If one or more of the lamps on the seat ven-
tilation button are flashing, there is insufficient
voltage available since too many electrical con-
sumers are turned on. The seat ventilation
switches off automatically.
The seat ventilation will switch back on again au-
tomatically as soon as sufficient voltage is avail-
able.
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so 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 po-
tential for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
i
Adjust the head restraint in such a way that
it is as close to the head as possible.
