56Seats, restraintsThe side airbag system consists of anairbag in each front seat backrest.
This can be identified by the word
AIRBAG .
The side airbag system is triggered in
the event of a side 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 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.

Seats, restraints57Airbag 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
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
consoleÓ 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 61.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
If the control indicator ÓON
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 *OFF
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.

58Seats, restraintsConsult 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. Control indicator for airbag
deactivation 3 91.Child restraints
Child restraint systems9 Danger
If using a rear-facing child restraint
system on the front passenger
seat, the airbag system for the
front passenger seat must be
deactivated. This also applies to certain forward-facing child
restraint systems as indicated in
the tables 3 61.
Airbag deactivation 3 57.
Airbag label 3 52.
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 anchor
Three-point seat belt
Child restraint systems can be
fastened by using a three-point seat
belt.
