fuel pump SKODA ROOMSTER 2011 1.G Owner's Manual

For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
When driving the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower. 
Petrol engines These engines are fitted with a starter system which selects the correct fuel-air
mixture for every external air temperature.
●
Do not operate accelerator before and when starting engine.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 179.
● If the engine does not start, contact the nearest specialist garage to obtain
professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started. 
Diesel engines Glow plug system
Diesel engines are equipped with a glow plug system, the pre-glow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The pre-glow indicator light  comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
● You should start the engine immediately after the glow plug warning light 
has gone out.
● The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if the outside temperature is above +5 °C.
This means that you can start the engine right away.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repeating the attempt. ●
It is possible that the fuse on the diesel pre-glow system is defect if the en-
gine still does not start. Check the fuse and replace it if necessary ⇒ page 179.
● Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank
has run completely dry - up to one minute. This is because the fuel system must
first of all be filled while the attempting to start the engine. 
Switching off the engine –
The engine can be switched off by turning the ignition key into position 1 ⇒ 
fig. 78 . WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries. CAUTION
you should not switch the engine off right away at the end of your journey after
the engine has been operated for a lengthy period at high loads but should be al-
lowed it to run at idling speed for about 2
minutes. This prevents any accumula-
tion of heat when the engine is switched off. Note
● The radiator fan may continue running for a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, al-
so switch on again after some time if the coolant temperature rises because of an
accumulation of heat in the engine or if the engine is warm and the engine com-
partment is additionally heated by strong sunlight.
● This is why particular care is required when carrying out any work in the en-
gine compartment ⇒

Starting-off and Driving

–
Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and inflation
pressures are stated on a sticker affixed to the inside of the fuel filler flap. Further
information on fuel ⇒
 page 147.WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and
fuel may leak out. CAUTION
● Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - risk of paint damage!
● On vehicles fitted with a catalytic converter, never let the fuel tank run com-
pletely empty. An irregular supply of fuel to the engine can result in misfiring and
unburnt fuel may get into the exhaust system, which may result in overheating
and damage to the catalytic converter.
● Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwise you are unintentionally filling up the
volume, which in case of heat can cause an expansion of the fuel. This can lead to
an overflow of fuel or damage to parts of the fuel reservoir.
● The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Do not continue refuelling -
otherwise the expansion volume is filled up. Note
The fuel tank has a capacity of about 55 litres, containing a reserve of 7 litres. 149

If the engine is switched off already one electrical component which is connected can discharge the
battery. Replacing fuses at the battery (manual gearbox, automatic
gearbox DSG) Fig. 148 The battery: fuse cover
– Press together the interlocks of the fuse cover simultaneously in direction of
arrow A
⇒  fig. 148 and push out the cover in direction of arrow B .
– Release the fixtures in the openings C using a flat screwdriver and fold the
cover upwards in direction of arrow D .
– Find out which fuse belongs to the component which is not operating.
– Defect fuses can be detected by their melted metal strips. Replace the defect
fuse by a new fuse of the same ampere number. WARNING
Read and observe the warning notes ⇒ page 150 , Working in the engine com-
partment before working in the engine compartment. CAUTION
● Never attempt to
“repair” fuses and also do not replace them with a fuse of a
higher amperage - risk of fire! This may also cause damage at another part of the
electrical system.
● Have the electrical system checked as quickly as possible by a specialist ga-
rage if a newly inserted fuse blows again after a short time. Note
We recommend that you have these fuses replaced by a specialist garage.  181
