with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
At high speeds the sliding sunroof automati-
cally lowers slightly at the rear. This could trap you or other persons. There is a risk of injury.Make sure that nobody reaches into the
sweep of the sliding sunroof whilst the vehicle
is in motion.
If somebody becomes trapped, reduce speed
immediately, paying attention to road and
traffic conditions. The sliding sunroof opens
again to its original position.
If the maximum position is not reached, you
can raise it further.
! 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

The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts the sliding sunroof during
the closing process, the sliding sunroof opens again automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility to pay atten-
tion when closing the sliding sunroof. G

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-

WARNING
If children adjust the seats, they could
become trapped, especially if they are unat-
tended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING

Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G
WARNING
When adjusting a seat, you or another vehicle occupant could become trapped by the guiderail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when

upright position. When braking or in the event
of an accident, you could slide underneath the
seat belt and sustain abdomen or neck inju-
ries, for example. This poses an increased risk of injury or even fatal injury.

Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off.
