Caution
•
Even inadvertently filling the fuel tank
with another biofuel such as Ethanol°E85
can result in damage to the fuel system.•
If you park the car for a lengthy period,
fill with petrol complying with (DIN)
EN°228, because Ethanol E85 can contain lo
w quantities of impurities, which can
lead to corrosion.
For the sake of the environment
If you use Ethanol E85, the CO
2 emission of your vehicl
e is lowered up to 5%.
Note
•
When operating with Ethanol E85, the
fuel consumption increases by approx
33%, as a lower quantity of energy is contained in the bioethanol than in unleaded petrol.•
Biofuel Ethanol E85 contains only a low
quantity of additives in contrast to
unleaded petrol. Therefore we recommend to
fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g. before the oil change) and run it empty, so that the engine remains clean. Make sure not to use the whole content of the tank
⇒page 222, “Refuelling”.
•
The interval of 15 000 km applies for the oil change.
Operation in winterIf you use biofuel Ethanol E85 at very low
temperatures, it is necessary to preheat
the engine before an engine start. The power socket for the engine preheating
is located in the front bumper next to
the fog light
⇒fig. 204
.
If an engine preheating is
not possible at outside temperatures lower than -10 °C,
the share of unleaded petrol complying with
EN 228 must be as high as possible.
Thus the cold start property of the engine is clearly improved. If there is biofuel Ethanol E
85 in the tank and the engine is not preheated, it can lead
at temperatures below -15°C to very poor or no starting of the engine.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on the fuel consumption and thus on the environment.The outside temperature

diesel fuel
, which complies with the standard
DIN EN 590
.
Fuel additives You must not use fuel additives, so-called “flow improvers” (petrol and similar products) in diesel fuel. If the quality of the diesel fuel is p
oor, it is then necessary to drain the
fuel filter

more often than stated in the Service schedule. You can find information on refuelling
⇒page 222, “Refuelling”.
Caution
•
Only use fuel which complies with the standard
DINEN590
. Filling the tank
even only once, which does not comply with
the standard, can result in damage to
the fuel system.•
Water which has collected in the fuel fi
lter can result in engine problems.
•
Your vehicle is not adapted for use of biodiesel, therefore this fuel must not be
refuelled and driven. Using this biodiesel ca
n lead to damage to the engine or the
fuel system.
Operation in winterWinter-grade diesel fuel A different grade of diesel fuel is available at filling stations in winter than during the summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in operational problems because the diesel be
comes viscous as a result of paraffin
separation. It is therefore the case that DIN EN 590
prescribes diesel fuel class for certain
periods of the year which can also be pu
rchased at the corres
ponding time during
the year. “Winter-grade diesel fuel” will still operate properly 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 authorised Škoda Service Partners and filling stations in the country concerned will be able to provide you with information regarding the diesel fuels available. Prewarming fuel The vehicle is fitted with a fuel filter prewarming system. This secures operation of a vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel
additives on the market, including petrol,
to diesel fuel in order to
improve its flow properties.

to keep the oil level within range .
It is normal for the engine to consume oi
l. 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. The oil consumpt
ion may be slightly higher than this
during the first 5 000 kilometres. One should therefore check the oil level at regular intervals, preferably every time after the fuel tank is filled or after driving for long stretches. We recommend maintaining the oil level within the range -
but not above this
,
if the engine has been operating at hi
gh loads, for example during a lengthy
motorway trip during the summer months,
towing a trailer or negotiating a high
mountain pass. The warning light in the instrument cluster* will indicate

Wheels and TyresWheelsGeneral information•
New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving. You will also profit from longer tyre life.•
The tread depth of new tyres may differ because of design features and the
configuration of the tread (d
epending on the type of tyre and the manufacturer).
•
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.
•
Inspect your tyres from time to time
for damage (punctures, cuts, splits and
bulges). Remove foreign bodi
es from the tyre profile.
•
Damage to tyres and wheels is frequent
ly not visible. Unus
ual vibrations or
pulling of the vehicle to one side
could be a sign of tyre damage.
Please reduce
your speed immediately and stop if
you suspect that a wheel is damaged.

Inspect the tyres for signs of damage (bulges,
splits, etc.). If no
visible damage is
present, please drive at an appropriately slow speed and carefully to the nearest specialist garage in order to have your vehicle inspected.•
Also protect your tyres from cont
act with oil, grease and fuel.
•
Immediately replace any dust caps of
the valves which have got lost.
•
Mark wheels before removing them so th
at their previous direction of running
can be maintained when
mounted them again.
•
Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not
fixed to a wheel trim should be stored
upright. Unidirectional tyres* The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This indicates the direction of rotation of the tyre, and it is essential that the tyres are fitted on to run in this direction. Only then are the tyres able to provide the optimal properties in terms of grip, low no
ise, wear-and-tear and aquaplaning.
Further information concerning th
e use of unidirectional tyres
⇒page 242.
WARNING
•
New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!•
Never drive with damaged tyres - risk of accident!Note
Please observe the various differing legal requirements regarding tyres.Tyre lifeThe life of your tyres very much depends on the following points: Tyre pressure The working life of tyres will be shortened co
nsiderably if the tyres are insufficiently
or over-inflated and this will have an advers
e effect on the handling of your vehicle.
Correctly inflated tyres are of partic
ular importance when travelling at
high speeds
.
It is therefore good to check the pressure
at least once a month and also before

setting off on a long trip. Please do not
forget the spare wheel when checking the
tyres. The tyre inflation pressures for
summer tyres
are indicated on the inside of the fuel
filler flap
⇒page 238, fig. 218
. The inflation pressures for
winter tyres
are 20 kPa
(0.2 bar) higher than those for summer tyres
⇒page 242.
The tyre pressure should be at the highest pressure specified for your vehicle at all times. The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).Always check the inflation pressure of ty
res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your vehicle is carrying a significantly higher payload. Driving style Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-and- tear on 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 im
balance and which makes themselves felt
through vibration in the steering. You should have the wheels rebalanced since any imbalance increases wear-and- tear on the steering, the suspension and tyres. A wheel must also be rebalanced when a new tyre is fitted and each time a tyre is repaired. 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. Contact your specialist garage if you no
tice any unusual tyre wear.
WARNING
•
If the inflation pressure is too low,
the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can result in tread separation and even a tyre blowout.•
Immediately replace the damaged rims or tyres.
•
Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an appropriately cautious style of driving.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.Wear indicatorsThe base of the tread of the original tyres has wear indicators 1.6 mm high, installed at right angles to the direction of travel. These wear indicators are located at 6 - 8 points depending on the make and are evenly spaced around the circumference of the tyre
⇒fig. 219
. Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identi
fy the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the wear indicators, means that your tyres have reached their legally permissible minimum tread depth.

•
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 lossen 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 permanent deformation of the contact surfaces on the rims.
Caution
The prescribed tightening torque of the wheel bolts for steel and light alloy wheels is 120 Nm.Winter tyresThe handling of your vehicle will be signi
ficantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow and at temperatures below 7 °C because of
their construction (width, rubber blend,
tread pattern). This particularly applie
s to vehicles which
are equipped with
low-
profile tyres
or high-speed tyres
(code index H or V on wall of tyre).
Winter tyres must be mounted on all four
wheels to obtain the
best handling char-
acteristics. You must only fit those types of winter tyre
which are approved for your vehicle. The
permissible
sizes of winter tyres
are stated in your vehicle documents. Approvals
may differ because of
national legislation.
Please remember that the tyres should be in
flated to 20 kPa (0.2 bar) more than is
the case for summer tyres
⇒page 238.
Winter tyres no longer offer the
same winter performance once the
tyre tread
has
worn down to a depth of about 4 mm. Ageing
a l s o c a u s e s w i n t e r t y re s t o l o s e m o s t
of their winter performance properties
- even in cases where the remaining tread depth is still clearly more than 4 mm. Speed restrictions
apply to winter tyres as
well as to summer tyres
⇒page 240,
⇒
.
You can fit winter tyres of a lower speed ca
tegory to your vehicle provided that you
also do not drive faster than the permissible maximum speed for such tyres, even if the possible maximum speed of your ve
hicle is higher. The
corresponding tyre
category can damage the tyres when ex
ceeding the permissible maximum speed.
Please pay attention to the notes if
you decide to fit winter tyres
⇒page 238.
You can also fit so-called “all-year tyres” instead of winter tyres.Please contact your specialist garage if there are any points which are not clear who will be able to provide you with information regarding the maximum speed for your tyres.
WARNING
You must on no account drive your car at more than the permissible maximum speed for your winter tyres -
risk of an accident resulting from
tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you better grip and handling on roads which are free of snow and ice as well as ar tempera- tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.Unidirectional tyres*The direction of rotation of the tyres is marked by
arrows on the wall of the tyre
.
This indicates the direction of
rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. On
