Tyre useful life Fig. 152
Tyre tread wear indicators. Fig. 153
Diagram for changing wheels The useful life of tyres is dependent on tyre
pressure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 152 , running across the tread. De- pendin
g on the m ake, there will be 6 to 8 of
them evenly spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
Tyre pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 175.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 153 . The use-
f u

l life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. 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.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If tyres show excessive wear, you should
have the wheel alignment checked by a Tech-
nical Service.
WARNING
There is a serious danger of accidents if a tyre
bursts during driving!
● The tyres must be replaced at the latest
when the tread wear indicators are worn
››› page 177. Failure to follow this instruction
could result in an accident. Worn tyres do not
grip well at high speeds on wet roads. There
is also a greater risk of “aquaplaning”.
● At continuously high speeds, a tyre with in-
sufficient pressure flexes more. This causes it
to overheat. This can cause tread separation
and tyre blow-out. Risk of accident. Always
observe the recommended tyre pressures.
● If tyres show excessive wear, you should
have the running gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid away from tyres.
● Damaged wheels and tyres must be re-
placed immediately! » 177

Under-inflated tyres will increase fuel con-
sumption. Run-flat tyres
Run-flat tyres allow you to continue driving
even with a punctured tyre, in the majority of
cases.
In vehicles that are factory-fitted with run-flat
tyres
1)
the loss of tyre pressure is indicated
on the instrument panel.
Driving with run-flat tyres (emergency
running)
– Leave the ESC/ASR on (Electronic Stability
Control), or switch it on ›››
page 137.
– Continue driving carefully and slowly
(80 km/h [50 mph] maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (e.g. kerbs) or
potholes.
– Pay attention if the ESC/ASR activates of-
ten, if smoke comes from the tyres or there
is a smell of rubber, the vehicle vibrates or
there are clattering noises. If any of these
occur, stop the vehicle. The run-flat tyres have a tag on the side of
the tyre, with the description: “DSST”, “Eufo-
nia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced.
When the tyres lose air they are supported on
the sides (emergency driving).
The loss of pressure in the tyre is shown on
the instrument panel. You can then drive a
maximum of 80 km (50 miles) and if the cir-
cumstances are favourable (e.g. low load),
even more.
The damaged tyre should be changed as
soon as possible. The rim should be checked
in a specialised workshop to detect possible
damage and replace it if necessary. We rec-
ommend you contact your technical service.
If more than one tyre is being used under
emergency conditions, this reduces the dis-
tance that can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on
the instrument panel, this means that at least
one tyre is being driven in emergency condi-
tions
››› .
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres, ●
there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue
driving even using run-flat tyres?
● If one of the tyres has been severely dam-
aged in an accident, etc. If a tyre has been
badly damaged there is a risk that parts of
the tread can be thrown off and cause dam-
age to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe
vibrations occur, or if the wheel starts over-
heating and gives off smoke. WARNING
When driving in emergency conditions, the
driving quality of the vehicle is considerably
impaired.
● The maximum permitted speed of 80 km/h
(50 mph) is subject to road and weather con-
ditions. Please observe related legal require-
ments.
● Avoid sharp turns and rapid manoeuvres,
and brake earlier than usual.
● Avoid driving over obstacles (e.g. kerbs) or
potholes.

the vehicle is impaired and there is a risk of
accident.
Note
● The run-flat tyres do not “deflate” on losing
pressure because they are supported on the
reinforced sides. Therefore defects in the tyre
cannot be detected with a visual inspection.
● Snow chains must not be used on front
tyres used in emergency conditions. New tyres and wheels
New tyres and wheels have to be run in.
The tyres and wheel rims are an essential
part of the vehicle's design. Those approved
by SEAT are specially matched to the charac-
teristics of the vehicle and make a major con-
tribution to good road-holding and safe han-
dling
››› .
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).
Tyres should be replaced at least in pairs and
not individually (i.e. both front tyres or both
rear tyres together). A knowledge of tyre des-
ignations makes it easier to choose the cor- rect tyres. Radial tyres have the tyre designa-
tions marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
Tyre width in mm
Height/width ratio in %
Tyre construction: Radial
Rim di

ameter in inches
Load rating code
Speed rating
The tyres could also have the following infor-
mation:
● A direction of rotation symbol
● “Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicated on
the tyre sidewall (possibly only on the inner
side of the wheel).
“DOT... 1103...” means, for example, that the
tyre was produced in the 11th week of 2003.
We recommend that work on tyres and
wheels be carried out by a Technical Service.
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. 195

T Any technical service has full information on
the technical requirements when installing or
changing tyres, wheels or wheel trims.
On vehicles with
all-wheel drive, all four tyres
must always be fitted with tyres of the same
type, make and tread pattern, as otherwise
the driveline can be damaged by continuous
differences in the wheel speeds. For this rea-
son, the spare wheel should have the same
wheel dimensions as the normal wheels so
that it will fit if there is a puncture. You may
also use the factory-supplied compact tem-
porary spare wheel. WARNING
● We recommend that you use only wheels
and tyres which have been approved by SEAT
for your model. Failure to do so could impair
vehicle handling. Risk of accident.
● 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.
● Never use old tyres or those with an un-
known “history of use”.
● If wheel trims are retrofitted, you must en-
sure that the flow of air to the brakes is not
restricted. This could cause the brake system
to overheat.
● All four wheels must be fitted with radial
tyres of the same type, size (rolling circumfer-
ence) and the same tread pattern. » 179

Advice
For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. This can also apply to wheels of the
same model. The use of wheels or tyres
which have not been approved by SEAT for
use with your model may invalidate the vehi-
cle's type approval for use on public roads.
● If the spare tyre is not the same as the
tyres that are mounted on the vehicle (e.g.
winter tyres) you should only use the spare
tyre for a short period of time and drive with
extra care. Refit the normal road wheel as
soon as possible. Wheel bolts
The design of wheel bolts is matched to the
rims. If different wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model
›››
page 147. After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench
››› . The tightening torque for steel
and alloy wheels is 120 Nm. WARNING
If the wheel bolts are not tightened correctly,
the wheel could become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
easily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the tightening torque of the wheel bolts
is too low, they could loosen whilst 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. CAUTION
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm. Winter service
Winter tyres In winter conditions winter tyres will consid-
erably improve the vehicle's handling. Sum-mer tyres (width, rubber compound, tread
pattern) provide less grip on ice and snow.
Winter tyres must be inflated to a
pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see sticker
on fuel tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ››› page 179, New
tyres and wheels determines the following
speed limits for winter tyres:
›
› › max. 160 km/h
max. 180 km/h
max. 190 km/h
max. 210 km/h
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres Q

Advice
●
Never start the engine when the vehicle is
on the jack. Risk of accident.
● If work is to be carried out underneath the
vehicle, this must be secured by suitable
stands. Otherwise, there is a risk of injury. Note
The jack does not generally require any main-
tenance. If required, it should be greased us-
ing universal-type grease. Compact spare wheel* (temporary
spare wheel)
Fig. 154
Luggage compartment. Accessing
the spare wheel. The compact spare wheel (temporary spare
wheel for vehicles without the anti-puncture
kit) should only be used when strictly neces-
sary. The temporary spare wheel is stored under
the floor panel in the luggage compartment
and is attached by a thumbnut.
How to use the temporary spare wheel
Should you ever have a punctured tyre, the
compact temporary spare wheel is only inten-
ded for temporary use until you can reach a
workshop. The standard-size road wheel
should be replaced as soon as possible.
Please note the following restrictions when
using the temporary spare wheel. This tem-
porary spare wheel has been specially de-
signed for your vehicle, thus, it cannot be re-
placed by a temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or win-
ter tyre) may be fitted on the compact tempo-
rary spare wheel rim.
Snow chains
For technical reasons, snow chains must
not
be used on the compact temporary spare
wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the com-
p act
temporary spare wheel in place of one of
the rear wheels. You can then attach the
snow chains to the wheel taken from the rear
and use this wheel to replace the punctured
front wheel. WARNING
● The tyre pressures must be checked and
corrected as soon as possible after fitting the
temporary spare wheel. The pressure of the
spare wheel sized 125/70R16 125/70R18
135/90R16 should be 4.2 bar
(61 psi/420 kPa). For other sizes, check the
label on the fuel cap. Failure to follow this in-
struction could result in an accident.
● Do not drive faster than 80 km/h (50 mph),
since higher speeds can cause an 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. Wheel change
Preparation work –
If you have a flat tyre or puncture, park the
vehicle as far away from the flow of traffic
as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the ve-
hicle. They should wait in a safe area (for
instance behind the roadside crash barri-
er).

Emergencies
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 only during 10 minutes at a maximum
speed of 80 km/h (50 mph) and subsequently
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
