In this section you will find important information, tips and notes on the sub-
ject of passive safety in your vehicle.
We have combined everything here which you should be familiar with, for ex-
ample, regarding seat belts, airbags, child seats and safety of children.
WARNING■ This chapter contains important information on how to use the vehicle for
the driver and his occupants.■
You will find further information on safety, which concerns you and those
travelling with you, in the following chapters of this Owner's Manual.
■
The complete on-board literature should always be in the vehicle. This
applies in particular, if you rent out or sell the vehicle.
Before setting off
Read and observe
on page 8 first.
For your own safety and the safety of the people travelling with you, please
pay attention to the following points before setting off.
Ensure that the lighting and the turn signal system are functioning proper-
ly.
Ensure that the function of the wipers and the condition of the wiper
blades are free of any defects.
Ensure that all of the windows offer good visibility to the outside.
Adjust the rear-view mirror so that vision to the rear is guaranteed.
Ensure that the mirrors are not covered.
Check the tyre inflation pressure.
Check the engine oil, brake fluid and coolant level.
Secure all items of luggage.
Do not exceed the permissible axle loads and permissible gross weight of
the vehicle.
Close all doors as well as the bonnet and boot lid.
Ensure that no objects can obstruct the pedals.
Protect children in suitable child seats with correctly fastened seat
belts » page 22 , Transporting children safely .
Adopt the correct seated position » page 9, Correct and safe seated
position . Tell your passengers to assume the correct seated position.
Driving safety
Read and observe
on page 8 first.
The driver is fully responsible for himself and his occupants. If your driving
safety is effected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. Do not get distracted from concentrating on the traffic situation, e.g. by
your passengers or mobile phone calls.
Never drive when your driving ability is impaired, e.g. through medication,
alcohol or drugs.
Keep to the traffic regulations and the permissible speed limit.
Always adjust the driving speed to the road, traffic and weather condi-
tions.
Take regular breaks on long journeys – at least every two hours.
Safety equipment
Read and observe
on page 8 first.
The following list contains only part of the safety equipment in your vehicle.
› Three-point seat belts for all the seats.
› Belt force limiters for the front seats.
› Belt tensioners for the front seats.
› Seat belt height adjusters for front seats.
› Front airbag for the driver and the front passenger.
› Driver’s knee airbag.
› Front side airbags.
› Rear side airbags.
8Safety
WARNING (Continued)■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.
■
It is prohibited to use clamps or other objects to adjust seat belts (e. g. for
shortening 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 92.
WARNINGInformation on the care and maintenance of the safety belts■The belt webbing must always be kept clean. Soiled belt webbing may im-
pair proper operation of the inertia reel » page 187.■
The seat belts must not be removed or changed in any way. Do not at-
tempt to repair the seat belts yourself.
■
Check the condition of all the seat belts on a regular basis. If any damage
to the seat belts, seat belt connections, inertia reel or the lock is detected,
the relevant seat belt must be replaced by a specialist garage.
■
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 for the belts should also be
checked.
Note
The national legal requirements must be observed when using seat belts.The physical principle of a head-on collisionFig. 4
Driver without a fastened seat belt/rear seat passenger without a
fastened seat belt
Read and observe
on page 12 first.
As soon as the vehicle is moving, so-called kinetic energy (the energy of mo-
tion) is produced both in terms of the car as well as in terms of the occupants.
The magnitude of this kinetic energy depends essentially on the speed at
which the vehicle is travelling and on the weight of the vehicle including the
occupants. The greater the speed and weight increase, the greater the
amount of energy which has to be absorbed in the event of an accident.
The speed of the vehicle is 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 opinion that it is possible to support your body in a minor accident with
your hands, is incorrect. Even in a collision at only a low speed, the forces act-
ing on the body are such that it is no longer possible to support your body.
Even if you only drive at a speed of 30 km/h to 50 km/h, the forces that your
body is exposed to in the event of an accident can exceed a metric ton
(1000 kg).
For example, a person's weight of 80 kg “increases” at 50 km/h to 4.8 tons
(4800 kg).
In the event of a frontal collision, occupants of the car not wearing a seat belt
are thrown forward and strike parts of the interior of the car, such as the
steering wheel, dash panel, windscreen in ways which cannot be control-
led » Fig. 4 -
. In certain circumstances you could even be thrown out of the
vehicle, which could cause life threatening or even fatal injuries.
