£
118 Using the system

Avoid short distances
Fig. 153
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an 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 consump-
tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 153 shows the different levels of fuel consumption after driving a cer-
tain distance at a temperature of +20 °C and a temperature of -10 °C. Your vehicle
has a higher fuel consumption in the winter than in the summer. ÐChecking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. The rolling resistance will be
increased if the tyre filling pressure is too low. This will not only increase fuel con-
sumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold. ÐAvoid unnecessary ballast
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. It is worth checking
the boot to avoid transporting any unnecessary ballast. 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, your vehicle that is fitted with a roof rack cross
member without a load will use use about 10 % more fuel than normal due to the
increased aerodynamic drag.
Ð Saving electricity
When the engine is running, the alternator generates and supplies electrical pow-
er. 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. Ð 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.
› No cadmium.
› No asbestos.
› Reduction in the “vaporisation” of plastics.
Manufacture › Solvent-free cavity protection.
› Solvent-free protection of the vehicle for transportation from the production
plant to the customer. £

The correct type of fuel for your vehicle and the tyre size and inflation pressure
are specified on the inside of the fuel filler flap » Fig. 155 on page 174 - . WARNING
The national legal requirements must be observed if carrying a spare canister
in the vehicle. We do not recommend carrying any fuel canisters in your vehi-
cle for safety reasons. In the event of an accident, the canister might be dam-
aged and fuel may leak out - risk of fire! CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring, which can result in considerable damage to parts of the en-
gine and exhaust system. ■ Immediately remove any fuel that has spilled onto the vehicle's paintwork - risk
of paint damage! Ð Refuelling

WARNING
■ During the first 500 km, new tyres do not offer optimum grip and appropri-
ate care should therefore be taken when driving - risk of accident!
■ Never drive with damaged tyres - risk of accident!
■ Only use those tyres or wheel rims which have been approved by ŠKODA for
your model of vehicle. Failure to observe this instruction will adversely affect
the road safety of your vehicle - risk of accident!
■ The maximum permissible speed for your tyres must not be exceeded under
any circumstances - risk of an accident resulting from tyre damage and loss of
control of the vehicle.
■ If the inflation pressure is too low, the tyre must perform a higher rolling re-
sistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and a tyre blowout. WARNING (Continued)
■ Do not, where possible, replace individual tyres but at least replace them on
both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
■ Never use tyres if you do not know anything about the condition and age.
■ You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■ Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience
“aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
■ Immediately replace damaged wheel rims or tyres.
■ Do not use summer or winter tyres that are older than 6 years or 4 years re-
spectively.
■ The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
■ If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
■ In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
■ Observe the national legal regulations relating to the use of tyres and snow
chains. CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 190, Spare wheel.
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ Protect the tyres from contact with oil, grease and fuel.
■ Replace any lost valve caps immediately. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. £

Wheels and Tyres

Note
■ We recommend that any work on the wheels or tyres is carried out by a ŠKODA
Service Partner. ■ We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from
ŠKODA Original Accessories. ÐService life of tyres
Fig. 164
Tyre tread with wear indicators/Open fuel filler flap with a table de-
tailing the tyre size and tyre inflation pressure
First read and observe the introductory information and safety warn-
ings on page 187.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are located multiple times depending on the make and are
evenly spaced around the circumference of the tyre » Fig. 164 - . Markings on
the walls of the tyres through the letters

“TWI”, triangular symbols or other sym-
bols identify the position of the wear indicators.
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle. Therefore check the tyre pressure, including that of the spare wheel,
at least once a month and also before setting off on a long journey.
ä The tyre inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap » Fig. 164 - . The inflation pressures for winter tyres are 20

kPa
(0.2 bar) higher than those for summer tyres.
The tyre inflation pressure for tyres of the tyre size 205/50 R17 that are designed
to be used with snow chains, is identical to the tyre inflation pressure for tyres of
the tyre size 225/45 R17.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. The tyre inflation pressure of the spare wheel R 18 is 420 kPa.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres. If the load varies greatly, adjust the tyre inflation
pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. In the
event of any unusual tyre wear, seek assistance from a ŠKODA specialist garage.
Tyre damage
Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel
trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies from the tyre
profile.
Unusual vibrations or pulling of the vehicle to one side could be a sign of tyre
damage. If there is any doubt that a wheel is damaged, immediately reduce your
speed and stop! Check the tyres for signs of damage (bulges, splits, etc.). If no ex-
ternal damage is evident, drive slowly and carefully to the nearest ŠKODA special-
ist garage to have the vehicle checked. Ð
188 General Maintenance

Unidirectional tyres
First read and observe the introductory information and safety warn-
ings on page 187.
The direction of rotation of the tyres is marked by arrows on the wall of the tyre
.
The so specified running direction must absolutely be complied with. Only then
are the tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre with-
out a dedicated running direction or the opposite running direction, drive carefully
as the optimum characteristics of the tyre are no longer applicable in this situa-
tion. ÐSpare wheel
Fig. 166
Boot: Spare wheel
First read and observe the introductory information and safety warn-
ings on page 187.
The spare wheel is located in a well under the floor covering in the boot and is
fixed in place with a special bolt » Fig. 166.
Before removing the spare wheel, the box containing the vehicle tool kit must be
removed.
It is important to check the inflation pressure in the spare wheel (preferably every
time the tyre air pressure is checked - see sticker on the fuel filler flap »
page 188)
to ensure it is always ready to use.
ä
ä If the dimensions or design of the spare wheel differ from the tyres fitted to the
vehicle (e.g. winter tyres or low-profile tyres), it must only be used briefly in the
event of a puncture and if an appropriately cautious style of driving is adop-
ted » .
Replace it with a wheel having the appropriate mode and dimensions as soon as
possible
Temporary spare wheel
A warning label is displayed on the wheel rim of the spare wheel to indicate that
your vehicle is equipped with a temporary spare wheel.
Please observe the following when driving with a temporary spare wheel.
› The warning label must not be covered after installing the wheel.
› Do not drive faster than 80

km/h with the temporary spare wheel and pay par-
ticular attention while driving. Avoid accelerating at full throttle, sharp braking
and fast cornering.
› The inflation pressure for this spare wheel is identical to the maximum inflation
pressure of the standard tyres.
› Only use this temporary spare wheel to reach the nearest ŠKODA specialist ga-
rage as it is not intended for continuous use.
› No other summer or winter tyres must be mounted on the rim of the temporary
spare wheel R 18. WARNING
■ Never use the temporary spare wheel if it is damaged.
■ If the dimensions or design of the temporary spare wheel differ from the fit-
ted tyres, never drive faster than 80
km/h (or 50 mph). Avoid accelerating at
full throttle, sharp braking and fast cornering. CAUTION
Observe the instructions on the sticker on the temporary spare wheel. Note
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. Ð

› If you cannot reach an air pressure of 2.0 – 2.5 bar, unscrew the tyre inflation
hose 5
from the tyre valve.
› Drive the vehicle 10 metres forwards or backwards to allow the sealing agent to
“distribute” in the tyre.
› Firmly screw the tyre inflation hose 5
back onto the tyre valve and repeat the
inflation process.
› If you cannot reach the required tyre inflation pressure here either, this means
the tyre has sustained too much damage. You cannot seal with tyre with the
breakdown kit » .
› Switch off the air compressor.
› Remove the tyre inflation hose 5
from the tyre valve.
Once a tyre inflation pressure of 2.0

– 2.5 bar is achieved, continue the journey at
a maximum speed of 80 km/h (50 mph).
Check the tyre inflation pressure after driving for 10 minutes » page 202.WARNING
■ During inflation, the tyre inflation hose and air compressor may get hot- risk
of injury! ■ Do not place the hot tyre inflation hose or hot air compressor on flammable
materials - risk of fire!
■ If you cannot inflate the tyre to at least 2.0 bar, this means the damage sus-
tained was too serious. The sealing agent cannot be used to seal the tyre. Do
not drive the vehicle. Get professional assistance! CAUTION
Switch off the air compressor after running 8 minutes at the latest - danger of
overheating! Allow the air compressor to cool a few minutes before switching it
on again. Ð Check after driving for 10 minutes
First read and observe the introductory information and safety warn-
ings on page 200.
Check the tyre inflation pressure after driving for 10 minutes!
If the tyre inflation pressure is 1.3 bar or less:
›  Do not drive the vehicle!
You cannot properly seal with tyre with the break-
down kit.
› Get professional assistance.
If the tyre inflation pressure is 1.3 bar or more:
