pec

ifications.
The correct oil must be used to ensure the
correct operation and long service life of the
engine. The engine comes with a high-quality
multigrade oil that can generally be used all
year round.
Only use an engine oil that complies to SEAT
standards whenever possible ››› . Only refill
en gine oi l

using approved engine oil in ac-
cordance with the corresponding VW stand- ard (
››› table on page 187). All oils indicated
ar
e synthetic multigrade oils .
Engine oils are being continuously further
developed. Technical services are constantly
updated with any modifications. SEAT there-
fore recommends that you have the engine
oil changed by a technical service.

Preparations
● Park the vehicle on flat ground so that the
en gine oi
l
reading is correct.
● The engine must be hot to be able to check
the engine oil
level. Stop the engine and wait
a few minutes for the oil to drain back into
the sump.
● Open the bonnet  ›››
page 184.
● The engine oil filler neck can be recognised
by the symbo
l  on the cap ››› Fig. 168 and
the dipstick by its coloured handle.
Check the engine oil level
● Pull out the dipstick and wipe it on a clean
cloth.
● Rep

lace the dipstick, pushing it in as far as
it wi
ll go. If the dipstick to measure engine oil
has a mark, when you reintroduce it this
mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the oil dipstick again and check
the engine oil
level.
● After reading the oil level, replace the dip-
stick
in the tube completely. WARNING
Oil could catch fire if it comes into contact
with hot en

gine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil
filler cap is correctly tightened. This will avoid engine oil spilling onto hot en-
gine par
t

s when the engine is running. CAUTION
● If the en gine oi

l level is above the area
››› Fig. 167 A do not start the engine. Seek
spec i
alist assistance. Otherwise catalytic
converter and engine damage may occur.
● When refilling or changing service liquids,
ensur
e that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! For the sake of the environment
The oil level must never be above area A .
Otherw i

se oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. Engine oil consumption
The consumption of engine oil can be differ-
ent
fr
om one en

gine to another and can vary
during the useful life of the engine.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 1 ltr./2000 km. In the
case of new vehicles, the consumption can
exceed this figure over 5,000 kilometres. For
this reason the engine oil level must be checked at regular intervals, preferably when
fillin

g the tank and before a journey.
When the engine is working hard, for in-
stance during sustained high-speed motor-
way cruising in summer or when climbing
mountain passes, the oil level should pref-
erably be kept within area ››› Fig. 167 A .
Topping up engine oil Read the additional information carefully

 page 30.
The engine oil must be changed regularly ac-
cording to the specifications of the Mainte-
nance Programme.
Due to the problems linked with disposing of
used oil and the need for suitable tools and
special knowledge, always visit a specialised
workshop to have the engine oil and filter
changed. SEAT recommends taking your car
in for technical service.
Detailed information on the service intervals
is shown in the Maintenance Programme.
Engine oil additives make new oil darker after
the engine has been running for a short peri-
od. This is normal and does not mean more
frequent oil changes are required.

Checking and refilling levels
WARNING
Only change the engine oil yourself if you
hav e the s
pecialist knowledge required!
● Before opening the bonnet, read and ob-
serve the w
arnings ››› page 184.
● Wait for the engine to cool down. Hot oil
may
cause burn injuries.
● Wear eye protection to avoid injuries, such
as ac
id burns, caused by splashes of oil.
● When removing the oil drain plug with your
finger
s, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact
with engine oil.
● Engine oil is poisonous! Used oil must be
stor
ed in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This c

ould 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
Before changing the engine oil, find a suita-
bl e loc

ation or service for proper disposal. For the sake of the environment
Always dispose of engine oil with the utmost
re s

pect for the environment. Never dispose of used engine oil in places such as a garden,
wood
s, dr

ains, roads, paths, rivers and drain-
age systems. Engine coolant
Introduction WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original
c ont ainer

, tightly shut and in a safe place.
● Never store engine coolant in empty food
container
s or bottles as other people may ac-
cidentally drink it.
● Always keep engine coolant out of reach of
chil
dren.
● Ensure that the proportion of engine cool-
ant ad
ditive corresponds to the lowest out-
side temperature to which the vehicle will be
exposed.
● If the outside temperature is extremely low,
the engine coo
lant could freeze causing the
vehicle to stop. As this would also cause the
heating to stop working, vehicle occupants
without warm clothing could freeze. For the sake of the environment
Coolants and additives can contaminate the
env ir

onment. If any fluids are spilled, they should be collected and correctly disposed
of, w
ith r

espect to the environment. Coolant warning lamp

Checking and refilling levels
●
Never open the c oo
lant expansion tank if
steam or coolant is coming from the engine
compartment. Wait until you cannot see or
hear any steam or coolant escaping.
● Always wait until the engine has complete-
ly coo
led before very carefully opening the
expansion tank cap. Contact with hot ele-
ments of the engine can cause skin burns.
● When the engine is warm or hot, the cool-
ing sys
tem is pressurised. Do not unscrew
the cap on the expansion tank when the en-
gine is hot. Otherwise, coolant may spray out
under pressure causing burns and serious in-
jury.
– Carefully and slowly unscrew the cap an-
ti-clockwise, gently pressing down on it.
– Always protect your face, hands and arms
from hot coolant and steam using a large,
thick cloth.
● When refilling liquids, avoid spilling them
on part
s of the engine and the exhaust sys-
tem. Spilled liquids could cause a fire. Under
specific circumstances, the ethylene glycol
can catch fire. WARNING
If there is not enough anti-freeze in the cool-
ant sy s

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 outs ide t

emperature 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. CAUTION
● If ther e i

s no appropriate coolant liquid
available, fill it using distilled water, and
nothing else. Any other type of water may
lead to considerable rusting in the engine
due to its chemical components. This could
consequently damage the engine. If you have
not used distilled water but another type of
water to top up the coolant, a specialised
workshop must immediately replace all of the
fluid in the engine cooling system.
● Only top up coolant to the top level of the
marked ar
ea ››› Fig. 169. Otherwise the ex-
cess coolant will be forced out of the cooling
system when the engine is hot, causing dam-
age.
● If a lot of liquid coolant has been lost, wait
for the engine t
o cool down completely before
adding coolant. Extensive coolant loss is an
indication of leaks in the engine cooling sys-
tem. Have the engine cooling system inspec-
ted immediately by a specialised workshop.
Otherwise engine damage may occur.
● When refilling service liquids, ensure that
you put
the liquids into the right tank. Mak-
ing a mistake when refilling could cause seri-
ous malfunctions and damage the engine! CAUTION
The original additives should never be mixed
with c oo

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
engine damage. Brake fluid

In the course of time, the brake fluid absorbs
water from the ambient air. If there is too
much water in the brake fluid, the brake sys-
tem could be damaged. In addition, the boil-
ing point of the brake fluid is significantly
lowered. When the brake fluid contains too
much water and the brakes are subject to
considerable forces, bubbles of water vapour
can form in the system. These bubbles can
significantly reduce braking power, notably
increasing braking distance, and could even
result in the total failure of the brake system. »

e fluid s

pecifications
SEAT have developed a special brake fluid
optimised for the brake systems of their vehi-
cles. To ensure the optimum working of the
brake system, SEAT recommends the use of
brake fluid in accordance with the VW 501 14
standard. If this brake fluid is not available or
another brake fluid is used for different rea-
sons, use a brake fluid that complies with the
United States standard FMVSS 116 DOT 4 or
the German standard DIN ISO 4925 CLASS 4
››› .
Br ak
e fluid

s conforming to the standard
VW 501 14, fulfil the American requirements
of the FMVSS 116 DOT 4 standard and the
German DIN ISO 4925 CLASS 4 standard.
However, fluids that comply with the Ameri-
can FMVSS 116 DOT 4 standard or the Ger-
man DIN ISO 4925 CLASS 4 standard do not
necessarily comply with the VW 501 14
standard. Always check the information on
the brake fluid container and ensure that you
are using suitable brake fluid.
A suitable brake fluid can be obtained from
SEAT dealerships. Brake fluid level
The level

of the brake fluid should always be
between the MIN and MAX marks, or above
the MIN mark ››› .
It i
s

not always possible to check the level of
the brake fluid, as in some models the en-
gine components make it difficult to see the
brake fluid reservoir. If you cannot read the
exact brake fluid level, consult a specialist.
The brake fluid level drops slightly when the
vehicle is being used due to wear of the
brake pads and the automatic readjustment
of the brake.
Changing the brake fluid
The brake fluid should be changed in accord-
ance with the instructions given in the Main-
tenance Programme. Have the brake fluid
changed by a specialised workshop. SEAT
recommends taking your car in for technical
service. This means that only brake fluid
complying with the required specifications
will be used. WARNING
If the brake fluid level is low or unsuita-
bl e/o

ld brake fluid is used, the brake system
may fail or braking power may be reduced.
● Check the brake system and the brake fluid
level
regularly! ●
The brak e fluid shou

ld be changed regular-
ly in accordance with the instructions given
in the Maintenance Programme.
● Always ensure that you use suitable brake
fluid. Only u
sed brake fluid that conforms to
the VW 501 14 standard, FMVSS 116 DOT 4
standard or even the DIN ISO 4925 CLASS 4
standard. Other types of brake fluid could af-
fect brake operation and reduce braking pow-
er. Do not use a brake fluid if the container
does not specify compliance with the
VW 501 14, FMVSS 116 DOT 4 or
DIN ISO 4925 CLASS 4 standards.
● The replacement brake fluid must be new.
● Brake fluid should be stored in the closed
original
container in a safe place out of reach
of children. Risk of poisoning!
● If the brake fluid is left in the system for
too long and the br
akes are subjected to
heavy use, vapour bubbles may form in the
brake system. This would seriously affect the
efficiency of the brakes and the safety of the
vehicle. This may cause an accident. CAUTION
Brake fluid damages the vehicle paintwork.
Wipe off an

y brake fluid from the paintwork
immediately. For the sake of the environment
Brake fluid is an environmental pollutant.

nition on. They will be turned off after a short
trip at a speed of between 15-20 km/h
(10-12 mph). If the warning indicators remain
lit, please visit a specialised workshop to
have the vehicle checked.
If the battery has been disconnected for a
long time, it is possible that the next service
date is not displayed or calculated correctly
››› page 86. Respect the maximum service in-
tervals permitted ››› Booklet Maintenance
Programme.
Automatic device disconnection
The intelligent vehicle electrical system auto-
matically implements a range of measures to
prevent the battery from discharging when
high demands are made on it:
● The idling speed is increased so that the al-
ternat
or provides more electricity.
● Where necessary, the power to the most
power
ful devices is reduced or even com-
pletely disconnected.
● On starting the engine, the power supply
from the 12-v
olt power sockets and the ciga-
rette lighter may be interrupted for a short
time.
The on-board management program cannot
always prevent the battery from running flat.
For example, if the ignition is left on for a long period with the engine off or if the side
lights or park

ing lights are left on while the
vehicle is stationary.
Why the battery runs flat:
● When stationary for a long time without
star
ting the engine, particularly if the ignition
is switched on.
● Use of electrical devices with the engine
switc
hed off. WARNING
Incorrectly securing the battery or using the
wron g b

attery can cause short-circuits, fire
and serious injuries.
● Always use only maintenance-free batter-
ies, prot
ected to prevent a leak, and whose
properties, specifications and size corre-
spond to the standard battery. WARNING
A highly explosive mixture of gases is re-
le a

sed when the battery is under charge.
● The batteries should be charged in a well-
ventil
ated room only.
● Never charge a frozen or recently thawed
batter
y. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
● Always replace a battery which has frozen.
● Battery cables not correctly connected may
cause a shor
t circuit. Reconnect first the posi-
tive cable and then the negative cable. CAUTION
● Never di s

connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Never plug accessories that supply current,
such a
s solar panels or a battery charger, to
the 12-volt power socket or the cigarette
lighter. This could damage the vehicle's elec-
trical system. For the sake of the environment
Dispose of the battery in an environment-
friendly m anner

. Batteries contain toxic sub-
stances such as sulphuric acid and lead. For the sake of the environment
Battery acid can contaminate the environ-
ment. C o

llect any spilt service fluids and dis-
pose of them correctly. 196
