Opening and closing

against your seat belt by the unsecured driv-
er's seat.
This could cause you to lose control of the
vehicle. The seat belt cannot protect as inten-
ded and could result in additional injury.
There is a risk of an accident and injury.
Before every journey, make sure that the driv-
er's seat is fully engaged.
Observe the safety notes on "Air bags"
(
Ypage 44) and "Children in the vehicle"
(Ypage 53).
GWARNING

move unexpectedly while the vehicle is in
motion. This could cause you to lose control of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
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

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.
!To prevent damage to the seats and the seat
heating, observe the following notes:
RDo not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does get
spilled on the seats.

Where possible, use the seats only for car-
rying passengers.
RWhen operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
RWhen the seat heating is switched on, the
seat surface can be damaged as a result of objects being placed on the seats; for
exam ple, seat c
ushions, child seats and

dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

midification function (
Ypage 117).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 118).
Deactivate air-recirculation mode e
(
Ypage 121).
Set airflow control Ato a setting between 3
and 6(
