Advice
In right-hand drive vehicles the brake fluid
r e
ser
voir is on the other side of the engine
compartment.
Changing brake fluid
The regular intervals at which the brake fluid
should be replaced are listed in the Mainte-
nance Programme. We recommend you have
it replaced at a SEAT Official Service, during
an Inspection Service. WARNING
● Brak e fluid shou

ld 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 should not come into contact with
the v ehic

le paintwork, as it is abrasive. Windscreen washer reservoir

lear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).
● All year round, G 052 164 A2 for clear
glas
s. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4 proportion of mixture in the washer fluid
tank.
Cap

acity
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not c ont

ain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contain
s enough anti-freeze.
● In cold conditions, you should not use the
winds
creen washer system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
simi l

ar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by
SEAT.
● If necessary, add a suitable antifreeze to
the water in the r
eservoir.252

Checking and refilling levels
CAUTION
● Do not mi x
cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely c
ertain that you fill the fluids into the
correct reservoirs. Using the wrong fluids
could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
vis
ibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery

Wheel s
and ty

res
General notes –
When driving with new tyr e
s, be especially
careful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obs

tacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
dam ag

ed (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
plac

ed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
poss

ible.
– Mark the wheels before taking them off so
that they

rotate in the same direction when
put back.
– When removed, the wheels or tyres should
be stor

ed in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
away and should therefore be “run in” by driving carefully and at moderate speeds for
about the firs

t 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.
Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibration or the
car pulling to one side, this may indicate that
one of the tyres is damaged. Reduce speed
immediately if there is any reason to suspect
that damage may have occurred. Inspect the
tyres for damage. If no external damage is
visible, drive slowly and carefully to the near-
est specialised workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on single drive tyres. Al-
ways note the direction of rotation indicated
when mounting the wheel. This guarantees
optimum grip and helps to avoid aquaplan-
ing, excessive noise and wear.
Retrofitting accessories
If you wish to change or fit wheels, rims or
wheel trims, we recommend that you consult
with a SEAT Official Service centre for advice
regarding current techniques.

in
g h
ab
its will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to an

y long trip.
– The tyre pressure should only be checked
when the tyre

s are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the

vehicle. –
In vehic
les with a tyre pressure indicator,
save the pressure of modified tyres
››› page 259, ››› page 256.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The usef

ul life of your tyres depends on the
following factors:
Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap
››› Fig. 237.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
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.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap. Do not forget the spare wheel when checking
the tyre pr

essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to
a pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If you notice excessive tyre wear, you should
check wheel alignment at a SEAT Official
Service.

Advice
– If
y
ou wish to fit the vehicle with rims or
tyres different to those installed in manu-
facture, it is advisable to consult a SEAT Of- ficial Service before purchasing them.
The tyres and wheel rims are an essential
part of the vehicle's design. The tyres and
rims approved by SEAT are specially matched
to the characteristics of the vehicle and make
a major contribution to good roadholding
and safe handling ››› .
The s iz
e

s of the rims and tyres approved for
your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or
COC document 1)
). The vehicle documentation
varies depending on the country of resi-
dence.
Note for Italy: A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2).
A knowledge of tyre designations makes it
easier to choose the correct tyres. The follow-
ing wording can be read on the sides of the
tyre:
205/55 R16 91V
This contains the following information:
205Tyre width in mm
55Height/width ratio in %
RTyre construction: Radial
16Rim diameter in inches
91Load rating code
VSpeed index The manufacturing date is also indicated on
the ty
r

e sidewall (possibly only on the inner
part):
DOT ... 2212 ...
it means, for example, that the tyre was man-
ufactured in the 22nd week of 2012.
But note that with some types of tyre, the ac-
tual tyre size can differ from the nominal size
marked on the tyre (for instance 205/55 R 16
91 W), and there may be significant differen-
ces in the contours of the tyres, even though
the tyres are marked with the same nominal
size designation. When replacing the tyres,
it is therefore important to make sure that
the actual size of the new tyres does not ex-
ceed the dimensions of the factory-approved
makes of tyre.
Failure to observe this requirement can af-
fect the clearance needed for the tyres. If the
tyres rub against the bodywork, in certain circumstances the tyres , suspension or
bodywork
and pipe

s may be damaged, and
vehicle safety could be severely impaired
››› .
If
y

ou use tyres that are approved by SEAT
you can be sure that the actual tyre dimen-
sions will be correct for your vehicle. If you
decide to fit a different type of tyre, you must
obtain the appropriate manufacturer's certif-
icate from the tyre retailer to confirm that
the tyres are suitable for your vehicle. Keep
this certificate in a safe place.
Your SEAT Official Service will be able to ad-
vise you on which tyres may be fitted to your
vehicle.
It is best to have all servicing of wheels and
tyres performed by a specialised workshop.
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 respecting the envi-
ronment. WARNING
● It i s

very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not re-
ly entirely on the nominal tyre size marked on
the tyre, since the effective tyre size can dif-
fer significantly depending on the 1)

F

or technical reasons, snow chains must not
be used on the temporary spare wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the tem-
porary spare wheel in place of one of the rear
wheels. Fit the snow chains on the rear wheel
that you have removed and replace the punc-
tured front wheel with this wheel. WARNING
● Aft er fittin

Winter service Winter ty
res–
Winter tyres must be fitted on al
l
four
wheels.
– Only use winter tyres that are approved for
your v

ehicle.
– Please note that the maximum permissible
speed for w

inter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the

tread is worn down.
– After fitting the wheels you must always
check

the tyre pressures. The correct tyre pressures are listed on the sticker on the
inside of

the fuel tank flap ››› page 256.
In winter road conditions winter tyres will
considerably improve vehicle handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives less grip on ice
and snow. This applies particularly to vehi-
cles equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's docu-
ments (e.g. EC Certificate of Conformity or
COC 1)
). The vehicle documentation varies de-
pending on the country of residence. See al-
so ››› page 257.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
Winter tyres are subject to the following max-
imum speed limits according to speed rating

lower. The maximum speed limit for these
ty r
es depends directly on the maximum axle
weights for your car and on the listed weight
rating of the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted for
the wint er ty

res fitted on your car can cause
tyre failure, resulting in a loss of control of
the vehicle – risk of accident. For the sake of the environment
Summer tyres should be fitted again as soon
as po

ssible after the winter period; they give
better handling on roads which are free of
snow and ice. Summer tyres perform with
less rolling noise, tyre wear and – most im-
portant – reduce fuel consumption. 264
