Water in the fuel filter 1)
If
y
our vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Engine compartment

When work in
g underneath the vehicle, se-
cure it so that it cannot roll away and support
it safely on suitable supports. The hydraulic
jack is not sufficient for this purpose. Risk of
injuries!
● If any tests have to be performed with the
engine runnin
g, there is an extra safety risk
from rotating parts, such as the drive belt, al-
ternator and radiator fan, etc., and from the
high-voltage ignition system. You should also
note the following:
– Never touch the electrical wiring of the
ignition system.
– Keep away from moving engine parts
when wearing jewellery, loose clothing or
long hair. Risk of fatal injuries! All jewel- lery must be removed, hair tied back and
close-fitting clothing worn.

g up fluids, make sure the cor-
rect fluid is put into the correct filler opening. Otherwise this can cause serious malfunc-
tions
or en

gine damage!
● Never open the bonnet using the release
catc
h. Risk of damage! For the sake of the environment
Due to the environmentally-friendly disposal
of fluid s, the equipment

necessary and the

The layout of the engine compartment is very
simi l

ar to all petrol and diesel engines. Radiator fan
The radiator is driven by an electric motor
and c

lled according to the temperature
of the coolant.
After the engine has been stopped and the
ignition switched off, the radiator fan may
continue running for around 10 minutes. Engine oil
General
notes The engine comes with a special, multi-grade
oil
th

at can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.

The correct oil specifications for your engine
are listed in the ›››

Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,
this means that your vehicle has the LongLife
service programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terv
als.
● Only in exceptional circumstances, if the
engine oi l

level is too low ››› page 209 and
LongLife oil is not available, it is permitted to top up (once) with oil for
fixed ser
vice inter-
vals ›››
 page 41 (up to a maximum of 0.5
litres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals, which also appear in
›››  page 41. In this case, your vehicle
must be serviced after a fixed interval of 1
year/15,000 km (10,000 miles)(whatever
comes first) ››› Booklet Maintenance Pro-
gramme.
● In exceptional circumstances, if the engine
oil l
evel is too low ››› page 209 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore: ●
Avoid mi
xing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 209,
Checking engine oil level and you cannot ob-
tain the oil specified for your vehicle, you can
use a small quantity of oil (once) conforming
to the VW 506 00, VW 506 01, VW 505 00,
VW 505 01 or ACEA B3/ACEA B4 specification
(up to 0.5 l). Note
Before a long trip, we recommend finding an
engine oi l

that conforms to the correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed. Control lamp

Checking oil level – Park the vehicle on a level surface and en-
sure the en

gine is at operating tempera-
ture.
– Switch the ignition off.
– Open the bonnet.
– Wait a few minutes for the engine oil to
flow bac

k to the sump and remove the dip-
stick.
– Wipe the dipstick with a clean cloth and in-
sert it

again as far as it will go. –
Then pul
l the dipstick out again and check
the oil level.
It is normal for the engine to consume a cer-
tain amount of oil. Depending on how you
drive and the conditions in which the vehicle
is used, oil consumption can be up to 0.5 li-
tres per 1,000 km. Oil consumption can also
be higher for the first 5,000 km (3000 miles).
You should therefore check the oil level at
regular intervals, ideally every time you fill
the tank or before setting off on a long trip. CAUTION
● The oil l

evel must never exceed area A .
Risk of
damage to the exhaust system!
● If the engine oil cannot be topped up under
the given condition

Checking and refilling levels
– Re
a
d off the coolant level on coolant ex-
pansion tank ››› Fig. 207. When the engine
is cold, the coolant should be between marks B (min.) and
A (max.). When the
en gine i
s

hot, it may be slightly above mark
A (max.).
If the c
oo

lant fluid level in the reservoir is too
low, this will be indicated by the  red warn-
ing lamp illuminating on the general dash
panel ››› page 210, Control lamp . However,
we recommend checking the coolant level di-
rectly in the tank.
Coolant fluid loss
Any loss of coolant normally indicates a leak.
It is not sufficient merely to top up the cool-
ant. The cooling system should be inspected
by an Official Service without delay. CAUTION
● In the event of

a fault that causes the en-
gine to overheat, contact an authorised SEAT
dealer immediately, as this could damage the
engine.
● Anti-freeze that does not correspond to the
correct
specification may particularly affect
corrosion protection considerably.
● Faults caused by corrosion may lead to
cool
ant leaks. Risk of serious engine faults! Topping up the coolant level
–
Switch the ignition off.
– Wait for the engine to cool down.
– Cover the cap on the coolant expansion
tank ›

›› Fig. 207 with a cloth and carefully
unscrew the cap.
– Refill the level of coolant.
– Screw the cap on again until it clicks into
plac

e.
Do not use a different type of additive if the
prescribed anti-freeze additive is not availa-
ble, in the event of an emergency. In this
case, use only water and bring the coolant
concentration back up to the correct level as
soon as possible at an Official Service.
Always top up with unused coolant.
Never fill the coolant tank above mark A (max.)

Fig. 207 Excess coolant is forced
out of the cooling system through the over-
pressure valve in the filler cap of the expan-
sion tank when the engine heats up. WARNING
● The anti-freez e a

dditive and, therefore, the
entire coolant, are a health hazard. Avoid
touching the coolant. Coolant fumes are also
a health hazard. For this reason, always store
the coolant additive in a safe place out of the
reach of children. Risk of poisoning! ●
If s p

lashed into eyes, rinse immediately
with clean water and seek immediate medical
attention.
● Seek immediate medical attention if the
cool
ant is accidentally ingested. CAUTION
If the coolant cannot be topped up under the
giv en c ondition
