Alwa y
s keep your feet in the footwell when
the vehicle is moving; never rest them on the
dash panel, out the window or on the seat. An
incorrect sitting position exposes you to an
increased risk of injury in case of a sudden
braking or an accident. If the airbag is trig-
gered, you could sustain severe injuries due
to an incorrect sitting position.
● To reduce the risk of injury to the front pas-
senger in event
s such as sudden braking ma-
noeuvres or an accident, never travel with the
backrest tilted far back! The airbag system
and seat belts can only provide optimal pro-
tection when the backrest is in an upright po-
sition and the front passenger is wearing his
or her seat belt properly. The further the seat
backrests are tilted to the rear, the greater
the risk of injury due to incorrect positioning
of the belt web or to the incorrect sitting po-
sition!

These also help pre-
vent uncontrolled movements that may result
in serious injury and reduce the risk of being
thrown out of the vehicle.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas- sive safety features (such as the airbag sys-
tem) are des

igned to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing 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 when
involved 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 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!

Safety instructions on using seat
belt s –
Always wear the seat belt as described in
this section.
– En s
ure that the seat belts can be fastened
at all time
s and are not damaged. WARNING
● If seat belt

s are worn incorrectly or not at
all, the risk of severe injuries increases. 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 t
own. Other vehicle oc-
cupants 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 s
ame 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 w
orn.
● The seat belt should never lie on hard or
fragile o
bjects (such as glasses or pens, etc.)
because this can cause injuries. ●
Do not al lo

w 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 incorr
ect position.
● Loose, bulky clothing (such as an overcoat
over a jac
ket) 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 w
ith paper or other objects, as this
can prevent the latch plate from engaging se-
curely.
● Never use seat belt clips, fastening rings or
similar it
ems to alter the position of the belt
webbing.
● Frayed or torn seat belts or damage to the
connections, belt r
etractors 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 stret
ched 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 your
self. The seat belts must not be re-
moved or modified in any way.
● The belts must be kept clean, otherwise the

called “kinetic energy” is created both in the
p a
ssen
gers 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 bod-
ies 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 col
lision 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. 81.
It is also important for 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. 82. How to properly adjust your

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

Positioning seat belts
Seat belts offer their maximum protection on-
ly when they are properly positioned. WARNING
● The seat belt s

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 w

orn 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 shou
lder, never across
the neck. The seat belt must lie flat and fit
comfortably on the torso
● The lap part of the seat belt must lie across
the pelvis, never ac
ross the stomach. The
seat belt must lie flat and fit comfortably on
the pelvis Pull the belt tight if necessary to
take up any slack.
● For pregnant women, the lap part of the
seat belt mu
st 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 ››› Fig. 84.

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 may not
function 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, re

gulations, which are known to

Brief intr

Wh y

is it so important to wear a seat
belt and to sit correctly? For the inflating airbags to achieve the best
protection, the se
at

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 properly wear the
seat belts at all times, not only because this
is required by law in most countries, but also
for your safety ›››
page 61, Why wear a seat
belt?.
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
66

Airbag system
airbag. In this case, the inflating airbag may
inflict c
ritic al
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
● Wearin g the se

at 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.
Children up to 12 years old should always travel on the rear seat. Never transport chil-
dren in the v
ehic

le 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 for
ward 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, alwa
ys wear the seat belt properly.
● Always adjust the front seats properly. Description of airbag system
The airbag system mainly comprises (as per
v
ehic
le equipment):
● an el

ectronic control and monitoring sys-
tem (contro
l unit)
● frontal airbags for driver and passenger,
● side airbags,
● curtain airbags,
● a control lamp  on the dash panel
›

›› page 68.
● key-operated switch for front passenger air-
bag,
● a contro

l lamp for disabling/enabling the
front pa
ssenger airbag. The airbag system operation is monitored
electronical

ly. 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 68,
● turns off after 4 seconds after the ignition
is swit
ched on
● turns off and then lights up again after the
ignition is swit
ched on
● illuminates or flashes while the vehicle is
moving.
The airb

ag 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 belt s

and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 57, Correct position

frontal collision the system might not trigger
correctly
or m
ay 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 accidents instances, 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. Some factors play an important role,
such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation. The control unit analyses the collision trajec-
tory
and activ

ates 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 seri-
ous head-on collisions
● Driver airbag.
● Front passenger front airbag
The follo
wing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear s

ide airbag on the side of the acci-

● Curt

ain (head) airbag on the side of the ac-
cident.
In an acc

ident with airbag activation:
● the interior lights switch on (if the interior
light switc
h is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut. Airbag control lamp and seat belt ten-

Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. The control lamp  will light up for a
few seconds every time the ignition is switch-
