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.

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. 

In conjunction with the seat belts, the front airbag system gives the front
occupants additional protection for the head and chest in the event of a se-
vere frontal collision. Always remain as far away as possible from the front
airbag ⇒ page 48. This way, the front airbags can completely deploy when
triggered, providing their maximum protection. The front airbag for the driver is located in the steering wheel
⇒ Fig. 47 and
the airbag for the front passenger is located in the dash panel ⇒ Fig. 48. Air-
bags are identified by the word “AIRBAG”. 

Child seats (accessories)
Introduction
Before transporting babies and children in a child seat placed in the front
passenger seat, first completely read the information regarding the airbag
system.
This information is extremely important for driver and passenger safety, par-
ticularly that of babies and children.
SEAT recommends the use of child seats from the SEAT accessory pro-
gramme. 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.
Additional information and warnings:
● Seat belts ⇒ page 57
● Airbag system ⇒ page 67
WARNING
Make sure children are properly belted in and correctly secured to avoid
severe or fatal injuries while the vehicle is in motion.
● Never use a rear-facing child seat in the front passenger seat if the
front passenger 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 bel-
ted in while travelling.
WARNING (Continued)
● Ensure the backrest of a seat 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 seat 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 in-
structions.
WARNING
An empty or loose child seat could fly uncontrollably 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 motion, always safely secure it
or store it in the luggage compartment.
Note
Replace the child seat after an accident, as it may have invisible damage. 

General information on transporting children in the vehicle
Legal regulations and provisions will always take priority over the descrip-
tions of this instruction manual. There are different regulations and provi-
sions for the use of child seats and their mountings ( ⇒ table on page 77).
In some countries, for example, the use of child seats on certain seats in the
vehicle may be forbidden.
The physical principles and the forces acting on the vehicle in the event of a
collision or other type of accidents also apply to children ⇒ page 57. Howev-
er, unlike adults and youngsters, children do not have fully developed mus-
cle and bone structures. In the event of an accident, children are subject to
a greater risk than adults of sustaining severe injuries.
Given that children's bodies are not yet fully developed, child restraint sys-
tems must be used that are especially adapted to their height, weight and
constitution. There are laws in force in many countries that determine the
use of approved seat systems for transporting babies and children.
Only used authorised, approved child seats that are suitable for the vehicle.
Always consult with a SEAT dealership or a Specialised workshop should
you have any doubts.
Checklist
To transport children in the vehicle ⇒ 
:
¥ Observe the legal requirements specific to each country.
¥ For safety reasons, SEAT recommends that children under 12 years of
age are transported on the rear seats.
¥ Only if you have no alternative should a child travel on the front pas-
senger seat
⇒ page 79. The safest place in the vehicle is on the
rear seat behind the front passenger seat.
¥ Child must always use a child restraint system when travelling in the
vehicle. The child restraint system must be suitable for the height,
weight and constitution of the child.
¥Only one child may occupy a child seat.
¥ Follow the user instructions from the child seat manufacturer and al-
ways keep them in the vehicle.
¥ If the child seat is secured using the seat belt, guide the seat belt
through or around the child seat according to the instructions of the
child seat manufacturer.
¥ Make sure the seat belt webbing is correctly positioned and that the
child is sitting properly.
¥ The child seat should be installed on the rear seat behind the front
passenger seat so that the child can exit the vehicle on the kerb
side.
¥ Do not leave toys or other loose objects on the child seat or on the
seat while the vehicle is in motion.
Specific child seat regulations for each country (selection)
Child seats must comply with the ECE-R 44

Child seats approved under the ECE-R 44 regulation are fitted with the corre-
sponding approval symbol. The sign is an upper-case E in a circle with the
identification number below it.
WARNING
Not following the checklist prepared for your own safety could lead to ac-
cidents and severe injuries.
● Always follow the check list and perform the necessary operations.
WARNING
In general, the rear seat is always the safest place for children, who are
belted correctly, in the event of an accident.
● A suitable child seat that is correctly installed and used on one of the
rear seats offer the most protection possible for babies and children up
to 12 years in most accidents.
 Different mounting systemsFig. 52 On the rear seats: figure

restraint system mounting using the vehicle's seat belt
Always secure child seats properly and safely in the vehicle according to the
child seat manufacturer's installation instructions.
Mounted child seats must rest correctly on the vehicle's seat and must not
move or rock more than 2.5 cm.
Child seats equipped for a Top Tether strap must also be secured using the
Top Tether retaining strap in the vehicle ⇒ page 83. Only attach the retain-
ing strap to the corresponding retaining rings. Not all rings can be used
with the Top Tether system. Always tighten the Top Tether retaining strap so
that the child seat fits snugly against the corresponding seat in the vehicle. 

Use of the child seat on the front passenger seat
Transporting children on the front passenger seat is not permitted in all
countries. Furthermore, not all child seats are approved for use on the front
passenger seat. Your SEAT dealership has an updated list of all approved
child seats. Only used child seats that are approved for each vehicle.
The frontal airbag on the front passenger side is highly dangerous for a
child. The front passenger seat is life-threatening to a child if he or she is
transported in a rear-facing child seat.
If a rear-facing child seat is secured to the front passenger seat, an inflating
airbag can strike it with such great force that severe or fatal injuries may re-
sult ⇒ 
. Therefore, rear-facing child seats must never be used on the front
passenger seat when the front passenger airbag is enabled.
Only use a rear-facing child seat on the front passenger seat if the front pas-
senger airbag is disabled. When it is disabled, the yellow PASSENGER
AIR BAG   ⇒ page 67 control lamp on the dash panel will be lit. If you
cannot disable the front passenger airbag and it remains enabled, it is for-
bidden to transport children on the front passenger seat ⇒ 
.

Things to note if using a child seat on the front passenger seat:
●
The front passenger front airbag must be disabled  when using a rear-
facing child seat ⇒ page 67.
● The backrest of the front passenger seat must be upright.
● Move the front passenger seat as far back as possible.
● The backrest of the front passenger seat must be upright.
Suitable child seats
The child seat must be authorised by the manufacturer especially for use on
a front passenger seat with a frontal or side airbag.
Universal seats for children can be fitted in the front passenger seat, in
groups 0, 0+, 1, 2 or 3 according to the ECE-R 44 regulation.
WARNING
If a child seat is mounted on the front passenger seat, the risk of the
child sustaining severe or fatal injuries in the event of an accident increa-
ses. Rear-facing child seats must never be mounted on the front passen-
ger seat when the front passenger airbag is enabled. This is life-threaten-
ing to the child should the frontal airbag deploy, as the child seat would
be struck by the inflated airbag and thrown against the backrest.
WARNING
If, in exceptional circumstances, a child must be transported in a rear-fac-
ing child seat on the front passenger seat, strictly observe the following:
● Always disable the front passenger airbag and leave it disabled.
● The child seat must be approved by the manufacturer for use on a
front passenger seat with frontal and side airbag.
● Follow the installation instructions of the child seat manufacturer and
observe the warnings. 
