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

Checking and refilling levels
WARNING
Oil is highly inflammable! Ensure that no oil
comes int
o contact with hot engine compo-
nents when topping up. CAUTION
If the oil level is above the area A do not
star t

the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop. For the sake of the environment
The oil level must never be above area A .
Otherwi se oi

l can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. Changing engine oil

The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme. WARNING
Only change the engine oil yourself if you
have the s pec

ialist knowledge required!
● Before opening the bonnet, read and ob-
serve the warnin
gs ››› page 201, safety notes
for work in the engine compartment .
● Wait for the engine to cool down. Hot oil
may c
ause burn injuries.
● Wear eye protection to avoid injuries, such
as acid b
urns, caused by splashes of oil.
● When removing the oil drain plug with your
fingers, k
eep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact w
ith engine oil.
● Engine oil is poisonous! Used oil must be
stored in a s
afe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This c ou

ld result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Becau se of

disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service. ●
Never pour oil do

wn drains or into the
ground.
● Use a suitable container when draining the
used oil. It
must be large enough to hold all
the engine oil. Cooling system
Contro l

lamp There is a fault if:
● The  l amp does not go out again after a
f ew sec ond

s.
● The  lamp lights up or flashes while the
vehicl
e is running, and three acoustic warn-
ing signals are emitted ››› .
Thi s
me an

s that either the coolant level is too
low or the coolant temperature is too high.
Coolant temperature too high
If the  lamp lights up, stop the vehicle,
turn off the engine and wait for it to cool
down. Check the coolant level.
If the coolant level is correct, the overheating
may be caused by a malfunction of the radia-
tor fan. Check the radiator fan fuse and have
it replaced if necessary ››› page 81.
If the control lamp lights up again after driv-
ing on for a short distance, stop the vehicle»

Coolant level too low
If the  lamp lights up, stop the vehicle,
turn off the engine and wait for it to cool
down. First check the coolant level. If the lev-
el of the coolant is below the “MIN” mark,
top up with coolant liquid ››› .
WARNING
● If y our

vehicle is immobilised for technical
reasons, move it to a safe distance from traf-
fic. Turn the engine off, turn the hazard lights
on and place the warning triangle.
● Never open the bonnet if you can see or
hear ste
am or coolant escaping from the en-
gine compartment. Risk of scalding. Wait un-
til you can no longer see or hear escaping
steam or coolant.
● The engine compartment is a dangerous
area. Bef
ore carrying out any work in the en-
gine compartment, switch off the engine and
allow it to cool down. Always note the corre-
sponding warnings ››› page 201. Topping up coolant

Top up coolant when the level is below the
MIN (minimum) mark. Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pansion t

ank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant – Wait for the engine to cool down.
– Cover the coolant expansion tank cap with
a cloth and caref

ully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the e
xpan

sion tank, otherwise you
could damage the engine. If there is no
coolant in the expansion tank, do not con-
tinue driving. You should obtain professio- nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t op up t

o the upper mark.
– Top up with coolant until the level becomes
stabl

e.
– Screw the cap back on correctly.
Any los
s of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no leaks in the engine cooling system, a loss of
coolant

can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coolin g sy

stem is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health haz
ard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● If working inside the engine compartment,
remember that, even when the ignition i
s
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury. WARNING
If there is not enough anti-freeze in the cool-
ant sys t

em, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive i
s correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant
could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. 208
