Child seats with rigid mounting
For the installation of a child seat with rigid
mounting auxiliary introduction elements can
be used. These elements facilitate fitting and
protect the upholstery. They form part of the
supply volume of the child seat or can be ac-
quired at a SEAT dealership. If necessary,
these elements are inserted in both anchor
points of the vehicle ››› in Safety instruc-

Safety
of severe or fatal injuries is especially height-
ened when a dep lo
y
ing airbag strikes a vehi-
cle occupant who has assumed an incorrect
sitting position. The driver is responsible for
all passengers in the vehicle, particularly
children.
The following list shows just some examples
of incorrect sitting positions which can be
dangerous to all vehicle occupants.
When the vehicle is in motion:
● Never stand in the vehicle.
● Never stand on the seats.
● Never kneel on the seats.
● Never tilt your seat backrest too far to the
rear
.
● Never lean against the dash panel.
● Never lie on the rear seats.
● Never sit on the front edge of a seat.
● Never sit sideways.
● Never lean out of a window.
● Never put your feet out of a window.
● Never put your feet on the dash panel.
● Never put your feet on the surface of a seat
or seat b
ackrest.
● Never travel in a footwell.
● Never travel on a seat without wearing the
seat belt
. ●
Never carr
y any person in the luggage com-
partment. WARNING
An incorrect sitting position in the vehicle
can l e

ad to severe injuries or death in the
event of sudden braking or manoeuvres, colli-
sion or accidents or if the airbag deploys.
● Before the vehicle moves, assume the prop-
er sitting po
sition and maintain it throughout
the trip. This also includes fastening the seat
belt.
● Never transport more people than there are
seats
with a seat belt available in the vehicle.
● Children must always be protected with an
appro
ved child restraint system suited to
their height and weight ››› page 64,
››› page 58.
● Always keep your feet in the footwell while
the vehic
le is in motion. Never, for example,
put your feet on the surface of a seat or on
the dash panel and never put them out of a
window. Otherwise the airbag and seat belt
offer insufficient protection and the risk of in-
jury in the event of an accident is increased. WARNING
Before every trip, adjust the seat, the seat
belt and the he a

d restraints and instruct your
passengers to fasten their seat belts proper-
ly.
● Move the front passenger seat back as far
as po
ssible. ●
Adjus t

the driver seat so that there is at
least 25 cm distance between your chest and
the hub of the steering wheel. Adjust the
driver seat so that you are able to press the
accelerator, brake and clutch pedals to the
floor with your knees slightly angled and that
the distance between your knees and the
dash panel is at least 10 cm. If your physical
constitution prevents you from meeting these
requirements, contact a specialised work-
shop to make any modifications required.
● Never drive with the seat backrest tilted far
back.
The further the seat backrests are tilted
to the rear, the greater the risk of injury due
to incorrect positioning of the belt web or to
the incorrect sitting position!
● Never drive with the seat backrest tilted
forw
ards. Should a front airbag deploy, it
could throw the seat backrest backwards and
injure the passengers of the rear seats.
● Sit as far away as possible from the steer-
ing wheel and the d
ash panel.
● Keep your back straight and resting com-
plet
ely against the seat backrest and the
front seats correctly adjusted. Never place
any part of your body in the area of the airbag
or very close to it.
● If passengers on the rear seats are not sit-
ting in an upright po
sition, the risk of severe
injury due to incorrect positioning of the belt
web increases. 50

Safety
In the event of failure of a brake circuit, the
br ak
e ped
al must be pressed harder than
normal to brake the vehicle. WARNING
Objects falling into the driver's footwell could
prev ent

use of the pedals. This could lead the
driver to lose control of the vehicle, increas-
ing the risk of a serious accident.
● Make sure the pedals can be used at all
times, with no o
bjects rolling underneath
them.
● Always secure the mat in the footwell.
● Never place other mats or rugs on top of
the original
mat supplied by the factory.
● Ensure that no objects can fall into the driv-
er's footw
ell while the vehicle is in motion. CAUTION
The pedals must always have free and unob-
struct ed p

assage to the floor. For example, in
case of a fault in the brake circuit, the brake
pedal will need to be pressed further to stop
the vehicle. To press the brake pedal down
further will require more force than usual. Seat belts
Wh y
w

ear a set belt
Introduction Check the condition of all the seat belts at
re
gu

lar 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 spe-
cialised workshop ››› . The specialised
w ork
shop mu

st use the appropriate spare
parts corresponding to the vehicle, the
equipment and the model year. SEAT recom-
mends taking your car in for technical serv-
ice. WARNING
Unbuckled or badly buckled seat belts in-
cr e

ase the risk of severe or even fatal inju-
ries. The seat belt cannot offer its full protec-
tion if it is not fastened and used correctly.
● Seat belts are the most effective way of re-
ducing the ri
sk of sustaining severe or fatal
injuries in the event of an accident. Seat belts
must be correctly fastened when the vehicle
is in motion to protect the driver and all vehi-
cle occupants.
● Before each trip, every occupant in the ve-
hicle oc
cupants 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 vehicle occupants
when drivin
g in t

own.
● When travelling, children must be secured
in the vehic
le with a child restraint system
suitable for their weight and height and with
the seat belts correctly fastened
››› page 64.
● Instruct your passengers to fasten their
seat belt
s properly before driving off.
● Insert the latch plate into the buckle for the
appropri
ate seat and ensure 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 en-
ter the buc
kle fastenings. This could damage
the buckles and seat belts.
● Never unbuckle your seat belt when the ve-
hicle i
s moving.
● Never allow more than one passenger to
share the s
ame seat belt.
● Never hold children or babies on your lap
sharing the s
ame seat belt.
● Bulky and unbuttoned clothing, such as a
coat
worn over a sweatshirt, impairs the
proper fit and function of the seat belt. WARNING
It is extremely dangerous to drive using dam-
aged se at

belts and could result in serious in-
jury or loss of life. 52

Seat belts
Head-on collisions and the laws of
ph y
s
ics Fig. 70
A driver not wearing a seat belt is
thr o
wn f

orward violently. Fig. 71
The unbelted passenger in the rear

i

s thrown forward violently, hitting the
driver who is wearing a seat belt. It is easy to explain how the laws of physics
w
ork
in the c

ase of a head-on collision: when
a vehicle starts moving, a type of energy called “kinetic energy” is created both in the
pas

sengers and inside the vehicle.
The amount of “kinetic energy” depends on
the speed of the vehicle and on the weight of
the vehicle and of its passengers. The higher
the speed and the greater the weight, the
more energy there is to be “absorbed” in an
accident.
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h
(30 mph), for example, the corresponding ki-
netic energy is multiplied by four.
Because the vehicle occupants in our exam-
ple are not restrained by seat belts, in the
event of crashing against a wall, all of the oc-
cupants' kinetic energy will be absorbed
solely by said impact.
Even at speeds of 30 km/h (19 mph) to
50 km/h (30 mph), the forces acting on bod-
ies in a collision can easily exceed one tonne
(1000 kg). At greater speed these forces are
even higher.
Vehicle occupants not wearing seat belts are
not “attached” to the vehicle. In a head-on
collision, they will move forward at the same
speed their vehicle was travelling just before
the impact. This example applies not only to
head-on collisions, but to all accidents and
collisions. Even at low speeds the forces acting on the
body in a co
llision are so great that it is not
possible to brace oneself with one's hands.
In a frontal collision, unbelted passengers
are thrown forward and will make violent con-
tact with the steering wheel, dash panel,
windscreen or whatever else is in the way
››› Fig. 70.
It is also important for rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-
danger not only themselves but also the front
occupants ››› Fig. 71.

Transporting children safely Saf ety
f
or children
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

Read and always observe the safety informa-
tion included in the following chapters: ● Safety distance with respect to the passen-
ger airbag ›

›› in Introduction on page 59.
● Objects between the passenger and the
pa s

senger side airbag ››› in Front airbags
on p ag
e 61
.
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 ›››
page 63.
When transporting children, use a child seat
suitable for the age and size of each child

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 67).
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 52. However, unlike adults and
youngsters, 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-
portin
g b

abies 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 coun-
try (selection)
Child seats must comply with the ECE-R 44 1)
regulation. You can get additional informa-
tion by consulting your SEAT dealership or at
the internet address www.seat.es. Categorisation of child seats according to

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-

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 specially 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 c

hild seat is certified “univer-
sal”, it must be supported by the lower an-
chor points and the Top Tether retaining
strap.
● If the ISOFIX child seat is certified “semi-
univer
sal” or “specific categories for the ve-
hicle”, check that the child seat is certified
for the vehicle before employing it. The child
seat manufacturer supplies, in addition to
the ISOFIX child seat, a list of vehicles for
which the corresponding ISOFIX child seat
has been certified. If necessary, contact the
child seat manufacturer for an updated list of
vehicles.

Do not c lo

se the rear lid by pushing it down
with your hand on the rear window. This
could break and cause injury.
● Ensure the rear lid is locked after closing,
otherwi
se, it may open unexpectedly while
driving. A closed rear lid should be flush with
the corresponding parts of the bodywork.
● Always keep the rear lid closed while driv-
ing to av
oid toxic gases entering the vehicle
interior.
● Do not open the rear lid when there is a
load in
stalled, for example a carrier system.
Likewise, the boot hatch cannot be opened
when a load is attached to it, for example bi-
cycles. An open rear lid could close itself if
there is an additional weight on it. If necessa-
ry, press down on the rear lid and remove the
load.
● Close and lock both the rear lid and all the
other doors when
you are not using the vehi-
cle. Ensure that nobody remains inside the
vehicle.
● Never allow children to play inside or
around the
vehicle without supervision, espe-
cially if the rear lid is open. Children could
enter the luggage compartment, close the
rear lid and become trapped. Depending on
the time of the year, temperatures inside a
locked and closed vehicle can be extremely
high or extremely low resulting in serious in-
juries and illness or even death, particularly
for young children.

WARNING
Unsecured or incorrectly secured objects can
cau se seriou

s injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are
struck by a detonating airbag and fired
through the vehicle interior. To reduce the
risks, please note the following:
● Secure all objects in the vehicle. Always
keep equipment and he
avy objects in the lug-
gage compartment.
● Always secure objects with suitable rope or
sling
s so that they cannot enter the deploy-
ment areas around the frontal or side airbags
in case of sudden braking or an accident.
● Always ensure that objects inside the vehi-
cle c
annot move into the deployment area of
the bags while driving. ●
Whil e driv

ing, always keep object compart-
ments closed.
● Remove all objects from the front passen-
ger seat
when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat i
s folded, the frontal airbag must remain
disconnected and the PASSENGER AIRBAG
OFF  light on.
● Objects secured in the vehicle should never
be plac
