Advice
● The vehicle is unbalanced because of a
load
● The wheels on an axle are subject to a
heavier load (e.g. with a heavy load).
● The vehicle is fitted with snow chains
● The temporary spare wheel is fitted
● The wheel on one axle is changed
There may be a delay in the reaction of the
tyre 
monitoring indicator or it may not in-
dic
ate anything under certain circumstances
(e.g. sporty driving, snow-covered or un-
paved roads, or when driving with snow
chains).
Calibrating the tyre monitoring
indicator Fig. 180
Glove compartment: tyre control
switch. After changing the tyre pressure or replacing
one or more wheels, the tyre monitoring indi-
cator must be recalibrated. Do the same, for
example, when the front and rear wheels are
swapped.
● Switch the ignition on.
● Store the new tyre pressure in the Easy
Connect system with the button  and the
function button Setup

 page 17 or us-
ing the switch located in the glove compart-
ment* ››› Fig. 180 .
When driv in
g, the system self-calibrates the
tyre pressure provided by the driver and the
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
ABS ››› page 143.
● An err oneou

s indication may be given when
snow chains are in use because they increase
the tread of the wheel. Compact temporary spare
wheel
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
vehicles with SEAT SOUND 10
speakers (with
subwoofer)* –
Disassemble the subwoofer's
floor panel
(c
arpet) as follows:
– LEON/LEON SC model: first, pull the carpet
in the direction of the backrest and then
pull it upwards to remove it. LEON ST mod-
el: lift and secure the floor storage com-
par
tment as explained in ››› page 121.
– Disconnect the subwoofer's speaker cable.
– Turn the sec

uring wheel anti-clockwise.
– Remove the subwoofer speaker and the
s

pare wheel.
– When replacing the spare wheel, place the
subwoofer speaker in the direction indica-
ted b

y the arrow and with the word
“FRONT” facing forward.
– Reconnect the speaker cable and firmly ro-
tate the securing wheel clockwise so that the subwoofer system and wheel are firmly
in place.
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). »

The essentials

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

Y300 km/h Vehicles capable of exceeding these speeds
must have an appropriate
sticker attached so
that it is visible to the driver. Suitable stickers
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 ›››

thinner or similar products to clean the win-
dows.
● In icy conditions, always check that the
wiper blades are not frozen to the glass be-
fore using the wipers. In cold weather, it may
help to leave the vehicle parked with the wip-
ers in service position ››› page 230. Fuses and bulbs
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

Wheel bolts
After the wheels have been changed, the
tightening torque
of the wheel bolts should
be c hec

ked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and alloy wheels is 120 Nm. WARNING
● Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Service for information about appropriate
wheel, tyre and snow chain size. 244
