Seat belts that are fastened correctly offer good protection in the event of an
accident. They reduce the risk of an injury and increase the chance of survival
in the event of a major accident.
Properly fastened seat belts hold occupants to correctly set seats in the right
seat position.
Particular safety aspects must be observed when transporting children in the
vehicle » page 19 .
WARNING■
Fasten your seat belt before each journey – even when driving in town!
This also applies to other passengers - there is a danger of injury!■
Maximum seat belt protection is only achieved if you are correctly seated
» page 8 , Correct and safe seated position .
■
The seat backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can lose their effectiveness.
WARNINGInformation on the correct routing of the belt■Always ensure that the webbing of the seat belts is properly routed. Seat
belts which are not correctly adjusted can themselves cause injuries even
in minor accidents.■
Adjust the height of the belt in such a way that the shoulder part of the
belt is roughly positioned across the middle of your shoulder – on no ac-
count across your neck.
WARNING (Continued)■ A seat belt which is hanging too loose can result in injuries as your body is
moved forward by the kinetic energy produced in an accident and is then
suddenly held firm by the belt.■
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, bunches of keys etc.). Such objects can cause injury.
WARNINGInformation on dealing with the safety belts■The belt webbing must not be jammed in-between at any point or twis-
ted, or chafe against any sharp edges.■
Make sure you do not catch the seat belt in the door when closing it.
WARNINGInformation on the proper use of the safety belts■No two persons (also not children) should ever use a single seat belt to-
gether.■
The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to
protect and the risk of injury increases.
■
The slot of the belt tongue must not be blocked, otherwise the belt
tongue will not lock in place properly.
■
Many layers of clothing and loose clothing (e. g. a winter coat over a jack-
et) do not allow you to be correctly seated and impairs proper operation of
the seat belts.
■
Do not use clamps or other objects to adjust seat belts (e.g. for shorten-
ing the belts for smaller persons).
■
The seat belts for the rear seats can only fulfil their function reliably
when the seat backrests are correctly locked into position » page 71.
WARNINGInformation on the care and maintenance of the safety belts■The belt webbing must always be kept clean. Dirty belt webbing may im-
pair the correct functioning of the inertia reel.■
The seat belts must not be removed or changed in any way. Do not at-
tempt to repair the seat belts yourself.
11Seat belts
The shoulder part of the seat belt must never run across the neck but must
roughly run over the middle of the shoulder and fit snugly against the chest.
The lap part of the belt must run across the pelvis, must not be positioned
across the stomach and must always fit snugly » Fig. 5 -
.
Seat belt height adjusters for front seats
The seat belt height adjuster makes it possible to adjust the routing of the
front seat belts in the area of the shoulder to the body size.›
Press the height adjuster and move to the desired position » Fig. 6.
›
Then pull firmly on the belt to ensure that the seat belt height adjuster has
correctly locked in place.
Seat belts with pregnant women
Expectant women must also always wear a seat belt. This is the only way of ensuring optimal protection for the unborn child.
With pregnant women, the lap part of the belt must be positioned as low as
possible on the pelvis to avoid exerting any pressure on the lower abdomen
» Fig. 5 -
.
Fastening and unfastening seat belts
Fig. 7
Fastening/unfastening the seat belt
Read and observe
on page 11 first.
Before using the seat belts the following conditions must be met. Correctly set head restraint (not for seats with integrated head restraint).
Correctly adjusted seat (applies for the front seats).
Correctly adjusted steering wheel (applies to the Driver's seat ).
Fasten›Use the lock tongue to slowly pull the webbing over your chest and pelvis.›
Insert the lock tongue into the belt buckle for the seat » Fig. 7 -
until it
audibly clicks into place.
›
Pull on the belt to check that it has engaged correctly in the lock.
Release
Release the seat belt only when the vehicle is stationary.
›
Press the red button in the belt buckle » Fig. 7 -
; the lock tongue pops out.
›
Manually guide the belt back so that it is easier to fully roll up the webbing,
the seat belt does not twist.
CAUTION
When releasing the seatbelt ensure that the tongue of the lock does not dam-
age the door trim or other parts of the interior.
Inertia reels and belt tensioners
Introduction
This chapter contains information on the following subjects:
Inertia reels
13
Belt tensioners
13
Inertia reels
Each seat belt is equipped with an inertia reel. When pulling slowly on the seat
belt, the belt can move freely.
When pulling sharply on the seat belt, the movement is locked by the inertia
reel. The belts also lock when full braking, when the car accelerates, when
driving downhill and when cornering.
WARNINGIf the seat belt does not lock when pulling sharply on it, have it inspected
immediately by a specialist garage.
Belt tensioners
Safety for the driver and front passenger wearing their seat belts is enhanced
by the belt tensioners fitted to the inertia reels of the front three-point seat
belts.

System descriptionRead and observe
on page 14 first.
The inflation of the airbag is carried out in a fraction of a second.
When the airbags are deployed, they fill with gas and inflate.
A grey white or red, non-harmful gas is released when the airbag is inflated.
This is perfectly normal and is not an indication of a fire in the vehicle.
Depending on the vehicle equipment, the airbag system consists of the
following parts. ▶ Front airbag for the driver and the front passenger » page 15.
▶ Side airbags » page 16.
▶ Head airbags » page 17.
▶ Airbag warning light in the instrument cluster » page 34.
▶ Key switch for the front passenger airbag » page 18.
▶ Warning light for the front passenger airbag in the middle of the dash panel
» page 18 .
Airbag deployment
Read and observe
on page 14 first.
The airbag system is only functional when the ignition is switched on.
Triggering conditions
It is not possible to generally determine which deployment conditions apply to
the airbag system in every situation. An important role is played by factors
such as the type of object that the vehicle hits (hard/soft), the impact angle, vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration which
occurs. If the vehicle deceleration which occurs and is measured during the
collision remains below the prescribed reference values specified in the control
unit, the airbags are not deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident.
The following airbags will be deployed in the event of a severe frontal
collision.
▶ Driver’s front airbag.
▶ Front passenger airbag.
The following airbags will be deployed in the event of a severe side collision.
▶ Front side airbag on the side of the accident.
▶ Head airbags on the side of the accident.
When an airbag is deployed, the following events occur.
▶ The interior light comes on (if the automatic operation of the interior light is
switched on - switch
).
▶ The hazard warning lights are switched on.
▶ All the doors are unlocked.
▶ The fuel supply to the engine is interrupted.
When there is no air bag deployment?
With minor frontal and side collisions, rear collision, overturning of the vehicle
or vehicle roll-over there is no airbag deployment.

ference from transmitters close to the car and which operate in the same fre-
quency range (e.g. mobile phone, TV transmitter).■
The operating range of the remote control key is approx. 30 m. But this range
of the remote control can be reduced if the batteries are weak.
■
The battery must be replaced if the central locking does react to the remote
control at less than around 3 metres away » page 167.
Note
The remote control will operate only when visual contact with the vehicle.
