Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating conditions.
We do, however, recommend that you have the electrolyte level inspected from
time to time by a Škoda Service Partner when outside temperatures are high or
when driving on long trips. You shou ld also check the electrolyte level ⇒page 220
each time the battery is charged.
The battery acid level will also be chec ked as part of the Inspection Service.
Operation in winter
The battery has to provide greater amounts of electricity during the winter. It also
has only part of the initial power output at low temperatures that it has at normal
temperatures.
A discharged battery may already freez e at temperatures just below 0°C.
We therefore recommend that you have the battery checked by a Škoda dealer
before the start of the winter, and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
Charging the battery
A properly charged battery is essential for reliably starting the
engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 218 and ⇒.
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all
“negative”, then “positive”). – Carefully attach the terminal clam
ps of the charger to the battery
terminals (red = “positive”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and switch on the charger.
– When charging is completed: switch the charger off and unplug the mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “nega-
tive”).
It is not normally necessary to disconnect the cables of the battery if you recharge
the battery using low amperages (as for example from a mini-charger). Please also
refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which should
be used until full ch arging is achieved.
It is, however, necessary to disconnect both cables before charging the battery with
high amperages, so-called “quick-charging ”.
“Quick-charging” a battery is dangerous ⇒ in “Working on the battery” on
page 218. It requires a special charger and appropriate knowledge. We therefore
recommend that you have yo ur battery quick-charged only by your Škoda Service
Par tner.
A discharged battery may already freeze at temperatures just below 0°C ⇒. We
recommend that you no longer use a ba ttery which has thawed out because the
casing of the battery may be cracked thro ugh the formation of ice and this would
allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.

Disconnecting and reconnecting the battery
On disconnecting and reconnecting the batte ry the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the ve hicle checked by a Škoda Service Partner to ensure
full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity, voltage
(12 V), amperage and of the same size. Škoda Service Partners have a range of suit-
able batteries available.
We recommend that you only have an old ba ttery disposed of by your Škoda dealer
since it does require special disposal.
For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. They must
be disposed of in accordance with loca l environmental protection regulations and
on no account as domestic waste.
Windshield washer system
The windshield washer reservoir contains the cleaning fluid for the windscreen or
rear window and for the headlamp cleaning system*. The reservoir is located at the
front right of the engine compartment ⇒fig. 203 .
The filling level of the container is 3 litres, 5.5 li tres on vehicles which also have a
headlight washing system.
Clear water is not sufficient to intensivel y clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessories (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your
vehicle is fitted with heated windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. Please note, however, that the antifreeze protection at this
concentration is only adequate down to -5°C.
WARNING
Read and observe the warning notes ⇒page 210, “Working in the engine
compartment” before working in the engine compartment.

General comments
•New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
•Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angles in order to avoid damage to tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequent ly not visible. Unusual vibrations or
pulling of the vehicle to one side could be a sign of tyre damage. Please reduce
your speed immediately and stop if you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulge s, splits, etc.) If no visible damage is
present, please drive at an appropriatel y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so th at their previous direction of running
can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
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 essential 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. Further information concerning
the use of unidirectional tyres ⇒page 227.
WARNING
•New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.
Tyre life
The life of your tyres very much depends on the following points:
Tyre 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.
Correctly inflated tyres are of partic ular 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 inflation pressures for summer tyres are indicated on the inside of the fuel
filler flap ⇒page 223, fig. 204 . The inflation pressures for winter tyres are 20 kPa
(0.2 bar) higher than those for summer tyres ⇒page 227.
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).
Always check the inflation pressure of ty res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your
vehicle is carrying a significantly higher payload.
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 influences
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 re ar will not only increase wear-and-tear
on the tyres but will also has an adverse effect on vehicle safety. Contact your
specialist garage if you notice any unusual tyre wear.
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.
•Immediately replace the damaged rims or tyres.
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 indicators are located at 6 - 8
points depending on the make and are evenly spaced around the circumference of
the tyre ⇒fig. 205 . Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identi fy 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
•You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn do wn. The legally permissible minimum
tread depth should be observed.
•Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncon-
trolled 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. 206 .
You will then obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyre s over “crosswise” when certain types of
wear characteristic ar ise on the running surface of the tyres (but not in the case of
unidirectional tyres). Škoda Service Pa rtners 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 therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are
exactly matched to the vehicle type and th erefore contribute significantly to good
road holding and safe driving characteristics ⇒.
Only fit radial tyres of the same type on all 4 wheels, size (rolling circumference)
and, if possible, the same tread pattern on one axle.
The Škoda Service Partners have access to the most current information about
which tyres we have released for use on your vehicle. We recommend that you have any work rela
ting to tyres or wheels carried out by
your Škoda Service Partner . Your dealer has all of th e necessary special tools and
replacement parts available plus the required specialist knowledge and is also in a
position to properly dispose of the old tyres. A large number of Škoda Service Part-
ners also have an attractive range of tyres and wheels available.
The tyre/wheel combinations which are appr oved for your vehicle are indicated in
your vehicle documents. Approval and lice nsing may differ according to the legis-
lation prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the correct type
of tyre. Tyres do, for example, have the following inscription on their walls:
195 / 65 R 15 91 T
What this means is:
The following speed restrictions apply to tyres.

means, for example, that the tyre was manufactured in the 20th week of the year
2007.
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 po ssible by a normal wheel.
WARNING
•Only use those tyres or wheel rims which have been approved for your
model of Škoda Auto a.s. 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.
•You must on no account drive at a higher speed than is permissible for
y our t yre s - ris k of a n ac cid e n t re su lti ng fro m ty re d a m ag e a nd lo ss o f c ont rol
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. Ty res 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 indivi dual 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.
For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regulations.
Note
It is not normally possible to fit wheels from other models of cars for technical
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 correct length and shape of
spherical cap. This is essent ial 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.
The Škoda Service Partners are instructed in the technical possibilities which exist
regarding converting or retrofitti ng wheels, tyres and wheel trim.
WARNING
•In case of incorrect treatment of th e wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
•The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
•If the wheel bolts are tightened to a too low tightening torque, the rim
can lossen when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in
permanent deformation of the contact surfaces on the rims.
Caution
The prescribed tightening torque of the wh eel bolts for steel and light alloy wheels
is 120 Nm.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Winter tyres
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber blend,
tread pattern). This partic ularly applies to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling char-
acteristics.
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 in flated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 223, fig. 204 .
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 ⇒page 225,
⇒ .
You can fit winter tyres of a lower speed ca tegory to your vehicle provided that you
also do not drive faster than the permis sible maximum speed for such tyres, even
if the possible maximum speed of your ve hicle is higher. The corresponding tyre
category can damage the tyres when exceeding the permissi ble maximum speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒page 223.
You can also fit so-called “all-year tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not clear who
will be able to provide you with information regarding the maximum speed for your
tyres.
WARNING
You must on no account drive your car at more than the permissible
maximum speed for your winter tyres - risk of an accident resulting from
tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good ti me since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-
tures below 7 °C - 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.
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 essential 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, lo w 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 dire ction or in opposite 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 233, “Spare wheel”.
You should have the defective tyre replac ed as soon as possible and restore the
correct direction of rotation on all tyres
Snow chains
Snow chains must only be mounted on the front wheels.
NKO A5 20 MR08.book Page 227 Wednesday, April 11, 2007 2:54 PM

Wheels and Tyres
228
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
For technical reasons, it is only permissi ble to fit snow chains with the following
wheel/tyre combinations:
Only use fine-link snow chains . They must not project more than 15 mm -
including the chain lock.
Remove the full wheel trims if you wish to fit snow chains to the wheels.
Observe the national legal requirements relating to the maximum vehicle speed
with snow chains.
WARNING
Please pay attention to the information in the supplied fitting instructions of
the snow chain manufacturer.
Caution
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.
Note
We recommend that you use snow chains from the Škoda genuine accessories.

Accessories, changes and replacement of parts
Accessories and replacement parts
Škoda vehicles have been built according to the latest discoveries in safety engi-
neering. Thus one should no t change the condition in which the vehicle was deliv-
ered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retrofitted with
accessories, have technical ch anges made to it or a par t has to be replaced at some
time in the future.
•Advise should always be obtained from a Škoda Service Partner before buying
any accessories and before making any technical changes ⇒.
•This is particularly the case when acce ssories are bought in a foreign country.
•Škoda Genuine Accessories which have b een released for use and Skoda orig-
inal parts can be obtained from Škoda Se rvice Partners. They will install them
professionally and correctly.
•All Škoda original accessory which is listed in the catalogue such as tilting roofs,
spoilers, wheels etc. must have an official stamp of approval.
•Radios, aerials and other electrical access ories should only be installed by an
authorised workshop.
•The guidelines issued by Škoda Auto a.s. must be observed when making tech-
nical 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
Service Partners 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 Skoda a.s. dealer is excluded from the guarantee.
WARNING
•We advise you, in your own interest, to only use Škoda Genuine Accesso-
ries and Škoda original parts which have been expressly approved for use on your Škoda. Reliability, safety and su
itabiliity have been established for
these Škoda original parts.
•We cannot guarantee suitability of installation into your vehicle of other
products despite keeping a constant ey e on market developments (also not
in the case where there is an attestation or permission can be produced).
Technical changes
Interference on the electronic components and their software can lead to opera-
tional faults. This interference can also impair not directly affected systems because
of the networking of the electronic co mponents. This means that the operating
safety of your vehicle can be considerably jeopardized, a greater wear of vehicle
parts can occur and finally the vehi cle registration documents expire.
We trust that you will understand that yo ur Škoda Service Partner cannot be liable
for damage resulting from unprofessional work.
We therefore recommend that you have a ll work carried out with Škoda original
parts at your authorised Škoda Service Partners.
WARNING
Work or modifications on your vehicle, which have been carried out unpro-
fessionally, can cause operational faults - risk of accident!
