ar
t of the seat belt must lie across
the pelvis, never across the stomach.
● The seat belt must lie flat and fit comforta-
bly. P
ull the belt tight if necessary to take up
any slack.
In the case of pregnant women , the seat belt
must lie evenly across the chest and as low
as possible over the pelvis, never across the
stomach and must be worn properly at all
times during the pregnancy ››› Fig. 73.
Adapting the position of the belt webbing to
your size
The seat belt can be adapted using the fol-
lowing equipment:
● Front seat height adjustment. WARNING
An incorrectly worn seat belt web can cause
sever e or f

atal injuries in the event of an acci-
dent.
● The seat belt cannot offer its full protection
unl
ess the seat backrest is in an upright posi-
tion and the seat belt is worn correctly, ac-
cording to your size.
● Unbuckling your seat belt while the vehicle
is in motion c
an cause severe or fatal injuries
in the event of an accident or sudden braking.
● The seat belt itself or a loose seat belt can
cause sev
ere injuries if the belt moves from hard areas of the body to soft areas (e.g. the
st
om

ach).
● The shoulder part of the seat belt must lie
on the centre of
the shoulder, never across
the neck or the arm.
● The seat belt must lie flat and fit comforta-
bly on the t
orso
● The lap part of the seat belt must lie across
the pelvis, nev
er across the stomach. The
seat belt must lie flat and fit comfortably on
the pelvis Pull the belt tight if necessary to
take up any slack.
● For pregnant women, the lap part of the
seat belt
must lie as low as possible over the
pelvis and always lie flat, “surrounding” the
stomach.
● Do not twist the seat belt while it is fas-
tened.
● Never p

ull the seat belt away from your
body us
ing your hand.
● Do not lie the seat belt across rigid or frag-
ile o
bjects, e.g. glasses, pens or keys.
● Never use seat belt clips, retaining rings or
simil
ar instruments to alter the position of
the belt webbing. Note
If your physical constitution prevents you
from m aint

aining the correct position of the
belt webbing, contact a specialised workshop
for help with any special devices to ensure
the optimum protection of the seat belt and airbag. SEAT recommends taking your car in

ing important functions:
Automatic belt retainer
Every seat belt is equipped with an automatic
belt retainer on the shoulder belt. If the belt
is pulled slowly or during normal driving, the
system allows for total freedom of movement
on the shoulder belt. However, during sud-
den braking, during travel in mountains or
bends and during acceleration, the automat-
ic belt retainer on the seat belt is locked is
pulled quickly.
Belt tensioners
The seat belts for the occupants in the front
seats are equipped with belt tensioners.
Sensors trigger the belt tensioners during se-
vere head-on, lateral and rear collisions and
retract and tighten the seat belts. If the seat
belt is loose, it is retracted to reduce the for-
wards movement of occupants or movement »

if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is
produced. This is normal and it is not an indi-
cation of fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the force of
the seat belt on the body in the event of an
accident. Note
The relevant safety requirements must be ob-
serv ed when the

vehicle is dismantled or sys-

ice

s If you work on the belt tensioners or remove
and in
s
t

all other parts of the vehicle when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or not at all. So that the effectiveness of the belt tensioner
is not

reduced and that removed parts do not
cause any injuries or environmental pollu-
tion, regulations must be observed. These re-
quirements are known to specialised work-
shops. WARNING
● Improper u se or r

epairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
inst
all parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic r
etractor cannot be repaired.
● Any work on the belt tensioners and seat
belts, includin
g the removal and refitting of
system parts in conjunction with other repair
work, must be performed by a specialised
workshop only.
● The belt tensioners will only provide pro-
tection for one ac

Brief intr
oduction
Intr

oduction Front airbags have been installed for both
driver and p
a

ssenger. The front airbags can
also protect the chest and head of driver and
passenger if the seats, seat belts head re-
straints and, for the driver, the steering
wheel are correctly adjusted and used. Air-
bags are considered as additional safety
equipment. An airbag cannot replace the
seat belt, which must be worn at all times,
even in front seats where front airbags have
been installed.
The airbag can protect vehicle occupants in
the event of an accidents, cushioning 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 deployment space within frac-
tions of a second. When an occupant with the
seat belt properly fastened puts pressure on
the inflated airbag, the propellant gas es-
capes 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
58

Airbag system
as swelling, bruising and skin injuries can be
ru l
ed 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 character-
istics of the object the vehicle hits. Therefore,
airbags are not triggered every time the vehi-
cle is visibly damaged.
The activation of the airbag system depends
on the magnitude of the deceleration of the
vehicle caused by a collision, which registers
through an electronic control unit. If the de-
celeration magnitude value is below the ref-
erence value programmed in the control unit,
the airbags will not deploy even though seri-
ous damage might be caused to the vehicle
as the result of an 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 impossible 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 an-
gles resulting in the deployment of the air-
bag. Factors necessary for the airbag to be
deployed can be, the characteristics of the
object (hard or soft) against which the vehi- cle collides, the collision angle and the vehi-
cle s
peed.
Airbags act in conjunction with the three-
point seat belts in certain accident situa-
tions, when the vehicle deceleration rate is
severe enough to trigger the airbags. Airbags
only deploy once and only under certain cir-
cumstances. Seat belts remain present to of-
fer protection in situations where airbags are
not triggered or where they have already de-
ployed. For example, when a vehicle hits an-
other after an initial collision or is hit by an-
other vehicle.
The airbag system is an integral part of the
car's passive safety system. The airbag sys-
tem can only work effectively when the vehi-
cle occupants are wearing their seat belts
correctly and have adjusted the head re-
straints properly  ››› page 48. WARNING
Never exclusively trust the airbag system as a
mean s

of protection.
● Even when triggered, airbag protection is
only aux
iliary.
● The airbags provide the best protection
when the seat belt
s are properly fastened,
thus reducing the risk of sustaining injuries
››› page 52, Why wear a set belt .
● Before each trip, every occupant must sit
properly, c
orrectly fasten the seat belt be-
longing to his or her seat and keeping it fas- tened throughout the trip. This rule is valid
for a
l

l vehicle occupants. WARNING
Occupants sitting in the front of the vehicle
mu st

never carry any objects in the deploy-
ment space between them and the airbags,
as this increases the risk of sustaining inju-
ries 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 whil
e the vehicle is in motion.
● Never transport objects on the front pas-
senger se
at. In the event of sudden braking
and manoeuvres, the objects may end up in
the airbag deployment space and fly uncon-
trollably around the interior if the airbag is
activated.
● Occupants of the front and rear seats must
never carr
y any other people, pets or objects
in the deployment space between them and
the airbags. Make sure children and other
passengers also respect this recommenda-
tion. WARNING
The airbag system provides protection for
one acc ident

only. If they have been de-
ployed, they must be replaced. » 59

●
Ens ur
e deployed airbags and the system
components involved are immediately re-
placed with new, SEAT-approved components
for the vehicle.
● Have any repairs or modifications carried
out at a s
pecialised workshop. Specialised
workshops have the necessary tools, diag-
nostics equipment, repair information and
qualified personnel.
● Never fit recycled or reused airbag compo-
nents in
your vehicle.
● Never modify the airbag system compo-
nents. WARNING
If the airbags are triggered, a fine dust is pro-
duced. Thi

s is normal and it is not an indica-
tion of fire in the vehicle.
● This fine dust may irritate the skin and eyes
and cause br
eathing difficulties, particularly
in people suffering from or who have suffered
from asthma or other illnesses of the respira-
tory tract. To reduce breathing difficulties,
get out of the vehicle and open and doors and
windows to breath in fresh air.
● Should you touch the dust, wash your
hands
and face using a mild soap and water
before you eat.
● Prevent the dust from affecting the eyes or
open wound
s.
● Rinse your eyes with water if you have dust
in them. WARNING
Solvents cause the surfaces of the airbag
modul e

s to become porous. If an airbag is ac-
cidentally triggered, the detachment of plas-
tic parts could cause serious injury.
● Never clean the dash panel and the surfa-
ces

WARNING
● The seat belt
s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 48.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thou
s
andths

of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion 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-
tory and activates 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.

Introduction Before transporting babies and children in a
chi
l

d seat placed in the front passenger seat,
first completely read the information regard-
ing the airbag system.
This information is extremely important for
driver and passenger safety, particularly that
of babies and children.
SEAT recommends the use of child seats from
the SEAT accessory programme. These child
seats have been designed and tested for use
in SEAT vehicles. You can purchase child
seats with different mountings from a SEAT
dealership. WARNING
Make sure children are properly belted in and
corr ectly

secured to avoid severe or fatal inju-
ries while the vehicle is in motion.
● Never use a rear-facing child seat in the
front p
assenger seat if the front passenger
front airbag is enabled.
● Children up to 12 years old should always
travel
on the rear seat. ●
Chil dr

en must always be protected with an
approved child restraint system suited to
their height and weight.
● Children must assume the proper sitting
position and be pr
operly belted in while trav-
elling.
● Ensure the seat backrest is upright when a
chil
d seat is being used on it.
● Do not allow the child's head or other part
of his
or her body to enter the deployment
area of the side airbags.
● Make sure the belt webbing is correctly
positioned.
● Nev

er hold children or babies on your lap or
in your arms.
● On

ly one child may occupy a child seat.
● Please read and observe the child seat
manufact
urer's handling instructions. WARNING
An empty or loose child seat could fly uncon-
tro l

lably around the vehicle interior and
cause injuries in the event of an accident or
sudden braking.
● When not in use while the vehicle is in mo-
tion, alwa
ys safely secure the child seat or
store it in the luggage compartment. Note
Replace the child seat after an accident, as it
ma y

have invisible damage. Important information regarding the

.
The passenger side front airbag, when ena-
bled, is a serious risk for a child that is facing
backward since the airbag can strike the seat
with such force that it can cause serious or
fatal injuries. Children up to 12 years old
should always travel on the rear seat.
Therefore we strongly recommend you to
transport children on the rear seats. This is
the safest location in the vehicle. Alternative-
ly, the front passenger airbag can be disa-
bled with a key-operated switch ›››

When transporting children, use a child seat
suitable for the age and size of each child

Transporting children safely
WARNING
● If a c hi
ld seat is secured to the front pas-
senger seat, the risk to the child of sustain-
ing critical or fatal injuries in the event of an
accident increases.
● An inflating front passenger airbag can
strike the r
ear-facing child seat and project it
with great force against the door, the roof or
the backrest.
● Never install a child seat facing backwards
on the front p
assenger seat unless the front
passenger front airbag has been disabled.
Risk of potentially fatal injuries to the child!
However, if it is necessary, in exceptional ca-
ses, to transport a child in the front passen-
ger seat, the front passenger front airbag
must always be disabled ››› page 63. If the
passenger seat has a height adjustment op-
tion, move it to the highest, most upright po-
sition. If you have a fixed seat, do not install
any child restraint system in this location.
● For those vehicles that do not include a key
lock sw
itch to deactivate the airbag, the vehi-
cle must be taken to a technical service.
● All vehicle occupants, especially children,
must
assume the proper sitting position and
be properly belted in while travelling.
● Never hold children or babies on your lap,
this c
an result in potentially fatal injuries to
the child!
● Never allow a child to be transported in a
vehicl
e without being properly secured, or to
stand up or kneel on a seat while travelling.
In an accident, the child could be flung through the vehicle, causing possibly fatal in-
juries
t

o themselves and to the other vehicle
occupants.
● If children assume an improper sitting posi-
tion when the vehic
le is moving, they expose
themselves to greater risk of injury in the
event of a sudden braking manoeuvre or in an
accident. This is particularly important if the
child is travelling on the front passenger seat
and the airbag system is triggered in an acci-
dent; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave a child alone in the child seat
or inside the
vehicle because depending on
the season, very high temperatures may be
reached inside a parked vehicle, which could
be fatal.
● Children who are less than 1.5 metres tall
must
not wear a normal seat belt without a
child seat, as this could cause injuries to the
abdominal and neck areas during a sudden
braking manoeuvre or in an accident.
● Do not allow the seat belt to become twis-
ted and the seat
belt should be properly in
place ››› page 52.
● Only one child may occupy a child seat
