Seat belts
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
retractor
s may not work properly. Head-on collisions and the laws of

Safety
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 belt is not positioned correctly.
● Adjust the seat and head restraint correctly.
● To fasten the belt, take hold of the latch
plate and p
ull it slowly across your chest and
lap.
● Insert the latch plate into the buckle for the
appropriat
e seat and push it down until it is
securely locked with an audible click
››› Fig. 83.
● Pull the belt to ensure that the latch plate is
securely en
gaged 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 e a
si

ly and the trim is not damaged.
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.
● Always engage the retractor lock when you
are securing a c
hild seat in group 0, 0+ or 1

and tight en
s the seat belts, reducing
the forward motion of the occupants.
The belt tensioners will not be triggered in
the event of minor collisions, if the vehicle
overturns, or in accidents where no major
forces act on 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
observ
ed 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 tension-
er
s The belt tensioners are components of the
se
at
belts th

at 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 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
the specialised workshops, must be ob-
served. WARNING
● Improper use or r ep

airs 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
insta
ll parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic retr
actor cannot be repaired.
● Any work on the belt tensioners and seat
belts, including the r
emoval and refitting of
system parts in conjunction with other repair
work, must be performed by a specialised
workshop only.
● The belt tensioners will only provide pro-
tection for one acc
ident and must be changed
if they have been activated. Airbag system
Brief intr
oduction
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
for passengers.
● If a fault has occurred in the airbag system,

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-
dent.
● 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-
sioner  The control lamp monitors all airbags and
seat belt
t

ensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner sys-
tem
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-
ed on (self-diagnosis).
The system must be checked when the con-
trol lamp  :
● does not light up when the ignition is
switc hed on,
● t

urns 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.
In the ev

ent of a malfunction, the warning
lamp remains on continuously. Have the air-
bag system inspected immediately by a spe-
cialised workshop.

● If y ou do not

wear a seat belt, if you lean
forward, or are not seated correctly while the
vehicle is in motion, you are at a greater risk
of injury if the side airbag system is triggered
in an accident.
● In order for the side airbags to provide their
maximum prot
ection, the prescribed sitting
position must always be maintained with
seat belts fastened while travelling.
● Occupants of the outer seats must never
carry an
y objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to the doors. This would impair the protection
offered b
y

the side airbags.
● The built-in coat hooks should be used only
for lightweight c
lothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must not
be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered.
● Under no circumstances should protective
cover
s be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the seams
of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; rep
lace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval
and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.

The side and hea d airb
ags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain (head) airbags neither
the doors nor the door panels should be
modified in any way (e.g. fitting loudspeak-
ers). If the front door is damaged, the airbag
system may not work correctly. All work car-
ried out on the front door must be done in a
specialised workshop.
● In a side-on collision the side airbags will
not work if
the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-

● Never drive if the interior door panels have
been removed or if
the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
