hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Da nger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is applied.
Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered. −
Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.
Caution
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the grou nd underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected at a specialised
workshop.

Wheels and tyres
250Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the same direction of rotation when they are installed again.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel rims.New tyres
New tyres must be run in ⇒page 205.
The tread depth of new tyres may vary, according 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
vibrations or the vehicle pulling to one side, this may indicate that one of the
tyres is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•New tyres do not have maximum grip during the first 500 km. Drive
particularly carefully to avoid possible accidents.•Never drive with damaged tyres. This may cause an accident.•If you notice unusual vibrations or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce the
slightly raised pressures of warm tyres ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low, there
is an increased danger of accidents - particularly at high speeds.•A tyre can easily burst if the pressure is too low, causing an accident!•At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.•If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre pressure monitoring
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system uses the speed sensors of the ABS wheels. It operates by
analysing the speed and frequency spectrum of each wheel.
For optimum performance, use genuine SEAT tyres. In addition, check and
adjust tyre pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the centre console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system uses ESP
⇒ page 199.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases about 0.1 bar for each 10 °C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise
accordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!

Wear indicators
The original tyres on your vehicle have 1.6 mm high tread wear indicators
⇒
page 252, fig. 174 , running across the tread. Depending on the make,
there will be 6 to 8 of them evenly spaced around the tyre. Markings on the
tyre sidewall (for instance the letters “TWI” or other symbols) 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 indica-
tors). Worn tyres must be replaced. 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 250.
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 cha nge t he m ar oun d as sh own ⇒ page 252, fig. 175. All the tyres will then
last for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, 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 align-
ment checked by an Authorised Service Centre.
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 is worn down to
the tread wear indicators. Failure to do so 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 insufficient 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 pres-
sures.•If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.•Keep chemicals such as oil, fuel and brake fluid away from tyres.•Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.Run-flat tyres
Run-flat tyres allow you to cont inue driving even with a punc-
tured tyre, in the majority of cases.In vehicles that are factory-fitted with run-flat tyres

Driving with run-flat tyres (emergency running)
– Leave the ESP/TCS (Electronic Stability Programme) switched on, or switch on ⇒ page 199.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. 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”, “Eufonia”, “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 and if the circumstances are favourable (for
example, 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 recommend you contact Technical Service. If more than one
tyre is being used under emergency co nditions, this reduces the distance
which 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 conditions ⇒.
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 damaged 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 damage 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 overheating 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 is subject to road and
weather conditions. Please observe legal requirements when doing so.•Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.•Avoid driving over obstacles (for example kerbs) or potholes.•If one or more tyres are being driven in emergency conditions, the
driving quality of 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.

stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒
page 255, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyres must not be exceeded. Otherwise,
this could lead to tyre damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not wear
so quickly and reduce fuel consumption.Snow chainsSnow chains are only permitted on front wheels and only for tyres 195/65R15
and 205/55R16. These tyres may only be fitted with fine-pitch link chains
which do not protrude more than 15 mm ⇒page 255.
Other tyres may use fine-pitch links which do not protrude more than 9 mm,
including tension device.
Remove wheel hub covers and trim rings before fitting snow chains. For safety
reasons cover caps, available in any Authorised Service Centre, must then be
fitted over the wheel bolts.
All-wheel drive : Where snow chains are compulsory on certain roads, this
normally also applies to cars with all-wheel drive. Snow chains may only be
fitted to the front wheels (also on vehicles with all-wheel drive).
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer’s instructions. This will prevent the chains coming into contact
with the wheel housing.
Caution
Remove the snow chains to drive on roads without snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
Note
•In some countries, the speed limit for using snow chains is 50 km/h. The
legal requirements of the country should be followed.•We recommend that you ask your Authorised Service Centre for informa-
tion about appropriate wheel, tyre and snow chain size.

Compact temporary spare wheel*
The compact spare wheel (emergency wheel for vehicles
without the anti-puncture kit) should only be used when
strictly necessary.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 temporary spare wheel is only
intended 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 spare wheel has been specially designed for your vehicle, thus, it cannot
be changed with the spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim. Snow chains
For technical reasons, snow chains must
not be used on the compact tempo-
rary spare wheel.
If you have a puncture on one of the front wheels when using snow chains, fit
the compact temporary spare 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.
The emergency tyre pressure for dimensions 125/70R16 125/70R18
135/90R16 is 4.2 bar; for all other tyre dimensions please refer to the label
on the fuel cap. Failure to do so could result in an accident.•Do not drive faster than 80 km/h. Higher speeds can cause an accident.•Avoid heavy acceleration, hard braking and fast cornering. Risk of acci-
dent.•Never use two or more compact spare tyres 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.
Tyre repair kit
The tyre repair kit (for vehicles not including a spare wheel) is
stored under the floor panel in the luggage compartment.In the event of a punctured tyre, your vehicle is equipped with the Tyre
Mobility System.
The tyre repair kit consists of a container with sealing compound to repair the
puncture and a compressor to generate the required tyre pressure. The kit will
