Important safety notes
G
WARNING
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
WARNING
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 aresult of
the seat moving. This could cause an acci-
dent. G
WARNING
If you adjust the seat height carelessly,y ou or
others could be trapped and thereby injured.
Children in particular could unintentionally
press the buttons to electrically adjust the
seats and become trapped.

ported at eye level by the central area of the head restraint. If your head is not supported
correctly by the head restraint, you could suf-
fer asevere neck injury in the event of an
