Airbag system
WARNING
● The seat belt
s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 48.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. 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,
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 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.
In an acc

ident 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 s
upply to the engine is cut.

the following rules to minimise the risk of in-
jury:
● Stop the vehicle safely as soon as possible.
Park at
a safe distance from surrounding traf-
fic to change a wheel.
● When changing a wheel, keep all passen-
gers, and p
articularly children, a safe dis-
tance away from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Ensure the ground on which you park is flat
and solid. If nec
essary, support the jack on a
wide solid base.
● If you are changing a wheel yourself, you
should be f
amiliar with the required proce-
dure. Otherwise, you should seek professio-
nal assistance.
● Only use suitable tools that are not dam-
aged when ch
anging a wheel.
● Always stop the engine, apply the hand-
brake l
ever firmly and place the selector lever
in position N, or engage a gear for a manual gearbox to reduce the risk of the vehicle mov-
ing ac

Self-help
The Anti-puncture kit* (Tyre Mobility System)
w i
l
l reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
jects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tyre mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.
Do not use the tyre sealant in the following
cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F).
● In the event of cuts or perforations in the
tyre gr
eater than 4 mm.
● If you have been driving with very low pres-
sure or a c
ompletely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
ger ou

s, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury: ●
Stop the v

ehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid.
● Al

l passengers and particularly children
must
keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other roa
d users.
● Use the tyre mobility system only if you are
famili
ar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary
emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tyre mo-
bility
set as soon as possible.
● The sealant is a health hazard and must be
cle
aned immediately if it comes into contact
with the skin.
● Always keep the tyre mobility set out of the
reac
h of small children.
● Never use an equivalent jack, even if it has
been appro
ved for your vehicle.
● Always stop the engine, apply the hand-
brake l
ever firmly and engage gear if using a
manual gearbox, in order to reduce the risk of
vehicle involuntary movement. WARNING
A tyre filled with sealant does not have the
same per f

ormance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fas
t cornering.
● Drive for only 10 minutes at a maximum
speed of 80
km/h (50 mph) and then check
the tyre. For the sake of the environment
Dispose of used or expired sealant observing
any l

egal requirements. Note
● A new bottle of se

alant can be purchased at
SEAT dealerships.

As the driv er of

the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and
brake gently. CAUTION
● When t ow-

starting, fuel could enter the cat-
alytic converter and damage it.
● Carefully fit and remove the towline anchor-
age and its
cover to avoid damage to the ve-
hicle (e.g. paintwork).
● When towing, fuel could enter the catalytic
conv
erter and cause damage! Note

llowing for a towed vehicle:
● Make sure the gear selector lever is in the N
position.
● Do not

drive faster than 50 km/h (30 mph)
when tow
ing a vehicle.
● Do not tow further than 50 km (30 miles). ●
If a bre
akdown truck is used, the vehicle
must be towed with the front wheels raised.
Situations in which a vehicle should not be
towed
In the following cases, the vehicle should not
be towed but transported on a trailer or spe-
cial vehicle:
● If the vehicle gearbox does not contain lu-
bricant due t
o a fault.
● If the battery is flat and the steering cannot
be unloc
ked as a result, the electronic steer-
ing lock and electronic parking brake cannot
be disengaged.
● If the vehicle to be towed has an automatic
gearbo
x and the distance to be covered is
greater than 50 km (30 miles). Note
The vehicle can only be towed if the steering
lock el

ectronic gearbox lock is deactivated. If
the vehicle has no power supply or there is
an electric system fault, the engine must be
started using jump leads to deactivate the
steering column electronic gearbox lock. 76

Introduction Due to the constant updating of vehicles,
fu
se a

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 of
printing this manual. 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 seriou s

electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion syst
em. ●

are 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
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.
● Protect the fuse boxes when open to pre-
vent the entr
y of dust or humidity as they can
damage the electrical system. Note
● One component m

ay have more than one
fuse. 78

sk

ill. If you are unsure, SEAT recom-
mends that you consult a technical service or
request assistance from a specialist. In gen-
eral a specialist is needed if, in addition to
the bulbs, other vehicle components require
removal.
You should store spare light bulbs in the ve-
hicle for safety-relevant lights. Spare bulbs
may be obtained from the technical services.
In some countries, it is a legal requirement to
carry spare bulbs in the vehicle.
