!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif 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.
Rclean the seat covers as recommended;
see the "Interior care" section.
Rdo 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.
Rwhen 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.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
RPosition the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
RYour arms should be slightly bent when you
are holding the steering wheel.
RAvoid seat positions that prevent the seat belt
from being correctly routed. The shoulder
section of the belt must be routed over the
middle of your shoulder and be pulled tight
against your upper body. The lap belt must
always pass across your lap as low down as
possible, i.e. over your hip joints.
RAdjust the head restraint so that it supports
the back of the head at eye level.
RThe distance from the pedals should be such
that you can depress them fully.
Please also observe the important safety notes
on "Air bags" (
Ypage 50), "Seat belts"
(Ypage 47) and "Child restraint systems"
(Ypage 59).

Seat heating
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to high temperatures may be
affected or they may even suffer burn-like
injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
!When you leave your seat, do not place any-
thing on the seat and switch off the seat heat-
ing. Do not switch the seat heating on when
the seat is not occupied, e.g. when driving
without a front passenger. The seat heating
may otherwise overheat, causing damage to
the seat.
The three red indicator lamps in the Íbutton
show the activated heating level 1to 3.
The seat heating automatically switches down
from level 3to level 2after approximately seven
minutes.
The system automatically switches down from
level 2to level 1after approximately ten
minutes.
At level 1the seat heating switches off auto-
matically after approximately 20 minutes.
XMake sure that the key is in position 1or 2in
the ignition lock.
XTo switch on: press theÍbutton repeat-
edly until the desired heating level has been
set.
XTo switch off: press theÍbutton repeat-
edly until all indicator lamps go out.
If the on-board voltage is too low, the seat heat-
ing will either switch itself off prematurely or not
come on at all. In this case, too many electrical
consumers are switched on or the battery
charge is not sufficient. The seat heating will
automatically switch back to the current heating level when enough on-board voltage is available
again.
