Important safety instructions for
the use of seat belts

Seat belts
moment a vehicle starts moving, a type of en-
er gy call
ed “kinetic energy” starts acting on
both the vehicle and its passengers.
The amount of “kinetic energy” depends on
the speed of the vehicle and on the weight of
the vehicle and of its passengers. The higher
they are, the more energy there is to be “ab-
sorbed” in the event of 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 kinetic ener-
gy is multiplied by four.
Given that the passengers of the vehicle in
our example do not have their seat belts fas-
tened, in the event of a collision the entire
amount of the passengers' kinetic energy will
be only absorbed by the mentioned 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 collision are so gr
eat that it is not
possible to brace oneself with one's hands. In
the event of a head-on collision, vehicle oc-
cupants not wearing a seat belt will be
thrown uncontrollably forward and will col-
lide, for example, against the steering wheel,
instrument panel or windscreen ››› Fig. 7.
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. If a rear seat
occupant is not wearing a seat belt, they are
not only endangering themselves but also
the occupants of the front seats ››› Fig. 8. How to properly adjust your

tensioners or remove and install parts of the
syst em when perf
orming other repair work,
the seat belt may be damaged. The conse-
quence may be that, in the event of an acci-
dent, 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, regulations, which are known to the
specialised workshops, must be observed. WARNING

Airbag system
Sharp braking before an accident may cause
a passenger not w earing a seat belt t
o 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 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 for triggering the
airbag are the type of accident, the angle of
impact and the vehicle speed.
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 into
account that the visible damage in a vehicle
involved in an accident, no matter how seri-
ous, is not a determining factor for the air-
bags to have been triggered. WARNING

Safety
system may fail to trigger, or not trigger
corr
ectly. Airbag activation
The airbags deploy extremely rapidly, within
thousands of a second, t
o pr
ovide additional
protection in the event of an accident. A fine
dust may develop when the airbag deploys.
This is normal and it is not an indication 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-
t
ory 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:
