Seat belts
●
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. Head-on collisions and the laws of
physics
Fig. 62
A driver not wearing a seat belt is
thrown forward violently Fig. 63
The unbelted passenger in the rear
seat is thrown forward violently, hitting the
driver who is wearing a seat belt. It is easy to explain how the laws of physics
work in the case of a head-on collision: when
a vehicle starts moving, a type of energycalled “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
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 ki-
netic energy 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 great that it is not

it means, for example, that the tyre was man-
ufactured in the 22nd week of 2012.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the tyres rub against the bodywork, in certain
circumstances the tyres , suspension or
bodywork and pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If you use tyres that are approved by SEAT
you can be sure that the actual tyre dimen-
sions will be correct for your vehicle. If you
decide to fit a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres respecting the envi-
ronment. WARNING
● It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads.
●
Avoid running the vehicle on tyres that are
more than 6 years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● If wheel trims are fitted after the car is pur-
chased, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● Never mount used tyres if you are not sure
of their “previous history”.
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

When installing different wheels (for instance
alloy wheels or wheels with winter tyres) it is
important to use the correct wheel bolts with
the right length and correctly shaped bolt
heads. This ensures that wheels are fitted »
