 page 8 Central locking functions correctly when all
the doors and the r

ear lid are correctly shut.
If the driver door is open, the vehicle cannot
be locked with the key.
The battery of an unlocked vehicle parked for
a long period (e.g. in a private garage) may
run down and fail to start the motor. WARNING
The incorrect use of the central locking sys-
tem m a

y cause serious injuries.
● The central locking system will lock all
doors. A v
ehicle locked from the inside can
prevent any non-authorised individual from
opening the doors and accessing the vehicle.
Nevertheless, in case of emergency or acci-
dent, locked doors will complicate access to
the vehicle interior to help the passengers.
● Never leave children or disabled people
alone in the v
ehicle. The central locking but-
ton can be used to lock all the doors from
within. Therefore, passengers will be locked
inside the vehicle. Individuals locked in the
vehicle can be exposed to very high or very
low temperatures.
● Depending on the time of the year, temper-
ature
s inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children.
● Never leave individuals locked in a closed
and locked
vehicle. In case of emergency,
they may not be able to exit the vehicle by
themselves or get help. 94

electronic parking brake, activate the selec-
tor lever or gear stick and start the vehicle
moving. This could result in a serious acci-
dent.
● Always take all the keys with you whenever
you le
ave the vehicle. The engine could acci-
dentally be started and electrical equipment
such as the windows could accidentally be
operated resulting in serious injury.
● Never leave children or disabled people
alone in the car
. They could be trapped in the
car in an emergency and will not be able to
get themselves to safety. For example, de-
pending on the time of the year, tempera-
tures inside a locked and closed vehicle can
be extremely high or extremely low resulting
in serious injuries and illness or even death,
particularly for young children. CAUTION
● Spec i

al care should be taken when parking
in areas with high kerbs or fixed barriers. Ob-
jects protruding from the ground may dam- age the bumper or other parts of the vehicle
during m
anoeu

vres. To avoid damage, stop
before the wheels touch the barrier or kerb.
● Special attention is required when driving
through entranc
es, over ramps, kerbs or oth-
er objects. The vehicle underbody, bumpers,
mudguards and running gear, and the engine
and exhaust system could be damaged as

Advice
WARNING
The high voltages of the electrical system can
give el ectric
shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
syst
em. The battery could explode.
● To minimise the risk of electric shock and
serious c
onsequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system. WARNING
In the engine compartment, there are rotat-
ing p ar

ts that could cause serious injury.
● Never place your hands directly on or near
the radi
ator fan. Touching the rotor blades
could seriously harm you. The ventilator
works according to the engine temperature
and could start suddenly even when the igni-
tion is turned off and the key is removed.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from rotating parts, such as the drive
belts, alternator, radiator fan, etc., as well as
from the high-voltage ignition system. Al-
ways work with the utmost caution.
– Always make sure that no parts of your
body, jewellery, ties, loose clothing and
long hair can be trapped by the rotating
parts of the engine. Before any work, re- move ties and jewellery (necklaces, etc),
tie long h
air b

ack and tie all items of
loose clothing to your body to make sure
that they cannot be trapped by engine
components.
– Take extreme caution when operating the
accelerator and remain attentive. The ve-
hicle could move, even if the handbrake
is applied.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths and tools, in
the engine compartment. If any object is left
in the engine compartment, this could cause
malfunctions, engine faults and even a fire. WARNING
Refill liquids and certain materials can catch
fire e a

sily in the engine compartment, caus-
ing a fire and serious injury!
● Never smoke.
● Never work close to places exposed to
flames
or sparks.
● Never pour service fluids over the engine.
These fluid ma
y ignite hot engine parts and
cause injuries.
● If it is necessary to work on the fuel system
or the electrica
l system, please follow the in-
structions below:
–Always disconnect the vehicle battery.
– Never work close to heaters, heat sources
or places exposed to flames or sparks. ●
Alw a

ys keep a recently serviced and per-
fectly working fire extinguisher close by.
● Never cover the engine with additional in-
sul
ating materials such as a blanket. Risk of
fire! WARNING
If the bonnet is not correctly closed, it could
s ud den

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
properly 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
correctly closed then stop immediately
and close it correctly.
● Make sure the bonnet is opened and closed
safely
(when the engine is off, no smoke is
coming from the engine compartment, there
is enough space around the car, no people
are near, etc.). CAUTION
● When refi l

ling or changing service liquids,
ensure that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! 188

Advice
● Chec k
ther
e is enough water in the reser-
voir.
● To top up, mix water with a window cleaner
recommended b
y SEAT ››› . Please follow
the in s
truction
s for use found on the packag-
ing.
● In cold weather, a special antifreeze should
also be ad
ded to prevent the water from
freezing.
Reservoir capacity
The washer bottle capacity is approximately 3
litres. WARNING
If the water from the windscreen washer does
not c ont

ain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contain
s enough anti-freeze.
● In cold conditions, you should not use the
winds
creen wiper system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
simi l

ar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility. ●
Use c l

ean water with a window cleaner rec-
ommended by SEAT.
● If necessary, add a suitable antifreeze to
the water in the r
eservoir. CAUTION
● Do not mix

cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage! Vehicle battery
