The reasons why we should
wear seat belts Number of seats Your vehicle has
five seats, two in the front
and thr ee in the r
ear. 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
r e

ar seats. WARNING
● Never transport more than the permitted
amount of people in your vehicle.
● Every vehicle occupant must properly fas-
ten and wear the seat belt belonging to his or
her seat. Children must be protected with an
appropriate child restraint system. Seat belt warning lamp*

driver to fasten his seat belt.
Before starting the vehicle:
– Fasten your seat belt securely.
– Instruct your passengers to fasten their
seat belts properly before driving off.
– Protect children by using a child seat ac-
cording to the child's height and weight.
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  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 seat belt status flashes for a maximum of
30 seconds when a seat belt in the rear seats
is unfastened while the vehicle is in motion.
An audible warning will also be heard if the
vehicle is travelling at over 25 km/h
(15 mph).

Seat belts
●
The slot in the seat 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
similar 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 stretched 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 yourself. The seat belts must not be re-
moved or modified in any way.
● The belts must be kept clean, otherwise the
retractors may not work properly. Head-on collisions and the laws of
physics
Fig. 62
A driver not wearing a seat belt is
thrown forward violently Fig. 63
The unbelted passenger in the rear
seat is thrown forward violently, hitting the
driver who is wearing a seat belt. It is easy to explain how the laws of physics
work in the case of a head-on collision: when
a vehicle starts moving, a type of energycalled “kinetic energy” is created both in the
passengers 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
children 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 forward 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, always wear the seat belt properly
››› page 43.
● Alw
ays adjust the front seats properly. Description of airbag system
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 airbag ●
Airbag control lamp  on the instrument
panel
● Key-operated switch for front passenger air-
bag
● Control lamp to disconnect/connect the
front airbag.
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
switched on,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
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 belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 38, Sitting position
for vehicle occupants .
● If a fault has occurred in the airbag system,
have the system 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
thousandths 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, »

Airbag system
WARNING
● If you do not wear a seat belt, if you lean
forward, or are not seated correctly while the
vehicle is in motion, you are at a greater risk
of injury if the side airbag system is triggered
in an accident.
● In order for the side airbags to provide their
maximum protection, the prescribed sitting
position must always be maintained with
seat belts 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 removed 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 covered 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 circumstances 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 seams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval 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 system in any way. Head-protection airbags*
Fig. 72
Location of head-protection airbags. The head-protection airbags are located on
both sides in the interior above the doors
››› Fig. 72 and are identified with the text
“AIRB AG”.
In c
onjunction with the seat belts, the head-
protection airbag system gives the vehicle
occupants additional protection for the head
and upper body in the event of a severe side
collision ››› .
WARNING
● In order for the head-protection airbags to
provide their maximum protection, the pre-
scribed sitting position must always be main-
tained with seat belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disabled in those vehicles fitted with a
screen dividing the interior of the vehicle. » 53

●
There must be no other persons, animals or
objects 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; replace them once they have de-
ployed.
● Any work on the head-protection airbag
system 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 system in any way.
● The side and head 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.

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 45 . 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.
