Important safety notes
G
Risk of injury
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
Risk of accident
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
Risk of injury
Make sure that nobody can become trapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
Risk of injury
Make sure that the back of your head is sup-
ported at eye level by the central area of the
head restraint .Ifyour head is not supported
correctly by the head restraint, you could suf-
fer a severe neck injury in the event of an
accident .Never drive if the head restraints are
not engaged and set correctly. G
Risk of injury
Occupants should only travel sitting on seats
which have the head restraints fitted. On a
seat which is occupied, move the head
restraint into the upright position .This
reduces the risk of injury to the passenger in
the event of an accident. !
To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids 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
heating should also not to be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
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
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 41). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
