Seats, restraints63Airbag 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 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 ignition key to choose theposition:* OFF:front passenger airbag is
deactivated and will not
inflate in the event of a
collision. Control indicator
* OFF illuminates
continuously in the centre
consoleV ON:front passenger airbag is
active9 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 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 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.

We recommend a child restraint
system which is tailored specifically to
the vehicle. For further information,
contact your workshop.
When a child restraint system is being used, pay attention to the following
usage and installation instructions
and also those supplied with the child
restraint system.
Always comply with local or national
regulations. In some countries, the
use of child restraint systems is
forbidden on certain seats.
Child restraint systems can be
fastened with:
● Three-point seat belt
● ISOFIX brackets
● Top-tether
Three-point seat belt
Child restraint systems can be
fastened by using a three-point seat
belt. Depending on the size of the
used child restraint systems, up to
three child restraint systems can be
attached to the rear seats 3 67.
