2012 SKODA CITIGO check engine

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.

Starting-off and Driving

Driving Tips
Driving and the Environment
The first 1 500 km
New engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres › Do not drive faster than 3/4 of the maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
› No full throttle.
› Avoid high engine speeds.
› Do not tow a trailer.
From 1 000 up to 1
500 kilometres
› Gradually
increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1

500 kilometres plays a decisive part in the success of
running in your car.
Never drive at unnecessarily high engine speeds even after the running-in period
is complete. The maximum permissible engine speed is marked by the start of the
red scale area of the revolutions counter. On vehicles fitted with a manual gear-
box, at the very latest shift up into the next gear when the red area is reached.
During acceleration (depressing the accelerator) exceptionally high engine
speeds are automatically reduced, yet the engine is not protected against too
high engine speeds which are caused by incorrectly shifting down the gears re-
sulting in a sudden increase of the engine speeds above the permitted maximum
revolutions which can lead to engine damage.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at an engine speed that is too low. Shift down a gear when the engine
is no longer running smoothly. Observe the recommended gear » page 10, Recom-
mended gear . CAUTION
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature. Never rev up a cold engine when the vehicle is
stationary or when driving in individual gears. For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear
as early as possible are ways to minimise fuel consumption and operating noise
levels and protects the environment. Ð New tyres
New tyres have to be “
run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so. Ð New brake pads
New brake pads initially do not provide full braking efficiency. The brake pads
must initially be “run in

”. Drive especially carefully for the first 200 km or so. Ð Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
The following guidelines must be observed: › Vehicles fitted with a petrol engine must always be refuelled with unleaded
petrol » page 105, Unleaded petrol;
› Do not pour too much oil into the engine
» page 111, Checking the engine oil
level ;
› Do not switch off the ignition while driving.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. £

Driving and the Environment

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

Avoid short distances
Fig. 93
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an above-average high fuel consumption. We therefore
recommend avoiding distances of less than 4
km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump-
tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 93 shows the different levels of fuel consumption after driving a certain
distance at a temperature of +20 °C and a temperature of -10 °C. Your vehicle has
a higher fuel consumption in the winter than in the summer. ÐChecking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. The rolling resistance will be
increased if the tyre filling pressure is too low. This will not only increase fuel con-
sumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold. ÐAvoid unnecessary ballast
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. It is worth checking
the luggage compartment to avoid transporting any unnecessary ballast. It is particularly in town traffic, when one is accelerating quite often, that the ve-
hicle weight will have a significant effect upon the fuel consumption. A rule of
thumb here is that an increase in weight of 100 kilograms will cause an increase
in fuel consumption of about 1 litre/100 kilometres.
At a speed of 100 - 120 km/h, your vehicle that is fitted with a roof rack cross
member without a load will use about 10

% more fuel than normal due to the in-
creased aerodynamic drag. Ð Saving electricity
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator. We therefore recommend switching off
electrical components if these are no longer required. Ð Environmental compatibility
Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new

ŠKODA. Particular emphasis has been placed
on the following points:
Design measures
› Joints designed to be easily detached.
› Simplified disassembly due to the modular structure system.
› Improved purity of different classes of materials.
› Identification of all plastic parts in accordance with VDA Recommendation 260.
› Reduced fuel consumption and exhaust emission CO
2.
› Minimum fuel leakage during accidents.
› Reduced noise.
Choice of materials › Extensive use of recyclable material.
› Air conditioning filled with CFC-free refrigerant.
› No cadmium.
› No asbestos.
› Reduction in the “vaporisation” of plastics.
Manufacture › Solvent-free cavity protection.
› Solvent-free protection of the vehicle for transportation from the production
plant to the customer. £
94 Driving Tips

Driving through water on the street
Fig. 94
Driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads):
› Therefore determine the depth of the water before driving through bodies of
water. The water level must fit around the strut on the side member as a maxi-
mum » Fig. 94;
› Do not drive any faster than at a walking speed. At a higher speed, a water
wave can form in front of the vehicle which can cause water to penetrate into
the air induction system of the engine or into other parts of the vehicle;
› Never stop in the water, do not reverse and do not switch the engine off;
› Deactivate the
START-STOP system before driving through water » page 65,
START/STOP. WARNING
■ Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance – risk of accident!
■ Avoid abrupt and sudden braking immediately after water crossings.
■ After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. Only apply the brakes for the pur-
pose of drying and cleaning the brake discs if the traffic conditions permit this.
Do not place any other road users in jeopardy. CAUTION
■ When driving through bodies of water, parts of the vehicle such as the engine,
gearbox, chassis or electrics can be severely damaged.
■ Oncoming vehicles can generate water waves which can exceed the permissible
water level for your vehicle. ■
Potholes, mud or rocks can be hidden under the water making it difficult or im-
possible to drive through the body of water. ■ Do not drive through salt water. The salt can lead to corrosion. Any vehicle parts
that have come into contact with salt water must be rinsed immediately with
fresh water. Note
After driving through a body of water, we recommend that the vehicle is checked
by a
ŠKODA specialist garage. Ð
96 Driving Tips

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

Inspecting and replenishing

Regular inspections of gas systems
First read and observe the introductory information and safety warn-
ings on page 106.
Every two years, the following inspections must be carried out:
› Check solenoid valves on the gas tanks for proper function.
› Check natural gas tank and lines for leaks and fixing, if necessary look for dam-
ages.
› Check the condition of fuel filler cap, filler tube and sealing ring, clean sealing
ring if necessary. ÐSafe natural gas
First read and observe the introductory information and safety warn-
ings on page 106.
The safety concept of the natural gas system ensures safe operation. It is equip-
ped with the following security features.
› At each natural gas tank, there is a solenoid valve that closes automatically af-
ter turning off the ignition or when running in petrol mode.
› A thermal fuse prevents uncontrolled rise in pressure in the natural gas tank in
case of fire.
› A flow limiter prevents sudden emptying of the natural gas tank in case the
pressure system is damaged.
› All the attachment points and materials are designed for maximum safety. ÐNatural gas quality and consumption
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is divided into quality groups H-gas and L-gas. The two types of gas
are subdivided according to their calorific value and nitrogen and carbon dioxide
contents. H-gas has a higher calorific value and lower nitrogen or carbon dioxide
content than L-gas.ä
ä
ä The higher the calorific value of natural gas, the lower is the consumption. How-
ever, the calorific value and the nitrogen and carbon dioxide contents can vary
within a quality group. Therefore, the consumption of the vehicle may even vary
when driving with only one natural gas quality (either only H-gas or L-gas).
The engine control of your vehicle automatically adjusts to the different natural
gas qualities. Therefore both natural gas qualities can be mixed in the fuel tank. It
is therefore not necessary to run the natural gas tank completely empty to fill up
another quality. Ð Engine compartment
