proximity during the opening and closing pro-
cedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the

!The weather can change abruptly. It couldstart to rain or snow. Make sure that the slid-ing sunroof is closed when you leave the vehi-cle. The vehicle electronics can be damaged ifwater enters the vehicle interior.
Resonance noises can occur in addition to theusual airflow noises when the sliding sunroof isopen. They are caused by minor pressure fluc-tuations in the vehicle interior. Change the posi-tion of the sliding sunroof or open a side windowslightly to reduce or eliminate these noises.
Sliding sunroof reversing feature
The sliding sunroof is equipped with an auto-matic reversing feature. If a solid object blocks
or restricts the sliding sunroof during the closingprocess, the sliding sunroof opens again auto-matically. The automatic reversing feature isonly an aid and is no substitute for your attentionwhen closing the sliding roof.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in (4 mm) of the closing
movement
Rduring resetting
Rwhen closing the sliding sunroof 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.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the

side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive Highbeam Assist is only an aid. You areresponsible for adjusting the vehicle's lightingto the prevailing light, visibility and traffic con-ditions.
In particular, the detection of obstacles can beimpaired if:
Rthere is poor visibility, e.g. due to fog, heavyrain or snow
Rthere is dirt on the sensors or anything elsecovering the sensors
