Seat belts
Head-on collisions and the laws of
physics Fig. 8
A driver not wearing a seat belt is thrown
f orw
ard violently. Fig. 9
The unbelted passenger in the rear seat
is thr o
wn forward violently, hitting the driver
who is wearing a seat belt. The effects of the laws of physics in the case
of a head-on collision ar
e easy t
o explain: the
moment a vehicle starts moving, a type of en- ergy called “kinetic energy” starts acting on
both the vehicl
e 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 great that it is not possible to brace oneself with one's hands. In
a front
al collision, unbelted passengers are
thrown forward and will make violent contact
with the steering wheel, dash panel, wind-
screen or whatever else is in the way
››› Fig. 8.
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. 9

Chil
d safety
Introduction For safety reasons, as we have learned from
accident st
atistics, w
e recommend that chil-
dren under 12 years of age travel in the rear
seats. Depending on their age, height and
weight, children travelling in rear seats must
use a child seat or a seat belt. For safety rea-
sons, the child seat should be installed in the
rear seat, behind the front passenger seat or
in the centre back seat.
The physical laws involved and the forces
acting in a collision apply also to children
››› page 19. But unlike adults, children do not
have fully developed muscle and bone struc-
tures. This means that children are subject to
a greater risk of injury.
To reduce the risk of injuries, children must al-
ways use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety prod-
ucts from the SEAT Original Accessories Pro-
gramme, which includes systems for all ages
made by “Peke” (not for all countries) (see
www.seat.com). These systems have been especially de-
signed and appr
o
ved, complying with the
ECE-R44. regulation.
SEAT recommends securing the child seats
shown on the website as described below:

››› page 109 WARNING
If a lot of snow builds up on the rear lid or it
is heavily l oaded, the r
ear lid may not open
or, after opening, it may lower by itself due
to the extra weight and cause serious in-
jury.
Driving
for a minimum of about 5 seconds already
sav es mor
e than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high during
this initial warm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level. Check tyre pressure
Alw
ays make sure the tyres are inflated to the
correct pressures ››› page 356
to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as
they increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aero-
dynamic drag of the vehicle, you should re-
move it when not needed. At speeds of
100-120 km/h (62-75 mph), this will save 12%
of fuel.
Save electrical energy
The engine drives the alternator, thereby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*. Plug-in hybrid drive: brak
e early and evenly
to take advantage of energy recovery. Note
Towing bracket device*
correct figures for your specific model, which
may be l o
wer than these figures, are given in
the vehicle documentation. The information in
the vehicle documentation takes precedence
at all times.
To promote safety while driving, SEAT recom-
mends making the most of the maximum ver-
tical load technically permissible on the
coupling device ››› page 306
. An insufficient
vertical load has a negative influence on the
behaviour of both the vehicle and trailer.
The vertical load increases the weight on the
rear axle, reducing the vehicle's carrying ca-
pacity.
Gross combination weight of the towing
vehicle and trailer
The gross combination weight is the actual
weight of the loaded vehicle plus the actual
weight of the loaded trailer.
In some countries trailers are classified into
distinct categories. SEAT recommends ob-
taining information from a specialised work-
shop regarding which type of trailer is most
suitable for your vehicle.
Trailer loading
The weight of the towing vehicle and trailer
must be balanced. In order to do this, the
load must be as close as possible to the max-
imum vertical load technically permissible on
the coupling point, and it must be evenly dis- tributed between the back and front of the
trail

Wheels
The performance of winter tyres is also se-
v er
ely impaired by ageing, even if the tread is
still much deeper than 4 mm.
A code letter indicating the speed limit is
stamped on all winter tyres ››› page 354
.
Vehicles capable of exceeding these speeds
must have an appropriate sticker attached
so that it is visible to the driver. Suitable stick-
ers are available from the SEAT Official Serv-
ice and specialised workshop. Please note
the regulations to this effect in your country.
“All-weather” tyres can also be used instead
of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable
240 km/h (149 mph) speed for winter tyres
with the letter V is subject to technical re-
strictions; the maximum permissible speed
for your vehicle may be significantly lower.
The maximum speed limit for these tyres de-
pends directly on the maximum axle weights
for your car and on the listed weight rating of
the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted
f or the wint
er tyres fitted on your car can
cause tyre failure, resulting in a loss of con-
trol of the vehicle – risk of accident. For the sake of the environment
When winter is over, change back to sum-
mer t yr
es at an appropriate moment. In
temperatures above +7°C (+45°F), perform-
ance will be improved if summer tyres are
used. Fuel consumption, wear and noises
while driving will all be reduced. Snow chains
Snow chains must only be fitted t
o the fr
ont
wheels, even on vehicles with four-wheel
drive.
Indications about the technical data
Empty weight, total weight, axle loads
The empt y w
eight of the vehicle with driver
(75 kg) was calculated according to the (EU)
1230/2012 standard. Optional equipment can
increase the empty weight, which means that
the possible useful load decreases propor-
tionally.
Trailer weight
The maximum permitted drawbar load on the
ball head of the towing bracket is 80 kg. WARNING
The values indicated for the maximum per-
mitt ed w
eights must not be exceeded.
There is a risk of accident and damage! 381
