Wheels and tyres General notes –
When driving with new tyres, be especially
car
eful during the first 500 km (300 miles).
– If you have to drive over a kerb or similar
obstacle, drive very slowly and as near as
possible at a right angle to the obstacle.
– Check from time to time if the tyres are
damaged (punctures, cuts, cracks or
dents). Remove any foreign objects embed-
ded in the treads.
– Damaged wheels and tyres must be re-
placed immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as
possible.
– 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 stored in a cool, dry and preferably dark
place.
New tyres
New tyres do not give maximum grip straight
a w

ay and should therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km (300 miles). This will
also increase the useful life of the tyres.
The tread depth of new tyres may
v
ary, 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. Useful life of tyres Correct inflation pressures and sensible driv-
ing habits will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to any long trip.
– The tyre pressure should only be checked
when the tyres are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the vehicle.
– In vehicles with a tyre pressure indicator,
save the pressure of modified tyres
››› page 212 , ››
›
page 208.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The useful 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.
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.
208

Wheels
Depending on the vehicle, tyre pressure can
be adjusted (“comfort” tyre pressure) to in-
crease driving comfort. When driving with
comfort tyre pressure fuel consumption 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 pressures: 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.
WARNING
● Always adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicators
Fig. 177
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
worn.
The original tyres on your vehicle have
1.6 mm high “tread wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.)

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.

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

control of the vehicle and a serious or fatal
accident.
●
If the warning lamp  lights up, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sures or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pressure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 243.
● The ty r
e monitoring system can only oper-
ate correctly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can damage them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyres to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to more flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyres can overheat and burst resulting in
a loss of vehicle control. ●
Tyre pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not have to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING
Observe the safety warnings ››› in Control
and warning lamps on page 71. Note
● If excessively low tyre pressure is detected
with the ignition on, an audible warning will
sound. In the event that there is a fault in the
system, an audible warning will sound.
● Driving on dirt tracks for a long period of
time or driving in a sporty style can tempora-
rily deactivate the TPMS. The control lamp
shows a fault, but disappears when road con-
ditions or the driving style change. Tyre monitoring indicator
Fig. 179
Instrument panel: warning of loss of
tyre pressure. The tyre monitor indicator compares wheel
revolutions and, with this information, the
tread of each wheel using the ABS sensors. If
the rolling circumference of one or more
wheels has changed, the tyre monitoring in-
dicator will indicate this on the instrument
panel through a warning lamp and a warning
to the driver

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

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

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 wheel condition and hub mounting surfa-
ces. These surfaces must be clean before fit-
ting the wheel. CAUTION
When removing/fitting the wheel, the rim
may hit and damage the brake disc. For this
reason, please take care and get a second
person to assist you. Tyres with compulsory direction of
rotation
A directional tread pattern can be identified
by arrows on the sidewall that point in the di-
rection of rotation. Always observe the direc-
tion of rotation indicated when mounting the
wheel. This is important so that these tyres
can give maximum grip and avoid excessive
noise, tread wear and aquaplaning.
If, exceptionally, it is necessary to mount the
spare wheel* in the opposite direction of ro-
tation, please drive carefully, as in this case
the tyre does not have optimum conditions of
use. This is particularly important when driv-
ing on wet roads.
To benefit from the advantages of tyres with
this type of tread pattern, the defective tyre
should be replaced as soon as possible so
that all tyres again rotate in the correct direc-
tion. After changing a wheel –
On alloy wheels: replace the wheel bolt
caps.
– On plate wheels: replace the wheel hubcap
››› page 217.
– Put the tools and jack back in the luggage
compartment.
– If the replaced wheel does not fit in the
spare wheel housing, store it safely in the
luggage compartment ››› page 114.
– Check the tyre pressure of the newly moun-
ted tyre as soon as possible.
– In vehicles fitted with a tyre pressure indi-
cator, adjust the pressure and store the
reading in the radio/ Easy Connect system*
››› page 212.
– The wheel bolts should be tightened to 120
Nm. Check the torque as soon as possible
with a torque wrench. Meanwhile, drive
carefully.
– Have the flat tyre replaced as quickly as
possible. Tyre repair

Emergencies
TMS (Tyre Mobility System)* Read the additional information carefully
›››  page 33
The Anti-puncture kit* (Tyre Mobility System)
will reliably seal punctures caused by the
penetration of a foreign body of up to about
4 mm in diameter. Do not remove foreign ob-
j
ects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tire mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tire mobility set! Otherwise, you
should seek professional assistance.
The tyre sealant must not be used in the
following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20°C (-4°F).
● In the event of cuts or perforations in the
tyre greater than 4 mm.
● If you have been driving with very low pres-
sure or a completely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
gerous, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury:
● Stop the vehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid.
● All passengers and particularly children
must keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other road users.
● Use the tyre mobility system only if you are
familiar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tire mo-
bility set as soon as possible.
● The sealant is a health hazard and must be
cleaned immediately if it comes into contact
with the skin.
● Always keep the tire mobility set out of the
reach of small children.
● Never use an equivalent jack, even if it has
been approved for your vehicle.
● Always stop the engine, apply the hand-
brake lever firmly and engage gear if using a manual gearbox, in order to reduce the risk of
vehicle involuntary movement.
WARNING
A tyre filled with sealant does not have the
same performance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fast cornering.
● Drive for only 10 minutes at a maximum
speed of 80 km/h (50 mph) and then check
the tyre. For the sake of the environment
Dispose of used or expired sealant observing
any legal requirements. Note
A new bottle of sealant can be purchased at
SEAT dealerships. Note
Take into account the separate instruction
manual of the tyre mobility set* manufactur-
er. 221
