for the respective front seat.
The LED in the button illuminates to
indicate activation.
Pressing ß once more deactivates
seat heating.

During an Autostop, seat heating is
also operational.
Stop-start system 3 136.Seat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle holding the occupants in
the sitting position. Therefore the risk
of injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 50.
Periodically check all parts of the belt
system for damage, pollution and
proper functionality.
Have damaged components
replaced. After an accident, have the
belts and triggered belt pretensioners replaced by a workshop.
Note
Make sure that the belts are not
damaged by shoes or sharp-edged
objects or trapped. Prevent dirt from
getting into the belt retractors.
Seat belt reminder
Each seat is equipped with a seat belt
reminder, indicated for driver seat as
control indicator X in the tachometer
3 91, and for front passenger seat
as control indicator k in the centre
console 3 88.
For rear seats, the seat belt reminder is indicated by symbols X in the Driver
Information Centre 3 97.

42Seats, restraintsBelt force limitersOn the front seats and the rear
outboard seats, stress on the body is
reduced by the gradual release of the belt during a collision.
Belt pretensioners In the event of a head-on or rear-end
collision of a certain severity, the front
seat belts are tightened.9 Warning
Incorrect handling (e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
Deployment of the belt pretensioners
is indicated by continuous illumination
of control indicator v 3 91.
Triggered belt pretensioners must be replaced by a workshop. Belt
pretensioners can only be triggered
once.
Note
Do not affix or install accessories or
other objects that may interfere with
the operation of the belt
pretensioners. Do not make any
modifications to belt pretensioner components as this will invalidate
the vehicle type approval.
Three-point seat belt
Fasten
Withdraw the belt from the retractor,
guide it untwisted across the body
and insert the latch plate into the
buckle. Tighten the lap belt regularly
while driving by pulling the shoulder
belt.
Sport seat: Feed seat belt through
belt mount on backrest when
fastening seat belt.
Loose or bulky clothing prevents the
belt from fitting snugly. Do not place
objects such as handbags or mobile
phones between the belt and your body.
9 Warning
The belt must not rest against hard
or fragile objects in the pockets of
your clothing.

1. Pull belt out slightly.
2. Shift the height adjuster upwards or press button to disengage and
push the height adjuster
downwards.

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.
Note
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.

48Seats, restraintsThe 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 37.
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.
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.
Note
Only use protective seat covers that
have been approved for the vehicle.Be careful not to cover the airbags.

Seats, restraints49Curtain 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.
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.
Airbag deactivation
The front passenger airbag system must be deactivated for a child
restraint system on the passenger
seat according to the instructions in
the tables 3 52.
The other 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 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
active

Seats, restraints519Danger
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 52.
Airbag deactivation 3 49.
Airbag label 3 44.
The rear seats are the most
convenient location to fasten a child restraint system.
Children should travel facing
rearwards in the vehicle as long as
possible. This ensures that the child's backbone, which is still very weak, is
under less strain in the event of an
accident.
Selecting the right system Only use suitable restraint systems,
e.g. those that comply with valid
UN ECE regulations.
Ensure that the child restraint system to be installed is compatible with the
vehicle type. Refer to the tables on
the following pages, the instructions
supplied with the child restraint
system and the vehicle type list of
non-universal child restraint systems.
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.
Child restraint systems could be
fastened with ISOFIX mounting
brackets, Top-tether if available,
and/or a three-point seat belt. Refer
to the following tables.
Note
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.
