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

General overview of the airbag Front airbags Fig. 12
Location and deployment area of the
front airbag for the driver. Fig. 13
Location and deployment area of the
front airbag for the passenger. In conjunction with the seat belts, the front
airbag system gives the driver and the front
passenger additional protection for the head
and chest in the event of a severe frontal col-
lision. Always remain as far away as possible
from the front airbag
››› page 6. This way, in
the event of an accident, the front airbags can deploy fully when triggered, providing
maximum protection.
The front airbag for the driver is located in
the steering wheel

f or the fr
ont passenger is located in the dash
panel ››› Fig. 13. Airbags are identified by the
wor

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-
ised workshop. Deactivating airbags

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

Transporting children safely
General information on transporting
children in the vehicle Legal regulations and provisions will always
take priority over the descriptions of this in-
struction manual. There are different regula-
tions and provisions for the use of child seats
and their mountings (
››› table on page 27).
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 11
. However, unlike adults and
y ou
ngsters, children do not have fully devel-
oped muscle 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 systems must be
used that are especially adapted to their
height, weight and constitution. There are
laws in force in many countries that indicate the use of approved seat systems for trans-
porting babies and children.
Only used authorised, approved child seats
that are suitable for the vehicle. Always con-
sult with a SEAT dealership or a Specialised
workshop should you have any doubts.
Specific child seat regulations for each
country (selection)
Child seats must comply with the ECE-R 44
1)
regulation. You can consult additional infor-
mation at your SEAT dealership at the inter-
net address www.seat.es.

Group 215 to 25 kgapprox. 3 to 7 years
Group 322 to 36 kgapprox. 6 to 12 years Not all children fit in the seat of their weight
group. Nor do all seats adapt to the vehicle.
Therefore, always check whether the child fits
properly in the child seat and whether the
seat can be installed safely in the vehicle.
Child seats approved under the ECE-R 44 reg-
ulation are fitted with the corresponding ap-
proval symbol. The sign is an upper-case E in
a circle with the identification number below
it.
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 instal-
led and used on one of the rear seats offer
the most protection possible for babies and
children up to 12 years in most accidents. 1)

cannot disable the front passenger front air-
bag and it remains activated, it is forbidden
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
se

at ››› page 17.
● The seat
backrest of the front passenger
seat must be upright.
● The front passenger seat must be moved as
far back as possible.
● The seat 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 front 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 passen-
ger seat, the risk of the child sustaining se-
vere or fatal injuries in the event of an acci- dent increases. Rear-facing child seats must
never be mounted on the front passenger
seat when the front passenger front airbag is
enabled. This is life-threatening to the child
should the front airbag deploy, as the child
seat would be struck by the inflated airbag
and thrown against the seat backrest.
WARNING
If, in exceptional circumstances, a child must
be transported in a rear-facing child seat on
the front passenger seat, strictly observe the
following:
● Always disable the front passenger front
airbag and leave it disabled.
● The child seat must be approved by the
manufacturer for use on a front passenger
seat with front and side airbag.
● Follow the installation instructions of the
child seat manufacturer and observe the
warnings.
● Move the front passenger seat as far back
as possible and adjust it to its highest posi-
tion to keep as far away as possible from the
front airbag.
● Move the seat backrest to the upright posi-
tion.
● Children must always be protected with an
approved child restraint system suited to
their height and weight. Use of the child seat on the rear seat
If a child seat is mounted on the rear seat,
adapt the position of the front passenger
seat so that the child has enough space.
Therefore, adapt the front passenger seat to
the size of the child seat and the height of
the child. Ensure the passenger is in the cor-
rect position
 ››› page 6.
Suitable child seats
The manufacturer must authorise the child
seat for use in the rear seats with side air-
bags.
Universal seats for children can be fitted in
the passenger seat, in groups 0, 0+, 1, 2 or 3
according to the ECE-R 44 regulation.
The rear seats are suitable for child seats
with the ISOFIX system spec

ially designed
for this type of vehicle in accordance with
regulation ECE-R 44.
ISOFIX child seats approved for rear seats
ISOFIX child seats are divided into the follow-
ing certified categories: “universal”, “semi-
universal” or “specific categories for the ve-
hicle”.
● If the ISOFIX child seat is certified “univer-
sal”, it must be supported by the lower an-
chor points and the Top Tether retaining
