X: seat not suitable for securing an ISOFIX or i-Size child seat from this group.
IL-SU: seat suitable for installing an ISOFIX child seat
with semi-universal approval. Take the child seat manu-
facturer's vehicle list into account.
IUF: seat suitable for fixing an ISOFIX child seat with uni-
versal approval.
a) The indication of class according to size corresponds to the
authorised bodyweight for the child seat. In child seats with uni-
versal or semi-universal approval, the class according to size is
indicated on the ECE approval label. The indication of class ac-
cording to size is stated on the corresponding child seat.
Child seats with rigid mounting
For the installation of a child seat with rigid
mounting auxiliary introduction elements can
be used. These elements facilitate fitting and
protect the upholstery. They form part of the
supply volume of the child seat or can be ac-
quired at a SEAT dealership. If necessary,
these elements are inserted in both anchor
points of the vehicle ››› in Safety instruc-
tion s on p

Airbag system
as swelling, bruising and skin injuries can be
ru l
ed out
. Upon deployment of the airbag,
friction can cause the generation of heat.
Airbags do not protect the arms or the lower
part of the body.
The most important factors for triggering the
airbag are the type of accident, the angle of
impact, the vehicle speed and the character-
istics of the object the vehicle hits. Therefore,
airbags are not triggered every time the vehi-
cle is visibly damaged.
The activation of the airbag system depends
on the magnitude of the deceleration of the
vehicle caused by a collision, which registers
through an electronic control unit. If the de-
celeration magnitude value is below the ref-
erence value programmed in the control unit,
the airbags will not deploy even though seri-
ous damage might be caused to the vehicle
as the result of an accident. Damage suffered
by the vehicle, reparation costs or absence of
damage suffered from the accident are not
indications of whether an airbag should have
been deployed. Due to the varying nature of
collision situations, it is impossible to define
a speed range of the vehicle and reference
values. For this reason, it is not possible to
cover all types of collisions and collision an-
gles resulting in the deployment of the air-
bag. Factors necessary for the airbag to be
deployed can be, the characteristics of the
object (hard or soft) against which the vehi- cle collides, the collision angle and the vehi-
cle s
peed.
Airbags act in conjunction with the three-
point seat belts in certain accident situa-
tions, when the vehicle deceleration rate is
severe enough to trigger the airbags. Airbags
only deploy once and only under certain cir-
cumstances. Seat belts remain present to of-
fer protection in situations where airbags are
not triggered or where they have already de-
ployed. For example, when a vehicle hits an-
other after an initial collision or is hit by an-
other vehicle.
The airbag system is an integral part of the
car's passive safety system. The airbag sys-
tem can only work effectively when the vehi-
cle occupants are wearing their seat belts
correctly and have adjusted the head re-
straints properly  ››› page 48. WARNING
Never exclusively trust the airbag system as a
mean s

of protection.
● Even when triggered, airbag protection is
only aux
iliary.
● The airbags provide the best protection
when the seat belt
s are properly fastened,
thus reducing the risk of sustaining injuries
››› page 52, Why wear a set belt .
● Before each trip, every occupant must sit
properly, c
orrectly fasten the seat belt be-
longing to his or her seat and keeping it fas- tened throughout the trip. This rule is valid
for a
l

l vehicle occupants. WARNING
Occupants sitting in the front of the vehicle
mu st

never carry any objects in the deploy-
ment space between them and the airbags,
as this increases the risk of sustaining inju-
ries if the airbag is triggered. This modifies
the airbag deployment space or the objects
may fly uncontrollably and hit your body.
● Never carry objects in your hand or on your
lap whil
e the vehicle is in motion.
● Never transport objects on the front pas-
senger se
at. In the event of sudden braking
and manoeuvres, the objects may end up in
the airbag deployment space and fly uncon-
trollably around the interior if the airbag is
activated.
● Occupants of the front and rear seats must
never carr
y any other people, pets or objects
in the deployment space between them and
the airbags. Make sure children and other
passengers also respect this recommenda-
tion. WARNING
The airbag system provides protection for
one acc ident

only. If they have been de-
ployed, they must be replaced. » 59

Checking and refilling levels
driving. Whenever the ignition is switched
on, the needl e c
h
anges first for a few sec-
onds to the petrol area in order to display the
current level of fuel. The needle then moves
to the natural gas area. After the engine is
started, the needle changes to the area corre-
sponding to the current operating mode.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
su lt

in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply t
o the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack
of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the f
uel tank left to avoid running out of
fuel. CAUTION
● Alw a

ys pay attention to any lit control
lamps and to the corresponding descriptions
and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregu
lar fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

Before refuelling, always turn off the engine,
the ignition, mobile telephones, auxiliary
heating and keep them off during refuelling.
Refuelling
The correct petrol type for the vehicle is loca-
ted on a sticker inside the fuel tank flap
››› page 181.
● If the automatic filler nozzle is operated
correctly
, it will switch itself off as soon as
the fuel tank is full ››› .
● Do not continue to refuel if it is turned off!

se, this will fill the expansion cham-
ber and fuel may leak out if the ambient con-
ditions are warm.
Vehicles with a natural gas engine
Every 6 months it is necessary to run on pet-
rol until the control lamp switches off  and
then the tank must be refilled. This is neces-
sary to ensure the efficient operation of the
system and the fuel quality required for run-
ning on gas. WARNING
Do not continue refilling once the fuel nozzle
ha s

switched itself off. The fuel tank may be
filled too much. As a result, fuel may spurt
out and spill. This could lead to a fire, explo-
sion and severe injuries. » 185
