Seats, restraints399Warning
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 44. 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 in the glovebox.

continuously in the centre console.ON Ó:front passenger airbag is
active.9 Danger
Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 44.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
If the control indicator Ó illuminates
for approx. 60 seconds after the
ignition is switched on, the front
passenger airbag system will inflate
in the event of a collision.
If the control indicator * illuminates
after the ignition is switched on, the front passenger airbag system is
deactivated. It stays on while the
airbag is deactivated.
If both control indicators are
illuminated at the same time, there is
a system failure. The status of the
system is not discernible, therefore
no person is allowed to occupy the
front passenger seat. Contact a
workshop immediately.
Consult a workshop immediately if
neither of the two control indicators
are illuminated.
Change status only when the vehicle is stopped with the ignition off.
Status remains until the next change.
