Sliding sunroof
Important safety notes
Your vehicle may be equipped with a sliding
sunroof or a panorama roof with power tilt/
sliding panel. In the following section, the
term "sliding sunroof" refers to both types of
sliding sunroof.
GWARNING
When opening or closing the sliding sunroof,
make sure that there is no danger of anyone
being harmed by the opening/closing
procedure.
The sliding sunroof is equipped with
automatic operation and the anti-entrapment
feature. If the movement of the sliding sunroof
is blocked during the closing procedure, the
sliding sunroof will stop and open slightly.
The sliding sunroof operates differently when
the sliding sunroof switch is pressed and held.
See the "Problems with the sliding sunroof"
section for more details.
Sliding sunroof89Opening/closingZ

The opening/closing procedure of the sliding
sunroof can be immediately halted by
releasing the sliding sunroof switch or, if the
sliding sunroof switch was moved past the
resistance point and released, by moving the
sliding sunroof switch in any direction.GWARNING
The sliding sunroof is made out of glass. In the
event of an accident, the glass may shatter.
This may result in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury for
occupants wearing their seat belts properly,
as entire body parts or portions of them may
protrude from the passenger compartment.
! Only open the sliding sunroof if it is free
of snow and ice. Otherwise, malfunctions
may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.
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.

Rear seat head restraints
GWARNING
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
GWARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.

of injury for passengers seated in the rear
compartment.
If you wish to remove the head restraints from
the outer seats in the second row of seats,

you must move the respective seat as far
back as possible (Y page 101). Then, fold the

Adjusting the seats in the 2nd and 3rd
rows
Important safety notes
GWARNING
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belt
provide the best restraint when the wearer is
in a position that is as upright as possible and
the seat belt is properly positioned on the
body.
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Never place hands under the seat or near any
moving parts while a seat is being adjusted.
After adjusting the seat, always ensure that
the seat and the backrest are correctly
engaged. The backrest must be in an upright
position.
An outer seat in the second row is only locked
correctly if lock verification indicator : is
folded in and red marking ; is just visible.
If the seat and backrest are not correctly
latched, the seat could move forward and the
backrest could fold down. While braking,
changing direction, or in an accident, you
could slide under the seat belt. The child seat
would no longer be correctly supported or
correctly positioned and would no longer
carry out its intended function. This could
cause serious or fatal injuries.

allow occupants to use the folded second-row
middle seat as a table while driving. Objects
placed on the folded second-row middle seat
may move freely during braking, vehicle
maneuvers, or an accident and be thrown
around in the vehicle interior. Objects thrown
around in the vehicle interior may cause an
accident and/or serious personal injury.XTo put the backrest into the armrest
