22Using the system

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!■
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 you
have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ Your vehicle cannot be operated with 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.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the en-
gine or the exhaust system.

Windscreen washer system
Fig. 183
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn- ings on page 215.
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-
lights.
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. 

223WARNING■ The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 215.■
If the fluid level has dropped below the MIN marking » Fig. 186 on page 223,
 do not continue your journey - risk of accident! Seek help from a specialist
garage.
■
Do not use used brake fluid - the function of the brake system may be im-
paired – risk of accident!

reservoir
First read and observe the introductory information and safety warn-
ings on page 223.
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. 186.
The level must be between 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 indicator light  » page 16 , 
Brake system lighting up in the instrument cluster.

Changing
First read and observe the introductory information and safety warn-ings
on page 223.
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. 
