Why wear seat belts?Physical principles of frontal collisions
In the event of a frontal collision, a large amount of kinetic
energy must be absorbed.
It is easy to explain how the laws of physics work in the case of a head-on
collision: When a vehicle starts moving ⇒fig. 6, a certain amount of energy
known as “kinetic energy” is produced in the vehicle and its occupants.
The amount of “kinetic energy” depends on the speed of the vehicle and the
weight of the vehicle and its passengers. The higher the speed and the
greater the weight, the more energy there is to be “released” in an accident.
The most significant factor, however, is the speed of the vehicle. If the speed
doubles from 25 km/h to 50 km/h, for example, the kinetic energy is multi-
plied by four.
Because the passengers in our example are not restrained by seat belts, all
of the passengers' kinetic energy has to be absorbed at the point of impact
⇒ fig. 7.
Even at speeds of 30 km/h to 50 km/h, the forces acting on bodies in a colli-
sion can easily exceed one tonne (1000 kg). At greater speed these forces are
even higher.
Passengers not wearing seat belts are not “attached” to the vehicle. In a
frontal collision, they will move forward at the same speed their vehicle was

travelling just before the impact. This example applies not only to frontal acci-
dents, but to all accidents and collisions.
The danger of not using the seat belt
The general belief that the passengers can protect them-
selves with their hands in a minor collision is false.
Even at low speeds the forces acting on the body in a collision are so great
that it is not possible to brace oneself with one's hands. In a frontal collision,
unbelted passengers are thrown forward and will make violent contact with
the steering wheel, dash panel, windscreen or whatever else is in the way
⇒
fig. 8 .
The airbag system is not a substitute for seat belts. When triggered, airbags
provide only additional protection. All passengers (including the driver) must
wear seat belts properly during the trip. This will reduce the risk of severe
injuries in the event of an accident – regardless of whether an airbag is fitted
for the seat or not.
Note that airbags can be triggered only once. To achieve the best possible
protection, the seat belt must always be worn properly so that you will be
protected in accidents in which no airbag is deployed.
It is also important for the rear passengers to wear seat belts properly, as they
could otherwise be thrown forward violently in an accident. Rear passengers
who do not use seat belts endanger not only themselves but also the front
occupants ⇒fig. 9 .

20Seat belt protection
Passengers not wearing seat belts risk severe injuries in the
event of an accident.Properly worn seat belts hold the vehicle occupants in the correct sitting posi-
tions and substantially reduce the kinetic energy in the event of an accident.
Seat belts also help to prevent uncontrolled movements that could lead to
severe injuries. In addition, properly worn seat belts reduce the danger of
being thrown from the car.
Passengers wearing their seat belts correctly benefit greatly from the ability
of the belts to absorb kinetic energy. The front part of your vehicle and other
passive safety features (such as the airbag system) are also designed to
absorb the kinetic energy released in a collision. Taken together, all these
features reduce the releasing kinetic energy and consequently, the risk of
injury.
Our examples describe frontal collisions. Of course, properly worn seat belts
substantially reduce the risk of injury in all other types of accidents. This is why it is so important to fasten seat belts before every trip, even when "just
driving around the corner".
Ensure that your passengers wear their seat belts as well. Accident statistics
have shown that wearing seat belts is an effective means of substantially
reducing the risk of injury and improving the chances of survival in a serious
accident. Furthermore, properly worn seat belts improve the protection
provided by airbags in the event of an accident. For this reason, wearing a
seat belt is required by law in most countries.
Although your vehicle is equipped with airbags, the seat belts must be
fastened and worn. The front airbags, for example, are only triggered in some
frontal accidents. The front airbags will not be triggered during minor frontal
collisions, minor side collisions, rear collisions, rolls or accidents in which the
airbag trigger threshold value in the control unit is not exceeded.
Therefore, you should always wear your seat belt and ensure that your
passengers have fastened their seat belts properly before you drive off!

WARNING
Never unbuckle a seat belt while the vehicle is in motion. If you do, you
increase the risk of sustaining severe or fatal injuries.
Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe or even mortal
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 in correct 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 the driver, you are respon-
sible for all vehicle occupants, especially children. Therefore:
– Never allow anyone to wear the seat belt incorrectly while the vehicle is moving ⇒.
WARNING
•An incorrectly worn seat belt increases the risk of severe injuries.•Before every trip, instruct your passengers to adjust their seat belts
properly and to wear them for the whole journey.•Read and always observe information and warnings concerning the use
of seat belts ⇒page 20.

Belt tensioners*Function of the belt tension device
During a frontal collision, the seat belts on the front seats are
retracted automatically.The seat belts for the front occupants are equipped with belt tensioners.
Sensors will trigger the belt tensioners during severe head-on, lateral and
rear collisions only if the seat belt is being worn. This retracts and tightens the
seat belts, reducing the forward motion of the occupants.
The belt tension device can be triggered only once.
The belt tensioners will not be triggered in the event of light frontal and side
collisions, 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 tensioners are triggered, a fine dust is produced. This is normal
and it is not an indication of 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 tensionersThe belt tensioners are components of the seat belts that are installed in the
seats of your vehicle. If you work on the belt tensioners or remove and install
parts of the system when performing other repair work, the seat belt may be
damaged. The consequence may be that, in the event of an accident, the belt
tensioners function incorrectly or not at all. So that the effectiveness of the belt tension device is not reduced and that
removed parts do not cause any injuries or environmental pollution, regula-
tions, which are known to the qualified workshops, must be observed.
WARNING
•If repairs are not carried out by a professional, or if the belt tensioners
are used incorrectly, the risk of severe or fatal injuries increases. The belt
tensioners may fail to trigger or may trigger in the wrong circumstances.•Never attempt to repair, adjust, remove or install parts of the belt
tensioners or seat belts.•The belt tension device and seat belt including its automatic retractor
cannot be repaired.•Any work on the belt tensioners and seat belts, including the removal
and refitting of system parts in conjunction with other repair work, must be
performed by a qualified workshop only.•The belt tensioners will only provide protection for one accident and
must be changed it they have been activated.

Airbag system
26Airbag systemBrief introductionWhy wear a seat belt and assume the correct sitting position?
For the inflating airbags to achieve the best protection, the
seat belt must always be worn properly and the correct sitting
position must be assumed.For your own safety and the safety of the passengers, please ensure
the following before driving:
– Always wear the seat belt properly
– Adjust the driver seat and the steering wheel correctly.
– Adjust the front passenger seat correctly.
– Adjust the head restraint correctly ⇒page 12.
– Use an appropiate child restraint system to protect children in your vehicle.The airbag is deployed at high speed in fractions of a second. If you have an
incorrect seating position at the time the airbag is deployed, it could cause
you critical injuries. Therefore, it is essential that all passengers in the vehicle
assume a correct sitting position while travelling.
A sharp braking before an accident may cause a passenger not wearing a seat
belt to be thrown forward into the area of the deploying airbag. In this case, the inflating airbag may inflict critical or fatal injuries on the occupant. This
also applies to children.
Always maintain the greatest possible distance between yourself and the
front airbag. This way, the front airbags can completely deploy when trig-
gered, providing their maximum protection.
The most important factors that will trigger an airbag are: the type of acci-
dent, the angle of collision and the speed of the vehicle.
Whether the airbags are triggered depends primarily on the vehicle deceler-
ation rate resulting from the collision and detected by the control unit. If the
vehicle deceleration occurring during the collision and measured by the
control unit remains below the specified reference values, the front, side
and/or curtain airbag will not be triggered. Take into account that the visible
damage in a vehicle involved in an accident, for whatever reason, is not an
indication as to why the airbags had been triggered.
WARNING
•Wearing the seat belt incorrectly or assuming an incorrect sitting posi-
tion can lead to critical or fatal injuries.•All occupants, including children, who are not properly belted can
sustain cr it ical or fatal inju ries if t he airbag is triggered. You s hould al ways
transport all children up to 12 years of age on the rear seat. Never transport
children in the vehicle if they are not restrained or the restraint system is
not appropriate for their age, size or weight.•I f yo u are n o t w ea r i ng a s ea t b e l t , i f yo u l e an fo r w a rd o r t o t h e s id e w h il e
travelling or assume an incorrect sitting position, there is a substantially
increased risk of injury. This increased risk of injury will be further
increased if you are struck by an inflating airbag.•To reduce the risk of injury from an inflating airbag, always wear the
seat belt properly.

•Always properly adjust the front seats.
The danger of fitting a child seat on the front passenger seat
Rear-facing child seats must never be used on the front
passenger seat when the front passenger airbag is enabled.An enabled front airbag on the front passenger side is potentially a major
danger to a child. The front passenger seat is life threatening to a child if
he/she is transported in a rear-facing child seat. You should always transport
all children up to 12 years of age on the rear seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such great force that critical or fatal injuries may
result.
Therefore we strongly recommend you to transport children on the rear seats.
That is the safest place for children in the vehicle. Alternatively, the front
passenger airbag can be disabled with a key-operated switch ⇒page 36.
When transporting children, use a child seat appropriate to the age and size
of each child.
For those vehicles that do not include a key lock switch to turn the airbag off,
an Authorised Service Centre must be consulted.
WARNING
•If a child seat is secured to the front passenger seat, the risk to the child
of sustaining critical or fatal injuries in the event of an accident increases.•Never secure a rear-facing child seat to the front passenger seat if the
front passenger airbag is enabled. The child can suffer critical or fatal inju-
ries when the front passenger airbag is triggered.
•An inflating front passenger airbag can strike the rear-facing child seat
and hurl it with great force against the door, the roof or the backrest.•If, under special circumstances, it is necessary to transport a child in a
rear-facing child seat on the front passenger seat, it is absolutely essential
that you observe the following safety measures:
−Disable the front passenger airbag ⇒page 36, “Deactivating
airbags*”.
− The child seat must be approved by the child seat manufacturer for
use on a front passenger seat with front or side airbag.
− Follow the installation instructions of the child seat manufacturer
and absolutely observe all warnings
− Before properly installing the child seat, push the front passenger
seat completely backwards so that the greatest possible distance to
the front passenger airbag is ensured.
− Ensure that no objects prevent the front passenger seat from being
pushed completely back.
− The backrest of the front passenger seat must be in an upright
position.
