Driving safety
Read and observe
on page 8 first.
The driver is fully responsible for himself and his occupants. If your driving
safety is affected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. Do not become distracted from concentrating on the traffic situation, e.g.
by your passengers or mobile phone calls.
Never drive when your driving ability is impaired, e.g. due to medication, al-
cohol or drugs.
Keep to the traffic regulations and the permissible speed limit.
Always adjust the driving speed to the road, traffic and weather condi-
tions.
Take regular breaks on long journeys – at least every two hours.

The warning lights indicate certain functions or faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test.
If the tested systems are OK, the corresponding warning lights go out a few
seconds after switching on the ignition or after starting the engine.

If the warning light
illuminates , there is a fault in the airbag system.
The following message is shown in the MAXI DOT display. Fault: Airbag
The operational capability of the airbag system is monitored electronically,
even if one of the airbags is switched off.
If a front, side or head airbag or belt tensioner has been switched off using
the vehicle system tester:
› The warning light
illuminates for approximately 4 seconds after the igni-
tion is switched on and then flashes again for approximately 12 seconds.
The following message is shown in the MAXI DOT display. Airbag/belt tensioner deactivated.
If the front passenger's front airbag was switched off using the key-operat-
ed switch on the side of the dash panel on the passenger side:
› The warning light
illuminates for approximately 4 seconds after the igni-
tion is switched on;
› The deactivated air bag is indicated by the illumination of the warning light

» page 21.
WARNINGWhen a fault in the airbag system occurs, there is a risk of the system not
being triggered in the event of an accident. Therefore, this must be
checked immediately by a specialized company.
Tyre inflation pressure
Read and observe
on page 35 first.
The warning light is illuminated
If while driving, the warning light illuminates, a tyre pressure change has oc-
curred.
An audible signal sounds as a warning signal.
›
Immediately reduce speed and avoid sudden steering and braking manoeu-
vres.
› Stop the vehicle, turn the ignition off and check the tyres and their inflation
pressure » page 198 .›
Correct the tyre pressure, if necessary or replace the wheel » page 205 or
use the repair kit » page 209.
›
Store the tyre pressure values in the system » page 166.
The warning light
flashes for about 1 min. and remains lit
If the warning light
flashes for approximately 1 minute and stays on, there
may be a fault in the tyre pressure monitoring system.
›
Stop the vehicle, turn the ignition off and start the engine again.
If the warning light
flashes again after the engine has started, there is a
system error.
Seek help from a specialist garage.
The following reasons can explain the warning light being illuminated.
› The vehicle is loaded on one side. Distribute loads as evenly as possible.
› The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
› Snow chains are mounted.
› A wheel has been changed.
Store the tyre pressure values in the system » page 166.
CAUTION
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light in the instrument cluster can be delayed or does
not light up at all.
Note
The warning light illuminates after the ignition is switched on if the vehi-
cle's battery has been disconnected and reconnected. If the warning light does
not go out after moving a short distance, this means that there is an error in
the system. Seek help from a specialist garage.
Windscreen washer fluid level
Read and observe
on page 35 first.
If the windscreen washer fluid level is too low, the warning light

›Place heavy objects as far forward as possible.›Attach the items of luggage to the lashing eyes or using the
nets » page 99 .
In the event of an accident, even small and light objects gain so much kinetic
energy that they can cause severe injuries.
The magnitude of the kinetic energy is dependent on the speed at which the
vehicle is travelling and the weight of the object.
Example: In the event of a frontal collision at a speed of 50 km/h, an object
weighing 4.5 kg produces energy corresponding to 20 times its own weight.
This means that it results in a weight of approx. 90 kg “ ”.
Luggage compartment light
The light switches on/off when the luggage compartment lid is opened or
closed.
If the boot lid is open and the ignition switched off, the light will extinguish
automatically after around 10 minutes.
Boot light for Superb Combi vehicles » page 103.WARNING■
Always store transported objects in the boot and attach them to the lash-
ing eyes.■
Loose objects can be thrown forward during a sudden manoeuvre or in
case of an accident and can injure the occupants or other road users.
■
Loose objects could hit a deployed airbag and injure occupants – there is
a risk of death.
■
Please note that transporting heavy objects alters the handling proper-
ties of the vehicle due to the displacement of the centre of gravity – risk of
accident! The speed and style of driving must be adjusted accordingly.
■
If the items of luggage or objects are attached to the lashing eyes with
unsuitable or damaged lashing straps, injuries can occur in the event of
braking manoeuvres or accidents. To prevent items of luggage from moving
around, always use suitable lashing straps that are firmly attached to the
lashing eyes.
■
The transported items must be stowed in such a way that no objects are
able to slip forward on sudden driving or braking manoeuvres – risk of in-
jury!
WARNING (Continued)■ When transporting objects in the luggage compartment that has been en-
larged by folding the rear seats forward, ensure the safety of the passen-
gers transported on the other rear seats » page 11.■
If the rear seat next to the folded forward seat is occupied, ensure maxi-
mum safety, e.g. by placing the goods to be transported in such a way that
the seat is prevented from folding back in case of a rear collision.
■
Do not drive with the luggage compartment lid open or unlatched, other-
wise exhaust gases may get into the interior of the vehicle – risk of poison-
ing!
■
Do not exceed the permissible axle loads and permissible gross weight of
the vehicle – risk of accident!
■
Do not transport people in the boot!
CAUTION
■ It is important to ensure that the heating elements of the rear window heat-
er, the threads of the integrated antenna in the rear window as well as the
threads of the integrated antenna (Superb Combi) in the rear side windows,
are not damaged by abrasive items.■
Tyre pressure must be adjusted to the load » page 198.
Class N1 vehicles
Read and observe
and on page 98 first.
On class N1 vehicles, which are not fitted with a protective grille, a lashing set
which complies with the standard EN 12195 (1 - 4) must be used for fastening
the load.
The proper functioning of the electrical system is essential for the safe opera-
tion of the vehicle. It is important to ensure that it is not damaged during mod-
ifications or when loading or unloading the luggage compartment.

New tyres
New tyres must firstly be “run in” since they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads do not initially provide optimal braking performance. They first
need to be “run in”. Therefore, drive especially carefully for the first 200 km or
so.

The technical requirements for low fuel usage and economic efficiency of the
vehicle have already been built into the vehicle at the works. ŠKODA places a
particular emphasis on minimising negative 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.
Fuel consumption, environmental pollution and the wear to the engine, brakes
and tyres depend essentially on the following three factors:
› Your personal driving style
› Operating conditions
› Technical requirements
The fuel economy by can be improved by 10 - 15 % by always looking ahead
and driving in an economical way.
Fuel consumption is also be influenced by external factors which are beyond
the driver's control. Consumption increases during the winter or under difficult
conditions, on poor roads, etc.
Fuel consumption can vary considerably from the manufacturer's data, as a re-
sult of outside temperatures, the weather and driving style.
The optimal engine speed should be maintained when accelerating, to avoid a high fuel consumption and resonance of the vehicle.
CAUTION
All the speed and engine revolution figures apply only when the engine is at
its normal operating temperature.
Looking ahead
Read and observe
on page 149 first.
A vehicle's highest fuel consumption occurs when accelerating, therefore un-necessary accelerating and braking should be avoided. If looking ahead when
driving, less braking and consequently less accelerating are required.
If possible, let your vehicle coast to a stop, or use the engine brake, if you can see that the next set of traffic lights is on red, for example.
Economical gear changing.
Fig. 142
Principle sketch: Fuel consump-
tion in litres/100 km depending
on the selected gear
Read and observe on page 149 first.
Shifting up early saves on fuel.
Manual gearbox › Drive no more than about one length of your vehicle in first gear.
› Shift up into the next gear at approximately 2,000 rpm.
149Starting off and Driving
Page 153 of 252
An effective way of achieving good fuel economy is to shift up early. Observe
the recommended gear » page 43, Gear recommendation .
A suitably selected gear can have an effect on fuel consumption » Fig. 142.
Automatic gearbox
› Slowly
apply the accelerator pedal. However, do not depress it as far as the
kickdown position » page 147.
› An economic driving programme is automatically selected if the accelerator
pedal is only depressed slowly.
Avoiding full throttle
Fig. 143
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h.
Read and observe on page 149 first.
Driving more slowly saves fuel.
Sensitive use of the accelerator will not only significantly reduce fuel con-
sumption but also positively influence environmental pollution and wear of
your vehicle.
The maximum speed of your vehicle should, as far possible, never be used.
Fuel consumption, pollutant emissions and vehicle noises increase dispropor-
tionally at high speeds.
The graph » Fig. 143 shows the ratio of fuel consumption to the speed of your
vehicle. Fuel consumption will be halved if you drive at only three-quarters of
the possible top speed of your vehicle.
Reducing idling
Read and observe
on page 149 first.
Idling also costs fuel.
In vehicles not equipped with the START STOP system, turn off the engine
when in a traffic jam, at a level crossing or traffic lights with longer wait times.
Even after just 30 - 40 seconds you will have saved more fuel than that is nee-
ded when you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal operat-
ing temperature. Wear-and-tear and pollutant emissions, though, are particu- larly high in the warming-up phase. Therefore, start driving as soon as the en-
gine has started, In this case high engine speeds should be avoided.
Avoiding short distances
Fig. 144
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Read and observe on page 149 first.
Short distances result in above-average high fuel consumption. We therefore
recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel con- sumption drops to 10 litres/100 km after just 1 kilometre. The consumption sta-
bilises once the engine and catalytic converter have reached their operating
temperature.
An important factor in this connection is also the ambient temperature. The
graph » Fig. 144 shows the different levels of fuel consumption after driving a
certain distance at a temperature of +20 °C and a temperature of -10 °C.
Checking tyre pressure
Read and observe
on page 149 first.
Tyres which are correctly inflated save fuel.
150Driving
Page 154 of 252
Always ensure the tyre inflation pressure is correct » page 198. If the pressure
is too low, the tyres will have to overcome a higher rolling resistance. This will
not only increase fuel consumption but also tyre wear and the driving behav-
iour will worsen.
Always check the tyre inflation pressure when the tyres are cold.
Avoiding unnecessary ballast
Read and observe
on page 149 first.
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. Therefore we rec-
ommend carrying no unnecessary weight.
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 in-
crease in fuel consumption of about 1 litre/100 kilometres.
At a speed of 100 - 120 km/h, a vehicle fitted with a roof rack cross member
without a load will use about 10 % more fuel than normal due to the increased
aerodynamic drag.
Regular maintenance
Read and observe
on page 149 first.
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a specialist garage, you create
the conditions needed for economical driving. The maintenance state of your
vehicle has a positive effect on traffic safety and value retention
A poorly tuned engine can result in a fuel consumption which is 10 % higher than normal.
Check the oil level at regular intervals, e.g. when filling up. Oil consumption is
dependent to a considerable extent on the load and speed of the engine. 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 higher oil consumption at first, and
reaches its lowest level only after a certain running in time. The oil consump-
tion of a new vehicle can therefore only be correctly assessed after driving
about 5,000 km.
For the sake of the environment■ Additional improvements to the fuel economy can be made by using synthet-
ic low viscosity oils.■
Regularly check the ground under the vehicle. Have your vehicle inspected by
a specialist garage if you find any stains caused by oil or other fluids on the
ground.
Note
We recommend that your vehicle be serviced on a regular basis by a ŠKODA
service partner.
Saving electrical energy
Read and observe
on page 149 first.
When the engine is running, the alternator generates and supplies electricalpower. If more electrical components of the electrical system are switched on,
more fuel is needed to operate the alternator. We therefore recommend
switching off electrical components if these are no longer required.
Environmental compatibility
Read and observe
on page 149 first.
Environmental protection has played a major role in the design, material selec-
tion and production of your new ŠKODA. Particular emphasis has been placed
on the following points.
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 Recommendation
260.
› Reduced fuel consumption and exhaust emission CO
2.
› Minimum fuel leakage during accidents.
› Reduced noise.
Choice of materials
› Extensive use of recyclable material.
› Air conditioning filled with CFC-free refrigerant.
› No cadmium.

Fatigue detection (break recommendation)
Introduction
This chapter contains information on the following subjects:
Function
165
Information messages
165WARNING■ For the driving ability is always the driver's responsibility. Never drive if
you feel tired.■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The fatigue detection system is designed primarily for motorway driving.
Function
Read and observe
on page 165 first.
The fatigue detection system advises the driver on the basis of information
about the steering behaviour, to take a break from driving. The system recom-
mends a break at speeds of 65-200 km/h.
After the ignition has been switched on, the system evaluates the steering be-
haviour for 15 minutes. This baseline analysis is constantly compared with the
current steering behaviour.
If the system detects deviations from normal steering behaviour due to possi-
ble fatigue of the driver, it recommends taking a break from driving.
The system deletes the stored baseline analysis if one of the following con-
ditions is met.
› The vehicle is stopped and the ignition switched off.
› The vehicle is stopped, the seat belt removed and the driver's door opened.
› The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the As-
sistants menu option » page 47.
Information messages
Read and observe
on page 165 first.
In MAXI DOT display the icon appears for a few seconds and the following
message.
Fatigue detected. Take a break!
An audible signal is also emitted.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
166
The tyre pressure monitoring function (hereinafter referred to only as a sys-
tem) monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light in the
instrument cluster illuminates and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 40 .
The system can only function properly if the tyres have the prescribed inflation
pressure and this pressure values are stored in the system.
WARNING■ Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 198.■
The system cannot warn in case of very rapid loss of tyre pressure, e.g. in
the event of a sudden puncture.
