Safety
– Instruct your passengers to fasten their
seat belts properly before driving off.
– Protect children by using a child seat ac-
cording to the child's height and weight.
The control lamp  on the instrument panel
lights up 1)
if the driver's seat belt is not fas-
tened when the ignition is switched on.
If, when starting to drive, the speed surpass-
es 25 km/h (15 mph) approx. and no seat
belt is worn or it is unfastened during the
drive, a warning sound will be heard for a few
seconds. The warning light will also flash .
The  lamp goes out when the seat belt is
fastened with the ignition switched on. Seat belt protection Fig. 7
Drivers with properly worn seat belts
will not be thrown forward in the event of sud-
den braking Properly worn seat belts hold the occupants
in the proper position. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants 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 fea-
tures (such as the airbag system) are also de-
signed to absorb the kinetic energy released
in a collision. Taken together, all these fea-
tures reduce the releasing kinetic energy and
consequently, the risk of injury. This is why itis so important to fasten seat belts before ev-
ery 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 serious
injury and improving the chances of survival
when involved in an 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 air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!

Seat belts
Safety instructions on using seat
belts –
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 or fatal injuries in-
creases. The optimal protection from seat
belts can be achieved only if you use them
properly.
● Fasten your seat belt before every trip -
even when driving in town. The other vehicle
occupants must also wear the seat belts at all
times, otherwise they run the risk of being in-
jured.
● 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.
● Always keep both feet in the footwell in
front of your seat as long as the vehicle is in
motion.
● Never unbuckle a seat belt while the vehi-
cle 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 could cause injuries in the case
of an accident.
●
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 position.
● Loose, bulky clothing (such as an overcoat
over a jacket) impairs the proper fit and func-
tion of the seat 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 se-
curely.
● Never use seat belt clips, fastening rings or
similar items 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 accident. Therefore, you must
check the condition of all seat belts at regular
intervals.
● Seat belts which have been worn in an acci-
dent and stretched must be replaced by a
specialised workshop. Renewal may be nec-
essary 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 re-
moved or modified in any way.
● The belts must be kept clean, otherwise the
retractors may not work properly

called “kinetic energy” is created both in the
passengers and inside the vehicle.
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 “absorbed” in an
accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Because the vehicle occupants in our exam-
ple are not restrained by seat belts, in the
event of crashing against a wall, all of the oc-
cupants' kinetic energy will be absorbed
solely by said impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on the
body in a collision can easily exceed one
tonne (1000 kg). At greater speed these
forces are even higher.
Vehicle occupants 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 travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions. 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 con-
tact with the steering wheel, dash panel,
windscreen or whatever else is in the way
››› Fig. 8 .
It i
s also important for the rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-
danger not only themselves but also the front
occupants ››› Fig. 9. How t

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. 10
A.
● Pull the belt to ensure that the latch plate is
securely engaged in the buckle.
The seat belts are equipped with an automat-
ic retractor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing 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

. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up easily and the trim is not damaged.
Seat belt position
Seat belts offer their maximum protection on-
ly when they are properly positioned.
The following features are available to adjust
the seat belt in the shoulder region:
● belt height adjustment for the front seats.
● front seat height adjustment*. WARNING
● The seat belts offer best protection only
when the backrests are in an upright position
and the seat belts have been fastened prop-
erly.
● 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.
● Never unbuckle a seat belt while the vehi-
cle is in motion. If you do, you increase the
risk of sustaining severe or fatal injuries.
● An incorrectly worn seat belt can cause se-
vere injuries in the event of an accident.
● The shoulder part of the seat belt must lie
on the centre of the shoulder, never across
the neck. The seat belt must lie flat and snug-
ly on the torso ››› Fig. 11.
● The l ap p

art of the seat belt must lie across
the pelvis, never across the stomach. The
seat belt must lie flat and snugly on the pel-
vis ››› Fig. 11. Pull the belt tight if necessary
to t

ake up any slack.
● For pregnant women, the lap part of the
seat belt must lie as low as possible over the
pelvis, never across the stomach, and always
lie flat so that no pressure is exerted on the
abdomen.
● Always engage the retractor lock when you
are securing a child seat in group 0, 0+ or 1

How the seat belt tensioner works During a frontal collision, the seat belts on
the front seats are retracted automatically.
The seat belts for the occupants in the front
seats are equipped with belt tensioners. Sen-
sors will trigger the belt tensioners only dur-
ing severe head-on, lateral and rear-end colli-
sions and only if the seat belt is worn. The
tensioners retract and tighten the seat belts,
reducing the forward motion of the occu-
pants.
The seat belt tensioner can be triggered only
once.
The seat belt tensioners will not be triggered
in the event of a light frontal, side or rear col-
lision, if the vehicle overturns or in situations
where no large forces act on the front, side or
rear of the vehicle.
Note
● If the seat belt tensioners 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. Specialised work-
shops are familiar with these regulations,
which are also available to you. Service and disposal of belt
tensioners
The belt tensioners are components of the
seat belts that are installed in the seats of
your vehicle. If you work on the belt tension-
ers 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 ten-
sioner is not reduced and that removed parts
do not cause any injuries or environmental
pollution, regulations, which are known to
the specialised workshops, must be ob-
served.
WARNING
● Improper use or repairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
install parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic 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 16

Airbag system
work, must be performed by a specialised
workshop only.
●
The belt tensioners will only provide pro-
tection for one accident and must be changed
if they have been activated. Airbag system
Brief introduction Why 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.
The airbag system is not a substitute for seat
belts, but it is an integral part of the vehicle's
overall passive safety system. Please bear in
mind that the airbag system can only work ef-
fectively when the vehicle occupants are
wearing their seat belts correctly and have
adjusted the head restraints properly. There-
fore, it is most important to wear the seat
belts at all times, not only because this is re-
quired by law in most countries, but also for
your safety
›››
page 11, The reason why we
should wear seat belts .
The airbag inflates in a matter of seconds, so
if you are not properly seated when the air-
bag is triggered, you may sustain fatal inju-
ries. Therefore, it is essential that all vehicle
occupants assume a correct sitting position
while travelling.
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 occu-
pant. This also applies to children.
Always maintain the greatest possible dis-
tance between yourself and the front airbag.
This way, the front airbags can completely
deploy when triggered, providing their maxi-
mum protection.
The most important factors that will trigger
an airbag are: the type of accident, the angle
of collision and the speed of the vehicle.
Whether or not the airbags are triggered de-
pends primarily on the vehicle deceleration
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 speci-
fied reference values, the front, side and/or
curtain airbags will not be triggered. Take in-
to account that the visible damage in a vehi-
cle involved in an accident, no matter how
serious, is not a determining factor for the
airbags to have been triggered.
WARNING
● Wearing the seat belt incorrectly or assum-
ing an incorrect sitting position can lead to
critical or fatal injuries.
● All vehicle occupants, including children,
who are not properly belted can sustain criti-
cal or fatal injuries if the airbag is triggered. » 17Technical specifications

Safety
Children up to 12 years old should always
travel on the rear seat. Never transport chil-
dren 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, or 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 in-
creased if you are struck by an inflating air-
bag.
● To reduce the risk of injury from an inflating
airbag, always wear the seat belt properly
››› page 11.
● Alw
ays adjust the front seats properly. Description of airbag system
The airbag system mainly comprises (as per
vehicle equipment):
●
an electronic control and monitoring sys-
tem (control unit)
● frontal airbags for driver and passenger,
● side airbags,
● curtain (head) airbags,
● a control lamp  on the dash panel
››› page 19 .
● a k ey

-operated switch for front passenger
airbag, ●
a control lamp for disabling/enabling the
front passenger airbag.
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp  :
● does

not light up when the ignition is
switched on ››› page 19,
● turn

s off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor 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 6, Proper sitting po-
sition for occupants. ●
If a fault has occurred in the airbag system,
have the system checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thousandths of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special cases of an accident, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags
do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. There are some factors that play an
important role, such as the properties of the
object the vehicle hits (hard/soft), angle of
impact, vehicle speed, etc.
The deceleration trajectory is key for airbag
activation.
18

Airbag system
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in
serious head-on collisions
● Driver airbag.
● Front passenger front airbag.
The following airbags are triggered in
serious side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear side airbag on the side of the acci-
dent.
● Curtain airbag on the side of the accident.
In an accident with airbag activation:
● the interior lights switch on (if the interior
light switch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut. Control lamp for airbag and seat belt
tensioner
 The control lamp monitors all airbags and
seat belt tensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner
system
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. Each time the ignition is switched on,
the control lamp
 illuminates for several
seconds (self-diagnosis) and the instrument
panel display* shows AIRBAG/TENSIONER
.
The system must be checked when the
control lamp  :
● does not light up when the ignition is
switched on,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
In the event of a malfunction, the warning
lamp remains on continuously. In addition,
depending on the malfunction, a fault mes-
sage appears on the instrument panel dis-
play for approximately 10 seconds and a
short audible warning is given. In this event, you should have a specialised workshop
check the system immediately.
If any of the airbags are disabled by a Techni-
cal Service, the warning lamp flashes for sev-
eral more seconds after verification and will
turn off if there is no fault.
WARNING
● If there is a malfunction, the airbag and
belt tensioner system cannot properly per-
form its protective function.
● If a malfunction occurs, have the system
checked immediately by a specialised work-
shop. Otherwise, in the event of an accident,
the airbag system and belt tensioners may
not be triggered, or may not be triggered cor-
rectly. 19Technical specifications
