soon as possible by applying and releasing the brakes several times.
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated wi th road salt if you have not used the
brake s for s ome cons ide ra bl e time be foreha nd . T he la yer of s alt on the brake di scs a nd
brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period an d if you do not make much use of the braking system.
We recommend cleaning the brak e 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 corrosion is
present .
Faults in the brake surface
If you notice that the braking distance ha s 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 31, “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 jeop-
ardy.

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 other-
wise the braking system could run too hot.

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 br
aking force by increasing the pressure
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, reduce your speed, shift down into the
next lower gear. 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 intermit-
tently, not continuously.
Brake boosterThe brake booster boosts the pressure whic h you generate with the brake pedal. The
necessary pressure is only genera ted when the engine is running.
WARNING

Never switch off the engine befo re the vehicle is stationary.

The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine 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 significan tly to enhancing the active safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a full br ake application on a slippery road surface
because the wheels do not lock up.

Technical Data
You must not expect, however, that the br
aking 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
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 poss ible and adjust your style of driving to
take account of the ABS fault in the meantime since you will not know the
extent of the fault and in how far the braking efficiency is affected.Note

A warning light comes on if a fault occurs in the ABS system page 30.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the ABS page 166, “Accesso-
ries, 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 a pply the brakes in good time in dangerous situations, but
do not depress the brake pedal with suffi cient pressure. Consequently, it is not
possible for the vehicle to achieve its maximum deceleration and the vehicle covers a
greater distance than necessary.
The Brake Assist is activated by the very qu ick 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 dece leration of the vehicle. You must apply the brake pedal
firmly and hold it in this position in or der to achieve the shortest possible braking
distance.
The Brake Assist is able to help you achi eve 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
vehicle 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.

Driving and the EnvironmentThe first 1 500 kilometres and then afterwardsA new engine
The engine has to be run in du ring the first 1 500 kilometres.Up to 1 000 kilometres– Do not drive faster than 3/4 of the maximum speed of the gear in use, that is 3/4 of
the maximum permissi ble 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 maxi mum permissible engine revolutions.
During the first operating hours the engine ha s higher internal friction than later until
all of the moving parts have harmonized. Th e driving style which you adopt during the
first approx.1 500 kilometres plays a decisive part in the success of running in your
vehicle.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is complete . The maximum permissible en gine speed is marked by
the beginning of the red zone on the scale of the revolutions counter. Shift up into the
next higher gear on a vehi cle 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 unnecessari ly high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fu el consumption and operating noise levels
and protects the environment.New tyresNew 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 padsAllow for the fact that new brake pads do no t 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 ca n, however, compensate for this slightly
reduced braking force by increasing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in pe riod, you should avoid excessive stresses on the brakes. This
includes, for example, violent braking, part icularly from very high speeds, and also
when crossing mountain passes.

Catalytic converterProper operation of the emission cont rol 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 144.
– 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 151, “Replenishing engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres page 175,
“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 la ter when driving the vehicle into a country
in which use of a catalyti c 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

On vehicles fitted with a catalytic converter, never let the fuel tank run completely
empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel
may get into the exhaust system an d 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 misfir ing, 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 ma y 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 pr operly, a sulphur-like exhaust odour may be
produced under certain oper ating conditions 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 mannerGeneral
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, depe nd 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 econom-
ical way with foresight. This section is in tended 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 cond itions 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 nega tive 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.
The optimal engine speed should be obtained when accelerating, in order to avoid a
high fuel consumption and resonance of the vehicle.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.
An effective way of achieving good fuel economy is to shift up early. You will consume
more fuel if you drive at unnecessaril y high revolutions in any given gear. The
fig. 136 shows the ratio of fuel consumption to the speed of your vehicle in the
relevant gears. Fuel consumptio n in 1st gear is the highest and in 5th gear is the lowest.
Note
Also use the information supplied by the multi-functional indicator* page 19.Avoiding full throttle
Driving more slowly means saving fuel.Sensitive use of the accelerator will not only significantly reduce fuel consumption but
also positively influence environmenta l pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The fig. 137 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 th an 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 an d 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 revolu tions 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 on ly 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 consider-
able extent on the load and speed of the en gine. 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 has 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 consum ption 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 vehicle at regu lar 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 emissions.
The cold engine vehicle cons umes 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 stabi-
lizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
 fig. 138 shows the different fuel consumptions for the same distance, on the one
hand at +20°C and on the ot her 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 t oo low. This will not
only increase fuel consumption but also tyre wear and the driving behaviour will
worsen.
Always check the inflation pr essure 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 consumption means
that it is worth taking a look in the lu ggage 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 kilogr ams will cause an increase in fuel consump-
tion 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 increased aerodyna mic drag of your vehicle causes it to use
about 10% more fuel than normal at a sp eed 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 electrical components switched on, the more fuel
will be consumed for operating the
alternator.
Keeping a log of your fuel consumptionIf 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 (p ositive 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 compatibilityEnvironmental 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:

Motoring abroadGeneral
Other circumstances may exist abroad.It is also possible, in certain 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 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 mainte-
nance work and possibilities for getting repairs done.Unleaded petrolA vehicle fitted with a petrol engine must always be refuelled with unleaded petrol
 page 129. The automobile as sociations can provide you with information regarding
the locations of filling stations which offer unleaded petrol.HeadlightThe low beam of your headlights is set asymmetrically. It illuminates the side of the
road on which you are driving to a greater ex tent. If you drive abroad on the other side
of the road, you will dazzle oncoming traffic.
In order to prevent the dazzling of oncoming traffic, it is necessary to stick a sticker over
a certain part of the headlights. Headlight stickers can be obtained as a
spare part from the specialist garages.
The adaptation of the headlights with Xe non lamps (applies to vehicles which are
designed for driving on the left and on the ri ght) is performed by switching over a bezel
in the module for low beam by a specialist garage.
Note
You can obtain further information regardin g masking over or converting the head-
lights from your specialist garage.Avoiding damage to your vehicleWhen 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.
