The speed of the vehicle is,
nevertheless, the most important factor. Doubling the
speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four times. The common opinion that it is possible to su
pport your body in a minor accident with
your hands, is incorrect. Even in a collision at only a low speed, the forces acting on the body are such that it is no longer possible to support your body. Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body in
the event of an accident can easily exceed
10.000 N (Newton). This equals a weight of one tonne (1 000 kg). In the event of a frontal collision, occupants
of the vehicle not wearing a seat belt, are
thrown forward and strike in an uncontrolled
way parts of the interior of the vehicle,
such as steering wheel,
dash panel, windscreen,
page 117, fig. 110
- left. The occu-
pants of a vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can result in fatal injuries. It is also important that rear seat occupants fasten their seat belts as they will otherwise be thrown through the vehicle in an uncontr
olled manner in the event of an accident

Important safety information regarding the use of seat beltsThe correct use of the seat belts cons
iderably reduces the risk of injury!
WARNING
The belt webbing must no
t be jammed in-between at any point or twisted,
or chafe against any sharp edges.
It is important that the belt webbing is properly routed if the seat belts are
to offer their maximum protection
page 119, “How are seat belts correctly
fastened?”.
No two persons (also not children) should ever use a single seat belt
together.
The maximum protection which seat belts can offer is only achieved if you
are correctly seated
page 114, “Correct seated position”.
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, keys etc.) as this may be a cause of injuries.
Bulky, loose clothing (e.g. a winter coat over a jacket) does not allow you to
be correctly seated and impairs proper operation of the seat belts.
It is prohibited to use clamps or other objects to adjust seat belts (e.g. for
shortening the belts for smaller persons).
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 seat backrests must not be tilted too far to the rear otherwise the seat-
belts can lose their effectiveness.
The belt webbing must always be ke
pt clean. Soiled belt webbing may
impair proper operation of the inertia reel
page 161, “Seat belts”.
The slot of the belt tongue must not be blocked by paper or similar objects
otherwise the belt tongue will not lock in place properly.
Inspect the seat belts regula
rly to ensure they are in
good condition. If you
find seat belts which have damage to the seat belt webbing, seat belt connec- tions, to the inertia reels or to the lock,
the relevant safety belt must be replaced
by a specialist garage.
The seat belts must not be removed or changed in any way. Do not make an
attempt to repair the seat belts yourself.
Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a specialist garage. The anchorage points of the
belts must also be inspected. The
anchorage points for the belts should also be checked.
In certain countries it is possible to use seat belts which differ in terms of
their operation from the seat belts wh
ich are described on the pages which
follow.

Fig. 111 Routing of belt webbing over the sh
oulders and the lap belt / Routing of belt
webbing for an expectant mother– Correctly adjust the seat and the head restraint before fastening your seat belt
page 114, “Correct seated position”.
– Slowly pull the belt webbing at the tongue
of the lock over your chest and pelvis
.
– Insert the tongue of the lock into the seat belt buckle belonging to the seat until it
is heard to lock in place.
– Pull on the belt to check that it has also reliably engaged in the lock. Each three-point seat belt is equipped with
an inertia reel. This inertia reel offers you
complete freedom of movement if the belt is unreeled slowly. If the brakes are applied suddenly, the inertia reel will block. The
belts also block when the car accelerates,
when driving downhill and when cornering. Expectant mothers must also wear the seat belt
.
WARNING
The shoulder part of the seat belt must never run across your neck but must
run approximately over the middle of the shoulder and fit snugly against the
chest. The lap part of the belt must r
un across the hip and must never be routed
across the stomach. It must always fit snugly
fig. 111
- left. Adjust the belt
webbing as required.
The lap part of the belt should be posi
tioned as low as possible at the pelvis
of an expectant mother in order to avoid exerting any pressure on the lower abdomen
fig. 111
- right.
Always ensure that the webbing of the
seat belts is properly routed. Seat
belts which are not correctl
y adjusted can themselves cause injuries even in
minor accidents.
A seat belt which is hanging too loose can result in injuries as your body is
moved forward by the kinetic energy pr
oduced in an accident and is then
suddenly held firm by the belt.
Only insert the lock tongue into the lock which is the correct one for your
seat. This will affect the protection which
the belt offers and increase the risk of
an injury.Seat belt height adjuster on the front seatsThe seat belt height adjuster makes it possible for you to adapt the routing of the front three-point seat belt in the area of the shoulder to match your body size. – To adjust the belt height press the heig

get hold of.
Three-point safety belt for the middle rear seatIt is used in the same way as the normal three-point seat belts on the left and right (at front and rear). The three-point seat belt fo
r the rear middle seat must be put on first
to allow the pelvic part of the belt to run
between the belt lock for the right three-point
seat belt and the backrest, while avoiding
crossing the belt webbi
ng of the right and
middle seat belts.
WARNING
The three-point safety belt for the rear middle seat can only fulfil its func-
tion reliably when the backrests are correctly locked into position
page 61.
Note
The vehicles of the category
N1 are not equipped with the third seat belt on the rear
seats. The vehicle is only approved for four persons.Belt tensionerSafety 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. The fastened three-point seat belts are automatically tensioned in the event of a frontal or side collision of a certain severity. The belts tensioners are also deployed if the seat belts are not fastened. Belt tensioners are not activated in the even
t of minor frontal collisions, side and rear-
end collisions, in the case of a rollover an
d also not in accident
s in which no major
forces are produced from the front.
WARNING
Any work on the belt tigh
tener system, including removal and installation of
system components because of other repair work, must only be carried out by a specialist garage.

Airbag system
122
Airbag systemDescription of the airbag systemGeneral information on the airbag systemThe front airbag system is complementary to
the three-point seat belts and offers addi-
tional protection for the head and chest area of the driver and passenger in the event of a frontal collision. In the event of a side collision, the side airb
ags reduce the risk of injury to the occu-
pants to the part of their body
facing the side of the accident.
The airbag system is only functional af
ter the ignition has been switched on.
The operational readiness of the airbag syst
em is monitored electronically. The airbag
indicator light comes on for a few seconds
each time the igniti
on is switched on.
The airbag system (according to vehicle equipment) consists of:
an electronic control unit;
the front airbags for the driver and front passenger
page 123;
the side airbags
page 125;
head airbags
page 127;
an airbag indicator light
in the instrument cluster
page 33;
a front passenger airbag switch*
page 129;
an indicator light for a switched off fron
t seat passenger airbag* in the middle of
the dash panel
page 129.
A fault in the airbag system exists if:
the airbag indicator light does not light up when the ignition is switched on;
the airbag indicator light does not go out
after about 3 seconds after the ignition is
switched on;
the airbag indicator light goes out and come
s on again after the ignition is switched
on;
the airbag indicator
light comes on or flickers when driving;
an airbag indicator light showing a switched-off front passenger airbag* in the
middle of the dash panel flashes.
WARNING
To enable the occupants of a vehicle
to be protected with the greatest
possible effect when the airbag is
deployed, the front seats must be
page 114, “Correct seated position” correctly adjusted to match the body size of the occupant.
If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, you are exposing yourself to increased risk of injury in the event of an accident.
Have the airbag system checked immediat
ely by a specialist garage if a fault
exists. Otherwise, there is a
risk of the airbag not bein
g activated in the event of
an accident.
No modifications of any kind may be made to parts of the airbag system.
It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.
The protective function of the airbag system is sufficient for only one acci-
dent. The airbag system must then be re
placed if the airbag has been deployed.
The airbag system needs no main
tenance during its working life.
If you sell your car, please hand over the complete vehicle documentation to
the new owener. Please note that the documents relating to the possibility of deactivating the front passenger airbag are also part of the vehicle documents!
If the vehicle or individual parts of
the airbag system are scrapped, it is
essential to observe the relevant safety
precautions. Specialist garages are
familiar with these regulations.
When disposing of vehicle or parts of the airbag system, it is important to
comply with the national legal requirements.

Technical Data
When are the airbags deployed?The airbag system is designed in such a
way that the driver and the front passenger
airbag* are deployed in the event of a
frontal collision of major severity
.
In the case of a
violent side crash
, the side airbag* in the front seat and the head
airbag* on the side on which the collision occurs are deployed. It is also possible under certain special accident situations that the front as well as the side airbags and head airbags* are deployed at the same time. The airbags
are not deployed
in the case of
minor
frontal and side collisions, rear-end
collisions, tilting of the ve
hicle and vehicle rollover.
Deployment factors It is not possible to state globally which
deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary greatly. An important role in this case, for ex
ample, is played by factors such as the type
of object against which the vehicle impacts (h
ard, soft), the angle of impact, the vehicle
speed etc. A decisive factor for the deployment of the airbags is the deceleration which occurs during a collision. The control unit analyses
the nature of the collision and activates the
relevant restraint system. 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 no
t deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident. The airbags are not deployed if:
ignition is switched off;
a minor frontal collision;
a minor side collision;
a rear-end collision;
Rollover of the vehicle.Note
A grey white or red, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indi
cation of a fire in the vehicle.
In the event of an accident in which the airbags are deployed: the interior lighting comes on (if the swit
ch for the interior light is in the door
contact position), the hazard warning li
ght is switched on;
All the doors are unlocked.
Front airbagsDescription of the front airbags The airbag system is not a su
bstitute for the seat belt!
Fig. 114 Driver airbag in the steering wheel
/ front passenger airbag in the dash panel
The front airbag for the driver is housed in the steering wheel
fig. 114
- left. The front
airbag for the front passenger* is housed in the dash panel above the storage compart- ment
fig. 114
- right. The installation positions are each marked with the “AIRBAG”
logo. The front airbag system, in combination with
three-point safety belts, offers additional
protection for the head and chest area of the driver and front passenger in the event of a frontal collision of major severity
in “Important safety information regarding
the front airbag system” on page 124. The airbag is not a substitute for the seat
belt, but is part of the complete passive
vehicle safety concept.
Please note that an airbag can only offer you optimal
protection in combination with a seat belt which is fastened
.

Apart from their normal protective function, a further task of the
seat belts
is to also
hold the driver and front passenger in a correct seated position in the event of a frontal collision so as to enable the front ai
rbags to offer the maximum protection.
You should therefore always fasten the seat be
lts, not only because this is required by
law, but also for safety reasons and for your own protection
page 117, “Why seat
belts?”.
Caution
The dash panel must be replaced after the front passenger airbag has been deployed.Function of the front airbags Risk of injury to the upper part of the body is reduced by fully inflated side airbags.The airbag system is designed in such a way that the driver and front passenger airbag* are deployed in the event of a frontal collision of major severity. In certain accident situations, the front, side and head airbag are simultaneously deployed. If the airbags are deployed, the airbags are filled with a propellant gas and inflated in front of the driver and front passenger
fig. 115
. The airbags inflate in fractions of a
second and at a high speed in order to be able
to offer that additional protection in the
event of an accident. The movement of the
driver and of the front passenger is cush-
ioned when they make contact with the fully
inflated airbag and the risk of injury to
head and chest is thus reduced. The specially developed airbag allows the gas
to flow out of the inflated airbag in a
controlled manner (depending on the load of
the particular car occupant) in order to
cushion head and chest areas. The airbag then
deflates subsequently to such an extent,
after an accident, to again provide a clear view forward. A grey white, non harmful gas is released when airbag is inflated. This is perfectly normal and is not an indicati
on of a fire in the vehicle.
The airbag develops enormous forces when triggered, which can lead to injuries if the sitting position or seated position is not correct
in “Important safety information
regarding the front airbag system”.Important safety information regarding the front airbag system Correct use of the airbag system cons
iderably reduces the risk of injury!
WARNING
Never transport children on the front seat of a vehicle without using a
proper restraint system. If airbags are de
ployed in the event of an accident, the
child might suffer severe
or even fatal injuries!
For the driver and front passenger it is important to maintain a distance of
at least 25 cm from the steering wheel or dash panel
fig. 116
. Not main-
taining this minimum distance will mean that the airbag system will not be able to properly protect you - hazard! The front seats and the head restraints must always also be correctly adjusted to match the body size of the occupant.

It is essential to always switch off
page 128, “Deactivating airbags” the
front passenger airbag when attaching a child safety seat on the front passenger seat where the child is seated
with its back facing in direction of
travel (in some countries also
when the child is facing the direction of travel). If
this is not done, there is a risk of the ch
ild suffering severe or even fatal injuries
if the front passenger airbag is deploy
ed. In certain countries national legal
provisions also require that the side or
head passenger airbags be deactivated.
When transporting a child on the front passenger seat, please comply with the appropriate national regu
lations regarding the use of child safety seats.
There must not by any further persons, animals or objects positioned
between the front seated occupants and
the deployment area of the airbag.
The steering wheel and the surface of th
e airbag module in the dash panel
on the passenger side must not be stuck
onto, covered or modified in any other
way. These parts should only be cleaned with a dry cloth or a cloth moistened with water. No objects such as cup holders, mobile phone mounts, etc. may be attached to the covers of the airbag modules or be located within the imme- diate area.
No modifications of any kind may be
made to parts of the airbag system.
Any work on the airbag system includ
ing installing and removing system
components because of other repair wo
rk (e.g. removing the steering wheel)
must only be carried out by a specialist garage.
Never carry out changes on the front bumper or on the body.
Never place any objects on the surface of the dash panel on the front

Side airbags*Description of side airbags The side airbag increases protection
of the passenger concerned in the
case of a side impact.The side airbags are housed in the upholstery of the seat backrests of the front seats and are marked with the lettering “AIRBAG”

on the middle part.
The side airbag system in combination with the three-point seat belts, offers additional protection for the upper area of the body
(chest, stomach and pelvis) in the event of
severe side collisions
in “Important safety information on the side airbag” on
page 126. Apart from their normal protective function, a further task of the
seat belts
is to also
