Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.The tyre pressure monitoring system makes use of the ABS sensors to
compare the rolling circumference and the frequency characteristics of the wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp
~ will light up. The fault
will also be indicated by a warning buzzer. The position of the affected tyre
will also be shown (if only one tyre is affected) on the centre display of the
instrument panel.
The rolling circumference and frequency characteristics can change if:
•the tyre pressure is too low.•the tyre has suffered structural damage.•the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).•there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).•the road surface under the left wheels is different to the road surface
under the right wheels for a long period.•when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modify the
tyre pressure ⇒page 241 or after changing or swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 173. The yellow warning lamp
~ will light up. Hold the button down
for 2 seconds until the warning lamp goes out and an acoustic warning is
given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre pres-
sure must be increased to the recommended value for the maximum load
(see the adhesive label on the inside of the fuel tank flap) and then initialise
the system.
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp
~ will light
up for about 2 seconds. There is a fault in the system if the indicator stays on
permanently after switching on the ignition. The instrument panel also

qualified workshop as soon as possible.
The tyre pressure warning lamp
~ lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒.
WARNING
•If the tyre pressure warning lamp lights up
~ you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
•The driver is responsible for maintaining correct tyre pressures. There-
fore, the tyre pressure must be regularly checked.•Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp
~ may not light
up immediately or not at all.
•Please ask your Dealer or qualified workshop whether run-flat tyres can
be used on your vehicle. Fitting this type of tyre in an undue manner could
lead to your driving licence being taken away from you. Furthermore, it may
led to damage to the vehicle or, under certain circumstances, may cause
accidents.•If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Dealer or a qualified workshop.Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp
~ may light up
although the tyre pressures are correct. In this case, stop the vehicle as soon
as possible and, after examining the tyres, press the button for the tyre pres-
sure monitoring system.
Tyre ser vice life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.

Wheels and tyres
242Wear indicators
The original tyres on your vehicle have 1.6 mm high tread wear indicators
⇒ page 241, fig. 174 , 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
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the vehicle’s handling. The inflation pressures are listed on a
sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds. The
pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+)*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring system cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load and
stored accordingly in the tyre pressure monitoring system ⇒ page 240.
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 ⇒page 241, 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.•I f t y r e s s h o w e x ce s s i v e w e a r, y o u s h o u l d h a v e t h e r u n n i n g g e a r ch e cke d
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
3) the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESP/TCS (Electronic Stability Programme) switched on, or switch on ⇒page 68.
– 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 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 conditions, 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 the Electronic Stability Programme (ESP) is out of operation.•If the tyre pressure monitoring system* does not work.•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.

244•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.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. The
tyres and rims approved by SEAT are specially matched to the characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
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 designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
195 Tyre width in mm
65 Height/width ratio in %
RTyre construction: Radial
15 Rim diameter in inches 91 Load rating code
TSpeed rating
The tyres could also have the following information:
•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 an Authorised
Service Centre. They are familiar with the procedure and have the necessary
special tools and spare parts as well as the proper facilities for disposing of
the old tyres.
Any Authorised Service Centre has full information on the technical require-
ments when installing or changing tyres, wheels or wheel trims.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 six years old. If
you have no alternative, you should drive slowly and with extra care at all
times.•Never use old tyres or those with an unknown history of use.•If wheel trims are retrofitted, you must ensure that the flow of air to the
brakes is not restricted. This could cause them to overheat.•All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.

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 vehicles. 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 vehicle’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 - for example with 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
Wheel bolts must be tightened to the correct torque.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 218.
After the wheels have been changed, the tightening torque of the wheel bolts
s ho uld b e ch ecke d as so on as possi ble wi th a to rq ue wre nch. ⇒ The tight-
ening 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 torque of the wheel bolts is too low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening 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 tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicle’s
handling. The design of summer tyre s (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle’s regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
exeo_EN.book Seite 245 Montag, 30. August 2010 4:45 16

Wheels and tyres
246Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 244, “New tyres and wheels” determines the
following speed limits for winter tyres: ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
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 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 244, “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 may be fitted only to the front wheels, and only to certain tyre
sizes ⇒page 294.
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.
WARNING
Observe the fitting instructions provided by the snow chain manufacturer.
Caution
You must remove the snow chains to drive on roads which are free of 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.205/55 R16

Practical Tips
Technical Specifications
Your vehicle can be factory-equipped with a spare steel wheel. The spare
wheel does
not usually meet the same performance standards as the wheels
fitted on the vehicle because of the wheel/tyre dimensions, rubber composi-
tion, tread pattern, etc. Therefore, note the following restrictions:
•The spare steel wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.•Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒.•The spare wheel is only intended for temporary use after having a flat tyre.
Replace the spare wheel with a normal wheel that has the proper tyre dimen-
sions as soon as possible.•If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.WARNING
•After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The tyre pressure must corre-
spond to the vehicle load (consult th e table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.•Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.•Avoid heavy acceleration, hard braking and fast cornering, as this could
cause an accident.
Changing a wheelPreparation work
What you must do before changing a wheel.– 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 passengers should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
–Apply the handbrake firmly.
– Engage 1st gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒ page 247 out of the
luggage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning lights
and place the warning triangle in a visible location. This is for your own
safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
