The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the upper body and pelvis in
the event of a side-on collision
considerably.
9 Warning
Keep the area in which the airbag
inflates clear of obstructions.
Note
Only use protective seat covers that
have been approved for the vehicle.Be careful not to cover the airbags.
Curtain airbag system
The curtain airbag system consists of an airbag in the roof frame on each
side. This can be identified by the
word AIRBAG on the roof pillars.
The curtain airbag system is triggered
in the event of a side-on impact of a
certain severity. The ignition must be
switched on.
The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the head in the event of a
side-on impact considerably.
9 Warning
Keep the area in which the airbag
inflates clear of obstructions.
The hooks on the handles in the
roof frame are only suitable for
hanging up light articles of
clothing, without coat hangers. Do not keep any items in these
clothes.
Airbag deactivation
The front passenger airbag system must be deactivated for child restraint
system on the passenger seat
according to the instructions in the
table 3 61. The side airbag and
curtain airbag systems, the belt
