Airbag system
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.
The following airbags are triggered in seri-
ous head-on collisions ● Driver airbag.
● Front passenger front airbag
The fol
lowing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Re

ar side airbag on the side of the acci-
dent.
In an acc

ident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked; ●
the fuel s
upply to the engine is cut.

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

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

Suitable child seats
The manufacturer must authorise the child
seat for use in the rear seats with side air-

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

penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
jects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tyre mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F).
● In the event of cuts or perforations in the
tyre gr
eater than 4 mm.
● If you have been driving with very low pres-
sure or a c
ompletely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
ger ou

s, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury: ●
Stop the v

ehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid.
● Al

l passengers and particularly children
must
keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Use the tyre mobility system only if you are
famili
ar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary
emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tyre mo-
bility
set as soon as possible.
● The sealant is a health hazard and must be
cle
aned immediately if it comes into contact
with the skin.
● Always keep the tyre mobility set out of the
reac
h of small children.
● Never use an equivalent jack, even if it has
been appro
ved for your vehicle.
● Always stop the engine, apply the hand-
brake l
ever firmly and engage gear if using a
manual gearbox, in order to reduce the risk of
vehicle involuntary movement. WARNING
A tyre filled with sealant does not have the
same per f

ormance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fas
t cornering.
● Drive for only 10 minutes at a maximum
speed of 80
km/h (50 mph) and then check
the tyre. For the sake of the environment
