Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25°C
(-13°F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant.
To protect the cooling system, the percentage
of additive must always be at least 40 %, even in warm climates where anti-freeze pro-
tection is

not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Topping up cool-

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping

Checking and refilling levels
 Water in the fuel filter.
If thi s
is the case, take the vehicle to a speci-
alised workshop so that they can drain the
fuel filter.
Biodiesel* CAUTION
● Your v

ehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel fuel
by the diesel manufacturer in accordance
with standard EN 590 or DIN 51628 is author-
ised and will not cause damage to the engine
or the fuel system.
● The diesel engine has been designed to be
used ex
clusively with diesel fuel conforming
to standard EN 590. Never refuel or use pet-
rol, kerosene, fuel oil or any other type of
fuel. If you accidentally fill up the vehicle
with the wrong type of fuel, do not start the
engine. Seek assistance from specialised per-
sonnel. The composition of these fuels may
severely damage the fuel system and the en-
gine. Winter operation
Winter-grade diesel
When us
in

g “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0°C (+32°F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-grade diesel fuel” is available in some
countries during the cold months. It can be
used at temperatures as low as -22°C (-8°F).
In countries with different climatic conditions
the diesel fuel generally sold has different
temperature characteristics. Check with the
Technical Services or filling stations in the
country concerned regarding the type of die-
sel fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration in winter. This ensures that the fuel
system remains operational to approx. -24°C
(-11°F), provided you use winter-grade diesel
which is safe to -15°C (+5°F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24°C (-11°F), simply place the
vehicle in a warm place for a while. CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or s imi

lar additives with diesel fuel. Working in the engine compart-

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 ›››

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 »

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 201, safety notes
for work in the engine compartment .
● 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
● Bec au

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 oi l

down 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

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.
– Cover the coolant expansion tank cap with
a cloth and car

efully unscrew it to the left
››› .–
Top up the c
oo

lant only if there is still cool-
ant in the expansion 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
comply could result in poisoning. » 207

Advice
●
If w ork
ing inside the engine compartment,
remember that, even 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. 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
coo
lin

g 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. For the sake of the environment
Coolants and additives can contaminate the
en vir

onment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Brake fluid

reservoir has a black and yellow cap.
The brake fluid level drops slightly when the
vehicle is being used as the brake pads are
automatically adjusted as they wear. However, if the level goes down noticeably in
a short time, or dr

ops 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 100. WARNING
Before opening the bonnet to check the brake
fluid lev el, r

ead and observe the warnings

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

in the en

gine compartment on
page 201 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
could impair the braking effect.
