 page 17
Before starting any work on the engine or in
the engine compartment:
1. Switch off the engine and remove the key from the ignition.
2. Ap

ply the handbrake.
3. Move the gear lever to neutral or the selec- tor lev
er to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ›››

page 274.
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant 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 259. The engine compart-
ment of the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
par tment, e.

g. checking 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 coo
lant 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.
● App

ly the handbrake and move the gear
lever t
o neutral or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of
burns.
● Never spill liquids on a hot engine or on a
hot exh
aust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal
system, particularly at the points where
the jump leads are attached ›››
 page 72.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition! ●
Never c o

ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank 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 l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t 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
started 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 cover hair, and wear tight-fit-
ting clothes. » 273

Checking and refilling levels
If the warning lamp flashes although the oil
l ev
el
is correct, stop driving. Do not even run
the engine at idle speed! Obtain technical as-
sistance.
Checking oil level
If the warning lamp is yellow  the engine
oil level should be checked as soon as possi-
ble. Top up the oil at the next opportunity
››› page 277.
Oil level sensor faulty*
If the  yellow warning lamp flashes, take
the vehicle to a specialised workshop to have
the oil level sensor checked. Until then it is
advisable to check the oil level every time
you refuel.
Checking engine oil level Fig. 238

 page 58
Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until
the operating t

emperature is reached and
then stop.
– Wait for about two minutes.
– Pull out the dipstick. Wipe the dipstick with
a cle

an cloth and insert it again, pushing it
in as far as it will go.
– Then pull it out again and check the oil lev-
el. T

op up with engine oil if necessary.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney. WARNING
Any work carried out in the engine compart-
ment or on the en gine mu

st be carried out
cautiously.
● When working in the engine compartment,
alwa
ys observe the safety warnings

Checking and refilling levels
●
Never open the bonnet if
you can see or
hear steam 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. B
efore 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 273. Topping up coolant
Read the additional information carefully
› ›
›

 page 59
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-
pans

ion tank. 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. –
Cov
er the coolant expansion tank cap with
a cloth and carefully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the e
xp

ansion 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 to the upper mark.
– Top up with coolant until the level becomes
stab

le.
– Screw the cap back on correctly.
Any lo
ss 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 coo lin

g system 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 h
azard. Therefore, the antifreeze
should be stored in the original container in a safe place out of reach of children. Failure to
comp
ly

could result in poisoning.
● If working inside the engine compartment,
remember that, ev
en when the ignition is
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

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is 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 cool
ant 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. CAUTION
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. » 279

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
ut is, for example, brown, this indicates
that the G13 additive has been mixed with an
inadequate coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and

automatically adjusted as they wear.
However, if the level goes down noticeably in
a short time, or drops below the “MIN” mark,
there may be a leak in the brake system. A
display on the instrument panel will warn you
if the brake fluid level is too low ››› page 121. WARNING
Before opening the bonnet to check the brake

We recommend that you have the brake fluid
changed by a Technical Service.
Before opening the bonnet, please read and
follow the warnings ››› in Safety notes for
w ork
in the en

gine compartment on
page 273 in section “Safety notes for work-
ing in the engine compartment”.
In the course of time, brake fluid becomes
hygroscopic and absorbs water from the am-
bient air. If the water content in the brake flu-
id is too high, the brake system could cor-
rode. This also considerably reduces the boil-
ing point of the brake fluid. Heavy use of the brakes may then cause a vapour lock which
coul

d impair the braking effect.
Be sure to always use the correct brake fluid.
Only use brake fluid that expressly meets the
VW 501 14 standard.
You can buy VW 501 14 standard brake fluid
in a SEAT dealership or a SEAT Official Serv-
ice. If none is available, use only high-quality
brake fluid that meets DIN ISO 4925 CLASS 4
standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one
that is not of a high quality may affect opera-
tion of the brake system and reduce its effec-
tiveness. Never use a brake fluid if the con-
tainer does not state that it complies with VW
501 14, DIN ISO 4925 CLASS 4 standards, or
USA standards FMVSS 116 DOT 4. WARNING
Brake fluid is poisonous. Old brake fluid im-
pair s

● Before opening the bonnet to check the
brake fluid l
evel, read and observe the warn-
ings ››› page 273.
● Brake fluid should be stored in the closed
original
container in a safe place out of reach
of children. There is a toxic risk.
● Perform the brake fluid change according to
the Mainten
ance Programme. Heavy use of
the brakes may cause a vapour lock if the
brake fluid is left in the brake system for too 280
