Airbag system
such as the properties of the object the vehi-
c l
e 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
● Knee airbag for the driver.
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.
● Cur

tain (head) airbag on the side of the ac-
cident. In an ac

cident 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 supply to the engine is cut.

Airbag system
●
The side and he a
d airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the
front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
ised workshop. Deactivating airbags

Transporting children safely
Safety for children Introduction For safety reasons, as we have learned from
accident statistics, we recommend that chil-
dren under 12 years of age travel in the rear
seats. Depending on their age, height and
weight, children travelling in rear seats must
use a child seat or a seat belt. For safety rea-
sons, the child seat should be installed in the
rear seat, behind the front passenger seat or
in the centre back seat.
The physical laws involved and the forces
acting in a collision apply also to children
››› page 74 . But unlike adults, children do not
h av

e fully developed muscle and bone struc-
tures. This means that children are subject to
a greater risk of injury.
To reduce the risk of injuries, children must
always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety prod-
ucts from the SEAT Original Accessories Pro-
gramme, which includes systems for all ages
made by “Peke” (not for all countries).
These systems have been especially de-
signed and approved, complying with the
ECE-R44. regulation. »

Safety
Follow the manufacturer's instructions and
o b
ser
ve any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 84.
We recommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.
Important information regarding the
front p
assenger's airbag Read the additional information carefully
› ›
›

 page 20.
Read and always observe the safety informa-
tion included in the following chapters:
● Safety distance with respect to the passen-
ger airbag ›

›› page 77.
● Objects between the passenger and the
pas
senger side airbag ››› in Front airbags
on p ag
e 79
.
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 82.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 85. 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 81. 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 ho l

d children or babies on your lap,
this can 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 to 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 72.
● Only one child may occupy a child seat

Turn signals
The turn signals will flash twice when the ve-
hicle is unlocked and once when the vehicle
is locked.
If it does not flash, this indicates that one of
the doors, the rear lid or the bonnet is not
closed correctly.
Accidental lock-out
The central locking system prevents you from
being locked out of the vehicle in the follow-
