light SKODA CITIGO 2012 1.G Repair Manual

Note
■ Remove fresh stains such as those from ball-point pens, ink, lipstick, shoe pol-
ish, etc., from the material (leather), panels and textiles as quickly as possible. ■ Due to possible issues with the cleaning and care of the interior of your vehicle,
the special tools and knowledge required, we recommend that this is completed
by a
ŠKODA Service Partner. ÐWashing the vehicle
First read and observe the introductory information and safety warn-
ings on page 97.
The best protection for your vehicle against harmful environmental influences is
frequent washing and wax treatment. How often the vehicle should be washed
depends on a wide range of factors, such as:
›
Frequency of use;
› The parking situation (garage, below trees etc.);
› Season of the year;
› Weather conditions;
› Environmental influences.
The longer insect residues, bird droppings, tree sap, road and industrial dust, tar,
soot particles, road salt and other aggressive deposits remain adhering to the
paintwork of your vehicle, the more detrimental their destructive effect can be.
High temperatures, such as those caused by intensive sun's rays, accentuate this
caustic effect.
It is essential to also thoroughly clean the underside of the vehicle at the end of
the winter. ÐAutomatic car wash systems
First read and observe the introductory information and safety warn-
ings on page 97.
Your vehicle can be washed in automatic car wash systems.
The usual precautionary measures must be taken before washing the vehicle in
an automatic car wash system (closing the windows including the sliding/tilting
roof, etc.).ä
ä If your vehicle is fitted with any particular attached parts, such as a spoiler, roof
luggage rack, two-way radio aerial – it is best to consult the operator of the car
wash system beforehand.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system. Ð Washing by hand
First read and observe the introductory information and safety warn-
ings on page 97.
When washing by hand, first soften the dirt with plenty of water and rinse off as
much as possible.
Clean the vehicle with a soft
sponge, a washing glove or a washing brush. Work
from the top to the bottom – starting with the roof. Only apply slight pressure
when cleaning the vehicle's paintwork. Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such
areas.
Give the vehicle a good rinse after washing it and dry it off using a chamois leath-
er. Ð Washing with a high-pressure cleaner
First read and observe the introductory information and safety warn-
ings on page 97.
When washing the vehicle with a high-pressure cleaner, the instructions for use
of the equipment must be observed. This applies in particular to the
pressure
used and to the spraying distance. Maintain a sufficiently large distance to the
parking aid sensors and soft materials such as rubber hoses or insulation materi-
al. WARNING
Never use circular spray nozzles or dirt cutters! £

98 General Maintenance

CAUTION
The temperature of the water used for cleaning must not exceed 60 °C – risk of
damaging the vehicle. ÐPreserving and polishing the vehicle paintwork
First read and observe the introductory information and safety warn-
ings on page 97.
Preserving the vehicle paintwork
Good wax treatment is an effective way of protecting the paintwork from harmful
environmental influences.
The vehicle must be treated with a high-quality hard wax polish at the latest,
when no more drops form on the clean paintwork.
A new layer of a high-quality hard wax polish can be applied to the clean body-
work after it has dried thoroughly. Even if you use a wax preserver regularly we
still recommend that you treat the paintwork of the vehicle at least twice a year
with hard wax.
Polishing
Polishing is necessary if the vehicle's paintwork has become unattractive and if it
is no longer possible to achieve a gloss with wax preservatives.
If the polish does not contain any preserving elements, the paint must be treated
with a preservative afterwards. CAUTION
■ Never apply wax to the windows.
■ Mat painted or plastic parts must not be treated with polishing products or hard
waxes. ■ Do not polish the paintwork of the vehicle in a dusty environment, otherwise
the paintwork can be scratched. ÐChrome parts
First read and observe the introductory information and safety warn-
ings on page 97.ä
ä First clean the chrome parts with a damp cloth and then polish them with a soft,
dry cloth. If this method does not completely clean chrome parts, use a specific
chrome care product. CAUTION
Do not polish the chrome parts in a dusty environment, otherwise they can be
scratched. Ð Paint damage
First read and observe the introductory information and safety warn-
ings on page 97.
Slight damage to paintwork such as scratches, scuffs or traces of chip damage
must be treated immediately.
The ŠKODA Service Partners have a range of matching
touch-up pens or spray
cans available in the colour of your vehicle. Note
We recommend that any repairs to damaged paintwork are carried out by a
ŠKODA Service Partner. Ð Plastic parts
First read and observe the introductory information and safety warn-
ings on page 97.
Plastic parts can be cleaned using a damp cloth. If this does not prove to be ade-
quate, the parts can be treated with special solvent-free plastic cleaning prod-
ucts.
Paint care products are not suitable for plastic parts. Ð

Taking care of and cleaning the vehicle

De-icing windows and exterior mirrors
First read and observe the introductory information and safety warn-
ings on page 97.
Use a plastic ice scraper for removing snow and ice from the windows and mir-
rors. The ice scraper should not be moved forward and backward but in one direc-
tion to avoid any damage to the surface of the glass.
Clean the windows from the inside on a regular basis.
Dry the glass surfaces with a clean chamois leather or a cloth intended for this
purpose.
When drying the windows after washing the vehicle, do not use window leathers
that have been used to polish the bodywork. Residues of preservatives in the
window leather can dirty the window and reduce visibility. CAUTION
■ Never remove snow or ice from glass parts using warm or hot water – risk of
formation of cracks in the glass!
■ When removing snow or ice from windows and mirror lenses ensure that the
paintwork of the vehicle is not to damage.
■ Snow or ice that is contaminated with coarse dirt such as fine gravel, sand, and
salt must not be removed from the window glass and mirrors – risk of damage to
the surface of the windows and mirrors. ÐRadio reception
First read and observe the introductory information and safety warn-
ings on page 97.
Car parks, tunnels, tall buildings or mountains can disrupt the radio signal even
causing it to fail completely. ÐHeadlight lenses
First read and observe the introductory information and safety warn-
ings on page 97.
Use soap and clean water to clean the plastic headlight lenses.ä
ä
ä CAUTION
■ Never wipe the headlights dry and do not use any sharp objects to clean the
plastic lenses, this may damage the protective paintwork and consequently cause
the formation of cracks on the headlight lenses.
■ Do not use any aggressive cleaning or chemical solvent products to clean the
headlights – risk of damaging the headlight lenses. Ð Rubber seals
First read and observe the introductory information and safety warn-
ings on page 97.
The rubber seals on doors, the sliding roof and other windows remain smoother
and last longer if the seals are treated regularly with a suitable rubber care prod-
uct. This helps to prevent leakages and premature wear of the seals. Rubber
seals which are well cared for also do not stick together in cold winter weather.
Ð Door lock cylinders
First read and observe the introductory information and safety warn-
ings on page 97.
Specific products must be used for de-icing door lock cylinders.
Note
■ When washing your vehicle, ensure as little water as possible gets into the lock-
ing cylinders. ■ We recommend that suitable materials from ŠKODA Original Accessories are
used for maintaining the door lock cylinders. Ð

100 General Maintenance

Wheels
First read and observe the introductory information and safety warn-
ings on page 97.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular ba-
sis. Regularly remove salt and brake abrasion from the wheel rims otherwise the
material will be affected. Damage to the paint layer on the wheel rims must be
touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product for
light alloy wheels. Products which cause abrasion must not be used to treat the
wheel rims. WARNING
Water, ice and grit in the brake system can affect the braking efficiency – risk
of accident! CAUTION
Severe layers of dirt on the wheels can also result in wheel imbalance. This may
show itself in the form of a wheel vibration which is transmitted to the steering
wheel which, in certain circumstances, can cause premature wear of the steering.
This means it is necessary to remove the dirt. Note
We recommend that any repairs to damaged paintwork are carried out by a
ŠKODA Service Partner. ÐUnderbody protection
First read and observe the introductory information and safety warn-
ings on page 97.
The underside of your vehicle is protected for life against chemical and mechani-
cal influences.ä
ä As damage to the
protective layer when driving cannot be ruled out completely,
we recommend that you inspect the protective layer on the underside of your ve-
hicle and on the chassis at specific intervals – preferably at the beginning and end
of the winter.
ŠKODA Service Partners have suitable spray products and the necessary equip-
ment available, and are familiar with the instructions for use. We therefore rec-
ommend that touch-up work or additional corrosion protection measures are car-
ried out by a ŠKODA Service Partner. WARNING
Never use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters or heat shields. When the engine reaches its
operating temperature, these substances might ignite – risk of fire! Ð Protection of hollow spaces
First read and observe the introductory information and safety warn-
ings on page 97.
All the cavities of your vehicle which are at risk from corrosion are protected for
life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. If any small
amount of wax flow out of the cavities at high temperatures, these must be re-
moved with a plastic scraper and the stains cleaned using a petroleum cleaner. WARNING
Safety regulations should be observed when using petroleum cleaner to re-
move wax – risk of fire! Ð Artificial leather and materials
First read and observe the introductory information and safety warn-
ings on page 97.
The artificial leather can be cleaned using a damp cloth. If this does not prove to
be adequate, these parts can only be treated with special
solvent-free plastic
cleaning and care products . £

101
Taking care of and cleaning the vehicle

Clean upholstery cover materials and cloth trims on doors, luggage compartment
cover, etc. using specific cleaning agents, e.g., dry foam. Use a soft sponge, brush,
or commercially available microfibre cloth. Use a cloth and a specific cleaning
agent to clean the roof trim.
Some clothing materials, such as dark denim, do, in part, not have sufficient col-
our fastness. This can cause damage or clearly visible discolouration to seat cov-
ers (fabric or leather) even when used correctly. This particularly applies to light
seat covers (fabric or leather). This is not a defect in the seat cover, but poor col-
our fastness of the clothing textiles. ÐFabric covers on electrically heated seats
First read and observe the introductory information and safety warn-
ings on page 97.
Do not clean the seat covers
using moisture as this can damage the seat heating
system.
Use a specific cleaning agent such as dry foam or similar to clean the covers. ÐNatural leather
First read and observe the introductory information and safety warn-
ings on page 97.
Depending on the amount of wear-and-tear, the leather should be cleaned on a
regular basis.
Normal cleaning
Clean soiled areas of the leather with slightly moistened cotton or woollen cloth.
Severe soiling
Ensure that the leather is not soaked through at any point and that no water gets
into the stitching of the seams.
Dry off the leather with a soft, dry cloth.
Removing stains
Remove fresh water-based stains (e.g., coffee, tea, juices, blood) with an absorb-
ent cloth or household cleaning paper. A specific cleaning agent is required for
dried-on stains.
ä
ä
Remove fresh
grease-based stains (e.g. butter, mayonnaise, chocolate, etc.) with
an absorbent cloth, household cleaning paper, or use a suitable cleaner if the
stain has not yet penetrated into the surface.
Use a grease solvent for grease stains which have dried in.
Remove specific stains (e.g. ball-point pens, marker pen, nail varnish, dispersion
paint, shoe polish, etc.) with a special stain remover suitable for leather.
Leather care
Treat the leather roughly every six months with a suitable leather care product.
Apply only a small amount of the cleaning and care product.
Dry off the leather with a soft, dry cloth. CAUTION
■ Avoid leaving the vehicle for lengthy periods in bright sunlight to avoid the
leather from bleaching. If the vehicle is parked in the open for lengthy periods,
protect the leather from direct sunlight by covering it.
■ Sharp-edged objects on items of clothing such as zip fasteners, rivets, sharp-
edged belts, jewellery and pendants may leave permanent scratches or signs of
rubbing on the surface.
■ The use of a mechanical steering wheel lock may damage the leather surface of
the steering wheel. Note
■ Use a care cream with light blocker and impregnation effect on a regular basis
and each time after cleaning. The cream nourishes the leather, allows it to
breathe and keeps it supple and also provides moisture. It also creates surface
protection. ■ Clean the leather every 2 to 3 months, remove any fresh stains as they occur.
■ Also look after the leather dye. Refresh any areas with a special coloured leath-
er cream as required.
■ The leather is a natural material with specific properties. During the use of the
vehicle, minor optical changes can occur on the leather parts of the covers (e. g
wrinkles or creases as a result of the stress of the covers). Ð
102 General Maintenance

Unleaded petrol
First read and observe the introductory information and safety warn-
ings on page 104.
Your vehicle can only be operated with
unleaded fuel that complies with the
standard EN 228 (in Germany: standard DIN 51626-1 or E10 for unleaded fuel with
an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel
with the octane rating 95 RON and 98 RON).
Prescribed fuel – unleaded fuel 95/91 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol 91 RON can al-
so be used but results in a slight loss in performance.
If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible.
Prescribed fuel – unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available. The journey must only be
continued at medium engine speeds and a minimum engine load. Driving at high
engine revs or a high engine load can severely damage the engine! Refuel using
petrol of the prescribed octane number as soon as possible.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Unleaded petrol with higher octane number
Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power in-
crease or a lower fuel consumption.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption. ä
Prescribed fuel – unleaded petrol 98/(95) RON
Use unleaded fuel with the octane rating
98 RON. Unleaded petrol 95 RON can
also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98 RON or 95 RON is not available. The journey
must only be continued at medium engine speeds and a minimum engine load.
Driving at high engine revs or a high engine load can severely damage the engine!
Refuel using petrol of the prescribed octane number as soon as possible.
Even in the event of an emergency, petrol of a lower octane number than 91 RON
must not be used, otherwise the engine can be severely damaged!
Fuel additives
Only use unleaded petrol, which complies with the standard EN

228 (in Germany:
standard DIN 51626-1 or E10 for unleaded fuel with an octane rating of 95 RON
and 91 RON or DIN 51626-2 or E5 for unleaded fuel with an octane rating of
95 RON and 98 RON), as these meet all of the requirements for fault-free engine
operation. We therefore recommend that no fuel additives are used. CAUTION
■ All
ŠKODA vehicles with petrol engines must only be operated with unleaded
petrol. Just filling the tank with leaded petrol once will damage the exhaust sys-
tem!
■ Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.
■ In no case may fuel additives with metal components be used, especially not
with manganese and iron content.
LRP (lead replacement petrol) fuels with met-
allic components may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system!
■ Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or exhaust system!
■ The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system. Ð

Inspecting and replenishing

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

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.

■ 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

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. £
