restraints. Head restraints are intended to
help reduce injuries during an accident.
! To avoid damage to the seats and the seat
heating, observe the following information:
Rdo not spill any liquids 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

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
passengers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. covers, bags, seat covers,
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.
iThe head restraints in the front seats are
installed with the NECK-PRO system
(Y page 52). For this reason, it is not
possible to remove the head restraints
from the front seats.
Vehicles without the through-loading
feature: the head restraints cannot be
removed from the rear compartment seats.

GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.
GWarning!
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise their protective function cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.
