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. The slightly raised
pressures of warm tyres must not be reduced ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking tyre pressure
value 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 central console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument cluster display. The system uses
ESP ⇒page 183.
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!

 is displayed and indicates that the tyre pressure for a least
one tyre is insufficient.
– Stop the vehicle.
– Switch the engine off.
– Check the tyre(s).
– Change the wheel if necessary.
Tyre ser vice life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.

Technical Data
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒
page 234, fig. 153 , running across the tread. Depending on the make,
there will be six to eight 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 232.
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 234, fig. 154. 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.Anti-puncture tyres
Anti-puncture tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.Vehicles equipped with anti-puncture
23) tyres from the factory indi-
cate the loss of tyre pressure on the instrument panel.

Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 182.
– 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 anti-puncture 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 specialist 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 the loss in tyre pressure is displayed on the instrument panel, this
implies 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 anti-puncture
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 is being driven in emergency conditions, the driving
quality of the vehicle is impaired and there is a risk of accident.Note
•The anti-puncture tyres do not “deflate” on losing pressure because they
are supported on the reinforced sides. Therefore defects in the tyre can not be
detected with a visual inspection.•Snow chains must not be used on front tyres used in emergency
conditions.

Compact temporary spare wheel* (emergency 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 compact temporary spare wheel
Should you ever have a punctured tyre, the compact 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 compact 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 should 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.Note
•Vehicles with Brembo brakes must never use emergency wheels. These
vehicles are supplied with a tyre repair kit.

If and when
266Towing and tow-startingTo w - s t a r t i n g
The use of jump leads is preferable to tow-starting.We recommend that you do not tow-start your vehicle. Jump-starting
is preferable ⇒ page 263.
However, if your vehicle has to be tow-started:
– Engage the 2
nd or the 3
rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the gear lever into neutral. This helps to prevent driving into the towing
vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
Caution
When tow-starting, fuel could enter the catalytic converter and damage it.
CommentsPlease observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
– Drive slowly at first until the tow-rope is taut. Then accelerate gradually.
– Begin and change gears cautiously. If you are driving an auto- matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not working in the vehicle you are towing. Brake earlier than you
would normally, but with a more gentle pressure on the brake.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexperi-
enced drivers should not attempt to tow-start or tow away another vehicle.
