54Seats, restraintsCurtain 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 if a child restraint
system is to be fitted on this seat. The side airbag and curtain airbag
systems, the belt pretensioners and
all driver airbag systems will remain
active.The front passenger airbag system can be deactivated via a key-
operated switch on the right side of the instrument panel.
