Seat belts
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 po-
sitions and substantially reduce the kinetic energy in the event of an acci-
dent. Seat belts also help to prevent uncontrolled movements that could
lead to severe injuries. In addition, properly worn seat belts reduce the dan-
ger 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 ab-
sorb the kinetic energy released in a collision. Taken together, all these fea-
tures reduce the releasing kinetic energy and consequently, the risk of in-
jury.
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 seri-
ous 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 fas-
tened 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 pas-
sengers have fastened their seat belts properly before you drive off!

WARNING
● If the seat belts are worn incorrectly or not at all, the risk of severe
injuries increases. The optimal protection from seat belts can be ach-
ieved only if you use them properly.
● Fasten your seat belt before every trip - even when driving in town.
The other passengers must also wear the seat belts at all times, other-
wise they run the risk of being injured.
● The seat belt cannot offer its full protection if the seat belt is not
positioned correctly.
● Never allow two passengers (even children) to share the same seat
belt.
● Keep both feet in the footwell in front of your seat as long as the vehi-
cle is in motion.
● Never unbuckle a seat belt while the vehicle is in motion. Risk of fatal
injury.
● The seat belt must never be twisted while it is being worn.
● The seat belt 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 al-
ter the position of the belt webbing.WARNING (Continued)
● Frayed or torn seat belts or damage to the connections, belt retrac-
tors or parts of the buckle could cause severe injuries in the event of an
accident. Therefore, you must check the condition of all seat belts at reg-
ular intervals.
● Seat belts which have been worn in an accident and stretched must
be replaced by a specialised 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.

Seat belt adjustment
The seat belts for the front and rear occupants are locked in-
to position by a latch.
Fig. 11 Belt buckle and
latch plate of seat belt
The seat belt cannot offer its full protection if the seat belt is not
positioned correctly.
– 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
⇒ 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 ten-
sioners ⇒ 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 in-
creased.
● If an occupant is incorrectly belted in, the belt cannot protect him or
her properly. An incorrectly positioned seat belt can cause extremely se-
vere injuries.

Airbag system
The danger of fitting a child seat on the front passenger
seat
Rear-facing child seats must never be used on the front pas-
senger 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 transported 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 41. 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 disconnect the
airbag, the vehicle must be taken to a Technical Service.
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 in-
creases.
● 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 in-
juries if the front passenger airbag is triggered.
WARNING (Continued)
● 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 back-
rest.
● 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 es-
sential that you observe the following safety measures:
–Deactivate the front passenger airbag ⇒ page 41, 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 po-
sition.

WARNING
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger airbag has been disabled. This could
lead to a risk of potentially fatal injuries to the child! However, if it is nec-
essary, in exceptional cases, to transport a child in the front passenger
seat, the front passenger airbag must always be disabled ⇒ page 41, De-
activating airbags*. If the passenger seat has a height adjustment op-
tion, move it to the highest position.
● For those vehicles that do not include a key lock switch to disconnect
the airbag, the vehicle must be taken to a Technical Service.
● All passengers, especially children, must assume the proper sitting
position and be properly belted in while travelling.
● Never hold children or babies on your lap, this can result in potential-
ly fatal injuries to the child!
● Never allow a child to be transported in a vehicle without being prop-
erly secured, or to stand up or kneel on a seat while travelling. In an acci-
dent, the child could be flung through the vehicle, causing possibly fatal
injuries to themselves and to the other passengers.
● If children assume an improper sitting position when the vehicle is
moving, they expose themselves to greater risk of injury in the event of a
sudden braking manoeuvre or in an accident. This is particularly impor-
tant if the child is travelling on the front passenger seat and the airbag
system is triggered in an accident; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave an unsupervised child alone on a child seat or in the vehi-
cle.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.WARNING (Continued)
● Children who are less than 1.5 metres tall must not wear a normal
seat belt without a child seat, as this could cause injuries to the abdomi-
nal and neck areas during a sudden braking manoeuvre or in an accident.
● Do not allow the seat belt to become twisted or jammed, or to rub on
any sharp edges.
● Incorrectly worn seat belts can cause injuries even in a minor colli-
sion or in sudden braking manoeuvres.
● The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒ page 25, Seat belts.
● Only one child may occupy a child seat ⇒ page 45, Child seats.

Securing child seats
Ways to secure a child seat
A child seat can be secured differently on the rear seat and
on the front passenger seat. You can secure a child seat to the rear seat or front passenger seat in the
following ways:
● Child seats in groups 0 to 3 can be secured with a seat belt.
● Child seats for groups 0, 0+ and 1 with the ISOFIX system can be se-
cured, without fastening seat belts, with the ISOFIX securing rings
⇒ page 48.

WARNING
● When travelling, children must be secured in the vehicle with a re-
straint system suitable for age, weight and size.
● Never install a child seat facing backwards on the front passenger
seat unless the front passenger airbag has been disabled. This could
cause fatal injuries to the child! However, if, in exceptional cases, it is
necessary to transport a child in the front passenger seat, the front pas-
senger airbag ⇒ page 41, Deactivating airbags* must always be disabled
and the seat adjusted to its highest position, where possible.
● Read and always observe information and warnings concerning the
use of child seats ⇒ 
in Safety notes on using child seats on page 44.
Securing a child seat with the ISOFIX system
Child seats can be secured quickly, easily and safely on the
rear outer seats with the ISOFIX system.
Fig. 26 ISOFIX securing
rings 

Child safety
When removing or fitting the child seat, please be sure to follow
the manufacturer's instructions.
– Press the child seat onto the ISOFIX retaining rings until the
child seat can be heard to engage securely. If the child seat is
fitted with any other anti-rotation system, follow the manufac-
turer instructions carefully.
– Pull on both sides of the child seat to ensure that it is secure.
Two ISOFIX retaining rings are fitted on each rear seat. In some vehicles, the
rings are secured to the seat frame and, in others, they are secured to the
rear floor. The access to the ISOFIX rings is between the rear seat backrest
and the seat cushioning.
Child seats with ISOFIX mountings are available in your Authorised Service
Centres.
WARNING
● The retaining rings are designed to only be used with ISOFIX child
seats.
● Never secure child seats without the ISOFIX system, retaining belts or
objects to the fastening rings – this can result in potentially fatal injuries
to the child.
● Ensure that the child seat is secured correctly to the ISOFIX anchor
points.
 Top Tether retainer straps
Some child restraint seats have a third Top Tether anchoring
point, apart from both ISOFIX anchoring points, which allow
better child retention.
Fig. 27 Position of the
Top Tether rings on the
back of the rear seat
Child seats with the Top Tether system come with a strap for securing the
seat to the vehicle anchor point, located at the back of the rear backrest.
The retainer strap is used to reduce forwards movements of the safety seat
in a crash, helping reduce the risk of injuries to the head from hitting the
inside of the vehicle.
It is foreseen that an EU Directive will introduce requirements related to the
retention of child restraint systems by means of ISOFIX and Top Tether an-
chorages (probably compulsory for new types from 2010), which will entail
improved retention of the child restraint seat and less head movement in
case of frontal collisions. 
