Tyre monitoring systems Introduction WARNING
Unsuitable handling of the wheels and tyres
may lead to sudden tyre pressure losses, to
tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure
they are maintained at the pressures indica-
ted. Tyre pressure that is too low could cause
overheating, resulting in tread detachment or
even burst tyres.
● Tyre pressure should be that indicated on
the label when the tyres are cold at all times
››› page 243.
● Re
gularly check the cold inflation pressure
of the tyres. If necessary, change the tyre
pressure of the vehicle tyres while they are
cold.
● Regularly check your tyres for damage and
wear. ●
Never exceed the maximum permitted
speed or loads specified for the type of tyre
fitted on your vehicle. For the sake of the environment
Under-inflated tyres lead to increased fuel
consumption and tyre wear. Note
● Driving for the first time with new tyres at a
high speed can cause them to slightly ex-
pand, which could then produce an air pres-
sure warning.
● Only replace used tyres with those author-
ised by SEAT for the corresponding type vehi-
cle.
● Do not only rely on the tyre monitoring sys-
tem. Regularly check your tyres to ensure
that the tyre pressure is correct and that the
tyres are not damaged due to puncture, cuts,
tears and impacts/dents. Remove objects
from the tyres only when they have not
pierced the tyres. Tyre monitor indicator warning lamp

The pressure in one or more tyres has
clearly reduced in comparison to the
tyre pressure set by the driver or the
tyre has structural damage.
Additionally, an audible warning can be heard and a text
message can be seen on the instrument panel display.
Stop the vehicle!
Reduce speed immediately! Stop
the vehicle safely as soon as possible. Avoid sudden
manoeuvres and braking! Check all tyres and pressures.
Replace any damaged tyres. If flashing

System malfunction
The control lamp flashes for approximately one minute
and then lights up permanently.
If tyre pressure is correct, switch the ignition off and on
again. If the control lamp remains lit up, the tyre moni-
toring indicator can be calibrated. Have the system
checked by a specialised workshop.
Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on while the function is verified. They will
switch off after a few seconds.
WARNING
When the tyres are inflated at different pres-
sures or at a pressure that is too low then a
tyre may be damaged resulting in a loss of 212

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

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

Advice
8. Start the engine of the vehicle with the flat battery and wait 2 or 3 minutes until the
engine is “running”.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam headlights (if they
are switched on).
10.Turn on the heater blower and heated rear window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11. When the engine is running, disconnect
the l e
ads in reverse order to the details
given above.
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about 1 minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 198.
● The b att

ery providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint on battery). Failure to comply could result in
an explosion.
●
Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow-starting the
vehicle
General information Read the additional information carefully
›››  page 35
Points to observe when tow-starting or tow-
ing away
If you use a tow rope:
Notes for the driver of the towing vehicle
– The tow rope must be taut before you drive
off.
– Release the clutch very carefully when start-
ing the vehicle (manual gearbox), or accel-
erate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope
. Both drivers should
be f
amiliar with the technique required for
towing. Inexperienced drivers should not at-
tempt to tow.

Advice
Vehicles with towline anchorage
On the right of the rear bumper there is a cov-
er which covers a threaded hole. – Take the towline anchorage out of the vehi-
cle tool set ››› page 220 .
– To r
emove the bumper cover, just press the
upper side of the cover inwards (arrow) and
remo

ve the cover by levering on the lower
››› Fig. 192 side.
– Scr

ew the towline anchorage into the screw
connection as far as it will go ››› Fig. 193
and tighten with the wheel brace.
After use, unscrew the towline anchorage
and put it back in the vehicle tool kit. Replace
the cover on the bumper. The towline anchor-
age should always be kept in the vehicle. WARNING
● If the towline anchorage is not screwed in
as far as the stop, there is a risk of the screw
connection shearing off during towing (acci-
dent risk).
● If your car has a towing bracket, only use
special towing ropes. Risk of accident! CAUTION
In vehicles fitted with a towing bracket, only
use special tow bars to prevent damage to
the ball joint. These tow bars have been spe-
cially approved for use with towing brackets. Tow-starting
As a general rule, tow-starting is not recom-
mended.
– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch the ignition on.
– Once both vehicles are moving, release the
clutch.
– As soon as the engine has started, press
the clutch and move the gear lever to neu-
tral.
If the engine will not start, it is best to try
starting it using the battery of another vehi-
cle ›››
page 223 before attempting to tow
s t

art. You should only try to tow-start the en-
gine if jump starting is not successful. Tow-
starting is an attempt to start the engine via
the movement of the wheels.
When tow-starting a vehicle with a petrol en-
gine
, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter. WARNING
The risk of accidents is high when tow-start-
ing, for example, the towed vehicle can easily
be driven into the towing vehicle. CAUTION
Do not tow vehicles for more than 50 km. Risk
of damage to the catalytic converter. Towing vehicles with a manual
gearbox
Towing is relatively straightforward.
Please observe the relevant instructions
››› page 224.
The v

ehicle can be towed using a tow bar or
tow rope in the normal way, with all four
wheels on the road; it can also be towed with
either the front or rear wheels lifted off the
road. The maximum towing speed is 50 km/h
(30 mph).
To

wing a vehicle equipped with
automatic gearbox Certain restrictions must be observed when
towing your vehicle.
Please observe the relevant instructions
››› page 224 .
The v

ehicle can be towed with a tow bar or
tow rope in the normal way, with all four
wheels on the ground. When doing so,
please note the following points:

● Replace the wiper arm on the rear window. WARNING
Worn or dirty wiper blades reduce visibility
and increase the risk of accident and serious
injury.
● Always replace damaged or worn blades or
blades which do not clean the windscreen
correctly. CAUTION
● Damaged or dirty windscreen wipers could
scratch the glass.
● If products containing solvents, rough
sponges or sharp objects are used to clean
the blades, the graphite layer will be dam-
aged.
● Never use fuel, nail varnish remover, paint
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

formation consult the European Union Publi-
cations Office at EUR-Lex: © European Union,
http://eur-lex.europa.eu/en/index.htm) and
are valid for the kerb weight indicated for the
vehicle.

Technical specifications
Note
In practice, and considering all the factors
mentioned here, consumption values can dif-
fer from those calculated in the current Euro-
pean regulations. Weights
Kerb weight refers to the basic model with a
fuel tank filled to 90% capacity and without
optional extras. The figure quoted includes
75 kg to allow for the weight of the driver.
Special versions, optional equipment fittings
or retro-fitting accessories will increase the
weight of the vehicle

WARNING
● Please note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Always adjust your speed and driving
style to suit road conditions and require-
ments.
● Never exceed the gross axle weight rating
or the gross vehicle weight rating. If the per-
missible axle load or the permissible total
weight is exceeded, the driving characteris-
tics of the vehicle may change, which could
lead to accidents, injuries and damage to the
vehicle. Towing a trailer
Trailer weights Trailer weight
The trailer weights and drawbar loads ap-
proved are selected in intensive trials accord-
ing to precisely defined criteria. The ap-
proved trailer weights apply to vehicles in the
EU and generally for maximum speeds of 80
km/h (100 km/h in c
er
tain circumstances).
The figures may be different in other coun-
tries. All data in the official vehicle documen-
tation takes precedence over these data at all
times ››› .
Drawbar loads
The maximum
permitted drawbar load on the
b

all joint of the towing bracket must not ex-
ceed
80 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For safety reasons, do not exceed the 80
km/h (50 mph) limit. This is also valid in
countries where higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawbar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels
