Tyre life
The life of your tyres very much depends on the following points: Tyre inflation pressure
The working life of tyres will be shortened considerably if the tyres are
insufficiently or over-inflated and this will have an adverse effect on the
handling of your vehicle.
Check the inflation pressure of the tyres at least once a month. The tyre
inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap ⇒fig. 164 . The inflation pressures for winter tyres are 0.2
bar higher than those for summer tyres ⇒page 224.
Correctly inflated tyres are of particular importance when travelling at high
speeds. It is therefore good to check the pressure at least once a month
and also before setting off on a long trip. Please do not forget the spare
wheel when checking the tyres.
The tyre pressure should be at the highest pressure specified for your
vehicle at all times.
On cars with full wheel trim, valve extensions are fitted in place of dust
caps ⇒fig. 165 . It is not necessary to unscrew the valve extensions in
order to check and alter the inflation pressure of the tyre.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase
wear-and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influ-
ences when driving which may result in an imbalance and which makes
themselves felt through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases
wear-and-tear on the steering, the suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted and each time a tyre is
repaired.

Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-
and-tear on the tyres but will also has an adverse effect on vehicle safety.
Contact your Škoda dealer if you notice any unusual tyre wear.
For the sake of
the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm
high, installed at right angles to the direction of travel. These wear indica-
tors are located at 6 to 8 points depending on the make and are evenly
spaced around the circumference of the tyre ⇒fig. 166 . Markings on the
walls of the tyres through the letters “TWI” or triangular symbols identify
the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread
next to the wear indicators, means that your tyres have reached their
legally permissible minimum tread depth.
WARNING
If the inflation pressure is too low, the tyre must perform a greater
flexing work. At higher speeds the tyre will warm up as a result of
this. This can result in tread separation and even a tyre blowout.

with wear indicators
WARNING
•You must have your tyres replaced with new ones at the latest
when the wear indicators have been worn down. The legally
permissible minimum tread de pth should be observed.
•Worn tyres do not provide the necessary adhesion to the road
surface at high speeds on wet roads. One could experience “aqua-
planing” (uncontrolled movements of the vehicle - “swimming” on
a wet road surface).

Changing wheels around
If significantly greater wear is present on the front tyres, we recommend
changing the front wheels around with the rear wheels as shown in the
diagram ⇒fig. 167 . You will then obtain approximately the same life for
all the tyres.
It may be advantageous to swap the tyres over “crosswise” when certain
types of wear characteristic arise on the running surface of the tyres (but
not in the case of unidirectional tyres). Škoda dealers can provide you with
details.
We recommend that you change the wheels around every 10 000 km in
order to achieve even wear on all wheels and to obtain optimal tyre life.
New tyres and wheels
Tyres and wheel rims are important design elements. One should there-
fore use the tyres and wheel rims which have been released for use by Škoda Auto. They are exactly matched to the vehicle type and therefore
contribute significantly to good road holding and safe driving characteris-
tics
⇒ .
Only fit radial tyres of the same type on all 4 wheels of the same type, size
(rolling circumference) and, if possible, the same tread pattern.
Škoda dealers have access to the most current information about which
tyres we have released for use.
We recommend that you have any work relating to tyres or wheels carried
out by your Škoda dealer . Your dealer has all of the necessary special
tools and replacement parts available plus the required specialist knowl-
edge and is also in a position to properly dispose of the old tyres. A large
number of Škoda dealers also have an attractive range of tyres and
wheels available.
The tyre/wheel combinations which are approved for your vehicle are indi-
cated in your vehicle documents. Approval and licensing may differ
according to the legislation prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the
correct type of tyre. Radial tyres have, for example, the following inscrip-
tion :
205 / 60 R 15 91 V
What this means is:

The date of manufacture is also stated on the tyre wall (possibly only on
the inside of wheel):
DOT ... 30 01...
means, for example, that the tyre was manufactured in the 30th week of
the year 2001.
Any spare wheel which differs from the tyres fitted to the vehicle (e.g.
winter tyres or low-profile tyres) should only be used only for a short time
in the event of a puncture and when adopting an appropriately cautious
style of driving. It should be replaced as quickly as possible by a normal
wheel.
For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regula-
tions.
Note
It is not normally possible to fit wheels from other models of cars for tech-
nical reasons. This may also apply in certain circumstances to the wheels
of the same type of vehicle.
Wheel bolts
Wheels and wheel bolts are matched to each other in terms of design.
Each time you fit other wheels - e.g. light alloy wheels or wheels with
winter tyres - you must therefore also use the matching wheel bolts of the

WARNING
•Only use those tyres or wheel rims which have been approved
for your model of Škoda Auto vehicle. Failure to observe this
instruction will adversely affect the road safety of your vehicle -
risk of accident! Approval and licencing of your vehicle on public
roads may also become void as a result.
WARNING (continued)
•You must on no account drive at a higher speed than is permis-
sible for your tyres - risk of an accident resulting from tyre damage
and loss of control over your vehicle.
•Tyres which are 6 years old or more should only be fitted in
exceptional cases and when adopting an appropriately cautious
style of driving.
•Never fit tyres which have already been used without having
adequate knowledge of their previous history. Tyres age even if
they have not been used at all or only very little. A spare tyre must
only be used in exceptional cases and only then when adopting an
appropriately cautious style of driving.
•Do not, where possible, replace individual tyres but at least
replace them on both wheels of a given axle at the same time.
Always fit the tyres with the deeper tread depth to the front wheels.

correct length and shape of spherical cap. This is essential to ensure that
the wheels are tightly fitted and that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an
adequate flow of air remains assured for cooling the brake system.
Škoda dealers are instructed in the technical possibilities which exist
regarding converting or retrofitting wheels, tyres and wheel trim.
The wheel bolts must be clean and must turn easily.
Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads and at temperatures below 7 °C if you fit winter tyres.
Summer tyres do not offer the same grip on ice and snow because of their
construction (width, rubber blend, tread pattern). This applies in particular
to vehicles which are equipped with low-profile tyres or high-speed
tyres (code index V, W or Y on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
Only use radial winter tyres.
You must only fit those types of winter tyre which are approved for your
vehicle. The permissible sizes of winter tyres are stated in your vehicle
documents. Approvals may differ because of national legislation.
Please remember that the tyres should be inflated to 0.2 bar more than is
the case for summer tyres ⇒page 220.
Winter tyres no longer offer the same winter performance once the tyre
tread has worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance
properties - even in cases where the remaining tread depth is still clearly
more than 4 mm. Speed restrictions
apply to winter tyres as well as to summer tyres
⇒ .
You can fit winter tyres of a lower speed category to your vehicle provided
that you also do not drive faster than the permissible maximum speed for
such tyres, even if the possible maximum speed of your vehicle is higher.
Exceeding the speed category of the tyre can lead to damage occurring.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 219.
You can also fit so-called “all-weather tyres” instead of winter tyres.
Please contact your Škoda dealer If there are any points which are not
clear who will be able to provide you with information regarding the
maximum speed fo r your tyres.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you
better grip and handling on roads which are free of snow and ice - the
braking distance is shorter, there is less tyre noise, tyre wear is reduced
and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
WARNING
You must on no account drive your car at more than the permis-
sible maximum speed for your winter tyres - risk of an accident
resulting from tyre damage and loss of control over your car.

Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of
the tyre . This indicates the direction of rotation of the tyre, and it is essen-
tial that the tyres are fitted on to run in this direction. Only then are the
tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a
tyre not dedicated to the running direction, please adopt a cautious style
of driving as the tyre is no longer able to provide optimal grip and handling
in such a situation. This particularly important on wet roads. Please refer
to the notes ⇒page 229.
You should have the defective tyre replaced as soon as possible and
restore the correct direction of rotation on all tyres
Snow chains
Snow chains can be used only for wheel sizes 6J x 16 ET 40 or 6J x 16
ET 37. Your Škoda Dealer can provide you with more detailed information.
Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but
also the braking performance.
Only use fine-link snow chains . They must not project more than 15 mm
- including the chain lock.
Remove the full wheel trim if you wish to fit snow chains to the wheels.
You must take the chains off as soon as you drive on roads which are free
of snow. They adversely affect the handling of your vehicle, damage the
tyres and are rapidly destroyed. Observe the national legal requirements relating to the maximum vehicle
speed with snow chains.
Note
We recommend that you use snow chains from the Škoda range of
genuine accessories.

Accessories, changes and replacement of parts

Accessories, changes an d replacement of parts
General
Škoda vehicles have been built according to the latest discoveries in
safety engineering. Thus one should not change the condition in which the
vehicle was delivered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retro-
fitted with accessories, have technical changes made to it or a part has to
be replaced at some time in the future.
•Advise should always be obtained from a Škoda dealer before buying
any accessories and before making any technical changes ⇒.
•This is particularly the case when accessories are bought in a foreign
country.
•Skoda accessories which have been released for use and original
Škoda parts can be obtained from Škoda dealers. They will install them
professionally and correctly.
•All original accessories which are listed in the catalogue such as tilting
roofs, spoilers, wheels etc. must have an official stamp of approval.
•Radios, aerials and other electrical accessories should only be
installed by an authorised workshop.
•The guidelines issued by Škoda Auto must be observed when making
technical changes.
•This is to ensure that no technical damage occurs to the vehicle, that
travelling and operating safety are maintained and that the chnages are
permissible. Škoda dealers undertake this work professionally or refer it
to an specialist company in special cases.
Any damage which is done caused by technical changes made
without consulting a Škoda Auto is excluded from the warranty.
WARNING
•We advise you, in your own interest, to only use Škoda acces-
sories and original Skoda parts which have been expressly
approved for use on your Škoda. Reliability, safety and suitabiliity
have been established for these parts.
•We cannot guarantee suitability of installation into your vehicle
of other products despite keeping a constant eye on market devel-
opments (also not in the case where there is an attestation or
permission can be produced).

Spare wheel
The spare wheel is stowed in the spare wheel well in the
luggage compartment below the floor covering.
The spare wheel lies in a well under the luggage compartment floor and
is fixed in place using special screws ⇒fig. 172 . One should check the air pressure in the spare wheel (at best when
generally checking the tyre air pressures - see sign on the fuel filler flap)
to ensure that the spare wheel is always ready to use.
Unidirectional tyres*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has
different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning sticker must not be concealed
(e.g. by the wheel trim).
•Do not drive with this spare wheel at more than 80 km/h - risk of acci-
dent. Avoid accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation
pressure of the standard tyres.
•Use this spare wheel only to reach the nearest service station as it is
not intended for continuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually
changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose
should be level.
WARNING
•The hexagon socket in the handle of the screwdriver is used for
fitting on the wheel bolts. Neve r use it for tightening the wheel
bolts because you will not be able to achieve the necessary tight-
ening torque with this tool - risk of accident!
•The factory-supplied lifting jack is only intended for your model
of vehicle. On no account attempt to lift a heavier vehicle or other
loads - risk of injury!
