WARNING
•The battery acid is strongly corrosive and must, therefore, be handled with the greatest of care. Always we ar protective gloves, eye and skin protection when handling batteries. Corrosive fumes in the air irritate the air passages and lead to conjunctivitis and inflammation of the air passages in the lungs. Battery acid corrodes dental enamel and creates deep wounds after contact with the skin which take a long time to heal. Repeated contact with diluted acids causes skin diseases (inflammations, ulcers, slin cracks). Acids coming into contact with water are diluted accompanied by significant development of heat.
•Do not tilt the battery otherwise battery electrolyte may flow out of the battery vent openings. Prot ect the eyes with safety glasses or a shield! There is the danger of suffering blindness! If any battery electrolyte gets into your eye, rinse out your eye immediately with clear water for several minutes. Contact a doctor without delay.
•Splashes of acid on your skin or clothes should be neutralised as soon as possible using soap suds and then rinsed with plenty of water. Contact a doctor immediately if you swallow battery electrolyte.
•Keep batteries out of the reach of children.
•Hydrogen is released when you char ge a battery and a highly explosive gas mixture is produced. An explosion can be caused through sparkling over during unclamping or loosening of the cable plug while the ignition is on.
•Bridging of the poles will create a short circuit (e.g. through metal objects, cables). Possible consequences of a short circuit: Melting of lead struts, explosion and burning of the battery, jets of acid spurting out.
•It is prohibited to work with a naked flame and light, to smoke or to carry out any activities which produce sparks. Avoid creating sparks when working with cables and electrical device s. Strong sparking represents a risk of injury.
•Before carrying out any work on the electrical system, switch off the engine, the ignition as well as all electrical components and disconnect the negative cable (-) on the battery. If you wish to replace a bulb it is sufficient to switch off the appropriate light.
•Never charge a frozen or thawed battery - risk of explosion and caustic burns! Replace a frozen battery.
•Never use a battery which is damaged - risk of explosion! Immediately replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched off, otherwise the electrical system (electronic components) of the vehicle may be damaged. When disconnecting the battery from the el ectrical system of the vehicle, first disconnect the negative terminal (-) of th e battery. Then disconnect the positive terminal (+).
•When reconnecting the battery, first conne ct the positive terminal (+) and only then the negative terminal (-) of the batt ery. You must on no account connect the cables wrongly - risk of a cable fire.
•Ensure that battery acid does not come into contact with the vehicle body otherwise damage could occur to the paintwork.
•Do not place the battery in direct daylight in order to protect the battery housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment - we recommend that you contact your Škod a Service Partner regarding disposing of the battery.
Note
•Please also refer to the guidelines ⇒page 185, “Disconnecting and recon- necting the battery”, also after connecting the battery.

Battery with a charge level indicator, the so-called magic eye*
There is a so-called magic eye ⇒fig. 162 located on the top of the battery. The “magic eye” changes its colour in line with the charge state of and electrolyte level in the battery.
Air bubbles can influence the colour of th e “magic eye”. For this reason carefully knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour - we reco mmend you have the battery checked by a Škoda Service Partner.
Batteries, which are more than 5 years old, must be replaced. We recommend you have the electrolyte level inspected and adjusted to the correct level or the battery replaced if necessary by a Škoda Service Partner.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will discharge because certain electrical comp onents consume electricity (e.g. control units) also in idle state. You can prevent the discharging of the battery by discon- necting the negative terminal or charging the battery constantly with a very low charging current. Please also refer to the notes when working on the battery ⇒ page 182, “Working on the battery”.
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 should also check the electrolyte level ⇒page 184 each time the battery is charged.
The battery acid level will also be ch ecked 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 Service Partner before the start of the winter, and recharged if necessary.
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 182 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.

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 191.
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 187, fig. 164. The inflation pressures for winter tyres are 20 kPa (0.2 bar) higher than those for summer tyres ⇒page 190.
The tyre pressure should be at the highest pressure specified for your vehicle at all times.
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. 165. 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 coul d 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. 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.
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 the necessary special tools and replacement parts available plus the requir ed specialist knowledge and is also in a position to properly dispose of the old ty res. 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:
185 / 65 R 14 86 T
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 ... 05 07...
means, for example, that the tyre was manufactured in the 40th 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 the 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.
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 applies in particul ar to vehicles which are equipped with low- profile tyres or high-speed tyres (code index H, V or W 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 187.
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 189, ⇒ .
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 ex ceeding the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒page 187.
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 time 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 shor ter, 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 196, “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.
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 9 mm - including the chain lock.

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 accessories are bought in a foreign country.
•Škoda Genuine Accessories which have been 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 accessories 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!
