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
1) if the driver has not fastened his/her seat belt, and a
warning signal is heard if the vehicle is driven at more than 30 km/h for 90
seconds.

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 .

•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.

position ⇒page 26, fig. 16 .
– 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

Airbag 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 ⇒page 19.
– Adjust the driver's seat and the steering wheel correctly ⇒page 10.
– Adjust the front passenger seat correctly ⇒page 11.
– Adjust the head restraint correctly ⇒page 13.
– Use the correct child restraint syst em to protect children in your
vehicle ⇒page 44.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 critical or fatal injuries if the airbag is triggered. You should always
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.•If you are not wearing a seat belt, if you lean forward or to the side while
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 ⇒page 19.

Monitoring of airbag and belt tension device system
Both the airbag and belt tension device systems operation is constantly
monitored electronically. Each time the ignition is switched on, the warning
lamp
 lights for several seconds and the display in the instrument panel*
shows AIRBAG / TENSIONER .
The system must be checked when the warning lamp
 :
•does not light up when the ignition is switched on,•after the ignition is switched on, it turns off after 4 seconds,•it turns off and then lights up again after the ignition is switched on,•lights up or flashes while the car is moving.
In the event of a malfunction, the warning lamp remains on continuously. In
addition, depending on the malfunction, a fault message appears in the
display of the combi-instrument for approx. 10 seconds and a short acoustic
sig nal is giv en . I n th is e ve nt, yo u s hould ha ve a q ua lif ie d wor ks hop che ck th e
system immediately.
If any of the airbags are de-activated by the Authorised Service Centre, the
indicator lights for several seconds more after the verification and will turn off
if there is no fault.WARNING
•If there is a malfunction, the airbag and belt tension device system
cannot properly perform its protective function.•If a malfunction occurred, have the system checked immediately by a
qualified workshop. Otherwise, in the event of an accident, the airbag
system and belt tension devices may not be triggered, or may not be trig-
gered correctly.
Repairs, maintenance and disposal of the airbagsThe parts of the airbag system are instal led in various places in your vehicle.
If you work on the airbag system or remove and fit parts of the system when
performing other repair work, parts of the airbag system may be damaged.
The consequence may be that, in the event of an accident, the airbag inflates
incorrectly or does not inflate at all.
The relevant safety requirements must be observed when the vehicle or
components of the airbag are scrapped. The specialist workshops and the
Vehicle disposal centres are familiar with these requirements.
WARNING
•If repairs are not carried out by a professional, or if the airbags are used
incorrect ly, th e ris k of se vere or fatal inj uries is increas ed. T he airbags may
fail to inflate, or could inflate in the wrong circumstances.•Do not cover or stick anything on the steering wheel hub or the soft
plastic surface of the airbag unit on the passenger side of the dashboard,
and do not obstruct or modify them in any way.•It is important not to attach any objects such as cup holders or tele-
phone mountings to the surfaces covering the airbag units.•To clean the steering wheel or dash panel, you may use only a dry or a
water-moistened cloth. Never clean the dash panel and the airbag module
surface with cleansers containing solvents. Solvents cause the surface to
become porous. If the airbag triggered, disintegrating plastic parts could
cause substantial injuries.•Never attempt to repair, adjust, remove or install parts of the airbag
system.•Any work on the airbag system or removal and installation of the airbag
components for other repairs (such as repairs to the steering wheel) should
be performed only by a qualified workshop. Qualified workshops have the
necessary tools, repair information and qualified personnel.

The main parts of the front airbag system are:
•an electronic control and monitoring system (control unit),•the two front airbags (airbag with gas generator) for the driver and front
passenger,•a warning lamp
 in the dash panel insert ⇒page 30.
The airbag system operation is monitored electronically. The airbag warning
lamp will light up for a few seconds every time the ignition is switched on
(self-diagnosis).
There is a fault in the system if the warning lamp

•does not light up when the ignition is switched on ⇒ page 30•after the ignition is switched on, it turns off after 4 seconds,•it turns off and then lights up again after the ignition is switched on,•lights up or flashes while the car is moving.
The front airbag system will not be triggered if:•the ignition is switched off,•there is a minor frontal collision,•there is a side collision,•there is a rear-end collision,•the vehicle turns over.WARNING
•The seat belts and airbags can only provide maximum protection if the
occupants are seated correctly ⇒page 10, “Proper sitting position for
occupants”.•If a fault has occurred in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise, during a frontal collision
the system may fail to trigger, or not trigger correctly.
Operation of frontal airbags
Inflated airbags reduce the risk of head or chest injury.The airbag system is designed so that the airbags for the driver and front
passenger are triggered in a severe frontal collision.
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbags fill with a propellant gas and
deploy in front of the driver and front passenger ⇒ fig. 19. The fully deployed
airbags cushion the forward movement of the front occupants and help to
reduce the risk of injury to the head and the upper part of the body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag. After the collision, the
airbag deflates sufficiently for the front occupants to see forward.
In order to provide the desired extra protection in an accident, the airbags
have to deploy extremely rapidly (within thousandth of a second). A fine dust
