WARNING
Modifications to electroni ccomponents, their
software as wellasw iring couldaffect their
function and/or the operation of other net-
worked components. This coul dinparticular
alsobet he case for systems relevant to
safety .They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as wellas
electronic components or their software.
Always have work on electrica land electronic
components carrie dout at aqualified special-
ist workshop.
If you make any changes to the vehicl eelec-
tronics, the genera loperating permi tisren-
dered invalid.
! There is
arisk of damage to the vehicl eif:
R the vehicl ebecome sstuck, e.g. on ahigh
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or apothol einthe road
R ah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body ,the under-
body ,chassi sparts, wheels or tyres coul dbe
damaged without the damage being visible.
Components damaged in this way can unex-
pectedl yfail or, in the case of an accident, no
longer withstand the strain they are designed
for.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust system, they can catch fire.
In such situations, have the vehicl echecked
and repaired immediatel yataqualified spe-
cialist workshop. If, uponc ontinuing your
journey ,you notice that driving safety is
impaired ,pullo ver and stop the vehicl eimme-
diately ,paying attention to road and traffic
conditions. In such cases, consult aqualified
specialist workshop. Declarations of conformity

Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. Furthermore, the restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system The various components of the restraint system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 42)
R have correctly adjusted their seat and head
restraint (Y page 102).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 102).
Additionally, you must ensure that an airbag can
deploy freely (Y page 44).
The airbag is supplementary to acorrectly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If
the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore, in the event of an accident, only airbags which
provide greater protection in the given accident
situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 52).
See "Children in the vehicle" for information on
infantsa nd children traveling with you in the
vehicle restraint systems for infantsa nd chil-
dren(Y page 55). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If modification of an airbag system is necessary to accommodate aperson with disabilities, con-
tact aqualified specialist workshop for details. Occupant safety

Seat belts
Introduction Ac
orrectly fastened seat belt is the most effec-
tive means of restraining the movement of vehi- cle occupants in the event of an accident or
overturn .This reduces the risk of vehicle occu-
pants coming into contact with parts of the vehi-
cle interior or being thrown from the vehicle. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag deployed.
The seat belt system consistso f:
R Seat belts
R Belt tensioners and belt force limiters
If the seat belt is pulled quickly or suddenly from the belt sash guide, the inertia reel locks. The
belt strap cannot be pulled out further.
The belt tensioner tightenst he seat belt to lie
close against your body in the event of acolli-
sion. However, it does not pull the vehicle occu-
pants back towards the seat backrest.
The belt tensioner also does not correct an
incorrec tseat position or the strap layoutofa
seat belt that is worn incorrectly.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced.
The belt force limiters on the front seats are
synchronised with the front airbags, which take
on apart of the deceleration force. This makes it
possible to reduce the forces to which vehicle
occupants are subjected during an accident.
! If the co-driver's seat is not occupied, do not
engage the seat belt tongue in the buckle on
the co-driver's seat. Otherwise, the belt ten-
sioner could be triggered in the event of an
accident and would have to be replaced.
Important safety notes G
WARNING
The seat belt cannot perform its intended pro- tective function if it is not fastened correctly. Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal. Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly.
G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtallc annot wear the
seat belts correctl ywithou tas uitable, addi-
tional restraint system. The seat belt cannot
perform its intende dprotective functio nifitis
not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
rie sint he event of an accident, sudden brak-
ing or abrupt change sofdirection. There is an
