– Please also refer to the notes when working on the battery ⇒page 212.
– Switched off all electrical components and remove the ignition key.
– Pull off gasket and take out the cover of the plenum chamber in the direction of the arrow ⇒fig. 161 .
– Unclamp the battery negative terminal (-).
– Unclamp the battery positive terminal (+).
– Unscrew the screw ⇒fig. 162 completely and remove the
locking plate.
– Move the battery in the direction of the arrow and pull it out in an upward direction.
– Installation takes place in the reverse order.
Please also refer to the following notes when connecting up the battery
⇒ page 216.
Note
We do not recommend that you remove and install the battery yourself
(even when you are following the instructions given in this manual) since
a battery can be heavily damaged in the process under certain circum-
stances. Please contact your Škoda dealer.
Disconnecting and reconnecting the battery
On disconnecting and reconnecting the battery the following functions are
initially deactivated or are no longer able to operate fault-free.
We recommend having the vehicle checked by a Škoda dealer 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 dealers have a
range of suitable batteries available.
We recommend that you only have an old battery disposed of by your
Skoda 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 local environmental protec-
tion regulations and on no account as domestic waste.

Windscreen Wiper and Washer System
The windshield washer reservoir contains the cleaning fluid for the wind-
screen and for the headlamp cleaning system*. The reservoir is located at
the front left of the engine compartment ⇒fig. 163 .
The reservoir has a capacity of 4 liters.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We therefore recommend using clean washing water together with
the screen cleaner (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 methyl-
ated spirits must not be more than 15 %. Please note, however, that the
antifreeze protection at this concentration is only adequate down to -5°C.
Caution
•On no account should you add radiator antifreeze or other additives to
the windscreen washer fluid.
•If the vehicle is fitted with headlight cleaning system, you should only
add cleaning products which do not attack the polycarbonate coating of
the headlights to the windscreen washer fluid. Please contact a Škoda
dealer, he will tell you, which cleaning product you can use.
Note
Do not take the filter out of the windscreen wash container when filling it
up again with liquid otherwise dirt can get into the liquid transportation
system and can lead to faults in operation of the windscreen wash
system.
Spark plugs
The spark plugs will also be checked as part of the Inspection Service.
Please observe the following if spark plugs have to be renewed inbetween
inspection services.
•Spark plugs and the ignition system are matched to the engine and
therefore contribute to lower emissions in the exhaust gases.
•Only use the spark plugs foreseen for the engine concerned if you wish
to avoid operational faults, engine damage and loss of approval and
licensing of the vehicle due to false exhaust gas values or unshielded
spark plugs. Particularly important parameters include the number of elec-
trodes, the thermal value and possibly also the radio frequency suppres-
sion level.

Spark plugs are constantly being further developed. It is therefore advis-
able to just obtain spark plugs from Skoda dealers since they are informed
about latest developments.
V-ribbed belts
The V-ribbed is one of the most highly loaded components on a vehicle.
This is why there are high demands on quality made on the V-ribbed belt.
It not sufficient when replacing the V-ribbed belt to choose just any one of
the same size. One should only use the V-ribbed belt foreseen for use
on that vehicle for safety reason.
V-ribbed belts are constantly being further developed. It is therefore advis-
able to just obtain them from Skoda dealers since they are informed about
latest developments.
The dust and pollen filter*
The dust and pollen filter for the heating and ventilation system is located
in the heater. The filter is replaced according to directions given in the
Service Plan. The filter should be replaced even earlier when the air flow
is reduced significantly.
Changing of the filter is undertaken by a Skoda dealer as part of the
inspection service.

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 frequently not visible. Unusual vibra-
tions 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 (bulges,
splits, etc.) If no visible damage is present, please drive at an appropri-
ately slow speed and carefully to the nearest Škoda dealer 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 that 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. Please comply with any national regulations in other countries which may
differ from the information stated above.
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 225.
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 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.
Fig. 166 Tyre tread
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 following
speed restrictions apply to tyres.
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.
