2012 SKODA CITIGO check engine light

WARNING (Continued)
■ If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. Other-
wise, the functionality of the brake system could be impaired – risk of acci-
dent!
■ Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating, which can
have a negative effect on the operation of the brake system – risk of accident!
■ Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle
might then move off – risk of accident!
■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then be without function – risk of acci-
dent!
■ Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems
must not tempt you to take greater risks than otherwise – risk of an accident! ■ The normal braking system is still fully functional if there is an ABS fault.
Visit a ŠKODA specialist garage immediately and adjust your style of driving
according to the damage to the ABS as you will not know how great the dam-
age is and the limitation it is placing on the braking efficiency. CAUTION
■ Observe the recommendations on the new brake pads » page 91.
■ Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear. ■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly. Note
■ If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically. After the speed was reduced below around 10

km/h or the
vehicle was stopped, the brake light stops flashing and the hazard warning light
system switches on. The hazard warning light system is switched off automatical-
ly after accelerating or driving off again. ■ Before negotiating a steep downhill section, reduce the speed, shift down into
the next lower gear (manual gearbox) or select a lower drive position (automatic
gearbox). As a result, the braking effect of the engine will be used, reducing the
load on the brakes. Any additional braking should be completed intermittently,
not continuously. ■ Changes to the vehicle (e.g. to the engine, brakes, chassis or another combina-
tion of tyres and wheels) can influence the functionality of the brake assist sys-
tems »

page 125, Accessories, changes and replacement of parts .
■ If a fault occurs in the ABS system, the ESC, TCS and EDL also do not work. A
warning light  » page 17 comes on if a fault occurs in the ABS system. Ð Information for braking
First read and observe the introductory information and safety warn-
ings on page 58.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving
style. The brake pads wear more quickly if a lot of journeys are completed in
towns and over short distances or if a very sporty style of driving is adopted. If
operated under severe conditions, the thickness of the brake pads must be
checked by a ŠKODA specialist garage before the next service appointment.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads
may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. If the brake system is not used much or if there is corrosion on the sur-
face, we recommend cleaning the brake discs by firmly applying the brakes from a
high speed. £

Fig. 69
Button for the START-STOP sys-
tem
The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the

START-STOP system is indicated in
the display of the instrument cluster.
Automatic engine shut down (stop phase)
› Stop the vehicle (where necessary, apply the handbrake).
› Take the vehicle out of gear.
› Release the clutch pedal.
Automatic renewed engine restart (start phase).
› Depress the clutch pedal.
ä
Switching the START-STOP system on and off
The START/STOP
system can be switched on/off by pressing the button » Fig. 69.
When start-stop mode is deactivated, the warning light in the button lights up.
If the vehicle is in the stop phase when manually switching off the system, the
engine starts immediately.
The START-STOP system is very complex. Some of the procedures are hard to
check without servicing. The general conditions for the proper functioning of the
START-STOP system are listed in the following overview.
Conditions for the automatic engine shut down (stop phase)
› The gearshift lever is in Neutral.
› The clutch pedal is not depressed.
› The driver has fastened the seat belt.
› The driver's door is closed.
› The bonnet is closed.
› The vehicle is at a standstill.
› The engine is at operating temperature.
› The charge state of the vehicle battery is sufficient.
› The stationary vehicle is not on a steep slope or a steep downhill section.
› The engine speed is less than 1 200 rpm.
› The temperature of the vehicle battery is not too low or too high.
› There is sufficient pressure in the braking system.
› The difference between the outdoor- and the set temperature in the interior is
not too great.
› The vehicle speed since the last time the engine was switched off was greater
than 3 km/h.
› The front wheels are not turned excessively (the steering angle is less than 3/4
of a steering wheel revolution).
Conditions for an automatic restart (start phase)
› The clutch is depressed.
› The max./min. temperature is set.
› The defrost function for the windscreen is switched on.
› A high blower stage has been selected.

Starting-off and Driving

Note
Observe the recommended gear » page 10, Recommended gear .ÐAvoiding full throttle
Fig. 92
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h.
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consump-
tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 92 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used. ÐReducing idling
Idling also costs fuel.
In vehicles not equipped with the

START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times. Even af-
ter just 30 – 40 seconds you will have saved more fuel than that is needed when
you start the engine up again. If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started, whereby high engine speeds should be avoided.
Ð Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a ŠKODA

specialist garage, you
create the conditions needed for driving economically. The maintenance state of
your vehicle has a positive effect on traffic safety and value retention
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
Also check the oil level when refuelling. Oil consumption is dependent to a con-
siderable 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. The oil consumption of a
new vehicle can therefore only be correctly assessed after driving about
5 000 km. For the sake of the environment
■ Additional improvements to the fuel economy can be made by using synthetic
high-lubricity oils.
■ Regularly check the ground under the vehicle. Have your vehicle inspected by a
ŠKODA specialist garage if you find any stains caused by oil or other fluids on the
floor. Note
We recommend that your vehicle is serviced on a regular basis by a ŠKODA Serv-
ice Partner. Ð

Driving and the Environment

The fuel tank is full when the compressor of the refuelling system automatically
switches off. To stop the refuelling operation prematurely, press the
“Stop ” but-
ton of the refuelling system.
Closing the filler cap
› Check that the sealing ring 3
» Fig. 96
has remained in the gas filler tube. If it
has slipped onto the filling coupling, reinsert it into the gas filler tube.
› Plug the cap 1
onto the gas filler tube.
› Close the filler cap.
In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined
value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops. WARNING
■ Stop the engine before refuelling.
■ Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!
■ When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling. ■ Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries. Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling). ■ Noises that occur during refuelling represent no risk.
■ If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi-
cate exactly the same level as was the case immediately after refuelling when the
engine is restarted. This is not due to any system leakages but a drop in pressure
in the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling. ■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why
the petrol tank runs empty faster than the natural gas tank.
■ The capacity of the natural gas tank is about 11 kg, of which about 1.5
kg are a
reserve.
■ The capacity of the petrol tank is about 10 l, of which about 5 l
are a reserve.Ð Automatically switching over from CNG mode to petrol mode
First read and observe the introductory information and safety warn-
ings on page 106.
The vehicle automatically switches over from CNG mode to petrol mode when the
following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas. Ð Natural gas as fuel
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive
for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts. Ð

Checking the engine oil level
Fig. 100
Dipstick
First read and observe the introductory information and safety warn-
ings on page 108.
The dipstick indicates the level of oil in the engine
» Fig. 100.
Checking the oil level
› Ensure that the vehicle is positioned on a level surface and the engine has
reached its operating temperature.
› Switch off the engine.
› Open the bonnet.
› Wait a few minutes until the engine oil flows back into the oil sump and remove
the dipstick.
› Wipe the dipstick with a clean cloth and insert it again to the stop.
› Then pull the dipstick out again and check the oil level.
Oil level within range A
›
No oil must be refilled.
Oil level within range B
›
Oil can
be refilled. It is possible that the oil level may then be within range A
after doing this.
Oil level within range C
›
Oil must be refilled. It is sufficient, once this is done, to keep the oil level within
range B
.
It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000

km depending on your style of driving and the conditions under which
you operate your vehicle. Consumption may be slightly higher than this during the
first 5 000 kilometres. ä
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range A
, but not above
, if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun-
tain pass.
The warning light in the instrument cluster will indicate whether the oil level is
too low » page 16 , Engine oil pressure. In this case, check the oil level with the
dipstick, as soon as possible. Add oil accordingly. CAUTION
■ The oil level must on no account extend beyond the range A
» Fig. 100. Risk of
damaging the exhaust system!
■ If it is not possible to top up the engine oil under the prevailing conditions,  do
not continue your journey! Switch off the engine and obtain professional assis-
tance from a ŠKODA specialist garage, otherwise it could cause severe engine
damage. Note

Inspecting and replenishing

Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 108.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil – risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 108.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and also protects the
cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to 60 % (antifreeze protection down
to approx. -40 °C). The antifreeze protection tails off above that concentration.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 101 on page 112.

1.0 ltr./55 kW MPI 4.2
1.0 l/50 kW - CNG 4.2 CAUTION
■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Ð Checking the coolant level
Fig. 101
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 108.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 110.
› Check the level of coolant in the coolant expansion bottle
» Fig. 101. The cool-
ant level when the engine is cold must lie between the
“MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine
is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster » page 16, Coolant tem-
perature/coolant level . We still recommend inspecting the coolant level directly
at the reservoir from time to time. £
ä
112 General Maintenance

Loss of coolant
A loss of coolant is first and foremost an
indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a
ŠKODA spe-
cialist garage immediately. CAUTION
If a fault causes the engine to overheat, we recommend visiting a ŠKODA Service
Partner immediately, otherwise serious engine damage may occur. ÐReplenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 108.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 101 on
page 112 and unscrew the cap carefully.
› Replenish the coolant.
› Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, just use water and have the correct mixing ratio of water
and the coolant additive restored by a ŠKODA

specialist garage as soon as possi-
ble.
Only use new coolant to top up the system.
Do not fill the coolant above the mark “MAX” » Fig. 101 on page 112! Excess cool-
ant heats up and then is forced out of the cooling system through the pressure
relief valve in the cap. WARNING
■ The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to health.
Therefore always safely store the coolant additive in its original container out
of the reach of children – risk of poisoning!
■ If any coolant splashes into your eyes, immediately rinse out your eyes with
clear water and contact a doctor as soon as possible.
■ You should also consult a doctor without delay if you have inadvertently
swallowed coolant.
ä CAUTION
Do not continue your journey, if it is not possible  to top up the coolant under
the prevailing conditions . Contact a

ŠKODA Service Partner to avoid the risk of
serious engine. Ð Radiator fan
First read and observe the introductory information and safety warn-
ings on page 108.
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.
Ð Checking the brake fluid
Fig. 102
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 108.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 110.
› Check the level of brake fluid in the reservoir
» Fig. 102. 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. £
