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 169, “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 177, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒ page 203, “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.

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. 139 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.

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 47.
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.
•Keep the mechanism of the ball head of the towing device clean and take proper care of it with a suitable preservative.
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 178, “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 vehicle
General
Proper care retains the value of your vehicle.
Regular and proper care retains the value of your vehicle. It may also be one of the requirements for the acceptance of warran ty claims relating to corrosion damage and paint defects on the bodywork.
We recommend using a preservative from Škoda genuine accessories offered by your Škoda dealer. Please follow the instructions for use on the package.
WARNING
•Care products may be harmful to your health if not used according to the instructions.
•Always store care products in a safe place, out of the reach of children - risk of poisoning!
For the sake of the environment
•Always select environmentally-friendly pr oducts when purchasing vehicle care products.
•Do not dispose of residues of ca re products in domestic waste.
Care of the exterior of vehicle
Washing the vehicle
Frequent washing protects your vehicle.
The best protection for your vehicle agai nst harmful environmental influences is frequent washing and wax treatment. How often you should wash your vehicle depends on a wide range of factors, such as:
•Frequency of use,
•The parking situation (garage, below trees etc.),
•Season of the year,
•Weather conditions,
•Environmental influences.
The longer insect residues, bird droppings, tree sap, road and industrial dust, tar, soot particles, road salt and other aggressive deposits remain adhering to the paint- work of your vehicle, the more detrimental their destructive effect can be. High temperatures, such as those caused by in tensive sun's rays, accentuate this caustic effect.
It may therefore be necessary, in certain circumstances, to wash the car once a week . It may also be sufficient, however, to wash the car once a month followed by appropriate wax treatment.
It is essential to also thoroughly wash the underside of your vehicle at the end of the winter road salting and gritting period.
WARNING
When washing your vehicle in the wint er: Water and ice in the brake system can affect the braking efficiency - risk of accident!

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 converters or heat shields. Such substances might ignite when driving - 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!

designed for it ⇒page 172, fig. 146.
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the
bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock -
bonnet do not press down on it!
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when driving. One should therefore check that the lock has in fact engaged prop- erly after closing the bonnet.
•Stop your vehicle immediately while driv ing if you notice that the lock is not properly engaged and close the bonne t properly - risk of an accident!
Caution
•Before opening the bonnet, ensure that the arms of the windscreen wipers are correctly in place against the windscreen. Otherwise, there is a risk of damage to the paintwork.
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the engine compartment, e.g. inspecting and replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart- ment of your car is a hazardous area ⇒.
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a ma nual gearbox, move the gearshift lever into Neutral, or if it is fitted with automatic gearbox, move the selector lever into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Do not touch any hot engine parts - risk of burns!
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth when opening it as protection for your face, hands and arms from hot steam or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine compartment.
•If you wish to work under the vehicle, you must secure the vehicle from rolling away and support it with suitable supporting blocks: the car jack is not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the engine is running there is an additional risk from rotating parts (e.g. the V-

Radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electr ic motor and controlled by a thermostat according to the coolant temperature.
The radiator fan may continue running fo r up to 10 minutes after the engine has been switched off - even if th e ignition is also off. It may also switch on suddenly after a certain time, if
•the coolant temperature has risen beca use of an accumulation of heat or
•the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when working in the engine compartment that the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
The brake fluid reservoir is located on the left of the engine compartment.
The brake fluid reservoir on right-hand steering models is positioned on
the other side of the engine compartment.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 173.
– Inspect the brake fluid level in the reservoir ⇒fig. 150. The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the brake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level drops significantly within a short time or if it drops below the “MIN” marking. A situ- ation where the brake fluid level is too low is indicated by the warning light lighting up in the instrument cluster ⇒page 28. In this case stop the car immedi- ately and do not drive any further! Contact a Škoda Dealer to obtain profes-sional assistance.
WARNING
•Read and observe the warning notes ⇒page 173, “Working in the engine compartment” before working in the engine compartment.
•If the fluid level has dropped below the MIN marking, do not drive any further - risk of accident! Contact a Škoda dealer to obtain professional assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture from the surrounding air over a period of time. Excessive water in the brake fluid may be the cause of corrosion in the brake system. Th e water content also lowers the boiling point of the brake fluid. This is why brake fluid must be replaced every two years.
