Layout of this Owner's Manual (explanations)
6Layout of this Owner's Manual (explanations)The Owner's Manual has been systematically designed, in order to make it easy for you to find and absorb the information you require.Chapters, table of contents and subject indexThe text of the Owner's manual is divided into relatively short sections which are combined into easy-to-read
chapters
. The chapter you are reading at any particular
moment is highlighted at the bottom right of the page. The
Table of contents
is arranged according to the chapters and the detailed
Subject
index
at the end of the Owner's Manual helps
you to rapidly find the information you
are looking for.SectionsThe majority of
Sections
apply to all models.
Since there is a wide range of different equipment and options available it is clearly unavoidable, despite dividing the contents
into sections, that
mention may be made
of equipment whic
h is not fitted to your vehicle.
Brief information and instructionsEach section has a
Heading
.
This is followed by
Brief information
(in large italic lettering), which tells you the
subject which is dealt with in this section. Most of the illustrations are accompanied by an
Instruction
(in relatively large letters)
which explains to you in a straightforw
ard way the action you have to take.
Work steps

which have to be carried out are illustrated with a hyphen.Direction indicationsAll direction indications such as “left”, “right”,
“front”, “rear” relate to the direction of
travel of the vehicle.Explanation of symbols* Equipment which is marked in such a way is
only standard on certain vehicle model
versions or only suppliable as opti
onal equipment for certain models.
 End of a section.
 The section is continued on the next page.NotesAll four kinds of notes, which are used in th
e text, are always stated at the end of the
respective section.
WARNING
The most important notes are marked
with the heading WARNING. These
WARNING notes draw your attention to a serious risk of accident or injury. While reading the text you will frequent
ly encounter a double arrow followed
by a small warning symbol. This symbol is intended to draw your attention to a WARNING note at the end of the section to which you must pay careful atten- tion.
Caution
A Caution
note draws your attention to the possib
ility of damage to your vehicle (e.g.
damage to gearbox), or points ou
t general risks of an accident.
For the sake of the environment
An
Environmental
note draws your attention to environmental protection aspects.
This is where you will, for example, find tips
aimed at reducing your fuel consumption.
Note
A normal
Note
draws your attention in a general way to important information.

Technical Data
Single-trip memory (memory 1) The single-trip memory collates the driving information from the moment the ignition is switched on until it is switched off. New data will also flow into the calculation of the current driving information if the trip is continued
within 2 hours
after switching off
the ignition. The memory will be is automatically erased, on the other hand, if the trip is interrupted for
more than 2 hours
.
Total-trip memory (memory 2) The total distance driven memory gathers da
ta from any number of individual jour-
neys up to a total of 99 hours and 59 minutes driving or 9.999 kilometres driven. The memory is deleted when either of these limits is reached and the calculation starts from anew. The total-trip memory will not, contrary to

the roof of your vehicle:•
A special roof luggage rack system was de
veloped for the vehicle, that is why you
should only use a roof luggage rack which has been released for use by Škoda Auto.•
The roof rail is the basis for a complete
roof luggage rack system. Separate addi-
tional holders are required for safety reasons for transporting luggage, bikes, surf-boards, skis and boats.•
The basic version of the roof luggage rack system and further components are
obtainable as accessories from the specialist garages.
Caution
•
Ensure that the opened boot lid do
es not collide with the roof load.
•
On models fitted with a power sliding/tilting roof, ensure that the opened
sliding/tilting roof does not strike any items of luggage transported on the roof.
For the sake of the environment
The increased aerodynamic drag resu
lts in a higher fuel consumption.
Roof loadDistribute weight evenly over the roof lu
ggage rack system. The maximum permissible
roof load (including roof rack system) of
75 kg
and the maximum
permissible total
weight of the vehicle should not be exceeded. You cannot make full use of th
e permissible roof load if
you use a roof luggage rack
system with a lower load carr
ying capacity. The load transported on the roof luggage
rack system must not exceed the weight limit
which is stated in the fitting instructions.
WARNING
•
The items which you transport on the roof bar system must be reliably
attached - risk of accident!•
You must on no account exceed the pe
rmissible roof load, the permissible
axle loads and the permissible gross weight of your vehicle - risk of accident!

Technical Data
Recirculated air mode In recirculated air mode air is sucked out of the interior of the vehicle and then fed back into the interior.Recirculated air mode prevents polluted air
outside the vehicle from getting into the
vehicle, for example when driving through a
tunnel or when standi
ng in a traffic jam.
Switching recirculated air mode on– Press the button
⇒page 99, fig. 109
the warning light lights up in the
button.
Switching recirculated air mode off– Press again the button - the warning light in the button goes out. The recirculated air mode is switched off automatically if the air distribution control is in position
 ⇒page 99, fig. 109
. You can also switch recirculated air mode on
again from this setting by re
peatedly pressing button .
WARNING
You should not leave recirculated air mode on over a longer period of time, as “stale” air may result in fatigue in the driver and occupants, divert your atten- tion and also cause the windows to mist up. The risk of having an accident increases. Switch recirculated air mode off as soon as the windows begin misting up.Using the air conditioning system economicallyThe compressor on the air conditioning syst
em uses power from the engine when in
cooling mode which will effect the fuel consumption. It recommended to open the windows or the
doors of a vehicle for which the interior
has been strongly heated through the effect
of direct sunlight in order to allow the
heated air to escape. The cooling system should not be switched
on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.
Operational problemsIf the cooling system does not operate at outside temperatures higher than +5 °C, there is a problem in the system. The reasons for this may be:•
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary
⇒page 233.
•
The cooling system has switched off auto
matically for a short time because the
coolant temperature of the engine is too hot
⇒page 17.
If you are not able to rectify the operational
problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage.Climatronic* (automatic air conditioning)Description The Climatronic system is a combination of an automatic heating, fresh air and cooling system which provides optimal comfort for the occu-pants of the car.The Climatronic maintains fully automatically a convenience temperature. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which elim- inates the need to alter the settings manually. The
automatic mode

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 200,
“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 206, “Replenishing engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒page 230,
“Tow-starting and towing 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 ve
hicle 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 converte
r, 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 cata
lytic converter.
•
Filling the tank even only once with lead
ed 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 en
gine. This de
pends 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 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, 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 econom-
ical 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 cond
itions such as poor road conditions, towing a trailer,
etc.
