Checking and refilling levels
Check the condition of all seat belts at regu-
l ar int
er
vals.
Very soiled belts may not retract properly. WARNING
● The seat belt

s should never be removed
from the vehicle for cleaning.
● Never clean using chemical products, as
chemica
l detergents destroy the fabric. En-
sure that the seat belts do not come into con-
tact with corrosive fluids such as acids, etc.
● If you find any damage to the belt webbing,
belt fitting
s, the belt retractor or the buckle,
the belt in question must be replaced by an
Official Service.
● Make sure that the inertia reel seat belts
are comp
letely dry before allowing them to
retract. Checking and refilling levels

Super unleaded 98 octane or super 95 oc-
t ane u
n
leaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling ››› .
Not al
l

petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› . SEAT recommends “genuine Volkswagen
Gr
oup F
uel

Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not r ef

uel if the filler indicates that the
fuel contains metal. LRP ( lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t

ank flap.
We recommend the use of diesel fuel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel). »

●
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.
● Observe the following additional warnings
if work
on the fuel system or the electrical
system is necessary.
–Always disconnect the battery from the
on-board network.
– Do not smoke.
– Never work near naked flames.
– Always keep an approved fire extinguish-
er immediately available. CAUTION
● When top pin

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
knowledge required, let an authorised SEAT
dealer change fluids during service inspec-
tions of the vehicle. Note
● Ple a

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 ›››
 page 40.
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 207 and
LongLife oil is not available, it is permitted to top up (once) with oil for
fixed ser
vice inter-
vals ›››
 page 40 (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 40. 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 207 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 207 and
you cannot obtain 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 ›››

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 208, 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. 208 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.)

● 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

Advice
●
A short c
ircuit is produced if the battery ter-
minals are bridged, e.g. using metal objects,
cables, etc. Possible consequences of a short
circuit: melting of lead plates, battery explo-
sion and fire, splashing acid.
● The following is forbidden while working on
the batter
y: fire and open flames, smoking
and activities that could produce sparks.
Avoid causing sparks when handling cables
or electrical apparatus. Risk of injury in the
event of large sparks.
● Before working on the electrical system,
you mus
t switch off the engine, the ignition
and all electrical components and disconnect
the cable from the negative terminal (-) of the
battery. To change a bulb, simply switch off
the corresponding light.
● Never charge a frozen or thawed out bat-
tery
. Risk of explosion and acid burns! Re-
place a frozen battery.
● Never use the jump leads on batteries in
which the electr
olyte level is too low. Risk of
explosion and acid burns!
● Never use a damaged battery. Risk of ex-
plos
ion! Replace a damaged battery immedi-
ately. CAUTION
● Never di s

connect the battery when the igni-
tion is switched on, as the electrical system
(electronic components) of the vehicle could
be damaged. When disconnecting the battery
from the vehicle electrical system, disconnect its negative terminal (-) first. Only then may
the pos
itiv

e terminal (+) be disconnected.
● When connecting the battery, first connect
the positiv
e terminal (+) and then the nega-
tive terminal (-). The battery cables must nev-
er be connected to the wrong battery termi-
nals. Risk of burning the electrical installa-
tion!
● Make sure the battery acid does not come
into cont
act with the bodywork. Risk of paint-
work damage.
● Do not expose the battery to direct sunlight
to prot
ect it from ultraviolet radiation.
● If the vehicle is not used for 3 or 4 weeks,
the batter
y could run flat. This is because
some components use electricity even in
standby mode (e.g. control units). Prevent the
battery from running flat by disconnecting its
negative terminal or leave it charging at a low
current.
● If you frequently use the vehicle for short
trips, the batt
ery may not fully charge and
could run flat. For the sake of the environment
A flat battery is particularly harmful waste for
the env ir

onment. It must therefore be dis-
posed of according to current local law. Note
Replace a battery once it is older than 5
