Seats, restraints39Using the seat belt while pregnant9Warning
The lap belt must be positioned as
low as possible across the pelvis
to prevent pressure on the
abdomen.
Airbag system
The airbag system consists of a
number of individual systems
depending on the scope of
equipment.
When triggered, the airbags inflate
within milliseconds. They also deflate
so quickly that it is often unnoticeable
during the collision.9 Warning
If handled improperly the airbag
systems can be triggered in an
explosive manner.
Notice
The airbag systems and belt
pretensioner control electronics are
located in the centre console area.
Do not put any magnetic objects in
this area.
Do not affix any objects onto the
airbag covers and do not cover them with other materials.
Each airbag is triggered only once.
Have deployed airbags replaced by
a workshop. Furthermore, it may be
necessary to have the steering
wheel, the instrument panel, parts of
the panelling, the door seals,
handles and the seats replaced.
Do not make any modifications to
the airbag system as this will
invalidate the vehicle type approval.
When the airbags inflate escaping hot gases may cause burns.
Fault
If there is a fault in the airbag system, the control indicator v illuminates and
a message or a warning code
appears in the Driver Information
Centre. The system is not
operational.
Have the cause of the fault remedied by a workshop.

Page 45 of 239

Seats, restraints43Fit 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.
The location is 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.
Notice
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. The location is 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.
Page 46 of 239

44Seats, restraints9Warning
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 47. The side airbag and
curtain airbag systems, the belt
pretensioners and all driver airbag
systems will remain active.Use the ignition key to choose the
switch position:
* 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 47.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.

46Seats, restraintsSuitable are restraint systems that
comply with valid UN ECE
regulations. Check local laws and
regulations for mandatory use of child restraint systems.
Ensure that the child restraint system to be installed is compatible with the
vehicle type.
Ensure that the mounting location of
the child restraint system within the
vehicle is correct, see following
tables.
Allow children to enter and exit the
vehicle only on the side facing away
from the traffic.
When the child restraint system is not in use, secure the seat with a seat beltor remove it from the vehicle.
Notice
Do not affix anything on the child
restraint systems and do not cover
them with any other materials.
A child restraint system which has
been subjected to stress in an
accident must be replaced.
