•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving uphill or downhill),
•the vehicle is operated in unfavourable winter conditions or on an unfirm ground,
•snow chains or emergency wheel are mounted,
•the driver has a sporty style of driving (with sharp acceleration and high speed when cornering).
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels, a basic setting of the system must be carried out as follows.
•Inflate all tyres to the specified inflation pressure ⇒page 187.
•Switch on the ignition.
•Press button   ⇒page 150, fig. 147 for more than 2 seconds. While pressing the button, the warning light  lights up. At the same time the basic values are stored, which is confirmed with an acoustic sound and then the warning light  goes out.
•If the warning light  does not go out after the basic setting, there is a fault in the system. Have the vehicle inspected by your nearest specialist garage.
Function description
After the basic setting of the system the “a daptation” of the tyre inflation pressures and then the tyre pressure control in the individual tyres are performed.
Warning light  lights up
If the tyre inflation pressure of at least on e wheel is insufficiently inflated in compar- ison to the stored basic value, the warning light  ⇒ lights up. Inflate all tyres to the specified inflation pressure ⇒page 187, “Tyre life” and then perform a basic setting of the system.
WARNING
•When the warning light  lights up, immediately reduce the speed and avoid sudden steering and brake mano euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their inflation pressures.
•The driver is responsible for the correc t tyre inflation pressures. For this reason, the tyre inflation pressures must be checked regularly.
•Under certain circumstances (e.g. sporty style of driving, wintry or unpaved roads) the warning light  can be delayed or does not light up at all.
•The tyre inflation pressure-control system does not take away the responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflatio n pressure control, because the system cannot detect an even pressure loss,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of sudden tyre damage. In this case carefully bring the vehicle to a standstill without sudden steering movements and without sharp braking.

should be attached to folding arms. Adjust the mirrors so that they provide you with an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th e aid of the headlight beam adjuster ⇒ page 46.
Detachable ball head
The ball rod is detachable on vehicles with towing device and suppliable from Škoda original accessories. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle.
Note
•We recommend that you also have yo ur vehicle inspected between service intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling and decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– Do not, as far as possible, drive with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temper ature gauge if the outside temper-
ature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is laden. Maintain a particularly low speed if you cannot avoid driving with this combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind conditions, particularly near accident black spots.
You must always reduce your speed immedi ately as soon as you detect even just the slightest swaying of the trailer. On no account attempt to stop the trailer from “swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the brakes gently at first and then brake firmly . This will avoid brake jolts resulting from the trailer wheels locking. Shift down gears in good time before negotiating a down- hill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engine speed when the outside temperature is very high ⇒page 10.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo ur speed immediately. Stop and switch off the engine if the warning light  in the instrument cluste r begins flashing. Wait a few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 179, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 24, “Coolant temperature/coolant level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible since the fan speed is independent

Taking care of your vehicle and cleaning the vehicle164
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed normally in automatic vehicle wash plants without any problem. The actual stress to which the paintwork is subjected, howeve r, depends primarily on the design of the vehicle wash system, the filtering of th e water and the type of washing and care products used. If the paintwork of your vehicle appears mat after being washed or even has scratches, point this out to the operator of the vehicle wash plant. Use a different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant other than the usual precautionary meas ures (closing windows, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck system, two-way radio aerial - it is best to first of all consult the operator of the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor- oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or a washing brush and only slight pressure. Work from the top to the bottom - beginning with the roof. Only place slight pressure on the vehicle paintwork during cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle - risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you are cleaning the underfloor, the inside of the wheel housings or the wheel trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough kitchen sponges or similar cleaning prod- ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This ensures that no water which may be cont aminated by oil flows into the sewage system. It is not even permitted to wash your vehicle in certain areas except at such specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pre ssure cleaner, it is essential to comply with the instructions for use of the cleaning equipment. This applies in particular to the pressure used and to the spraying distance. Maintain a sufficiently large distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!

Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving your vehicle its regular wash. This prevents an y brake dust, dirt and road salt from sticking to the wheel hubs. You can remove stubborn brake abrasion adhering to t h e w h e e l s w i t h a n i n d u s tr i a l c l e a n e r. To u c h u p a n y d a m a g e to t h e p a i n tw o r k o n th e wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their decorative appearance over long periods. It is partic ularly important to remove any road salt and brake abrasion from light alloy wheels every two weeks, otherwise the surface will suffer. Wash thoroughly and then treat the wheels with a protective product for light alloy wheels which does not contain any acidic components. You should provide the wheel hubs with a hard wax la yer every three months. You must not use any products which cause abrasion when treating the wheel hubs. Any damage to the paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from Škoda genuine accessories offered by your Škoda dealer.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road salt may adversely affect braking ef ficiency - risk of an accident!
Note
Severe layers of dirt on the wheels can also result in wheel imbalance. This may show itself in the form of a wheel vibration which is transmitted to the steering wheel which, in certain circumstances, ca n cause premature wear of the steering. This means it is necessary to remove the dirt.
Underbody protection
The underside of your vehicl e is protected for life against chemical and mechanical influences.
One cannot, however, completely rule out damage to the protective layer when driving so we recommend that you inspect the protective layer on the underside of your vehicle and on the chassis at certain in tervals - this is best done at the begin- ning and end of the winter - and to touch up any damaged areas.
Škoda Service Partners have suitable spray products available as well as the neces- sary equipment and are familiar with the instructions for use. We therefore recom- mend to have repairs and additional co rrosion protection measures preferably carried out by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalytic converte rs, heat shields or diesel particle filter*. When the engine reaches its operating temperature, these substances might ignite - risk of fire!
Protection of hollow spaces
All the cavities of your vehicle which are at risk from corrosion are protected for life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any small amount of wax which flows out of the cavities at high temperatures with a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental protection regulations should observed when using petroleum cleaner to re move wax - a risk of fire!

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.
