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, occupant
s of the car not wearing a seat belt, are
thrown forward and strike in an uncontrolled
way parts of the interior of the car, such
as steering wheel, da
sh panel, windscreen,
⇒page 141, fig. 133
. The occupants 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 143.
•
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 138, “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 of the front seats must not be tilted too far to the rear
otherwise the seatbelts 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 199, “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. 134 Routing of belt webbing for an expect
ant mother / routing of belt webbing over the
shoulders and the lap belt– Correctly adjust the front seat and the head
restraint before fastening your seat belt
⇒ page 72.
– 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. It also
blocks the belts when the car accelerates,
when driving uphill 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. 134
on the right. 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. 134
on the left.
•
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 adjusterThe seat belt height adjuster makes it possible for you to adapt the routing of the three-point seat belt in the area of the shoulder to match your body size. – Move the height adjuster in the desired direction up or down
⇒fig. 135

of the lock to jump out.
– Guide the belt back with your hand to en
able the inertia reel to wind up the belt
webbing more easily.
A plastic knob in the belt webbing holds the be
lt tongue in a position which is easy to
get hold of.Three-point seat belt for the rear middle seat The three-point seat belt for the rear middle seat is anchored in the area of the luggage compartment on the left side of the headliner.Your car is equipped as standard
with the three-point seat belt.
Fastening the seat belt– Pull the belt with both lock to
ngues out of the headliner mount.
– Insert the lock tongue at the end of the belt
into the seat belt buckle on the left side
until it is heard to lock in place.
– Pull the second lock tongue, which is move
able on the seat belt, over the chest and
insert it into the belt buckle on the right side until it is heard to lock in place.
– Pull on the belt to check that both lock
tongues are reliably engaged in the locks.
– The belt tongues for the rear middle seat are shaped differently so that they only fit
into the respective belt buckle. If you attempt to insert a lock tongue into the wrong belt lock it will not lock.
Taking seat belt off– Take off the seat belt in the reverse order to fastening.
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 74.
•
After releasing the seat belt hold it tight and let it slowly reel up until both
lock tongues lock into the headliner mount and are secured with a magnet - risk of injury.•
Never release simultaneously both tongues of the lock.
Belt tensionersSafety 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, in addition
to the protection afforded
by the airbag system.
The three-point seat belts are automatically te
nsioned in the event of a frontal collision
of a certain severity. The belt tensioners can
also be deployed if the seat belts are not
fastened.

Technical Data
When are the airbags deployed?The airbag system is designed in such a wa
y that the driver and front passenger airbag
are deployed in the event of a
violent frontal collision
.
In the case of a
violent side collision
, the side airbag* on the side of the vehicle at
which the collision occurs, is deployed to
gether with the relevant head airbag*.
In special cases, the front as well as th
e relevant side and head airbags may be
deployed together. The airbags
are not deployed
in the case of
minor
frontal and side collisions, in the
case of rear-end collisi
ons 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 is pl
ayed by factors such as the type of object
against which the vehicle impacts (hard, soft
), the angle of impact, the relative speed
during the accident 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, 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.
•
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; − the fuel supply to the engine is interrupted.
Front airbagsDescription of the front airbags The airbag system is not a su
bstitute for the seat belt!

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
⇒page 148.
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

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 forward movement of the body is cushioned when it makes contact with the fully inflated airbag and the risk of injury to
the legs of the driv
er is thus reduced.

WARNING
•
The surface of the airbag module in the lower part of the dash panel below
the steering column 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 must be attached
to the cover of the airbag module or be
located within the immediate 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.
•
Do not attach any bulky and heavy obje
cts (keys etc.) to the keylock. These
can be ejected by the knee airb
ag being deployed and hurt you.
Side airbags*Description of side airbags The side airbag together with the head airbag offers enhanced occu- pant protection in the event of a side collision.The front side airbags are housed in the upho
lstery of the seat backrests of the front
seats
⇒fig. 141
.
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) of the occupants
of the vehicle in the event of severe side collisions
⇒page 151.
Apart from their normal protective function, a further task of the
seat belts
is to also
hold the occupents of the front or rear exteri
or seats in a correct seated position in the
event of a side collision so as to enable th
e side airbag to offer the maximum protec-
tion. You should therefore always fasten the seat belts, not only because this is required by law, but also for safety reasons and for your own protection. Each time the side airbags are deployed, th
e head airbag* and the front belt tensioner
on the side of the car on which the collision
occures, are automati
cally deployed at the
same time in order to provide the
occupant with enhanced protection.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you in maintaining control of
your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as
entering a curve fast. The risk of skidding
is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. The system operates at all speeds. The following systems are integrated into the electronic stability programme:•
electronic Differential Lock (EDL),
•
traction control system (TCS),
•
active driver-steering recommendation (DSR),
•
antilock brake system (ABS),
•
brake Assist,
•
uphill-Start off-Assist.
The ESP system cannot be switched off, the
TCS system can only be switched off by
pressing the button
⇒fig. 154
, then the ESP warning light flashes slowly
.
Operating principle The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also proc- esses additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehicle about its ve
rtical axis, the lateral acceleration of the
vehicle, the braking pressure and the steering angle. The direction which the driver wishes to take is determined based on the steering angle and the speed of the vehicle and is co
nstantly compared with the actual behav-
iour of the vehicle. If
differences exist, such as the vehi
cle beginning to skid, the ESP will
automatically brake the appropriate wheel. The car is stabilised again by the forces wh
ich take effect when the wheel is braked.
Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner rear wh
eel of a vehicle whic
h tends to understeer
(tendency to shift out of the curve). This braking control cycle is accompanied by noises. During an intervention of the system, the warning light
flashes quickly in the instru-
ment cluster
⇒page 35.
The ESP operates in combination with the ABS
⇒page 167, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light lights up in the inst
rument cluster when there is a fault on the
ESP
⇒page 35.WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the road surfac
e and the traffic situation. This partic-
ularly applies when driving on slippery
and wet roads. The increased safety
