The seat belt may be used to secure univer-
sal type child seats to the vehicle seats
marked with a U in the table below.
If the front passenger seat lacks a height ad-
justment, child seats cannot be mounted is
this location.
To correctly use a child seat in the back, the
front backrest must be adjusted so that there
is no contact with the child seat in the back
in the case that it goes opposite to the direc-
tion of the car. In the case of front facing re-
straint systems, the front backrest must be adjusted so that there is no contact with the
chil

d's feet.
To adjust the passenger seat to accommo-
date a child's seat and get the seat belt in a
perfect position, adjust the passenger back-
rest as far forward as possible.
Starting with Group 0+ child seats should not
be mounted facing backwards in the passen-
ger seat given that due to the size of some of
them, they can be difficult to install.

Two “ISOFIX” retaining rings are fitted on
each rear seat. In some vehicles, the rings
are secured to the seat frame and, in others,
they are secured to the rear floor. The “ISO- FIX” rings are located between the rear seat
back
rest and the seat cushioning. The Top
Tether* rings are located at the rear of the
backrests of the rear seats (behind the seat
backrest or in the boot). To understand the compatibility of the "ISO-
FIX" syst

Number of seats Your vehicle has
five se
ats, two in the front
and three in the rear. Each seat is equipped
with a three-point seat belt.
In some versions, your vehicle is approved
only for four seats. Two front seats and two
rear seats. WARNING
● Never tr an

sport more than the permitted
amount of people in your vehicle.
● Every vehicle occupant must properly fas-
ten and we
ar the seat belt belonging to his or
her seat. Children must be protected with an
appropriate child restraint system. Seat belt lamp* 

When the ignition is switched on, the control
lamp  in the instrument panel lights up (de-
pending on the model version) if the driver or
passenger have not fastened their seat belts.
An audible warning signal will sound for a
few seconds if the seat belts are not fastened
as the vehicle drives off and reaches a speed of more than approximately 25 km/h
(15 mph) or if the seat

belts are unfastened
while the vehicle is in motion. The warning
light will also flash .
The  lamp goes out when the driver and
passenger seat belts are fastened with the ig-
nition switched on.

Depending on the model version, when the
ignition is switched on, the seat belt status
display ››› Fig. 88 on the instrument panel in-
forms the driver whether the passengers in
the rear seats have fastened their seat belts.
The  symbol indicates that the passenger in
this seat has fastened “his or her” seat belt.
When a seat belt in the rear seats is fastened
or unfastened, the seat belt status is dis-
played for approximately 30 seconds. The in-
dication can be hidden by pressing the 0.0/SET button on the dash panel.
The se at

Safety
●
The slot in the se
at belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging se-
curely.
● Never use seat belt clips, fastening rings or
simil
ar items to alter the position of the belt
webbing.
● Frayed or torn seat belts or damage to the
connections, belt
retractors or parts of the
buckle could cause severe injuries in the
event of an accident. Therefore, you must
check the condition of all seat belts at regular
intervals.
● Seat belts which have been worn in an acci-
dent and str
etched must be replaced by a
specialised workshop. Renewal may be nec-
essary even if there is no apparent damage.
The belt anchorage should also be checked.
● Do not attempt to repair a damaged seat
belt y
ourself. The seat belts must not be re-
moved or modified in any way.
● The belts must be kept clean, otherwise the
retract
ors may not work properly. Head-on collisions and the laws of

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 the weight of
the vehicle and its passengers. The higher
they are, the more energy there is to be “ab-
sorbed” in the event of 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.
Given that the passengers of the vehicle in
our example do not have their seat belts fas-
tened, in the event of a collision the entire
amount of the passengers' kinetic energy will
be only absorbed by the mentioned 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 collision are so great that it is not

travel on the rear seat. Never transport
chi
l
dren in the vehicle if they are not restrain-
ed or the restraint system is not appropriate
for their age, size or weight.
● If you are not wearing a seat belt, or if you
lean f
orward or to the side while travelling or
assume an incorrect sitting position, there is
a substantially increased risk of injury. This
increased risk of injury will be further in-
creased if you are struck by an inflating air-
bag.
● To reduce the risk of injury from an inflating
airbag, alw
ays wear the seat belt properly
››› page 72.
● Always adjust the front seats properly. Description of the airbag system
Read the additional information carefully

 page 17.
The airbag system is not a substitute for the
seat belts. The airbag system offers addition-
al protection for the driver and passenger in
combination with the seat belts.
The airbag system comprises the following
modules (as per vehicle equipment):
● Electronic control unit
● Front airbags for driver and passenger
● Knee airbag for the driver
● Side airbags ●
Head airb
ag
● Airbag control lamp  on the instrument
p

anel
● Key-operated switch for front passenger air-
bag
● Contr

ol lamp to disconnect/connect the
front airb
ag.
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp :
● does not light up when the ignition is
switc
hed on,
● turns off after 4 seconds after the ignition
is sw
itched on
● turns off and then lights up again after the
ignition is sw
itched on
● illuminates or flashes while the vehicle is
movin
g.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belt

s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 67, Correct position
for passengers.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise there is a
danger that during a collision, the system
may fail to trigger, or not trigger correctly. 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,

Safety
position must always be maintained with
seat
belt
s fastened while travelling.
● In a side-on collision the side airbags will
not work
if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been remov
ed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels
have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or cov
ered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry
any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to
the doors. This would impair the protection
offered by the side airbags.
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must
not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered. ●
Under no cir c

umstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the se
ams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the side airbag system or re-
mova
l and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.
● Do not attempt to modify components of
the airbag sys
tem in any way. Curtain airbags*

 page 20. WARNING
● In order for the head-protection airbags to
pro v

ide their maximum protection, the pre- scribed sitting position must always be main-
tained w
ith se

at belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disab
led in those vehicles fitted with a
screen dividing the interior of the vehicle.
See your technical service to make this ad-
justment.
● There must be no other persons, animals or
obj
ects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the head-protection airbag
syst
em or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag sys
tem in any way.80

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. »
