2011 SKODA ROOMSTER fuel pressure

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 118 Fuel consumption in litres/100
km at different temperatures
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒  fig. 118 shows the different fuel consumptions for the same distance, on the one
hand at +20 °C and on the other hand at -10
°C. Your vehicle has a higher fuel con-
sumption in winter than in summer. 
Checking tyre inflation pressures Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold. £ 135

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

Wheels and Tyres
Wheels
General information ●
New tyres do not offer optimal grip at first. They should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
● The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
● Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel trims.
● We recommend you Inspect your tyres and rims from time to time for damage
(punctures, cuts, splits and bulges). Remove foreign bodies from the tyre profile.
● Damage to tyres is frequently not visible. Unusual vibrations or pulling of the
vehicle to one side could be a sign of tyre damage. Please reduce your speed im-
mediately and stop if you suspect that a wheel is damaged. Inspect the tyres for
signs of damage (bulges, splits, etc.) If no visible damage is present, please drive
at an appropriately slow speed and carefully to the nearest specialist garage in or-
der to have your vehicle inspected.
● Also protect your tyres from contact with oil, grease and fuel.
● Immediately replace any dust caps of the valves which have got lost.
● Mark wheels before removing them so that their previous direction of running
can be maintained when mounted them again.
● Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres
The direction of rotation of the tyres is marked by arrows on the wall of the tyre.
This indicates the direction of rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. Only then are the tyres able to provide the
optimal properties in terms of grip, low noise, wear-and-tear and aquaplaning.
Further information concerning the use of unidirectional tyres ⇒

 page 165. WARNING
● New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
● Never drive with damaged tyres - risk of accident! Note
Please observe the various differing legal requirements regarding tyres. 
Tyre life Fig. 130 An opened fuel filler flap with a
tyre size and tyre inflation pressure ta-
ble
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle.
Correctly inflated tyres are of particular importance when travelling at high
speeds . It is therefore good to check the tyre pressure, including that of the spare
wheel, at least once a month and also before setting off on a long trip.
The tyre inflation pressures for summer tyres are indicated on the inside of the
fuel filler flap ⇒ fig. 130 . The inflation pressures for winter tyres are 20 kPa
(0.2

bar) higher than those for summer tyres ⇒ page 164.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. £ 161

Always check the inflation pressure of tyres when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if
your vehicle is carrying a significantly higher payload.
Tyre inflation pressure - Tyre size 185/55

The same inflation pressure values apply to tyres of the tyre size 195/55 R15 as to
tyres of the tyre size 185/55 R15 which are intended to be used with snow chains,
see the inside of the fuel filler flap.
The tyres of the tyre size 185/55 R15, which are intended to be used with snow
chains and are fitted on models Roomster Scout, have the following inflation
pressure values in kPa. Engine Partial load Full load

Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-
and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. Contact
your specialist garage if you notice any unusual tyre wear. WARNING
● If the inflation pressure is too low, the tyre must perform a higher rolling
resistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
● Immediately replace the damaged rims or tyres.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. 
Wear indicators Fig. 131 Tyre tread with wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, instal-
led at right angles to the direction of travel. These wear indicators are located at 6
- 8 points depending on the make and are evenly spaced around the circumfer-
ence of the tyre ⇒ fig. 131. Markings on the walls of the tyres through the letters
“TWI”, triangular symbols or other symbols identify the position of the wear indi-
cators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible mini-
mum tread depth. £162

● Ensure that the vehicle tool kit is safely attached in the luggage compart-
ment. 
Spare wheel The spare wheel is stowed in the spare wheel well in the luggage
compartment below the floor covering.
Fig. 134 Luggage compartment: Spare
wheel
The spare wheel lies in a well under the floor covering of the luggage compart-
ment and is fixed in place along with a vehicle tool kit box using a special screw
⇒  fig. 134. One should check the inflation pressure in the spare wheel (at best when general-
ly checking the tyre air pressures - see sign on the fuel filler flap
⇒ page 148
) to
ensure that the spare wheel is always ready to use.
Unidirectional tyres
If you have such tyres on your vehicle, please refer to the notes below:
● The spare wheel provided with a car fitted with unidirectional tyres has differ-
ent dimensions. The wheel is provided with a warning sticker.
● The warning label must not be covered after installing the wheel.
● Do not drive faster than 80 km/h with this spare wheel and pay particular at-
tention while driving. Avoid accelerating at full throttle, sharp braking and fast
cornering.
● The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres.
● Use this spare wheel only to reach the nearest specialist garage as it is not in-
tended for continuous use. 
Changing a wheel Preliminary work The following steps should be carried out before actually changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible
from the traffic flow. The place you choose should be level.
– Have all the occupants get out. While changing a tyre, the occupants of the
vehicle should not stand on the road (instead they should remain behind a
crash barrier, for example).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic gearbox, position
the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒

CAUTION
Switch off the air compressor after running 8 minutes at the latest - danger of
overheating! Allow the air compressor to cool a few moments before switching it
on again. 
Check after driving for 10 minutes Check the tyre inflation pressure after driving 10 minutes.
If the tyre inflation pressure is 1.3 bar or less:
–
Do not drive the vehicle! You cannot properly seal with tyre with the break-
down kit.
– Contact a Škoda dealer to obtain professional assistance.
If the tyre inflation pressure is 1.3 bar or more:
– Adjust the tyre inflation pressure to the correct value (see inside of fuel filler
cap).
– Continue driving carefully to the nearest specialist garage at a maximum
speed of 80 km/h (50 mph). 
Jump-starting Initial steps You can use the battery of another vehicle for jump-starting yours if the engine
does not start because the battery on your vehicle is flat. You will require jump-
start cables for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity
(Ah) of the battery
supplying the power must not be significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Please pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable -
colour coding in the majority of cases black. WARNING
● A discharged battery may already freeze at temperatures just below 0 °C.
In case of frozen battery carry out no jump-starting - risk of explosion! Also af-
ter thawing of the battery there is a risk of caustic burns due to leaking acid.
Replace the frozen battery.
● Please pay attention to the warning instructions relating to working in the
engine compartment ⇒ page 150

. Note
● There must not be any contact between the two vehicles otherwise current
may flow as soon as the negative terminals are connected.
● The discharged battery must be properly connected to the system of the vehi-
cle.
● Switch off the car phone. Heed the advice concerning the use of mobile
phones in such a situation.
● We recommend you buy jump-start cables from a car battery specialist. 

Fuel consumption according to the ECE standards
and EU guidelines Depending on the range of the special equipment, style of driving, traffic situa-
tion, weather influences and vehicle condition, the consumption values which in
practice result when using the vehicle can deviate from the indicated values.
Urban traffic
The consumption measurement in urban traffic begins with starting of the cold
engine. Afterwards the normal urban traffic is simulated.
Non-urban traffic
For the consumption measurement in non-urban traffic the vehicle, as in daily mo-
toring, is accelerated and braked several times in all gears. The vehicle speed
changes within the range from 0 to 120 km/h.
Combined traffic
The consumption value in the combined traffic consists of 37 % from the value for
the urban traffic and of 63 % from the value for the non-urban traffic. 192
