Seat beltsBrief IntroductionBefore driving: remember your seat belt!
Wearing a seat belt proper ly can save your life!In this chapter you will learn the importance of wearing seat belts,
how they work and how to properly fasten, adjust and wear them.
– Read and consider all the information as well as the warnings in
this chapter.
WARNING
•If seat belts are worn incorrectly or no t at all, the risk of severe injuries
increases.•Properly worn seat belts can reduce severe injuries in case of sudden
braking manoeuvres or accidents. For safety reasons, you and your passen-
gers must always wear the seat belts properly while the vehicle is moving.•P r e g n a n t w o m e n o r p e o p l e w i t h p h y s i c al d i s a b i l i t i e s m u s t a l s o u s e s e a t
belts. Like all other passengers, these people can also sustain severe inju-
ries if they are not wearing their seat belts properly.
Number of seatsYour vehicle has five seats, two on the front part and three on the rear part.
Each seat is equipped with a three-point seat belt.
WARNING
•More people than available seats must never be transported in your
vehicle.•Every passenger in the vehicle must properly fasten and wear the seat
belt belonging to his or her seat. Children must be protected with an appro-
priate child restraint system.
Seat belt warning lamp*

The warning lamp acts as a reminder to the driver to fasten
the seat belt.Before starting the vehicle:
– Fasten your safety belt securely.
– Instruct your passengers to fasten their seat belts properly before driving off.
– Protect children by using a child seat according to the child's height and weight.After the ignition has been switched on, the warning lamp  on the instru-
ment panel lights up

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 there is a certain amount of
energy known as “kinetic energy”, both in the vehicle and in the 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, the
entire amount of 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, dashboard, windscreen or whatever else is in the way
⇒
fig. 8 .
The airbag system is not a substitute for the 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 .

22Seat belts 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 properly that wearing seat belts is an effective mean of substan-
tially reducing the risk of injury and improving the chances of survival in a
serious accident. Furthermore, properly worn seat belts improve the protec-
tion 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!
Safety instructions
on using seat belts
If seat belts are used correctly, they can reduce the risk of
injury in an accident.– Always wear the seat belt as described in this booklet.
– Ensure that the seat belts can be fastened at all times and are not damaged.

•Fasten your seat belt before every trip - even when driving in town. The
other passengers must also wear the seat belt, otherwise they may be
danger of injury!•The seat belt cannot offer its full protection if the belt web is not posi-
tioned correctly.•Never allow two passengers (even children) to share the same seat belt.•Keep both feet in the foot-well in front of your seat as long as the
vehicle is in motion.•Never unbuckle a seat belt while the vehicle is in motion. Risk of fatal
injury.•The belt webbing must never be twisted while it is being worn.•The belt webbing should never lie on hard or fragile objects (such as
glasses or pens, etc.) because this can cause injuries.•Do not allow the seat belt to be damaged or jammed, or to rub on any
sharp edges.•Never wear the seat belt under the arm or in any other incorrect posi-
tion.•Loose, bulky clothing (such as an overcoat over a jacket) impairs the
proper fit and function of the belts, reducing their capacity to protect.•The slot in the seat belt buckle must not be blocked with paper or other
objects, as this can prevent the latch plate from engaging securely.•Never use seat belt clips, retaining rings or similar instruments to alter
the position of the belt webbing.•Frayed or torn seat belts or damage to the connections, belt retractors
or parts of the buckle could cause severe injuries in the event of an acci-
dent. Therefore, you must check the co ndition of all seat belts at regular
intervals.•Seat belts which have been worn in an accident and stretched must be
replaced by a qualified workshop. Renewal may be necessary even if there
is no apparent damage. The belt anchorage should also be checked.
•Do not attempt to repair a damaged seat belt yourself. The seat belts
must not be removed or modified in any way.•The belts must be kept clean, otherwise the retractors may not work
properly ⇒ page 205.

– Move the shoulder belt guide up or down until you have adjusted the seat belt ⇒ page 24.
– After adjusting, pull the shoulder belt sharply to check that the catch on the shoulder belt guide is engaged securely.Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe 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 incorrect 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 driver, you are responsible
for all vehicle occupants, especially children. Therefore:
– Never permit anyone to assume an incorrect sitting position in the vehicle while travelling ⇒.
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 during the trip.•Read and always observe information and warnings concerning the use
of seat belts ⇒page 22.
Belt tension devicesFunction 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 tension devices.
Sensors will only trigger the belt tension devices during severe head-on,
lateral and rear collisions, and only if the seat belt is actually being worn. This
retracts and tightens the seat belts, reducing the forward motion of the occu-
pants.
The belt tension device can be triggered only once.
The belt tension devices will not be triggered in the event of a light frontal,
side or rear collision, 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 tension devices 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 tension devicesThe belt tension devices are components of the seat belts that are installed
in the seats of your vehicle. If you work on the belt tension devices or remove
and install parts of the system when performing other repair work, the seat

28belt may be damaged. The consequence may be that, in the event of an acci-
dent, the belt tension devices 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 tension
devices are used incorrectly, the risk of severe or fatal injuries increases.
The belt tension devices may fail to trigger or may trigger in the wrong
circumstances.•Never attempt to repair, adjust, remove or install parts of the belt
tension devices or seat belts.•The belt tension device and seat belt including its automatic retractor
cannot be repaired.•Any work on the belt tension devices 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 tension devices will only provide protection for one accident
and must be changed it they have been activated.
