Airbag system
frontal collision the system might not trigger
corr
ectly
or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thous
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,
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-
tor
y

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
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. Airbag and seat belt tensioner control
lamp  The control lamp monitors all airbags and
seat
belt

tensioners 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. Each time the ignition is switched on,
the control lamp  illuminates for several
seconds (self-diagnosis) and the instrument
panel display* shows AIRBAG/TENSIONER.
The system must be checked when the con-
trol lamp  :
● does not light up when the ignition is
swit c

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.
In the event of a malfunction, the warning
lamp stays on continuously. In addition, de-
pending on the malfunction, a fault message
appears on the instrument panel display for
approximately 10 seconds and a short audi-
ble warning is given. In this event, you »

To tighten the towline anchorage, we recom-
mend using the box spanner, the towing eye
from another vehicle or a similar object that
can be inserted through the anchorage.
– Unscrew the towline anchorage by turning
it cloc

kwise. CAUTION
The towline anchorage must be screwed in as

it will go. Otherwise there is a risk of
the screw connection shearing off during

Introduction Due to the constant updating of vehicles,

ssignments 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.
Additional information and warnings:
● Working in the engine compartment

page 204. WARNING
The high voltages in the electrical system can
give seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em.
● Take care not to cause short circuits in the
electrica
l system. WARNING
Using unsuitable fuses, repairing fuses or
bridging a c urr

ent circuit without fuses can
cause a fire and serious injury.
● Never use a fuse with a higher value. Only
repl
ace 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 simil
ar. CAUTION
● To pr ev

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,
you could cause damage to another part
of the electrical system. » 81

Checking and refilling levels
●
When work in
g underneath the vehicle, se-
cure it so that it cannot roll away and support
it safely on suitable supports. The hydraulic
jack is not sufficient for this purpose. Risk of
injuries!
● If any tests have to be performed with the
engine runnin
g, there is an extra safety risk
from rotating parts, such as the drive belt, al-
ternator and radiator fan, etc., and from the
high-voltage ignition system. You should also
note the following:
– Never touch the electrical wiring of the
ignition system.
– Keep away from moving engine parts
when wearing jewellery, loose clothing or
long hair. Risk of fatal injuries! All jewel- lery must be removed, hair tied back and
close-fitting clothing worn.
● Observe the following additional warnings
if work
on the fuel system or the electrical
system is necessary.
–Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
● When top pin

g up fluids, make sure the cor-
rect fluid is put into the correct filler opening. Otherwise this can cause serious malfunc-
tions
or en

gine damage!
● Never open the bonnet using the release
catc
h. Risk of damage! For the sake of the environment
Due to the environmentally-friendly disposal
of fluid s, the equipment

necessary and the
knowledge required, let an authorised SEAT
dealer change fluids during service inspec-
tions of the vehicle. Note
● Ple a

se contact an authorised SEAT dealer
with any doubts regarding fluids.
● Fluids of the correct specifications can be
acquired fr
om the selection of SEAT Original
Accessories. Opening and closing the bonnet
