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-

We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 59.
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 program. If it lists the codes QI1, QI2,
QI3, QI4 or QI7, the interval service is de-
pendent on the 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 mi xing it with oil for fixed service in-
tervals.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 277 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 59 (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 59. 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 277 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, m

ay 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 mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil
level is too low ››› page 277,
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. Warning lamp
If this warning lamp
 is
r
ed it indicates
that the engine oil pressure is too low.
If this warning symbol starts to flash, and is
accompanied by three audible warnings,
switch off the engine and check the oil level.
If necessary, add more oil ›››

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 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.

Advice
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. For the sake of the environment
Coolants and additives can contaminate the

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 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

General notes Avoiding damage
– If you have to drive over a kerb or similar
ob s

tacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, c r

acks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to m

aintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be s

tored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position, if they are
not fitted on wheel

rims.

o tyres and rims is often not readily
visible. If you notice unusual vibrations or the
vehicle pulling to one side, this may indicate
that one of the tyres is damaged. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear. WARNING
● New tyr e

s do not have maximum grip dur-
ing the first 500 km. Drive particularly care-
fully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an ac
cident.
● If you notice unusual vibrations or if the ve-
hicle p
ulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Tyre pressure monitoring system

Location of the tyre pressure sticker. The maximum tyre pressure values are shown
on a s
tic
k

er stuck to the back of the left front
door frame ›››
Fig. 239.
1. Read the required tyre inflation pressure from the stic
ker. The values refer to Sum-
mer tyres.
2. The tyre pressures should only be checked when the tyre
s are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carr
ying. Tyre pressure
The correct

tyre pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and before starting a journey.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When
driving with comfort tyre pressure fuel con-
sumption may increase slightly. WARNING
A tyre can easily burst if the pressure is too
low , c

ausing an accident!
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. In this way it
becomes too hot, and this can cause tread
separation and tyre blow-out. Always observe
the recommended tyre pressures.
● If the tyre pressure is too low or too high,
the tyre
s will wear prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. 284

Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 240, running across the tread. De- pending on the make, there will be 6 to 8 of
them evenly

spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
T y
r

e pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 284.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 241. The use-
ful life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherw

ise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If tyres show excessive wear, you
should have the wheel alignment checked by
a Technical Service. WARNING
There is a serious danger of accidents if a tyre
bur s

ts during driving!
● The tyres must be replaced at the latest
when the trea
d wear indicators are worn
››› page 285. Failure to follow this instruction
could result in an accident. Worn tyres do not
grip well at high speeds on wet roads. There
is also a greater risk of “aquaplaning”.
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. This causes it
to overheat. This can cause tread separation
and tyre blow-out. Risk of accident. Always
observe the recommended tyre pressures.
● If tyres show excessive wear, you should
have the ru
nning gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid awa
y from tyres.
● Damaged wheels and tyres must be re-
plac
ed immediately! » 285

New tyres and wheels have to be run in.
The tyr
e
s and wheel rims are an essential
part of the vehicle's design. Those approved
by SEAT are specially matched to the charac-
teristics of the vehicle and make a major con-
tribution to good road-holding and safe han-
dling ››› .
T y
r

es should be replaced at least in pairs and
not individually (i.e. both front tyres or both
rear tyres together). A knowledge of tyre des-
ignations makes it easier to choose the cor-
rect tyres. Radial tyres have the tyre designa-
tions marked on the sidewall, for example:

● A direction of

rotation symbol
● “Reinforced” denotes heavy-duty tyres.
The manufact
uring date is also indicated on
the tyre sidewall (possibly only on the outer
side of the wheel).
“DOT... 1116...” means, for example, that the
tyre was produced in the 11th week of 2016.
We recommend that work on tyres and
wheels be carried out by a Technical Service.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres.
Any technical service has full information on
the technical requirements when installing or
changing tyres, wheels or wheel trims. WARNING
● We r ec

ommend that you use only wheels
and tyres which have been approved by SEAT
for your model. Failure to do so could impair
vehicle handling. Risk of accident.
● Avoid running the vehicle on tyres that are
more than 6
years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● Never use old tyres or those with an un-
known “his
tory of use”. ●
If wheel trims

are retrofitted, you must en-
sure that the flow of air to the brakes is not
restricted. This could cause the brake system
to overheat.
● All four wheels must be fitted with radial
tyre
s of the same type, size (rolling circumfer-
ence) and the same tread pattern. For the sake of the environment
Old tyres must be disposed of according to
the l aw

s in the country concerned. Note
● A S EA

T Service Centre should be consulted
to find out whether wheels or tyres of differ-
ent sizes to those originally fitted by SEAT
can be fitted, and to find out about the com-
binations allowed between the front axle
(axle 1) and the rear axle (axle 2).
● For technical reasons, it is not generally
poss
ible to use the wheels from other vehi-
cles. This can also apply to wheels of the
same model. The use of wheels or tyres
which have not been approved by SEAT for
use with your model may invalidate the vehi-
cle's type approval for use on public roads.
● If the spare tyre is not the same as the
tyre
s that are mounted on the vehicle (e.g.
winter tyres) you should only use the spare
tyre for a short period of time and drive with
extra care. Refit the normal road wheel as
soon as possible. 286
