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.

● 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.

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.

● 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. 

WARNING
In the event of a fault in the airbag system, the airbag may not trigger
correctly, may fail to trigger or may even trigger unexpectedly, leading to
severe or fatal injuries.
● Have the airbag system checked immediately by a Specialised work-
shop.
● Never mount a child seat in the front passenger seat or remove the
mounted child seat! The front passenger airbag may deploy during an ac-
cident in spite of the fault.
CAUTION
Always pay attention to any lit lamps and to the corresponding descriptions
and instructions to avoid damage to the vehicle. 
Description and function of the airbag
The airbag can protect vehicle occupants in the event of an accidents, cush-
ioning the movement of the occupants in the direction of the collision in
frontal and side accidents.
Deployed airbags fill with a propellant gas. This causes the airbag covers to
break and the airbags to deploy extremely quickly in their entire deploy-
ment space within fractions of a second. When an occupant with the seat
belt properly fastened puts pressure on the inflated airbag, the propellant
gas escapes to absorb the force of the impact and slow the movement. This
reduces the risk of severe or fatal injuries. Airbag deployment does not
mean that other types of injury such as swelling, bruising and skin injuries
can be ruled out. Upon deployment of the airbag, friction can cause the
generation of heat.
Airbags do not protect the arms or the lower part of the body. The most important factors for triggering the airbag are the type of accident,
the angle of impact, the vehicle speed and the characteristics of the object
the vehicle hits. Therefore, airbags are not triggered every time the vehicle
is visibly damaged.
The activation of the airbag system depends on the magnitude of the decel-
eration of the vehicle caused by a collision, which registers through an elec-
tronic control unit. If the deceleration magnitude value is below the refer-
ence value programmed in the control unit, the airbags will not deploy de-
spite serious damage being caused to the vehicle by the accident. Damage
suffered by the vehicle, reparation costs or absence of damage suffered
from the accident are not indications of whether an airbag should have
been deployed. Due to the varying nature of collision situations, it is impos-
sible to define a speed range of the vehicle and reference values. For this
reason, it is not possible to cover all types of collisions and collision angles
resulting in the deployment of the airbag. Factors necessary for the airbag
to be deployed can be, the characteristics of the object (hard or soft)
against which the vehicle collides, the collision angle and the vehicle
speed.
Airbags act in conjunction with three-point seat belts in the event of certain
accidents, when the vehicle deceleration rate is severe enough to trigger
the airbags. Airbags only deploy once and only under certain circumstan-
ces. Seat belts remain present to offer protection in situations where air-
bags are not triggered or where they have already deployed. For example,
when a vehicle hits another after an initial collision or is hit by another vehi-
cle.
The airbag system is an integral part of the vehicle's passive safety system.
The airbag system can only work effectively when the occupants are wear-
ing their seat belts correctly and have adjusted the head restraints properly

Vehicle safety components
The following safety equipment makes up the vehicle safety design to re-
duce the risk of severe and fatal injuries. Depending on the vehicle equip-
ment, some equipment may not be fitted in the vehicle or may not be avail-
able in some markets. 

When the front airbags are triggered they fill the zones marked in
red ⇒ Fig. 47 and ⇒ Fig. 48 (radius of action). Therefore, objects should
never be placed or mounted in these areas ⇒ 
. Factory-fitted accessories
are outside the range of the front airbag for the driver and the front passen-
ger, e.g. the baseplate for the mobile telephone support.
The airbag covers fold out of the steering wheel ⇒ Fig. 47 or dash panel
⇒ Fig. 48 when the driver and front passenger airbags are triggered. The air-
bag covers remain connected to the steering wheel or the dash panel.
WARNING
The airbag is deployed at high speed in fractions of a second.
● Always keep the deployment areas of the front airbags vacant.
● Never secure objects to the covers or in the deployment area of the
airbag modules, e.g. drink holders or phone supports.
● The deployment space between the front passengers and the airbags
must not in any case be occupied by other passenger, pets and objects.
● Never fix any object to the windscreen above the front airbag on the
front passenger side.
● Do not alter, cover or stick anything to the steering wheel hub or the
surface of the airbag module on the passenger side of the dash panel.
WARNING
Front airbags are deployed in front of the steering wheel ⇒ Fig. 47 and
the dash panel ⇒ Fig. 48.
● When driving, always hold the steering wheel on the outer edge of
the ring with both hands: 9 o'clock and 3 o'clock position.
WARNING (Continued)
● Adjust the driver seat so that there is a distance of at least
25 cm(10 inches) between the centre of your chest and the hub of the
steering wheel. If you physical constitution prevents you from meeting
these requirements, make sure you contact a Specialised workshop.
● Adjust the front passenger seat so there is as much distance as possi-
ble between the front passenger and the dash panel.
