Safety
frontal collision the system might not trigger
correctly
or m
ay fail to trigger at all.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,
such as the properties of the object the vehi-
cle 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 activ

ates 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
The follo
wing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear s

ide airbag on the side of the acci-
dent.
● Curt

ain (head) airbag on the side of the ac-
cident.
In an acc

ident with airbag activation:
● the interior lights switch on (if the interior
light switc
h is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut. Airbag control lamp and seat belt ten-
sioner  The control lamp monitors all airbags and
seat belt
t

ensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner sys-
tem
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. The control lamp  will light up for a
few seconds every time the ignition is switch-
ed on (self-diagnosis).
The system must be checked when the con-
trol lamp  :
● does not light up when the ignition is
switc hed on,
● t

urns off after 4 seconds after the ignition
is swit
ched on
● turns off and then lights up again after the
ignition is swit
ched on
● illuminates or flashes while the vehicle is
moving.
In the ev

ent of a malfunction, the warning
lamp remains on continuously. Have the air-
bag system inspected immediately by a spe-
cialised workshop.

Intr

fuse a
s

signments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time this
manual was printed. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible. WARNING
The high voltages in the electrical system can
give serious el

ectrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion system. ●
Take c ar

e not to cause short circuits in the
electrical system. WARNING
Using unsuitable fuses, repairing fuses or
bridgin g a curr ent

circuit without fuses can
cause a fire and serious injury.
● Never use a fuse with a higher value. Only
replac
e fuses with a fuse of the same amper-
age (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple
or similar
. CAUTION
● To prev ent

damage to the vehicle's electric
system, before replacing a fuse always turn
off the ignition, the lights and all electrical
elements and remove the key from the igni-
tion.
● If you replace a fuse with higher-rating
fuse, y
ou could cause damage to another part
of the electrical system.
● Protect the fuse boxes when open to pre-
vent the entry
of dust or humidity as they can
damage the electrical system.
● Always carefully remove the fuse box cov-
ers and refit
them correctly to avoid problems
with your vehicle. Note
● One component m a

y have more than one
fuse.
● Several components may run on a single
fuse.
● In the v

ehicle, there are more fuses than
those indicated in thi
s chapter. These should
only be changed by a specialised workshop.
● Positions not containing a fuse do not ap-
pear in the fol
lowing tables.
● Some of the equipment listed in the tables
below pertain on
ly to certain versions of the
model or are optional extras.
● Please note that the above lists, while cor-
rect at the time of
printing, are subject to
change. Fuses to the left of the instrument

are under constant development. SEAT pro-
v ide
s a c
onstant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 190. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
partment, e. g. c

hecking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or cool
ant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● Apply

the handbrake and move the gear
lever to neutr
al or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of b
urns.
● Never spill liquids on a hot engine or on a
hot exhau
st gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal sy
stem, particularly at the points where
the jump leads are attached ›››
 page 52.
The battery could explode. ●
Never touc h the r

adiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulatin
g materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion t
ank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a lar
ge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, suc
h as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must
use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is s
tarted or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before starting any work remove jewellery, tie
back
and c

over hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on el
ectrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sudden ly

open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is pr
operly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not c
orrectly closed then stop immediately
and close it correctly. 202
