Advice
WARNING
The tyres must be replaced at the latest when
the tread is worn down to the tread wear indi-
cators. Failure to follow this instruction could
result in an accident.
● Especially in difficult driving conditions
such as wet or icy roads. It is important that
the tyre tread be as deep as possible and be
approximately the same on the tyres of both
the front and the rear axles.
● The scant driving safety due to insufficient
tread depth is particularly evident in vehicle
handling, when there is a risk of “aquaplan-
ing” in deep puddles of water and when driv-
ing through corners, and braking is also ad-
versely affected.
● The speed has to be adapted accordingly,
otherwise there is a risk of losing control over
the vehicle. Changing wheels
Fig. 178
Interchanging tyres. To ensure that the wear is equal on all tyres
the wheels should be changed round from
time to time according to the system
››› Fig. 178 . The useful life of all the tyres will
then be about the s
ame time.
Replacing wheels and tyres –
All four wheels must be fitted with tyres of
the same type, size (rolling circumference)
and preferably the same tread pattern.
– Tyres should be replaced at least in pairs
and not individually (i.e. both front tyres or
both rear tyres together). –
Do not use tyres whose effective size ex-
ceeds the dimensions of the factory-ap-
proved makes of tyre.
– If you 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 ty r

es 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 sizes 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 c on

sulted 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: 1)
COC = certificate of conformity.

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 pipes may be damaged, and
vehicle safety could be severely impaired
››› .
If you 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 is 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 manufac-
turer. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a serious safety risk. Risk of accident! It may
also invalidate the vehicle's registration for
use on public roads.
●
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.
● If wheel trims are fitted after the car is pur-
chased, ensure that there is an adequate flow
of air for cooling the brake system. For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● Never mount used tyres if you are not sure
of their “previous history”.
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. In some cases, this may also be true for
the same model of wheel. Wheel bolts

wheels fitted. After a long journey with varied
speeds the programmed values are collected
and monitored.
With the wheels under very heavy loads, the
tyre pressure must be increased to the total
recommended tyre pressure before the cali-
bration ››› page 243
. Note
● The tyre monitoring indicator does not
function when there is a fault in the ESC or

General information Fig. 181
Compact temporary spare wheel:
raised floor panel. The temporary spare wheel has been de-
signed to be used for short periods of time.
Have the tyres checked, and if necessary, re-
placed as soon as possible at a SEAT Official
Service or at a specialised workshop.
Please note the following restrictions when
using the compact temporary spare wheel.
The compact temporary spare wheel is de-
signed specifically for this model. For this
reason, do not use a temporary spare wheel
from a different type of vehicle.

Wheels
Removing the temporary spare wheel
– Lift and hold up the floor panel to remove
the temporary spare wheel ››› Fig. 181 .
– Turn the thumb wheel anti-clockwise.
– Take out the temporary spare wheel.
Chains
For 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
● After fitting the temporary spare wheel,
check the tyre pressures as soon as possible.
Failure to do so may cause an accident. The
tyre pressures are listed on the inside of the
fuel tank flap.
● Do not drive at over 80 km/h (50 mph)
when the temporary spare wheel is fitted on
the vehicle: risk of accident!
● Avoid heavy acceleration, hard braking and
fast cornering: risk of accident!
● Never use more than one temporary spare
wheel at the same time, risk of accident. ●
No other type of tyre (normal summer or
winter tyre) may be fitted on the compact
temporary spare wheel rim.
● If you are driving using the spare wheel,
the ACC system could automatically switch
off during the journey. Switch off the system
when starting off. Extraction of the spare wheel in

Winter service Winter tyres –
Winter tyres must be fitted on all four
wheels.
– Only use winter tyres that are approved for
your vehicle.
– Please note that the maximum permissible
speed for winter tyres may be lower than
for summer tyres.
– Also note that winter tyres are no longer ef-
fective when the tread is worn down.
– Af

ter 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 208.
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 sidew

all). »

Advice
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 210 .
W int
er 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

are available from the SEAT Official Service
and specialised workshop. Please note the
regulations to this effect in your country.
“All-weather” tyres can also be used instead
of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable
240 km/h (150 mph) speed rating for winter
tyres with the letter V is subject to technical
restrictions; the maximum permissible
speed for your vehicle may be significantly
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 winter tyres 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 possible 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. Snow chains
–
Snow chains can be used on the front
wheels only.
– Check that they are correctly seated after
driving for a few yards; correct the position
if necessary. Always take the manufacturer
assembly instructions into account.
– Keep your speed below 50 km/h.
– If there is a danger of being trapped de-
spite having mounted the chains, it is best
to disable the driving wheels (ASR) in the
ESC ›››

Fuses Introduction Due to the constant updating of vehicles,
fuse assignments based on equipment and
the use of the same fuse for various electrical
components, it is not possible to provide an
up-to-date summary of the fuse positions for
the electrical components at the time this
manual was printed. For detailed information
about the fuse positions, please consult a
technical service.
In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several
fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a special-
ised workshop as soon as possible.
WARNING
The high voltages in the electrical system can
give serious electrical shocks, causing burns
and even death!
● Never touch the electrical wiring of the igni-
tion system. » 231
