● The lap part of the seat belt must lie across
the pelvis, never across the stomach.
● The seat belt must lie flat and fit comforta-
bly. Pull 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. 11 .
Ad aptin
g 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
severe or fatal injuries in the event of an acci-
dent.
● The seat belt cannot offer its full protection
unless 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 can 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 severe injuries if the belt moves from hard areas of the body to soft areas (e.g. the
stomach).
●
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 torso
● The lap part of the seat belt must lie across
the pelvis, never 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 pull the seat belt away from your
body using your hand.
● Do not lie the seat belt across rigid or frag-
ile objects, e.g. glasses, pens or keys.
● Never use seat belt clips, retaining rings or
similar instruments to alter the position of
the belt webbing. Note
If your physical constitution prevents you
from maintaining 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
for technical service.
Seat belt tensioners
Automatic belt retainer, belt
tensioner, belt tension limiter Seat belts are part of the vehicle safety con-
cept
››› page 17 and consist of the follow-
in g impor

tant 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
16

Airbag system
in the direction of the collision. The belt ten-
sioner works in combination with the airbag
system. The belt tensioner will not be trig-
gered in the event of the vehicle overturning
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-
served when the vehicle is dismantled or sys-
tem components are removed. These require-
ments are known to specialised workshops
››› page 17. Service and disposal of belt
tensioners
If you work on the belt tensioners or remove
and install 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 handling and homemade repairs of
seat belts, automatic belt retainers and ten-
sion devices increase the risk of sustaining
severe or fatal injuries. The belt tensioner
may fail to trigger or may trigger in the wrong
circumstances.
● Never attempt to repair, adjust or remove or
install parts of the belt tensioners or seat
belts. Any work must be performed by a spe-
cialised workshop only ››› page 118.
● Belt tensioners and automatic belt retain-
ers cannot be repaired and must be replaced. For the sake of the environment
Airbag modules and belt tensioners may con-
tain perchlorate. Observe the legal require-
ments for their disposal. Airbag system
Brief introduction 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 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

Safety
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 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 speed.
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 6. 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 properly fastened,
thus reducing the risk of sustaining injuries
››› page 11, Using seat belts .
● Before each trip, every occupant must sit
properly, correctly fasten the seat belt be-
longing to his or her seat and keeping it fas- tened throughout the trip. This rule is valid
for all vehicle occupants.
WARNING
Occupants sitting in the front of the vehicle
must 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 while the vehicle is in motion.
● Never transport objects on the front pas-
senger seat. 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 carry 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 accident only. If they have been de-
ployed, they must be replaced. 18

Airbag system
●
Ensure 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 specialised 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. This 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 breathing 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 wounds.
● Rinse your eyes with water if you have dust
in them. WARNING
Solvents cause the surfaces of the airbag
modules 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 of the airbag modules with cleaners con-
taining solvents. Description of airbag system
Vehicle safety components
The following safety equipment makes up the
vehicle safety design to reduce the risk of se-
vere and fatal injuries. Depending on the ve-
hicle equipment, some equipment may not
be fitted in the vehicle or may not be availa-
ble in some markets.
●
Optimised seat belts for all seats.
● Seat belt tension devices for driver and
passenger.
● Seat belt force limiters for driver and pas-
senger.
● Seat belt warning lamp
● Front airbags for driver and passenger.
● Side airbags for driver and passenger.
● Airbag control lamp .
● Control units and sensors. ●
Head restraints optimised for rear-end colli-
sion.
● Adjustable steering column.
● If necessary, anchor points for child seats
for the rear seats.
● Where applicable, mountings for the child
seat upper retaining strap.
Situations in which the front and side
airbags do not deploy:
● If the ignition is switched off during the col-
lision.
● In frontal collisions, when the deceleration
measured by the control unit is too low.
● In minor side collisions.
● In rear collisions.
● In the event of the vehicle overturning.
● When the impact speed is lower than the
reference value set in the control unit.
There is a fault in the system if the control
lamp :
● does not light up when the ignition is
switched on,
● turns off after 4 seconds after the ignition
is switched on

WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 6.
● If a f
ault has occurred in the airbag system,
have the system 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
thousandths 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.
The following airbags are triggered in
serious head-on collisions
● Driver airbag.
● Front passenger front airbag
The following airbags are triggered in
serious side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear side airbag on the side of the acci-
dent.
In an accident with airbag activation:
● the interior lights switch on (if the interior
light switch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked; ●
the fuel supply to the engine is cut.

Airbag system
In the event of a side-on collision, the side
airbag will deploy in the side of the vehicle
affected ››› Fig. 15 , thus reducing the risk of
injurie s
to passengers on the side of the
body and the head facing the accident side. WARNING
The airbag is deployed at high speed in frac-
tions 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 vehicle. Otherwise,
the side airbag would be obstructed when de-
ployed. WARNING
Incorrect handling of the driver's and front
passenger seat could prevent the side airbag
from deploying properly and cause severe in-
juries.
● Never remove the front seats of the vehicle
or modify any of their components.
● Great forces must not be exerted on the
seat backrest bolsters because the side air-
bags 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 special-

Transporting children safely
Transporting children safely Child safety Introduction Before transporting babies and children in a
child 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
correctly secured to avoid severe or fatal inju-
ries while the vehicle is in motion.
● Never use a rear-facing child seat in the
front passenger seat if the front passenger
front airbag is enabled.
● Children up to 12 years old should always
travel on the rear seat. ●
Children 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 properly belted in while trav-
elling.
● Ensure the seat backrest is upright when a
child 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.
● Never hold children or babies on your lap or
in your arms.
● Only one child may occupy a child seat.
● Please read and observe the child seat
manufacturer's handling instructions. WARNING
An empty or loose child seat could fly uncon-
trollably 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, always safely secure the child seat or
store it in the luggage compartment. Note
Replace the child seat after an accident, as it
may have invisible damage. Important information regarding the
