Seat 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.
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.

24•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 condition 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 207.

– 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 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 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 23.
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 th e 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

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 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 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 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.

Safety notes on using child seats
Proper use of child seats substantially reduces the risk of
injury in an accident!As the driver, you are responsible for any children you transport in
your vehicle.
– Protect your children by properly using appropriate child seats
⇒page 48.
– Always ensure that the belt webbing is properly positioned according to the instructions provided by the manufacturer of the
child seat.
– When travelling, do not allow children to distract you from traffic.
– Take breaks regularly during long trips. Take a break at least
every two hours.
WARNING
•Never install a child seat facing backwards (or rear-facing) 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
necessary, in exceptional cases, to transport a child in the front passenger
seat, the front passenger airbag must always be disabled ⇒page 44,
“Deactivating airbags*”. If the passenger seat has a height adjustment
option, move it to the highest position.•For those vehicles that do not include a key lock switch to turn the
airbag off, an Authorised Service Centre must be consulted.•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 potentially
fatal injuries to the child!•Never allow a child to be transported in a vehicle without being properly
secured, or to stand up or kneel on a seat while travelling. In an accident,
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 car is moving,
they expose themselves to greater risk of injury in the event of sudden
braking manoeuvre or in an accident. This is particularly important if the
child is travelling on the front passenger seat and the airbag system is trig-
gered 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
vehicle.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.•Children who are less than 1.5 metres tall must not wear a normal seat
belt without a child restraint system, as this could cause injuries to the
abdominal and neck areas during a sudden braking manoeuvre or in an
accident.•Do not allow the belt webbing to become twisted or jammed, or to rub
on any sharp edges.•Incorrectly worn seat belts can cause injuries even in a minor collision
or in sudden braking manoeuvres.•The seat belt provides maximum protection only when the belt web is
properly positioned ⇒page 24, “Seat belts”.•Only one child may occupy a child seat ⇒page 48, “Child seats”.WARNING (continued)

Securing child seatsWays 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.•Group 0, 0+ and 1 child seats with the “ISOFIX” system can be secured to
the “ISOFIX” retaining rings. In this case, seat belts are not necessary.
U: Suitable for universal approved restraining systems for use in this age category (universal retention systems are those fitted using the adult
seat belt).
*: Move the passenger seat as far to rear as possible, as high as possible and always deactivate the airbag.
L: Suitable for retention systems using the “ISOFIX” anchors
WARNING
•When travelling, children must be secured in the vehicle with a
restraint system suitable for age, weight and size.•Never install a child seat facing backwards (or rear-facing) on the front
passenger seat unless the front passenger airbag has been disabled. This
could cause fatal injuries to the child! However, if it is necessary, in excep-
tional cases, to transport a child in the front passenger seat, the front
passenger airbag must always be disabled ⇒page 44, “Deactivating
airbags*” and move the seat to its highest position, in case it has this
adjustment.•Read and always observe information and warnings concerning the use
of child seats ⇒ in “Safety notes on using child seats” on page 47.
