Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically controlled 6-speed automatic gearbox. Shifting up and also down through the gears is performed automatically.
At the same time this is a conventional automatic gearbox. The maximum speed is reached in the 5th gear. The 6th gear serves as an economic driving programme, which is intended to reduce the fuel consumption.
Information for driving with an automatic gearbox
Shifting up and down through the gears is performed automatically.
You can also, however, switch the gearbox over into the Tiptronic mode.
This mode makes it possible for you to also shift gears manually
⇒ page 100.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever),
move the selector lever into the desired position, e.g. D ⇒page 98,
and then release the Shiftlock button.
– Wait a moment until the gearbox ha s shifted (a slight engagement
nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected when stop-
ping just for a short time, such as at a cross roads. It is sufficient to hold
the vehicle stationary using the foot brake. The engine can, however,
be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector
lever to P and then release the Shiftlock button.
The engine can only be started when the selector lever is in position P or N ⇒ page 90.
It is sufficient to engage selector lever position P when parking on a flat surface. When parking on a slope you should first apply the handbrake firmly and then move the selector lever into position P. This is to ensure that there is no excessive pressure acting on the lock mechanism and that it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first neces- sary to release pressure on the accelerato r pedal and wait for idling speed of the engine to be reached before engaging a drive position in the selector lever.
WARNING
•Do not depress the accelerator when changing the position of the selector lever if the car is stationary an d the engine is running - risk of acci- dent!
•Never move the selector lever into position R or P when driving - risk of an accident!

gearbox does not shift up into the highest gear until the engine has reached its maximum revolutions for this gear range.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and down through the gears is performed auto matically on the basis of pre-defined driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most economical driving programme. Shifting up into a higher gear as soon as possible and shifting down as late as possible will have a favourable effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal combined with sharp acceleration and frequent changes in speed, exploiting the top speed of the car or depressing the a ccelerator pedal (kickdown function), will cause the gearbox to switch over to this style of driving and shift down earlier with frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving is a continuous process. Irrespective of this it is, however, possible to switch or shift down into a dynamic shift programme by depressing the accelerator rapidly. The gearbox shifts down into a lower gear matc hing the speed of the car and this allows you to accelerate rapidly (e.g. when ov ertaking) without having to depress the accelerator pedal fully into the kickdown range. The original programme will be reactivated to match your part icular style of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill sections. This avoids the ge arbox frequently shifting up and down when negotiating an uphill stretch. When driving downhill, it is possible to shift down into the Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
Switching over to manual shifting
– Push the selector lever to the right out of position D. As soon as the
gearbox has switched over, 6 5 4 3 2 1 appears in the display, with the
gear engaged being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)

Catalytic converter
Proper operation of the emission control system (catalytic converter)
is of major significance for drivin g your vehicle in an environmen-
tally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒ page 170, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 178, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒ page 205, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not available, you must have the catalytic converter replaced later when driving the vehicle into a country in which use of a cata lytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the catalytic converter, one should always park a vehicle in such a way that the catalytic converter cannot come into contact with easily flammable materials below the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalyti c converters or heat shields. Such substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter should never be allowed to let the fuel tank to run completely empty. An irregular fuel supply can result in poor ignition or
misfiring. Unburnt fuel may get into the exhaust system and damage the catalytic converter.
•Filling the tank even only once with le aded petrol will result in the catalytic converter being destroyed.
•If you detect misfiring, a drop in perf ormance or irregular engine running when driving, reduce your speed immediately and have the vehicle inspected by the nearest specialist garage. The symptoms described may be caused by a fault in the ignition system. Unburnt fuel may get in to the exhaust system and damage the catalytic converter.
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour may be produced under certain operating condit ions of the engine. This depends on the sulphur content of the fuel. It is often su fficient to refuel with unleaded premium- grade petrol of a different brand or at a different filling station.
Driving in an economical and environmentally
conscious manner
General
Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-and-tear to the engine, brakes and tyres, depend essentially on three factors:
•your personal style of driving,
•the conditions under which your vehicle is operated,
•technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving in an economical way with foresight. This section is intended to provide you with a number of tips on how to protect the en vironment and at the same time save money.

Driving and the Environment155
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
The fuel consumption can naturally also be influenced by factors which are beyond the driver's control. It is, for example, normal for the fuel consumption to increase in winter and under worsened conditions such as poor road conditions, towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the vehicle have already been built into the ve hicle at the works. Special attention has been given to minimising ne gative effects on the environment. It is necessary to take note of the guidelines given in this chapter in order to make best use of these characteristics and to maintain their effectiveness.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and brakin g unnecessarily. If you drive with forsight you will not need to brake so often and will also then not have to accelerate so much. Let your vehicle coast to a stop, for example, if this is possible, when you see that the next set of traffic lights is at red.
Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You will consume more fuel if you drive at unnecessa rily high revolutions in any given gear.
The ⇒fig. 149 shows the ratio of fuel consumption to the speed of your vehicle in the relevant gears. Fuel consumption in 1st gear is the highest and in 5th gear is the lowest.
Note
•The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption and resonance of the vehicle.
•Also use the information supplied by the multi-functional indicator* ⇒ page 13.
Avoiding full throttle
Driving more slowly means saving fuel.

Fig. 150 Fuel consump-tion in litres/100 km. and speed in km/h.
NKO A05R 20 MR08.book Page 155 Wednesday, March 28, 2007 9:42 AM

Driving and the Environment156
Sensitive use of the accelerator will not only significantly reduce fuel consumption but also positively influence environmen tal pollution and wear of your vehicle.
You should avoid fully exploi ting the top speed of your vehicle wherever possible. Fuel consumption, pollutant emissions and vehicle noises increase disproportion- ally at high speeds.
The ⇒page 155, fig. 150 shows the ratio of fuel consumption to the speed of your vehicle. You will cut your fuel consumption by half if you only make use three-quar- ters of the possible top speed of your vehicle.
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level crossing or at traffic lights with a length y red phase. Even after just 30 - 40 seconds you will have saved more fuel than that is needed when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operating temperature. Wear-and-tear and pollutant em issions, though, are particularly high in the warming-up phase. This is why you should drive off right after starting the engine. Do avoid high engine revolutions at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of
fuel.
Having your vehicle serviced regularly at a specialist garge enables you to satisfy one of the requirements for economical motoring even before you set off on your journey. Keeping your vehicle properly servic ed not only has a positive effect on the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fu el consumption which is 10% higher than normal.
The foreseen maintenance work should be undertaken exactly according to the Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid- erable extent on the load and speed of the engine. Oil consumption could be as high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine ha s a higher oil consumption at first, and reaches its lowest level only after a certain running in time. It is therefore not possible to correctly assess the oil cons umption of a new vehicle until after you have driven about 5 000 km.
For the sake of the environment
•You can achieve additional improvements in your fuel economy by using high- lubricity oils.
•Check the ground below your car at regula r intervals to detect any leakages in good time. Please have your vehicle inspected by a specialist garge if you find any stains caused by oil or other fluids on the floor.
Avoid driving short distances
Short distances result in an above-average high fuel consumption.
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating temperature in order to effectively reduce fuel consumption and pollutant emis- sions.
Fig. 151 Fuel consump- tion in litres/100 km at different temperatures
NKO A05R 20 MR08.book Page 156 Wednesday, March 28, 2007 9:42 AM

Driving and the Environment157
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediately after starting. Fuel co nsumption drops to 10 litres/100 km after just 1 kilometre. The engine reaches its operating temperat ure (outside temperature and engine dependent) only after about 4 to 10 kilometres and the fuel consumption then stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The ⇒ page 156, fig. 151 shows the different fuel consumptions for the same distance, on the one hand at +20°C and on the other hand at -10°C. Your vehicle has a higher fuel consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The rolling resistance will be increased if the tyre filling pressure is too low. This will not only increase fuel consumpt ion but also tyre wear and the driving behaviour will worsen.
Always check the inflation pressure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 % more fuel. Winter tyres are also louder.
No unnecessary ballast
Transporting balla st costs fuel.
The fact that every kilogram of extra weight increases your fuel consumption means that it is worth taking a look in the luggage compartment to avoid trans- porting any unnecessary ballast.
It is par ticularly i n town tra ffi c, whe n one is accelerating quite often, that the vehicle weight will have a significant effect upon the fuel consumption. A rule of thumb here is that an increase in weight of 100 kilograms will cause an increase in fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience, although you no longer need it. The incr eased aerodynamic drag of your vehicle
causes it to use about 1 l more fuel than normal at a speed of 100 - 120 km/h, even when you are not carrying a load on the roof.
Saving electricity
Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power. The greater the load on the alternator as a result of having a large number of elec-trical components switched on, the more fuel will be consumed for operating the alternator.
Keeping a log of your fuel consumption
If you really wish to keep a close check on your fuel consumption, it is best to enter the figures in a logbook. This does not take much time but is a very worthwhile exer-cise. It enables you to detect any change (positive and negative) at an early stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how, where and in what conditions yo u have driven the vehicle since you last refuelled.
Environmental compatibility
Environmental protection has played a major role in the design, selection of mate- rials and manufacture of your new Škoda. Particular emphasis has been paid to a number of aspects, including:
Design measures
•joints designed to be easily detached
•simplified disassembly due to the modular structure system
•improved purity of different classes of materials
•Identification of all plastic parts in accordance with VDA Recommendation 260

Trade-in and recycling of old cars
Škoda Auto meets the requirements of the brand and its products regarding envi- ronment and ressource protection. All new Škoda vehicles can be utilized up to 95 % and always 4) be returned. In a lot of countries sufficient trade-in networks have been created, where you can trade-in your vehicle. After you trade-in your vehicle, you will receive a confirmation stating the recycling in accordance with environmental regulations.
Vehicles with special built-on types
Technical documents regarding changes carried out on the vehicle must be kept by the vehicle user, in or der to hand over later to the old car user. This ensures the recycling in accordance with environmental regulations.
Note
Detailed information about the trade-in and recycling of old cars is available from your Škoda Service Partner.
Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in ce rtain countries, that the Škoda Service Partner network is limited or has not been established yet. This is the reason why obtaining certain spare parts may be somewhat complicate d and specialist garage personnel may only be able to ma ke li mite d re pa irs. Škoda Auto a.s. i n the Czech Republic and rele - vant importers are happy to provide info rmation about technical aspects of the vehicle, required maintenance work and possibilities for getting repairs done.
Unleaded petrol
A vehicle fitted with a petrol engine must always be refuelled with unleaded petrol ⇒ page 154. The automobile associations can provide you with information regarding the locations of filling stations which offer unleaded petrol.
Headlights
The low beam of your headlights is set asym metrically. It illuminates the side of the road on which you are driving to a greater extent. If you drive abroad on the other side of the road, you wi ll dazzle oncoming traffic.
It is necessary in order to avoid dazzling oncoming traffic to stick a sticker over a certain part of the headlights.
Headlight stickers can be obtained as a spare part from the Skoda Service Partners.
Headlights with module are designed for driving in countries with traffic on the right or on the left. Have this done always at a Škoda Service Partner.4)subject to fulfilment of the national legal regulations

Fuel170
Fuel
Petrol
Grades of petrol
There are various grades of petrol. Please read ⇒page 223, “Technical Data” in order to know which grade of petrol your vehicle requires. You will also find the same information affixed to the inside of the fuel filler flap of your vehicle ⇒ page 171, fig. 153.
A distinction is made betwee n unleaded and leaded petrol. All Škoda vehicles with petrol engines are equipped with a cataly tic converter and must therefore be only driven with unleaded petrol. Unleaded petrol complies with the standard DINEN228 .
The individual grades of petr ol are distinguished by their octane number (RON). Please adopt the following procedure if th e grade of petrol which you normally use is not be available in exceptional circumstances:
•Engines which need unleaded premium petrol 95 RON can also be run on unleaded regular petrol 91 RON. This does, however, result in a slight loss in performance.
•Engines which need unleaded premium plus petrol 98 RON can also be run on unleaded regular petrol 95 RON. This do es, however, result in a slight loss in performance. You can in exceptional circumstances also use unleaded regular petrol of 91 RON in the event that neither unleaded premium petrol of 98 RON nor 95 RON is available. Refuel as soon as possible with unleaded premium plus of 98 RON or unleaded premium petrol of 95 RON.
If, in an emergency, the only fuel availa ble is one which has a lower octane number than that required by the engine then only drive at medium engine speeds and lower engine loadings.
You can make unlimited use of fuel which has a higher octane number than that required by the engine. There will, however, be no advantages gained by this in terms of engine performa nce and fuel consumption!
The handling, performance and life of your engine are determined to a significant extent by the quality of the fuel. Do not use any petrol additives. Use a fuel complying with the standard.
You can find further information on refuelling ⇒page 171.
Caution
•Filling the tank even only once with leaded petrol will result in the catalytic converter being destroyed.
•Operating the engine with petrol of a low octane number than that required can result in engine damage at high revolutions or severe engine loading.
Diesel
Diesel fuel
Your vehicle can be operated with diesel fuel, which complies with the standard EN 590 .
Fuel additives
You must not use fuel additives, so-ca lled “flow improvers” (petrol and similar products) in diesel fuel.
If the quality of the diesel fuel is p oor, it is then necessary to drain the fuel filter more often than stated in the Service schedule.
You can find information on refuelling ⇒page 171, “Refuelling”.
Caution
•Use a fuel which complies with the standard EN 590. Filling the tank even only once, which does not comply with the stan dard, can result in damage to the fuel system.
•Water which has collected in the fuel filter can result in engine problems.

Check engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 174.
– Wait a few minutes and pull out the oil dipstick ⇒.
– Wipe off the dipstick with a clea n cloth and insert it again fully.
– Then withdraw the dipstick ag ain and read off the oil level.
Oil level within range
– You must not top up the oil.
Oil level within range
– You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil. It is sufficient, once this is done, to keep the
oil level is within range .
It is normal for the engine to consume oi l. The oil consumption may be as much as 0.5 l/1 000 km depending on your style of driving and the conditions under which you operate your vehicle. The oil consumpt ion may be slightly higher than this during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been operating at high loads, for example during a lengthy motorway trip during the summer months, towing a trailer or negotiating a high mountain pass, but not above this .
The warning light in the instrument cluster* will indicate ⇒page 25 whether the oil level is too low. In this case, check the oil level as soon as possible. Top up with an appropriate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 174, “Working in the engine compartment” before working in the engine compartment.
Caution
•Always check the oil level on vehicles with engine 1.2 l/51 kW when the engine is warm. Otherwise the measuring result is incorrect und oil could be incorrectly replenished - risk of engine damage!
•The oil level must on no account ex tend beyond the range . Danger of damaging the cata lytic converter.
•Do not continue your journey if for some reason it is not possible under the conditions prev ailing to top up with oil. Switch the engine off and obtain profes- sional assistance from a specialist garage, otherwise it could lead to severe engine damage.

Wheels and Tyres188
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).
