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

›Hold the fuel filler cap on the fuel filler tube with one hand and lock it by turn-
ing the vehicle key to the right and remove the key.›
Close the fuel filler flap until it clicks into place.
›
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel engines The fuel filler tube on vehicles with diesel engines has been fitted with a incor-
rect refuelling guard » Fig. 145. This guard means it is only possible to refuel with
the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to and fro with slight pressure to insert it correctly.
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue filling the fuel tank otherwise the expansion volume is filled up.■
Before refuelling, switch off the auxiliary heating system (auxiliary heating and
ventilation).
■
Be careful when filling diesel fuel from the spare canister - danger of contami-
nating the body.
Note
The fuel tank has a capacity of about 50 litres, containing a reserve of approx.
7 litres .
Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 167.
Your vehicle can only be operated with unleaded fuel that complies with the
standard EN 228 (in Germany: standard DIN 51626-1 or E10 for unleaded fuel with
an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel
with the octane rating 95 RON and 98 RON).
Prescribed fuel – unleaded fuel 95/91 RON Use unleaded fuel with the octane rating 95 RON. Unleaded petrol 91 RON can al-
so be used but results in a slight loss in performance.
Prescribed fuel – unleaded petrol min. 95 RONUse unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Unleaded petrol with higher octane number
Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power in-
crease or a lower fuel consumption.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.
Prescribed fuel – unleaded petrol 98/(95) RON
Use unleaded fuel with the octane rating 98 RON. Unleaded petrol 95 RON can
also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98 RON or 95 RON is not available.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Fuel additives
Only use unleaded petrol, which complies with the standard EN 228 (in Germany:
standard DIN 51626-1 or E10 for unleaded fuel with an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel with an octane rating of
95 RON and 98 RON), as these meet all of the requirements for fault-free engine operation. We therefore recommend that no fuel additives are used.
CAUTION
■ All ŠKODA vehicles with petrol engines must only be operated with unleaded
petrol. Just filling the tank with leaded petrol once will damage the exhaust sys-
tem!■
If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible. 
168General Maintenance

CAUTION■If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 184, Spare wheel .■
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost dust caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
without a dedicated running direction or the opposite running direction, drive carefully as the optimum characteristics of the tyre are no longer applicable in
this situation.
■
The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure.
■
The system cannot warn in case of very rapid tyre inflation pressure loss, e.g. in
case of sudden tyre damage. In this case carefully bring the vehicle to a standstill
without sudden steering movements or sharp braking.
■
To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10 000 km or once a year.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Note
■ We recommend that any work on the wheels or tyres is carried out by a ŠKODA
Partner.■
We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from ŠKODA Original Accessories.

tailing the tyre size and tyre inflation pressure
Fig. 156
Changing wheels around
First read and observe the introductory information and safety warn-
ings on page 181.
The life of tyres depends on the inflation pressure, driving style, and other cir-
cumstances. If you follow the advice below you can extend the life of your tyres.
Tyre pressure
Check the tyre pressure, including that of the spare wheel, at least once a month and also before setting off on a long journey.
The tyre inflation pressures for summer tyres are indicated on the inside of the
fuel filler flap » Fig. 155 –
. The inflation pressures for
winter tyres are 20 kPa
(0.2 bar) higher than those for summer tyres.
The tyre pressure should be at the highest pressure specified for your vehicle at all times. 
182General Maintenance

While pressing the button, the warning light  lights up. At the same time the
system memory is erased and the new calibration is started, which is confirmed
with an audible signal and then the warning light  goes out.
If the warning light  does not go out after the calibration, this indicates a sys-
tem fault. Seek help from a ŠKODA specialist garage.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the spare wheel is mounted;
› one wheel per axle was changed.WARNING■
When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.■
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.

Wheel bolts
First read and observe the introductory information and safety warn-ings
on page 181.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels, e.g. light alloy wheels or wheels with winter tyres, you must
also use the matching wheel bolts of the correct length and shape of spherical cap. This is essential to ensure that the wheels are tightly fitted and that the
brake system operates properly.

Winter tyres
First read and observe the introductory information and safety warn-
ings
on page 181.
The handling of your vehicle will be significantly improved when driving on wintry roads if you fit winter tyres. Summer tyres on ice, snee and at temperatures be-
low 7 °C have less grip. This is especially true of low-profile tyres or high-speed
tyres .
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4 mm and tyres must be no older than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher.
The winter tyres speed limit is set in the menu » operating instructions for Info-
tainment , chapter Setting vehicle systems (CAR button) .
For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roadswhich are free of snow and ice as well as at temperatures above 7 °C. The fuelconsumption is also lower.
Snow chains
First read and observe the introductory information and safety warn-
ings
on page 181.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the following wheel/tyre combinations.
Wheel sizeDepth (D)Tyre size6J x 15 a)43 mm195/65 R156J x 16 b)48 mm205/55 R166J x 17b)48 mm205/50 R17a)
Only fit snow chains with links and locks not larger than 13 mm.
