Alw a
ys keep your feet in the footwell when
the vehicle is moving; never rest them on the
dash panel, out the window or on the seat. An
incorrect sitting position exposes you to an
increased risk of injury in case of a sudden
braking or an accident. If the airbag is trig-
gered, you could sustain severe injuries due
to an incorrect sitting position.
● To reduce the risk of injury to the front pas-
senger in ev
ents such as sudden braking ma-
noeuvres or an accident, never travel with the
backrest tilted far back! The airbag system
and seat belts can only provide optimal pro-
tection when the backrest is in an upright po-
sition and the front passenger is wearing his
or her seat belt properly. The further the seat
backrests are tilted to the rear, the greater
the risk of injury due to incorrect positioning
of the belt web or to the incorrect sitting po-
sition!

● Any inc
orrect sitting position increases the
risk of severe injuries. Sitting in an incorrect
position exposes the vehicle occupants to se-
vere injuries if airbags are triggered, by strik-
ing a vehicle occupant who has assumed an
incorrect sitting position.
● Before the vehicle moves, assume the prop-
er sitting po
sition and maintain it throughout
the trip. Before every trip, instruct your pas-
sengers to sit properly and to stay in this po-
sition during the trip ››› page 66, Correct posi-

Drivers with properly worn seat belts
w i
l
l not be thrown forward in the event of sud-
den braking Properly worn seat belts hold the occupants
in the pr
oper po
s

ition. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition,
the front part of your vehicle and other pas-
sive safety features (such as the airbag sys-
tem) are designed to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing around the corner". Ensure that your passengers wear their seat
belts as

well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury
and improving the chances of survival when
involved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!
Safety instructions on using seat
belts –
Always wear the seat belt as described in
thi s
section.
– En

sure that the seat belts can be fastened
at all
times and are not damaged. WARNING
● If se at

belts are worn incorrectly or not at
all, the risk of severe injuries increases. The
optimal protection from seat belts can be
achieved only if you use them properly.
● Fasten your seat belt before every trip -
even when drivin
g in town. Other vehicle oc-
cupants must also wear the seat belts at all
times, otherwise they run the risk of being in-
jured.
● The seat belt cannot offer its full protection
if the seat
belt is not positioned correctly.
● Never allow two passengers (even children)
to shar
e the same seat belt.
● Always keep both feet in the footwell in
front of
your seat as long as the vehicle is in
motion.
● Never unbuckle a seat belt while the vehi-
cle i
s in motion. Risk of fatal injury.
● The seat belt must never be twisted while it
is bein
g worn.
● The seat belt should never lie on hard or
fragil
e objects (such as glasses or pens, etc.)
because this can cause injuries.
● Do not allow the seat belt to be damaged or
jammed, or to rub on an
y sharp edges.
● Never wear the seat belt under the arm or
in any other inc
orrect position.
● Loose, bulky clothing (such as an overcoat
over a j
acket) impairs the proper fit and func-
tion of the seat belts, reducing their capacity
to protect. 72

Safety
WARNING
● Improper u se or r
epairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
inst
all parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic r
etractor cannot be repaired.
● Any work on the belt tensioners and seat
belts, includin
g the removal and refitting of
system parts in conjunction with other repair
work, must be performed by a specialised
workshop only.
● The belt tensioners will only provide pro-
tection for one ac
cident and must be changed
if they have been activated. Airbag system
Brief intr
oduction
Wh

y is it so important to wear a seat
belt and to sit correctly? For the inflating airbags to achieve the best
prot
ection, the se

at belt must always be worn
properly and the correct sitting position must
be assumed.
The airbag system is not a substitute for seat
belts, but it is an integral part of the vehicle's
overall passive safety system. Please bear in
mind that the airbag system can only work ef-
fectively when the vehicle occupants are
wearing their seat belts correctly and have
adjusted the head restraints properly. There-
fore, it is most important to properly wear the
seat belts at all times, not only because this
is required by law in most countries, but also
for your safety ›››
page 71, Why wear a seat
belt?.
The airbag inflates in a matter of seconds, so
if you are not properly seated when the air-
bag is triggered, you may sustain fatal inju-
ries. Therefore, it is essential that all vehicle
occupants assume a correct sitting position
while travelling.
Sharp braking before an accident may cause
a passenger not wearing a seat belt to be
thrown forward into the area of the deploying airbag. In this case, the inflating airbag may
inflict c
ritic

al or fatal injuries on the occu-
pant. This also applies to children.
Always maintain the greatest possible dis-
tance between yourself and the front airbag.
This way, the front airbags can completely
deploy when triggered, providing their maxi-
mum protection.
The most important factors that will trigger
an airbag are: the type of accident, the angle
of collision and the speed of the vehicle.
Whether or not the airbags are triggered de-
pends primarily on the vehicle deceleration
rate resulting from the collision and detected
by the control unit. If the vehicle deceleration
occurring during the collision and measured
by the control unit remains below the speci-
fied reference values, the front, side and/or
curtain airbags will not be triggered. Take in-
to account that the visible damage in a vehi-
cle involved in an accident, no matter how
serious, is not a determining factor for the
airbags to have been triggered. WARNING
● We arin

g the seat belt incorrectly or assum-
ing an incorrect sitting position can lead to
critical or fatal injuries.
● All vehicle occupants, including children,
who are not pr
operly belted can sustain criti-
cal or fatal injuries if the airbag is triggered.
Children up to 12 years old should always 76

Airbag system
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 71.
● Always adjust the front seats properly. Description of the 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 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 66, 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, »

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 18. WARNING
● If you do not wear a seat belt, if you lean
for w

ard, 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 pr
otection, the prescribed sitting78

Airbag system
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

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

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 73. 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.
