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
automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility to pay 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 over the last 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 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
becomes trapped, press the switch to open
the side window again. Opening and closing the side win-

If you close a side window again immediately
after it has been blocked or reset, the side
window closes with increased or maximum
force. The reversing function is then not

increased risk of injury or even fatal injury.
Make sure that no parts of the body are in the
closing area. To stop the closing process,
release the switch or push the switch again to
reopen the side window.
Problem: a side window cannot be closed
because it is blocked by objects, e.g.
leaves in the window guide.

Important safety notes
In
the following section, the term "sliding sun-
roof" refers to the panorama sliding sunroof. G
WARNING
While opening and closing the sliding sunroof,
body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity

during the opening and closing pro-
cedures.
If somebody becomes trapped:
R release the switch immediately, or
R during automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop-

could
become trapped, particularly if they are
left unsupervised. 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
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.

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 86

Seats
Important safety notes
G
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
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
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 and
thereby 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
system. G
WARNING
When adjusting a seat, you or another vehicle
occupant
could become trapped by the guide
rail 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
adjusting it. G
WARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
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.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position. G
WARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted

correctly. There is an increased risk
of injury to the head and neck in the event of
an accident or sudden braking, for example.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when moving Seats
