15Instruments and warning lights

›Average speed
› Driving time
Since start
The 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. If the trip is interrupted for more than 2 hours, the
memory is automatically erased.
Long-term
The memory gathers driving information from any number of individual journeys
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 all over again.
Since refuel
The memory gathers driving information since the last refuelling. The memory is erased automatically the next time you fill up.
Note
Disconnecting the vehicle battery will delete all memory data.
Multifunction display details
First read and observe the introductory information and safety warn-
ings
on page 22.
Range
The range indicates the distance you can still drive with your vehicle based on the
level of fuel in the tank and the same style of driving as before.
The display is shown in steps of 10 km. After lighting up of the indicator light 
the display is shown in steps of 5 km.
The fuel consumption over the last 50 km is used to calculate the range. Therange can increase if you drive in a more fuel-efficient manner.
Average fuel consumption
The average fuel consumption 1)
is calculated since the last time the memory was
erased » page 22 .
If you wish to determine the average fuel consumption over a certain period of
time, you must set the memory at the start of the new measurement to zero » Fig. 3 on page 22. After erasing the memory, no fuel consumption data will
appear for the first 100 m driven.
The fuel consumption data is updated regularly while you are driving.
Current fuel consumption
You can use this information to adapt your driving style to the desired fuel con-
sumption 1)
.
The display appears in litres/hour if the vehicle is stationary or driving at a low
speed 2)
.
Oil temperature
If the engine oil temperature is in the range 80-110 °C, the engine operating tem-
perature is reached.
If the temperature lies below 80 °C or above 110 °C, avoid high engine revs, full
throttle and high engine loads.
If the oil temperature is lower than 50 °C or if a fault in the system for checking
the oil temperature is present, 
are displayed instead of the oil temperature.

23Information system

Driving and the Environment
Running in
New engine
The engine has to be run in during 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, i.e. 3/4 of
the maximum permissible engine speed.
›
No full throttle.
›
Avoid high engine speeds.
›
Do not tow a trailer.
From 1 000 up to 1 500 kilometres
Gradually increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
During the first operating hours the engine has higher internal friction than lateruntil all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1 500 kilometres plays a decisive part in the success of running in your car.
Never drive at unnecessarily high engine speeds even after the running-in period
is complete. The maximum permissible engine speed is marked by the start of the red scale area of the revolutions counter.
On vehicles fitted with a manual gearbox, at the very latest shift up into the nextgear when the red area is reached. Very high engine speeds when accelerating
(accelerator) are automatically restricted »
.
If the engine is no longer running smoothly, do not drive with unnecessarily low
engine revs on a vehicle with manual transmission. Shift down. Observe the rec-
ommended gear » page 21.
CAUTION■
The engine is not protected from excessive engine revs caused by shifting
down at the wrong time. This can result in the sudden increase in revs beyond
the permissible maximum rpm and thus cause engine damage.■
Never rev up a cold engine when the vehicle is stationary or when driving in in-
dividual gears.
■
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature.
For the sake of the environment
Never drive with unnecessarily high engine revs. Shifting up sooner helps save on
fuel, reduces engine noises and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so.

New brake pads
New brake pads initially do not provide optimal braking performance. They first need to be “run in”. Drive especially carefully for the first 200 km or so.

Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
› Vehicles fitted with a petrol engine must always be refuelled with unleaded
petrol » page 168 .
› Do not pour too much oil into the engine
» page 172, Checking the engine oil
level .
› Do not switch off the ignition while you are driving the vehicle.
If you drive your vehicle in a country in which unleaded petrol is not available, you must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. 
100Using the system

Information about convenience consumers and the amount of fuel con-sumed » operating instructions for Infotainment , chapter Setting vehicle systems
(CAR button) .
A maximum of three convenience consumers are displayed in the Infotainment
display- the top 3 in terms of energy consumption.
You can decide to switch off the consumers or to set them to a lower level to re-duce the level of fuel consumption.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. If the inflation pressure is too
low, the tyres must overcome a higher rolling resistance. This will not only in-
crease fuel consumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold.

Avoid unnecessary ballast
Transporting ballast costs fuel.
Every additional kilogram in weight increases the fuel consumption. We there-
fore recommend you do not travel with any unnecessary weight.
It is particularly in town traffic, when one is accelerating quite often, that the ve-
hicle 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.
At a speed of 100 - 120 km/h, a vehicle fitted with a roof rack cross member with-
out a load will use about 10 % more fuel than normal due to the increased aero- dynamic drag.

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a ŠKODA specialist garage, you
create the conditions needed for driving economically. 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 at regular intervals, e.g. when filling up. Oil consumption is depend-
ent 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 rea- ches its lowest level only after a certain running in time. The oil consumption of anew vehicle can therefore only be correctly assessed after driving about5 000 km.
For the sake of the environment
■ Additional improvements to the fuel economy can be made by using synthetic
high-lubricity oils.■
Regularly check the ground under the vehicle. Have your vehicle inspected by a
ŠKODA specialist garage if you find any stains caused by oil or other fluids on the
floor.
Note
We recommend that your vehicle is serviced on a regular basis by a ŠKODA Part-
ner.
Environmental compatibility
Environmental protection has played a major role in the design, selection of mate-
rials and manufacture 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.

103Driving and the Environment

■Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.■
In no case may fuel additives with metal components be used, especially not
with manganese and iron content. Do not use any LRP fuels (lead replacement petrol) with metal parts - risk of serious damage to parts of the engine or exhaust
system!
■
Do not use any fuels with metal parts - risk of serious damage to parts of the
engine or exhaust system!
■
The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 167.
Your vehicle can only be operated with diesel fuel, which complies with the
standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia).
All diesel engines can be operated with diesel fuel with a maximum content of
7 % bio-fuel (B7), which complies with the standard DIN 52638 in Germany (in
Austria C 1590, in France EN 590).
Operation in winter – Winter-grade diesel fuel In the cold season, only use “winter-grade diesel fuel” which will still operateproperly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel fuels available have a different temperature characteristic. The ŠKODA Partners and
filling stations in the relevant country will be able to provide you with information
regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25 °C.
Fuel additives
Fuel additives, so-called “flow improvers” (petrol and similar products) must not
be added to the diesel fuel.
CAUTION■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!■
Damage caused by using diesel fuel which does not comply with the standards
are excluded from the warranty.
■
If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that the
fuel system is cleaned by a ŠKODA Partner.
■
Water which has collected in the fuel filter can cause engine faults.
■
Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. The use of biofuel (RME) can cause considerable damage
to parts of the engine or fuel system.
■
Comply with the proscribed oil change intervals.

The engine consumes a little oil. The oil consumption may be as much as 0.5 l/ 1 000 km depending on your style of driving and the conditions under which you
operate your vehicle. Consumption may be slightly higher than this during the
first 5 000 kilometres.
The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey. 
172General Maintenance

Brake fluid changeFirst read and observe the introductory information and safety warn-
ings
on page 169.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment.
Excessive water in the brake fluid may be the cause of corrosion in the brake sys-
tem.
The water content lowers the boiling point of the brake fluid.
The brake fluid must comply with the following standards or specifications: › VW 50114;
› FMVSS 116 DOT4.
WARNINGDo not use used brake fluid - the function of the brake system may be im-
paired - risk of accident!
CAUTION
Brake fluid damages the paintwork of the vehicle.
Note
The brake fluid is replaced as part of a proscribed Inspection service carried out by
a ŠKODA Partner.
Windscreen washer system
Fig. 152
Engine compartment: Wind-
screen washer fluid reservoirFirst read and observe the introductory information and safety warn-
ings on page 169.
The windscreen washer fluid reservoir is located in the engine compartment and
contains the cleaning fluid for the windscreen or rear window and for the head-
light cleaning system.
The capacity of the reservoir is about 3 litres or about 4.7 litres on vehicles that
have a headlight cleaning system.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We recommend using clean washing water together with the screen cleaner from
the range of ŠKODA Original Accessories (in winter additionally with antifreeze)
which is capable of removing stubborn dirt.
In Winter, the washing water should always be mixed with antifreeze even if the
vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. The freeze protection at this concentration is sufficient
only to -5 °C.
CAUTION
■ Under no circumstances must radiator antifreeze or other additives be added to
the windscreen washer fluid.■
If the vehicle is fitted with a headlight cleaning system, only cleaning products
which do not attack the polycarbonate coating of the headlights must be added
to the windscreen washer fluid.
■
Do not remove the filter from the windscreen washer fluid reservoir when re-
plenishing it with liquid otherwise the liquid transportation system can be conta-
minated, which can cause the windscreen washer system to malfunction.
