Opening and closing

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.
Do not rotate the head restraints of the front and
rear seats. Otherwise, you cannot adjust the
height and angle of the head restraints to the
correct position.
Using the fore-and-aft adjustment, adjust the
head restraint so that it is as close as possible to
your head.
G WARNING
You could lose control of your vehicle if you do
the following while driving: R
adjust the driver's seat, head restraint,
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 mirror 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 sys-
tem.
G WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury. Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
! To avoid damage to the seats and the seat
heating, observe the following information: R
keep liquids from spilling 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 heat-
ing should also not be used to dry the seats. R
clean the seat covers as recommended;
see "Interior care". 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 passen-
gers, if possible. R
when the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.

Problems with the seat heating/ventilation Problem
Possible causes/consequences and P Solutions
The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation can be switched back on manually.114
