2012 SKODA ROOMSTER radiator cap

An audible signal sounds as a warning tone.
The following is displayed in the information display: Check coolant! Owner's manual!
Stop the vehicle, switch off the engine, check the level of the coolant » page 141,
and refill the coolant if necessary » page 141.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the radiator fan. Check the fuse for the radia-
tor fan, replace if necessary » page 168, Fuses in the engine compartment .
Do not continue driving if the warning light   does not go off even though the
coolant level is correct and the fuse for the fan is in working order!
Seek help from a
ŠKODA specialist garage.WARNING
■ If you have to stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warning
light system » page 40.
■ Carefully open the coolant expansion bottle. If the engine is hot, the cooling
system is pressurized - risk of scalding! It is therefore best to allow the engine
to cool down before removing the cap.
■ Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off. ÐElectrohydraulic power steering 
The warning light  comes on for a few seconds when the ignition is switched
on.
If the warning light after switching on the ignition or when driving lights up con-
tinuously, a fault exists in the electrohydraulic power steering. The power steer-
ing operates with reduced steering assist or does not function at all.
Seek help from a

ŠKODA specialist garage.
Further information » page 77. Note
■ If the yellow warning light  goes out when you restart the engine and drive
for a short distance, it is not necessary to visit a

ŠKODA specialist garage.
■ If the vehicle battery has been disconnected and reconnected, the yellow warn-
ing light  comes on after switching on the ignition. The warning light should go
out after driving a short distance. ■ There is no power-assisted steering support when the vehicle is being towed
without the engine running or when the power-assisted steering is defect. The
vehicle is fully steerable however. There is however increased force required to
turn the steering wheel. Ð Electronic Stability Control (ESC) 
The warning light flashes  to show that the ESC is currently operating.
If the warning light  comes on immediately after you start the engine, the ESC
might be switched off due to technical reasons. Switch the ignition off and on
again. If the warning light does not light up after you switch the engine back on,
the ESR is fully functional again.
If the warning light  lights up, there is a fault in the ESC.
The following is displayed in the information display: Error: Electronic Stability Control (ESC)
Seek help from a ŠKODA specialist garage.
The ESC cannot be switched off, the button  » page 81
only deactivates the
TCS system and the warning light  in the instrument cluster lights up.
As the ESC operates in conjunction with the ABS, the ESP indicator light will also
come on if the ABS system fails.
Further information » page 80, Stabilisation control (ESC) . Note
If the vehicle's battery has been disconnected and reconnected, the warning light  comes on after switching on the ignition. The warning light should go out after
driving a short distance. Ð
20 Using the system

Diesel fuel
First read and observe the introductory information and safety warn-
ings on page 134.
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. £
136 General Maintenance

Windscreen washer system
Fig. 119
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn-
ings on page 136.
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 capacity of the reservoir is about 3.5 litres or about 5.4
litres on vehicles that
have a headlight cleaning system.
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
