The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the head in the event of a
side-on impact considerably.

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.

The front passenger airbag system must be deactivated for child restraint
system on the passenger seat
according to the instructions in the
table 3 67. 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 passenger side of the instrument panel.
Use the key blade, located in theelectronic key, to choose the position:
*
OFF:front passenger airbag is
deactivated and will not
inflate in the event of a
collision. Control indicator

continuously in the centre
consoleV
ON:front passenger airbag is
active
64Seats, restraints9Danger
Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 67.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
If the control indicator V 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.
