– Press the upper part of the shoulder belt guide and hold it in this position ⇒page 27, fig. 16.
– Move the shoulder belt guide up or down until you have adjusted the seat belt ⇒page 25.
– After adjusting, pull the shoulder belt sharply to check that the catch on the shoulder belt guide is engaged securely.Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe injuries.Seat belts can provide optimal protection only if the belt web is
properly worn. The seat belts must be fastened exactly in the order
described in this chapter. An incorrect sitting position impairs
substantially the protection a seat belt offers and can lead to severe
or fatal injuries. The risk of severe or fatal injuries is especially
increased when a deploying airbag strikes an occupant who has
assumed an incorrect sitting position . As driver, you are responsible
for all vehicle occupants, especially children. Therefore:
– Never permit anyone to assume an incorrect sitting position in the vehicle while travelling ⇒.
WARNING
•
An incorrectly worn seat belt incr eases the risk of severe injuries.
•
Before every trip, instruct your passengers to adjust their seat belts
properly and to wear them during the trip.
•
Read and always observe information and warnings concerning the use
of seat belts ⇒ page 23.
Belt tension devicesFunction of the belt tension device
During a frontal collision, the se at belts on the front seats are
retracted automatically.The seat belts for the front occupants are equipped with belt tension devices.
Sensors will only trigger the belt te nsion devices during severe head-on,
lateral and rear collisions, and only if th e seat belt is actually being worn. This
retracts and tightens the seat belts, reducing the forward motion of the occu-
pants.
The belt tension device ca n be triggered only once.
The belt tension devices will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns, or in situations where no large
forces act on the front, side or rear of the vehicle.
Note
•
If the belt tension devices are triggered, a fine dust is produced. This is
normal and is no indication that there was a fire in the vehicle.
•
The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. A qualified workshop is familiar with
these regulations and will be pleased to pass on the information to you.
Service and disposal of belt tension devicesThe belt tension devices are components of the seat belts that are installed
in the seats of your vehicle. If you work on the belt tension devices or remove
and install parts of the system when performing other repair work, the seat

Airbag system
38Side airbagsDescription of side airbags
The airbag system is not a substitute for the seat belts.The side airbags are located in the driver seat and front passenger seat back-
rests ⇒fig. 21 . The locations are identified by the text “AIRBAG” in the upper
region of the backrests.
In conjunction with the seat belts, the side airbag system gives the front seat
occupants additional protection for the upper body in the event of a severe
side collision ⇒page 41, “Safety notes on the operation of the side airbag
system”.
In a side collision the side airbags reduce the risk of injury to passengers on
the front seats to the areas of the body facing the impact. In addition to their
normal function of protecting the occupants in a collision, the seat belts also
hold the passengers on the front seats in a position where the side airbags
can provide maximum protection. The airbag system is not a substitute for
seat belts, but is an integral part of
the vehicle's overall passive safety system. Please bear in mind that the
airbag system can only work effectively when the occupants are wearing their
seat belts. For this reason, it is most important to wear the seat belts at all
times - not only because this is required by law in most countries, but also for
your safety ⇒page 19, “Introduction”.
The side airbag system will not be triggered
•
if the ignition is switched off,
•
during a minor side collision,
•
during a minor frontal collision,
•
during a minor rear-end collision,
•
or if the vehicle rolls.
The main parts of the airbag system are
•
an electronic control and monitoring system (control unit),
•
the side airbags in the sides of the backrests of the front seats,
•
a warning lamp
 in the dash panel insert ⇒ page 31.
The functionality of the airbag system is monitored electronically. The airbag
warning lamp will light up for approx. 4 seconds every time the ignition is
switched on (self-diagnosis).
WARNING
•
In a side-on collision, the side airb ags will not work, if the sensors do
not correctly measure the pressure incr ease on the interior of the doors,
due to air escaping through the areas wi th holes or openings in the door
panel.
•
Never drive the vehicle if the interior panels have been removed.
•
Never drive if the interior door panels have been removed or if the
panels have not been correctly fitted.

risk of injury in side impact collisions.
WARNING
•
If you do not wear a seat belt, if you lean forward, or are not seated
correctly while the vehicle is in motion , you are at greater risk of injury
should the side airbag system be triggered in an accident.
•
In order for the side airbags to provide their maximum protection, the
prescribed sitting position must alwa ys be maintained with seat belt
fasten while travelling.
•
Occupants of the outer seats must never carry any objects or pets in the
deployment space between them and th e airbags, or allow children or
other passengers to travel in this position. It is also important not to attach
any accessories (such as cup holders) to the doors. This would impair the
protection offered by the side airbags.
•
The built-in coat hooks should be used only for lightweight clothing. Do
not leave any heavy or sharp-edged objects in the pockets.
•
Great forces, such as hard blows or kicks, must not be exerted upon the
backrest bolster because the system may be damaged. In this case the side
airbags would not be triggered.
•
Under no circumstances should protective covers be fitted over the
driver seat or front passenger seat unless the covers have been expressly
approved for use in your vehicle. Because the airbag deploys from the side
of the backrest, the use of non-approved seat covers would obstruct the
side airbag seriously reducing the airbag's effectiveness ⇒page 186,
“Accessories, parts replacement and modifications”.
•
Any damage to the original seat uphol stery or around the seams of the
side airbag units must be repaired immediately by a qualified workshop.
•
The airbags provide protection for one accident only, if they have been
deployed they must be replaced.
•
When children assume an incorrect sitting position, they expose them-
selves to an increased risk of injury in the event of an accident. This is
particularly the case if the child is travelling on the front passenger seat
and the airbag system is triggered in an accident; this could have critical
consequences including serious injury or death ⇒page 47, “Child safety”.
•
Any work on the side airbag system or removal and installation of the
airbag components for other repairs (such as removal of the front seat)
should only be performed by a qualif ied workshop. Otherwise, a fault may
be introduced into the operation of the airbag system.
•
Do not attempt to modify components of the airbag system in any way.
•
The side and head airbags are managed through sensors located in the
interior of the front doors. To ensure the correct functioning of the side and
head airbags neither the doors nor the door panels should be modified in
any way (e.g. fitting loudspeakers). If the front door is damaged in any way,
this may affect the correct working of the system. All work carried out on
the front door must be made in a qualified workshop.WARNING (continued)

There must be no other persons, animals or objects between the occu-
pants of the outer seats and the deployment space of the curtain airbags
so that the curtain airbag can deploy without restriction and provide the
greatest possible protection. Therefore, sun blinds which have not been
expressly approved for use in your vehicle may not be attached to the side
windows ⇒ page 186, “Accessories, parts replacement and modifica-
tions”.
•
The built-in coat hooks should be used only for lightweight clothing. Do
not leave any heavy or sharp-edged objects in the pockets. When using the
coat hooks, do not hang the clothes on coat hangers.
•
The airbags provide protection for one accident only, if they have been
deployed they must be replaced.
•
Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lining)
should only be performed by a qualified workshop. Otherwise, a fault may
be introduced into the operation of the airbag system.
•
Do not attempt to modify components of the airbag system in any way.
