Seats, restraints55Front airbag systemThe front airbag system consists of
one airbag in the steering wheel and
one in the instrument panel on the
front passenger side. These can be
identified by the word AIRBAG.
Additionally, depending on vehicle,
there is a warning label on the side of
the instrument panel (visible when the
door is open), on the sun visor, or on
the lower part of the windscreen.
The front airbag system is triggered in
the event of an accident 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 head of
the front seat occupants
considerably.9 Warning
Optimum protection is only
provided when the seat is in the
proper position.
Seat position 3 42.
Keep the area in which the airbag
inflates clear of obstructions.
Fit the seat belt correctly and
engage securely. Only then is the
airbag able to protect.
Side airbag system
The side airbag system consists of an
airbag in each front seat backrest.
This may be identified by the word
AIRBAG .
The side airbag system is triggered in
the event of an accident 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.

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 may be identified by the
word AIRBAG on the headlining trim.
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.
Airbag deactivation
The front passenger airbag system
must be deactivated if a child restraint is to be fitted on the front passenger
seat in accordance with the
instructions in the Child restraint
installation locations tables 3 59.
The belt tensioners and all other
airbag systems will remain active.
The airbag deactivation system may
be indicated by a label on the side of
the instrument panel, visible when the
front passenger door is open.

be deactivated via a switch located on the side of the instrument panel.
Open the front passenger door to
access the switch.
Press the switch in and rotate to
choose the position:* OFF=front passenger seat airbag
system is deactivated and
will not inflate in the event of
a collision. Control indicator

a corresponding message
appears in the Driver
Information Centre 3 88.Ó ON=front passenger airbag
system is active.9 Danger
Risk of fatal injury for a child using
a child restraint system together
with activated front passenger
airbag.
Risk of fatal injury for an adult
person with deactivated front
passenger airbag.
If control indicator ÓON illuminates
after the ignition is switched on and
control indicator *OFF is not
illuminated, the front passenger
airbag system will inflate in the event
of a collision.
If both control indicators ÓON and
* OFF are illuminated
simultaneously, there is a system
failure. The status of the system is not discernible, therefore no person is
permitted to occupy the front
passenger seat. Contact a workshop immediately.
If control indicator F 3 84
illuminates together with v 3 83,
this indicates a fault within the
system. The switch position may have been changed inadvertently with the
ignition on. Turn ignition off and on
again and reset the switch position. If
F and v still remain illuminated, seek
the assistance of a workshop.
Change status only when the vehicle
