Tyre service life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.
Wear indicators
The original tyres on your vehicle ha ve 1.6
mm h igh “tre
ad wear indicators"

⇒

fig. 143 running acro ss the tread. Depending on the make, the re will be
six to eight of them evenly spaced around the tyre. Markings on the tyre side-
wall (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 indicators).
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 210.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably mo re than the rear ones it is advisable
to change them around as shown ⇒fig. 144 . 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.New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essenti al 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 kn owledge 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 %
R Tyre construction: Radial
15 Rim diameter in inches
91 Load rating code
T Speed rating
The tyres could also have the following information:
•
A direction of rotation symbol
•
“Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicate d 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 is 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.

Checking and refilling levels
214Information 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.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 212, “New tyres and wheels” determines the
following speed limits ⇒ :
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 212, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyres must not be exceeded. Otherwise,
this could lead to tyre damage and thus, an accident risk.
For the sake of the environment
Fit your summer tyres in good time. 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 250.
Snow chains must have fine-pitch link s which do not protrude more that 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.
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.

222Anti-theft wheel bolts
A special adapter is required to turn the anti-theft wheel
bolts.– Insert the adapter onto the wheel bolt and push it on as far as it
will go ⇒fig. 151 .
– Fit the box spanner as far as it will go over the adapter.
– Loosen or tighten the wheel bolt as appropriate.Code number
The code number of the anti-theft wheel bolt is stamped on the front of the
adaptor.
The code number should be noted and kept in a safe place, as it is only by
using the code number that a duplicate adaptor can be obtained from an
Authorised Service Centre.
Tyres with directional tread pattern
Tyres with directional tread pattern must be fi tted s o tha t they
rotate in the correct direction.A directional tread pattern can be identified by arrows on the sidewall that
point in the direction of rotation. Always note the direction of rotation indi-
cated when fitting the wheel. This is important so that these tyres can give
maximum grip and avoid excessive noise, tread wear and aquaplaning.
If, in an emergency, you have to mount the spare wheel so it rotates in the
wrong direction, you must drive extremel y carefully. The tyre will not give
optimum performance. This is particularly important when driving 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 direction.Tyre repair kit (Tyre-Mobility-System)*General information and safety notesYour vehicle is equipped with a tyre repair kit: the Tyre Mobility System.
In the event of a tyre puncture, sealing compound and an air compressor are
located in the luggage compartment under the floor panel.
The Tyre Mobility System will reliably seal punctures caused by the penetra-
tion of a foreign body of up to about 4 mm in diameter.
It is not necessary to remove the foreign body from the tyre.
Instructions for the sealing compound are located on the sealing compound
container.

Fuse cover underneath the steering wheel
– Switch off the ignition and the component concerned.
– Identify the fuse for the failed component ⇒page 226.
– Take the plastic clip from inside the fuse cover, fit it onto the blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
Fuse cover in engine compartment
– Switch off the ignition and the component concerned.
– Prise off the fuse cover in the engine compartment by pressing the tabs towards the centre of the cover ⇒page 224, fig. 153 .
– Identify the fuse for the failed component ⇒page 226.
– Take the plastic clip from inside the fuse cover (at left-hand end of the dash panel), fit it onto the blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same ampere rating.
– Carefully fit the fuse cover back on to ensure no water can enter the fuse box.The individual electrical circuits are pr otected by fuses. The fuses are located
behind a cover at the left-hand end of the dash panel and on the left-hand
side of the engine compartment.
The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected. Colour coding of fuses
WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could re
sult in fire. This could also cause
damage to other parts of the electrical system.
Note
•
If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualified workshop as soon as possible.
•
If you replace a fuse with a stronger fuse, you could cause damage to
another location in the electrical system.
•
Always keep some spare fuses in the vehicle. These are available from
official Service. Colour

Bulb changeGeneral notesBefore changing any bulb first turn off the equipment concerned.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the same type. The type is inscribed
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the bulbs that most affect road safety should have spares in the
vehicle.

change the bulbs except for the fog lights and interior bulbs.
19)For these type of headlights, the bulbs must be changed by an Authorised Service
Centre, given that complex elements of the vehicle must be removed and that the au-
tomatic control system must be reset.20)Xenon bulbs discharge emit 2.5 times as much light flux and have a useful life five
times greater than halogen bulbs.

How are the figures measured?Fuel consumptionFuel consumption and emission values are determined according to Euro-
pean Commission Directive 99/100/EC. They take the actual kerb weight
(weight class) into consideration. To calculate the consumption rate, two measuring cycles are carried out on a rolling road test bed. The test criteria
are as follows:
Note
•
The fuel consumption and emission values quoted in the tables below are
based on an empty basic vehicle without optional extras. The kerb weight of
the vehicle may vary depending on the equipment fitted and thus the weight
category with a relative increase of consumption and emission of CO
2 Your
Authorised Service Centre will be able to inform you of the figures which apply
to your vehicle.
•
Actual consumption may vary from quoted test values, depending on
personal driving style, road and traffic conditions, the weather and the condi-
tion of the vehicle. Urban cycle
The urban cycle starts with an engine cold start. City driving is then simulated.
Extra urban cycle In the extra urban cycle the vehicle undergoes frequent acceleration
and braking in all gears, as in normal everyday driving. The
road speed ranges from 0 to 120 km/h.
Combined The average overall consumption is calculat
ed with a weighting of around 37% for the urban cycle and 63% for the extra urban
cycle.
CO2 emissions The exhaust gases are collected during both driving cycles to calculate carbon dioxide emissions. The gas composition is then
analysed to evaluate the CO
2 content and other emissions.

Snow chains
Snow chains may be fitted only to the
front wheels.
Consult the chapter “wheels” of this manual.
Wheel bolts
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 tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
•
Check the tyre pressure at least once per month. Correct 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.
•
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 could be damaged.Note
We recommend that you ask your Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size.
