ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.

ment on the diagnostics connection is

may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop

Never leave children unattended in the vehi-
cle. 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 from trav-
elling upwards during the automatic closing process, the side window opens again auto-
matically. During the manual closing process,
the side window only opens again automati-
cally after the corresponding switch is
released. The automatic reversing feature is
only an aid and is no substitute for your atten-
tion when closing a side window. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R while resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing, make sure that no parts of the
body are in the closing area. If someone
becomes trapped, press the switch to open
the side window again. Opening and closing the side win-

Panorama sliding sunroofOpening and closing

!
Only open the panorama sliding sunroof if
it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the sliding sunroof. Otherwise, the seals could
be damaged.
i Resonance noises can occur in addition to
the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises. Sliding sunroof reversing feature
The sliding sunroof is equipped with an auto- matic reversing feature. If an object blocks or
restricts the sliding sunroof during the closing process, the sliding sunroof opens again
automatically. The automatic reversing fea-
ture is, however, only an aid and is no substi-
tute for your attention when closing the slid-
ing roof. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 4 mm of the closing movement
R during resetting
R when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing function cannot prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area.
If someone is trapped:
R release the switch immediately or
R during automatic operation, press the
switch briefly in any direction
