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 in the front and three in the rear. Each seat is
equipped with a three-point seat belt. In some versions, your vehicle is approved
only for four seats. Two front seats
and two rear seats.
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.

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, in
the case of a head-on collision all of their 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
head-on collision, they will move forward at the same speed their vehicle was

Seat 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 vehicle.
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, overturns 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 section.
– Ensure that the seat belts can be fastened at all times and are not damaged.
WARNING
•If the seat belts are worn incorrectly or not at all, the risk of severe inju-
ries increases. The optimal protection from seat belts can be achieved only
if you use them properly.

– Adjust the seat and head restraint correctly.
– To fasten the belt, take hold of the latch plate and pull it slowly
across your chest and lap.
– Insert the latch plate into the buckle for the appropriate seat and push it down until it is securely locked with an audible click
⇒page 24, fig. 11 .
– Pull the belt to ensure that the latch plate is securely engaged in the buckle.The seat belts are equipped with an automatic retractor on the shoulder
strap. Full freedom of movement is permitted when the shoulder belt is pulled
slowly. However, during sudden braking, during travel in steep areas or
bends and during acceleration, the automatic retractor on the shoulder belt
is locked.
The automatic belt retractors on the front seats are fitted with seat belt
tensioners ⇒page 28.
WARNING
•An incorrectly worn seat belt can cause severe injuries in the event of
an accident.•The seat belts offer best protection only when the backrests are in an
upright position and the seat belts have been fastened properly.•Never put the latch plate in the buckle of another seat. If you do this, the
seat belt will not protect you properly and the risk of injury is increased.•I f a n o ccu p an t is i n co r re c t l y be l te d i n , t h e b e l t ca n n o t p ro te c t h i m o r h e r
properly. An incorrectly positioned seat belt can cause extremely severe
injuries.•Always engage the retractor lock when you are securing a child seat in
group 0, 0+ or 1 ⇒page 46.
Seat belt position
Seat belts offer their maximum protection only when they are
properly positioned.

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 seat belt tensioner is not reduced and that
removed parts do not cause any injuries or environmental pollution, regula-
tions, which are known to the specialised workshops, must be observed.
WARNING
•Improper use or repairs not carried out by qualified mechanics increase
the risk of severe or fatal injuries. 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 seat belt tensioner, seat belt and 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 specialised workshop only.•The belt tensioners will only provide protection for one accident and
must be changed if they have been activated.

•Always adjust the front seats properly.
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.The front passenger airbag is a serious risk for a child if it is activated. The
front passenger seat is life threatening to a child if he/she is transpor ted in a
rear-facing child seat. Children up to 12 years old should always travel 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 force that it can cause critical or fatal injuries.
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 44.
When transporting children, use a child seat appropriate to the age and size
of each child ⇒ page 46.
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 if 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.•For those vehicles that do not include a key lock switch to turn the
airbag off, an Authorised Service Centre must be consulted.•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:
−Deactivate the front passenger airbag ⇒page 44, “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 given by the child seat manufac-
turer and observe the safety instructions ⇒page 46, “Child safety”.
− 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.
