
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.

WARNINGWhen working in the engine compartment, injuries, scolding, accident or fire
hazards may arise. For this reason, it is essential to comply with the warning
instructions stated below and with the general applicable rules of safety. The
engine compartment of your car is a hazardous area!■
Before beginning work in the engine compartment, please read the follow-
ing advice. ■ Turn off the engine and withdraw the ignition key.
■ Firmly apply the handbrake.
■ If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the se- lector lever into position P.
■ Allow the engine to cool.
■ Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment – risk of scalding! Wait until the steam or coolant has stopped escaping.
■
While working in the engine compartment, please read the following advice.
■ Keep children clear of the engine compartment.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■ Do not touch any hot engine parts – risk of burns!
■ The coolant additive and thus all of the coolant is harmful to your health.
■ Avoid contact with the coolant.
■ Coolant vapours are harmful to health.
■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot coolant. ■ If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■ Always safely store the coolant additive in its original container out of the
reach of children – risk of poisoning!
■ If coolant is swallowed - consult a doctor immediately.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
WARNING (Continued)■ Whenever working in the engine compartment while the engine is running,
you must pay heed to the following warning instructions. ■Pay particular attention to moving engine parts (e.g. V-ribbed belt, alterna-
tor, radiator fan) and the high-voltage ignition unit - danger to life! ■ Never touch the electric wiring on the ignition system.
■ Avoid short circuits in the electrical system – particularly on the vehicle's
battery. ■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts – hazard! Always remove any jewellery, tie back long hair and wear tight fitting clothing before completing any work.■
The following warning instructions must be observed if work has to be car-
ried out on the fuel or electrical system. ■ Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby.
■
Read the information and warning instructions on the fluid containers.
■
Keep fluids in their original containers and keep out of reach of children!
■
If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this – risk of injury!
■
The bonnet must always be properly closed when driving. This is why after
closing the bonnet, the lock must always be checked to ensure it has engaged
properly.
■
If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet – risk of an accident!
CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!■
Never open the bonnet using the locking lever.
For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda Partner as part of the inspection service. 170General Maintenance

Note■If there is anything you are not sure about concerning fluids, please consult a

First read and observe the introductory information and safety warn-
ings on page 169.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of brake fluid in the reservoir » Fig. 151. The level must be be-
tween the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the brake pads.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking.
If the brake fluid level is too low, this is indicated by the warning light 
lighting
up in the instrument cluster » page 14, Brake system 
.

175Inspecting and replenishing

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.
