tailgate can befound in the "Vehicle data" section(Ypage 339).

Tailgate obstruction detection with
reversing feature
On vehicles with an EASY-PACK tailgate, thetailgate is equipped with automatic obstaclerecognition with a reversing feature. If a solidobject blocks or restricts the tailgate whenautomatically opening or closing, this proce-dure is stopped. If the tailgate is stopped dur-
ing the closing process, the tailgate automati-cally opens again slightly. The automaticobstruction detection with reversing feature isonly an aid. It is not a substitute for your atten-tiveness when opening and closing the tail-gate.
GWARNING
The reversing feature does not respond:
Rto soft, light and thin objects, e.g. fingers
Rover the last 1/3 in (8 mm) of the closing

you could burn yourself by touching the
exhaust system. There is a risk of injury.
Always ensure that you make the kicking
movement only within the detection range of
the sensors.
!If the SmartKey is within the rear detectionrange of KEYLESS-GO, the following situa-tions, for example, could lead to the unin-tentional opening of the tailgate:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least10 ft (3m) away fromthe vehicle.

Rto soft, light and thin objects, e.g. fingers
Rover the last 1/6 in (4 mm) of the closing
path
Rwhile adjusting
Rwhen closing the sliding sunroof again
manually immediately after automatic
reversing
This means that the reversing feature can-
not prevent someone being trapped in these
situations. There is a risk of injury.
