mitted to the road surface is automatically adapted by reducing the engine
speed. This occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 189, “Antilock
brake system (ABS)”. The TCS will not function if a fault exists in the ABS
system.
The TCS warning light ⇒page 35 lights up in the instrument cluster when
there is a fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the
button ⇒page 186, fig. 165 . The TCS warning light ⇒page 35 lights up
in the instrument cluster when the TCS is switched off.
The TCS should normally always be switched on. It may be good practice
to switch the system off only in particular exceptional situations if you
desire wheel slip.
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.
The EDL ⇒page 187, “Electronic Differential Lock (EDL)” is a part of the
TCS. THE EDL operates independently of the TCS (also when the TCS
has been switched off using the TCS button).
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
assignment of tyres and wheels) can influence the function of the TCS
⇒ page 242, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)
The electronic differential lock prevents an individual
wheel from slipping.
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 slippery 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 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
assignment of tyres and wheels) can influence the function of the EDL
⇒ page 242, “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 necessary 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 conditions 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 avail-
able 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 corrosion 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 36,
“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 fric-
tion force. You can, 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.
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, 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.
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 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 35.
•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 242, “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.

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.

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.

Driving and the Environment
196
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. 167 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.

Motoring abroad
General
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 a.s. 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.
Headlight
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. Headlight stickers can be obtained as a spare part from the Skoda Service
Partners.
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 Service
Partner.
Note
You can obtain further information regarding masking over or converting
the headlights from your Škoda Service Partner.
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.
