The TCS should normally always be switched on. It may be good practice in certain exceptional cases, such as when you wish to have wheel slip, to switch off the system.
Examples:
•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-free operation of the TCS. Differing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-ment of tyres and wheels) can influence the function of the TCS ⇒page 200, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automatically, that is without any action on the part of the driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only one drive wheel begin spinning on a slippery surface there will be an appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to avoid excessive heat generation in the disc brake on the wheel which is being braked. The vehicle can continue to be driven and has the same characteristics as a vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slip-pery road surfaces, such as ice and snow. The driven wheels might still spin despite the EDL and affect the stability of the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition of road surface and to the traffic situation even when your vehicle is fitted with EDL. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in the EDL. Please have the car inspected as soon as possible by a specialist garage.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-ment of tyres and wheels) can influence the function of the EDL ⇒page 200, “Accessories, changes and replacement of parts”.

Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces-sary to have the thickness of the brake pads inspected at a specialist garage between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi-tions such as when driving through water, during heavy rain showers or after the vehicle has been washed in an automatic vehicle wash, since the brake discs and brake pads may be moist or even have a coating of ice on them in winter. You should dry the brakes as soon as possible (by applying and releasing the brakes several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when driving on roads which have been treated with road salt if you have not used the brakes for some considerable time beforehand. The layer of salt on the brake discs and brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has been parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly high speed if you do not make much use of the braking system or if surface corro-sion is present ⇒.
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the brake pedal can be depressed further, it is possible that a brake circuit of the dual-circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically ⇒page 28, “Brake system ”.
WARNING
•Only apply the brakes for the purpose of drying and cleaning the brake discs if the traffic conditions permit this. Do not place any other road users in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking system could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking efficiency until approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increasing the pres-sure on the brake pedal. This guideline also applies to any new brake pads installed at a future date.
Caution
•Never allow the brakes to rub by applying slight pressure if you do not wish to brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
•Before negotiating a steep downhill section, please reduce your speed and shift down into the next lower gear (manual gearbox) or select a lower driving stage (automatic gearbox). This enables you to make full use of the braking power of the vehicle and reduces the strain on the brakes. Any additional braking should be done intermittently, not continuously.
Brake booster
The brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only generated when the engine is running.
NKO A05F 20.book Page 154 Wednesday, April 2, 2008 1:02 PM
Intelligent Technology155
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running. Greater physical effort for braking is required when engine is switched off. Because if you do not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)*
ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle. Compared to a car not fitted with the ABS brake system, you are able to retain optimal steering ability even during a full brake application on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all circumstances as a result of the ABS. The braking distance for example on gravel and fresh snow, when you should anyway be driving slowly and cautiously, will be longer.
Operating principle
As soon as the vehicle speed has increased to about 20 km/hour an automatic test procedure is conducted during which you will be able to hear a pumping noise for about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tending to lock. This control cycle is notice-able from a pulsating movement of the brake pedal which is accompanied by noises. This is consciously intended to provide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optimally control the brake application in this braking range. Never interrupt the application of the brakes!
WARNING
•The ABS can also not overcome the physical limits of your vehicle. Please do not forget this, particularly when driving on icy or wet road surfaces. If the ABS is operating within the control range, adapt your speed immediately to the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!
•The normal braking system is still fully functional if there is an ABS fault. Visit a specialist garage as quickly as possible and adjust your style of driving to take account of the ABS fault in the meantime since you will not know how great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system ⇒page 27.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-ment of tyres and wheels) can influence the function of the ABS ⇒page 200, “Accessories, changes and replacement of parts”.
Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but do not depress the brake pedal with sufficient pressure. Consequently, it is not possible for the car to achieve its maximum deceleration and the car covers a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure exists than during a normal brake applica-tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the car. You must apply the brake
NKO A05F 20.book Page 155 Wednesday, April 2, 2008 1:02 PM
Intelligent Technology156
pedal firmly and hold it in this position in order to achieve the shortest possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure required in the brake system. It fully exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available. Further information on the ESP ⇒page 151.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic situation.
•The increased safety offered by the Brake Assist must not tempt you to take a greater safety risk than otherwise.
Electrohydraulic power steering
The power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering is turned to full lock when the vehicle is stationary. Turning the steering to full lock in such a situation will be accompanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The only difference is that greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due to the low vehicle network voltage if the battery has gone flat and the engine must started with the help off jump leads. This condition will be indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific range when engine is running. It also operates again, if the engine can be started with its own battery.
Caution
Do not leave the steering at full lock for more than 15 seconds when the engine is running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if there is a leak or fault in the system.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference of the individual wheels. If the infla-tion pressure and therefore the rolling circumference of a wheel has changed signif-icantly, the warning light lights up in the dash panel ⇒page 26. The tyre inflation pressure-control system functions late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,

Intelligent Technology157
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•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 194.
•Switch on the ignition.
•Press button ⇒page 156, fig. 160 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 “adaptation” 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 one 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 194, “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 manoeuvres. 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 correct 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 inflation 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.

Diesel particle filter* (diesel engine)
In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 161 indicates that your
vehicle is equipped with a diesel particle filter. The vehicle data sticker is
located on the floor of the luggage compartment and is also stated in the
Service schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The soot is collected in the diesel particle filter and burnt regularly. To assist this proce-dure, we recommend not to drive regularly over short distances.
If the diesel particle filter is clogged or there is a fault, it is indicated by the warning light ⇒page 29, “Diesel particle filter* (diesel engine)”.
WARNING
•The diesel particle filter achieves very high temperatures. Therefore do not park at points where the hot filter comes into direct contact with dry grass or other combustible materials - risk of fire!
•Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalytic converters, heat shields or diesel particle filter. When the engine reaches its operating temperature, these substances might ignite - risk of fire!
Note
•When using diesel fuel with high sulphur content the life of the diesel particle filter is clearly reduced. A specialist garage will be able to tell you which countries use only diesel fuel with high sulphur content.

Catalytic converter
Proper operation of the emission control system (catalytic converter)
is of major significance for driving 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 177, “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 185, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒page 211, “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 catalytic 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, catalytic 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 leaded petrol will result in the catalytic converter being destroyed.
•If you detect misfiring, a drop in performance 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 into 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 conditions of the engine. This depends on the sulphur content of the fuel. It is often sufficient 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 environment and at the same time save money.

Towing a trailer166
Towing a trailer
To w i n g a t r a i l e r
Technical requirements
The towing device must satisfy certain technical requirements.
Your vehicle is designed primarily for transporting persons and luggage. It can, however, also be used for towing a trailer - provided certain technical equipment is fitted.
If your vehicle has been equipped with a towing device from Škoda Original Acces-sories, then the towing device satisfies all technical and legal requirements.
Your vehicle is fitted with a 13-pin power socket for the electrical connection between the vehicle and trailer. If the trailer which you wish to tow has a 7-pin connector, you can use a suitable adapter 6) from Škoda original accessories.
This work must be carried out in accordance with the manufacturer's specifications if a towing device is retrofitted.
Škoda Service Partners are familiar with details relating to retrofitting a towing device and for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original acces-sories installed by a Škoda Service Partner. He is familiar with all the relevant details relating to retrofitting such equipment. There is a risk of an accident if the towing device is not properly fitted!
General Maintenance
There are a number of points to pay attention to when towing a
trailer.
Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do not make full use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean sea level. The fact that the engine power output drops with increasing height due to a lowering of air pressure and thus the ability to climb, means that the trailer load must be reduced by 10% for every further increase of 1 000 metres in height above sea level. The towed weight is the weight of the (laden) vehicle and the (laden) trailer together. One should take this into account before driving up to higher alti-tudes.
The trailer and drawbar load information on the type plate of the towing device are merely test data for the towing device The data relating to your vehicle, which is often less than this test data, can be found in your vehicle registration documents or in the brochure - Technical Data.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for that of “fully laden”, ⇒page 194. The inflation pressure of the tyres fitted to the trailer adjust in accord-ance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors 6)In some countries the adapter is supplied with the towing device.
