Seat belts
Introduction
Check the condition of all the seat belts at regular intervals. If you notice
that the belt webbing, fittings, retractor mechanism or buckle of any of the
belts is damaged, the belt must be replaced immediately by a Specialised
workshop ⇒ 
. The Specialised workshop must use the appropriate spare
parts corresponding to the vehicle, the equipment and the model year. SEAT
recommends visiting a Technical Service.
Additional information and warnings:
● Adjust the seat position ⇒ page 48
● Airbag system ⇒ page 67
● Child seats (accessories) ⇒ page 76
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
Unbuckled or badly buckled seat belts increase the risk of severe or even
fatal injuries. The seat belt cannot offer its full protection if it is not fas-
tened and used correctly.
● Seats belts are the most effective ways of reducing the risk of sus-
taining severe or fatal injuries In the event of an accident. Correctly fas-
ten seat belts when the vehicle is in motion to protect the driver and all
vehicle occupants.
● Before each trip, every occupant in the vehicle occupants must sit
properly, correctly fasten the seat belt belonging to his or her seat and
keep it fastened throughout the trip. This also applies to other occupants
when driving in town.
WARNING (Continued)
● When travelling, children must be secured in the vehicle with a child
restraint system suitable for their weight and height and with the seat
belts correctly fastened ⇒ page 76.
● Instruct your passengers to fasten their seat belts properly before
driving off.
● Insert the latch plate into the buckle for the appropriate seat and en-
sure it is engaged. Using the latch plate in the buckle of another seat will
not protect you properly and may cause severe injuries.
● Do not allow liquids or foreign bodies to enter the buckle fastenings.
This could damage the buckles and seat belts.
● Never unbuckle your seat belt when the vehicle is moving.
● Never allow more than one passenger to share the same seat belt.
● Never hold children or babies on your lap sharing the same seat belt.
● Loose, bulky clothing (such as a jacket) impairs the proper fit and
function of the seat belt.
WARNING
It is extremely dangerous to drive using damaged seat belts and could re-
sult in serious injury or loss of life.
● Avoid damaging the seat belt by jamming it in the door or the seat
mechanism.
● If the fabric or other parts of the seat belt are damaged, the seat belts
could break in the event of an accident or sudden braking.
● Always have damaged seatbelts replaced immediately by seat belts
approved for the vehicle in question by SEAT. Seat belts which have been
worn in an accident and stretched must be replaced by a Specialised
workshop. Renewal may be necessary even if there is no apparent dam-
age. The belt anchor points should also be checked.
● Never attempt to repair, modify or remove a seat belt yourself. All re-
pairs to seat belts, retractors and buckles must be carried out by a Speci-
alised workshop.

Frontal collisions and the laws of physics
Fig. 37 Vehicle about to
hit a wall: the occupants
are not wearing seat
belts
Fig. 38 The vehicle hits
the wall: the occupants
are not wearing seat
belts
It is easy to explain how the laws of physics work in the case of a head-on
collision: when a vehicle starts moving ⇒ Fig. 37, this is a certain amount of
energy known as “kinetic energy” both in the vehicle and in the occupants.
The higher the speed and the greater the weight of the vehicle, 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 kinetic energy is multiplied by four.
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 of the vehicle and the occupants, the more energy there
is to be absorbed in an accident.
Vehicle occupants not wearing seat belts are not “attached” to the vehicle.
As a result, in a frontal collision they will continue to move forward at the
speed their vehicle was travelling just before the impact until something
stops them! Because the passengers in our example are not restrained by
seat belts, all of the vehicle occupants' kinetic energy has to be absorbed at
the point of impact ⇒ Fig. 38.

Airbag system Introduction
Front airbags have been installed for both driver and passenger. The front
airbags can also protect the chest and head of driver and passenger if the
seats, seat belts head restraints and, for the driver, the steering wheel are
correctly adjusted and used. Airbags are considered as additional safety
equipment. An airbag cannot replace the safety belt, which must be worn at
all times, even in front seats where front airbags have been installed.
Additional information and warnings:

● Correct sitting position ⇒ page 48
● Seat belts ⇒ page 57
● Child seats (accessories) ⇒ page 76
● Care and cleaning of the vehicle interior ⇒ page 205
● Accessories, parts replacement, repairs and modifications ⇒ page 222
● Notes for the user ⇒ page 233
WARNING
Never exclusively trust the airbag system as a means of protection.
● Even when triggered, airbag protection is only auxiliary.
● The airbags provide the best protection when the seat belts are prop-
erly fastened, thus reducing the risk of sustaining injuries ⇒ page 57,
Seat belts.
● Before each trip, every occupant must sit properly, correctly fasten
the seat belt belonging to his or her seat and keeping it fastened
throughout the trip. This rule is valid for all occupants.
WARNING
Occupants sitting in the front of the vehicle must never carry any objects
in the deployment space between them and the airbags, as this increa-
ses the risk of sustaining injuries if the airbag is triggered. This modifies
the airbag deployment space or the objects may fly uncontrollably and
hit your body.
● Never carry objects in your hand or on your lap while the vehicle is in
motion.
● Never transport objects on the front passenger seat. In the event of
sudden braking and manoeuvres, the objects may end up in the airbag
deployment space and fly uncontrollably around the interior if the airbag
is activated.
● Occupants of the front and rear seats must never carry any other peo-
ple, pets or objects in the deployment space between them and the air-
bags. Make sure children and other passengers also respect this recom-
mendation.
WARNING
The airbag system provides protection for one accident only. If they have
been deployed, replace them.
● Ensure deployed airbags and the system components involved are im-
mediately replaced with new, SEAT-approved components for the vehicle.
● Have any repairs or modifications carried out at a Specialised work-
shop. Specialised workshops have the necessary tools, diagnostics
equipment, repair information and qualified personnel.
● Never fit recycled or reused airbag components in your vehicle.
● Never modify the airbag system components. 

Side airbags
Fig. 50 On the side of
the front seat: location of
the side airbag
Fig. 51 On the left side
of the vehicle: deploy-
ment area of side airbag
The side airbags are located in the outer cushion of the driver and front pas-
senger seat backrests ⇒ Fig. 50. Their position is indicated by the word
“AIRBAG”. The area marked in red ⇒ Fig. 51 indicates the side airbag de-
ployment zone. In the event of a side-on collision, the side airbag will deploy in the side of
the vehicle affected
⇒ Fig. 51, thus reducing the risk of injuries to passen-
gers on the side of the body and the head facing the accident side.
WARNING
The airbag is deployed at high speed in fractions of a second.
● Always keep the deployment areas of the side airbags vacant.
● The deployment space between the front passengers and the airbags
must not in any case be occupied by other passenger, pets and objects.
● Do not mount accessories on the doors.
● Only used protective covers for the seats that are approved for the ve-
hicle. Otherwise, the side airbag would be obstructed when deployed.
WARNING
Incorrect handling of the driver's and front passenger's seat could pre-
vent the side airbag from deploying properly and cause severe injuries.
● Never remove the front seats of the vehicle or modify any of their
components.
● Great forces must not be exerted on the backrest bolsters because
the side airbags might not deploy correctly, might not deploy at all or
might deploy unexpectedly.
● Any damage to the original seat upholstery or around the seams of
the side airbag units must be repaired immediately by a Specialised
workshop.
