Note
■ The engine can only be started with a genuine ŠKODA key with the matching
code. ■ The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem. ■ After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10
minutes.
■ If the engine does not start up after a second attempt, the fuse for the fuel
pump/glow plug system (Diesel engines) may have a fault. Check the fuse and re-
place, if necessary » page 190, Fuses in the dash panel

or seek assistance from a
ŠKODA specialist garage.
■ We recommend locking the steering wheel whenever leaving the vehicle. This
acts as a deterrent against the attempted theft of your car. ÐAdjusting the steering wheel position

ä Electromechanical power steering
First read and observe the introductory information and safety warn-
ings on page 91.
The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). However, greater physical effort is
required to turn the steering wheel.
If there is a fault in the power steering, the warning light  or  lights up in the
instrument cluster » page 21, Electromechanical power steering   . Ð Electronic immobiliser
First read and observe the introductory information and safety warn-
ings on page 91.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock. The
electronic immobiliser is automatically activated when the ignition key is with-
drawn from the lock.
The engine will not start if a non-authorized ignition key is used.

Diesel fuel
First read and observe the introductory information and safety warn-
ings on page 155.
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).
Operation in winter - Winter-grade diesel fuel
In the winter, only use 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). “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 ŠKODA Service Partners
and filling stations in the relevant country will be able to provide you with infor-
mation 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!
■ 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 Service 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. Ð

There is a risk of injuries, scalding, accidents and fire when working in the en-
gine compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safety. The vehicle's engine compartment is
a hazardous area . WARNING
■ 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.
■ Turn off the engine and withdraw the ignition key.
■ 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 selec-
tor lever into position P .
■ Firmly apply the handbrake.
■ Allow the engine to cool.
■ For safety reasons, the bonnet must always be properly closed when driving.
This is why after closing the bonnet, the lock must always be checked to en-
sure it has engaged properly. £
158 General Maintenance

WARNING (Continued)
■ 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!
■ Keep children clear of the engine compartment.
■ Do not touch any hot engine parts - risk of burns!
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
■ Avoid short circuits in the electrical system - particularly on the vehicle's
battery.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running! ■ 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 cool-
ant.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ 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!
■ If any inspection work has to be carried out when the engine is running,
there is an additional risk from rotating parts (e.g. V-belt, alternator, radiator
fan) and the high-voltage ignition system. The following must also be ob-
served: ■Never touch the electric wiring on the ignition system.
■ 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.
■ Additionally, the following warning instructions must be observed if work
has to be carried 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. 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 - danger of causing damage. 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
Service Partner as part of the inspection service. Note
■ If you have any questions regarding the fluids, visit a
ŠKODA Service Partner.
■ Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories. Ð

General Maintenance

Radiator fan
First read and observe the introductory information and safety warn-
ings on page 158.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.
ÐChecking the brake fluid
Fig. 136
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 158.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 160.
› Check the level of brake fluid in the reservoir
» Fig. 136. The level must be be-
tween the “MIN” and “MAX” markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal.
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 19, Brake system .
ä
ä WARNING
If the fluid level has dropped below the MIN marking,  do not continue your
journey - risk of accident! Seek help from a
ŠKODA specialist garage.Ð Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 158.
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 system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with the following standards or specifications:
› VW 50114;
› FMVSS 116 DOT4. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. Ð

164 General Maintenance

Windscreen washer system
Fig. 137
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn-
ings on page 158.
The windscreen washer fluid reservoir contains the cleaning fluid for the wind-
screen or rear window and for the headlight cleaning system. The windscreen
washer fluid reservoir is located in the engine compartment.
The filling level of the container is about 3
litres and about 5.5 litres on vehicles
that have a headlight washing system 1)
.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We therefore recommend using clean water with a screen cleaner (including anti-
freeze in the winter) that is able to remove stubborn dirt.
Antifreeze should always be added to the cleaning water in the winter even if the
vehicle is fitted with 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.
ä Note
Do not remove the filter from the windscreen washer fluid reservoir when replen-
ishing it with liquid otherwise the liquid transportation system can be contamina-
ted, which can cause the windscreen washer system to malfunction. Ð Vehicle battery
