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.

 page 22. WARNING
● The deplo yment

space between the front
passengers and the airbags must not in any
case be occupied by other passenger, pets
and objects.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● It is also important not to attach any ob-
jects
such as cup holders or telephone
mountings to the surfaces covering the air-
bag units.
● Do not attempt to modify components of
the airbag sys
tem in any way. Knee airbag*

● The knee airbag i s

deployed in front of the
driver's knees. Always keep the deployment
areas of the knee airbags free.
● Never not fix objects to the cover or in the
deployment
area of the knee airbag.
● Adjust the driver's seat so that there is a
dist
ance of at least 10 cm (4 inches) between
your knees and the location of the this air-
bag. If your physical constitution prevents
you from meeting these requirements, make
sure you contact a specialised workshop. Side airbags*

Transporting children safely
Transporting children safely Saf ety
f
or children
Introduction For safety reasons, as we have learned from
acc
ident

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 82. But unlike adults, children do not
have 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. Follow the manufacturer's instructions and
ob
ser

ve any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 91.
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 25.
Read and always observe the safety informa-
tion included in the following chapters:
● Safety distance with respect to the passen-
ger airbag ›

›› page 85.
● Objects between the passenger and the
pas
senger side airbag ››› in Front airbags
on p ag
e 87
.
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 89.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 92. 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 90. 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. » 91
