!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 inte-
rior.
iResonance 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
Your vehicle may be equipped with a sliding
sunroof or a panorama roof with power tilt/
sliding panel. In this section, the term "sliding
sunroof" refers to both types of sliding sun-
roof.
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 of paying
attention when closing the sliding sunroof.
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
automatic closing process
The closing process is stopped.

for your attentiveness to the roller sunblind
while it is closing.
GWARNING
The reversing function does not react in par-
ticular to soft, light and thin objects, e.g. small
fingers. This means that the reversing feature
cannot prevent someone being trapped in
these situations. There is a risk of injury.
When closing the roller sunblind, make sure
that no body parts are in the sweep area.

Problems with the sliding sunroof
Your vehicle may be equipped with a sliding sunroof or a panorama roof with power tilt/sliding
panel. In this section, the term "sliding sunroof" refers to both types of sliding sunroof.
GWARNING
If you close the sliding sunroof again immediately after it has been blocked or reset, the sliding
sunroof closes with increased or maximum force. The reversing feature is then not active. Parts
of the body could be trapped in the closing area in the process. This poses an increased risk of
injury or even fatal injury.
Make sure that no parts of the body are in the closing area.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the automatic closing process
The closing process is stopped.
!If the sliding sunroof still cannot be opened or closed as a result of a malfunction, contact
a qualified specialist workshop.
ProblemPossible causes/consequences and MSolutions
The sliding sunroof can-
not be closed and you
cannot see the cause.If the sliding sunroof is obstructed during closing and reopens
again slightly:
XImmediately after the sliding sunroof blocks, pull the 3
switch in the overhead control panel down to the point of resist-
ance and hold it until the sliding sunroof is closed.
The sliding sunroof is closed with increased force.
If the sliding sunroof is obstructed again during closing and then
reopens slightly:
XImmediately after the sliding sunroof blocks, pull the 3
switch in the overhead control panel down to the point of resist-
ance and hold it until the sliding sunroof is closed.

Seats
Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The seats can still be adjusted when there is
no SmartKey in the ignition lock.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Observe the safety notes on "Air bags"
(
Ypage 54) and "Children in the Vehicle"
(
Ypage 68).
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
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 sys-
tem.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.

the headlamps varies due to legal require-
ments and self-imposed obligations.
If you wish to drive during the daytime without
lights, switch off the daytime running lamps
function in the on-board computer
(
