Operating principle
As soon as the vehicle speed has increased to about 6 km/hour an auto-
matic 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 noticeable 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 ta ke 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 36.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other
assignment of tyres and wheels) can influence the function of the ABS
⇒ page 243, “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 situ-
ations, but do not depress the brake pedal with sufficient pressure. Conse-
quently, 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 application. 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 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.
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.

Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
The steering characteristics can be changed by a specialist garage.
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.
If the steering is turned to full lock when the car is stationary, you will
place great stresses on the power steering system. Turning the steering
to full lock in such a situation will be accompanied by noises. In addition,
the idling speed of the engine will drop briefly.
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.
•The power steering requires a special hydraulic oil. The oil reservoir is
located at the front left of the engine compartment ⇒page 220. The
correct hydraulic oil level is important for proper operation of the power
steering system.

Driving and the Environment
The first 1 500 kilometres and then
afterwards
A new engine
The engine has to be run in during the first 1 500 kilome-
tres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear
in use, that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the
full speed of the gear engaged, that is up to the maximum
permissible engine revolutions.
During the first operating hours the engine has higher internal friction than
later until all of the moving parts have harmonized. The driving style which
you adopt during the first 1 500 kilometres plays a decisive part in the
success of running in your car.
You should not drive at unnecessarily high engine revolutions even
after the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revo-
lutions counter. Shift up into the next higher gear on a vehicle fitted with
manual gearbox before the red zone is reached.
Extremely high engine
revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also
applies: Do not drive at engine revolutions which are too low. Shift down
as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is
at its normal operating temperature. Never rev up an engine which is cold,
neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a
higher gear as early as possible are ways to minimise fuel consumption
and operating noise levels and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
You should take account of this fact for the first 500 kilometres and drive
particularly carefully.

New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency 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.
During the running-in period, you should avoid excessive stresses on the
brakes. This includes, for example, violent braking, particularly from very
high speeds, and also when crossing mountain passes.
Catalytic converter
Proper operation of the emission control system (catalytic
converter) is of major significance for driving your vehicle
in an environmentally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒page 214, “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 223,
“Replenishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 258, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not avail-
able, 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-protec-
tion 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 cata-
lytic 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.

Driving and the Environment
194
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.
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 vehicle at the works. Special
attention has been given to minimising negative effects on the environ-
ment. 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 braking unnecessarily. If you drive with forsight
you will not need to brake so often and will also then not have to accel-
erate 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 unnecessarily high revolutions in
any given gear. The
⇒fig. 162 shows the ratio of fuel consumption to the speed of your
vehicle for the individual gears. Fuel consumption in 1st gear is the
highest, while that in 5th or the 6th gear is the lowest.
Only depress the accelerator pedal slowly if your vehicle is fitted with an
automatic gearbox in order to automatically select an economic driving
programme. You will achieve good fuel economy by shifting up early and
shifting down late. This applies in particular if you make use of the manual
mode (Tiptronic) for shifting gears.
Note
Also use the information supplied by the multi-functional indicator
⇒ page 18.
Avoiding full throttle
Driving more slowly means saving fuel.

Driving and the Environment

Sensitive use of the accelerator will not only significantly reduce fuel
consumption but also positively influence environmental pollution and
wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever
possible. Fuel consumption, pollutant emissions and vehicle noises
increase disproportionally at high speeds.
The ⇒page 195, fig. 163 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-quarters 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 lengthy 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 emissions, 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 serviced 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 fuel 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 considerable extent on the load and speed of the engine. Oil consump-
tion 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 has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption 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 regular 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 must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine vehicle consumes approx. 20 - 30 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 15 litres/100 km
after just 1 kilometre. The engine reaches its operating temperature
(outside temperature and engine dependent) only after about 4 to 10 kilo-
metres 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 ⇒fig. 164 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 consumption 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 ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consump-
tion means that it is worth taking a look in the luggage compartment to
avoid transporting any unnecessary ballast.
It is particularly in town traffic, when 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 conven-
ience, although you no longer need it. The increased 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 elec-
trical power. The greater the load on the alternator as a result of having a
large number of electrical 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 exercise. 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 you have driven the vehicle since you
last refuelled.
Environmental compatibility
Environmental protection has played a major role in the design, selection
of materials 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 Recommen-
dation 260
•Reduced fuel consumption and exhaust emission CO2
•Minimum fuel leakage during accidents
•Reduced noise
Choice of materials
•Extensive use of recyclable material
•Air conditioning filled with CFC-free refrigerant
•No cadmium
•No asbestos
•Reduction in the “vaporisation” of plastics
Manufacture
•Solvent-free cavity protectionolvent-free protection of the vehicle for
transportation from the production plant to the customer
•The use of solvent-free adhesives
•No CFCs used in the production process
•without use of mercury
•Use of water-soluble paints

Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in certain countries, that the Škoda dealership network
has not been established yet. This is the reason why obtaining certain
spare parts may be somewhat complicated and specialist garage
personnel may only be able to make limited repairs. Škoda Auto in the
Czech Republic and relevant importers are happy to provide information
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 193. 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 asymmetrically. 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 will dazzle oncoming traffic.
It is necessary in order to avoid dazzling oncoming traffic to stick a sticker
over a certain part of the headlights.
Windscreen wiper stickers are available at Škoda dealers. Headlights with Xenon lamps are designed for driving in countries with
traffic on the right or on the left. Have this done always at a Škoda dealer.
Note
You can obtain further information regarding masking over or converting
the headlights from your Škoda dealer.
Avoiding damage to your vehicle
When driving on poor roads and lanes or when driving over kerbstones,
steep ramps etc., you must pay particular attention to ensuring that any
low-slung parts of the vehicle, such as spoiler and exhaust, do not touch
the ground and get damaged.
This particularly applies to models with a lowered suspension (sport
suspension) and also when your vehicle is fully laden.
