ignition SKODA CITIGO 2012 1.G Service Manual

CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the electrical system, first of all dis-
connect the negative terminal
(-) of the battery. Then disconnect the positive ter-
minal (+).
■ When connecting the battery to the electrical system, first connect the positive
terminal (+) of the battery. Then connect the negative terminal
(-). Under no cir-
cumstances must the battery cables be connected incorrectly – risk of a cable fire.
■ Ensure that battery acid does not come into contact with the bodywork – risk of
damage to the paintwork.
■ Do not place the battery in direct daylight in order to protect the vehicle battery
housing from the effects of ultra-violet light.
■ If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e.
g.
control units) also in idle state. Prevent the battery from discharging by discon-
necting the battery's negative terminal or continuously charging the battery with
a very low charging current.
■ If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge. For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations. Note
You should replace batteries older than 5 years. Ð Checking the battery electrolyte level
Fig. 104
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 115.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 117.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 104 , the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour – electrolyte level is correct.
› Colourless or light yellow colour – electrolyte level too low, the battery must be
replaced. Note
■ The battery electrolyte level is periodically checked by a
ŠKODA Service Partner
as part of the Inspection Service. ■ For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked. ■ Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start. Ð

116 General Maintenance

Operation in winter
First read and observe the introductory information and safety warn-
ings on page 115.
At low temperatures, the vehicle battery only has part of the initial power output
that it has at normal temperatures.
A discharged vehicle battery may already freeze at temperatures just below 0
°C.
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a ŠKODA Service Partner before the start of the winter.
ÐCharging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 115.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
› Only for “quick-charging”: Disconnect both battery cables (first of all “negative”,
then “positive”).
› Attach the terminal clamps of the charger to the battery terminals (red =
“posi-
tive
”, black = “negative”).
› Only now plug the mains cable of the charger into the power socket and switch
on the device.
› When charging is completed: Switch off the charger and remove the mains ca-
ble from the power socket.
› Only then disconnect the charger's terminal clamps.
› Reconnect the cables to the battery, if necessary (first of all
“positive”, then
“negative
”).
It is not normally necessary to disconnect the cables of the battery if you re-
charge the vehicle battery using low amperages (as for example from a mini-
charger). Refer to the instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called “ quick-charging”.
ä
ä “Quick-charging” the vehicle battery is
dangerous
and requires a special charger
and specialist knowledge. We therefore recommend having the quick charging of
vehicle batteries undertaken by a ŠKODA specialist garage.
The vent plugs of the vehicle battery should not be opened for charging. CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 136, Jump-starting in vehicles with the

START-STOP
system . Ð Disconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 115.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free:
Operation Operating measure
Enter radio code number » Radio manual
Setting the clock » page 12
Data in the multifunction display are deleted. » page 11 Note
We recommend having the vehicle checked by a ŠKODA Service Partner to ensure
the full functionality of all electrical systems. Ð Replacing the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 115.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable types of vehicle batteries can
be purchased from a

ŠKODA Service Partner. £

117
Inspecting and replenishing

We recommend that the battery is replaced by a ŠKODA Service Partner, where
the new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.
ÐAutomatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 115.
An intelligent vehicle power management system automatically takes various
measures at high loads on the vehicle battery to prevent discharging of the bat-
tery: This manifests itself by the following:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large consumers of power, e.g. seat heaters, rear window
heaters, voltage supply to the 12V power socket, have their power limited or in
case of emergency shut off completely. Note
Despite such intervention by the vehicle electric system management, the vehicle
battery may be drained. For example, when the ignition is switched on a long time
with the engine turned off or the side or parking lights are turned on during lon-
ger parking. Driving comfort is not put at risk by any shutting off of consumers.
Often the driver is not aware of it having taken place. Ðä
118 General Maintenance

WARNING
■ A discharged vehicle battery may already freeze at temperatures just below
0 °C. In case of frozen battery carry out no jump-starting – risk of explosion!
■ Pay attention to the warning instructions relating to working in the engine
compartment » page 108, Engine compartment .
■ The non-insulated parts of the terminal clamps must never make contact
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing parts of the vehicle – risk of short circuit! ■ Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started. ■ Route the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment. ■ Do not bend over the battery – risk of caustic burns!
■ The vent screws of the battery cells must be tightened firmly.
■ Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery – risk of an explosion!
■ Never jump-start vehicle batteries with an electrolyte level that is too low –
risk of explosion and caustic burns. 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. ■ We recommend you buy jump-start cables from a car battery specialist. Ð Jump-starting

engine block, or to the engine block itself.
Starting engine
› Start the engine on the vehicle providing the power and allow it to idle.
› Now start the engine of the vehicle with the discharged battery.
› If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for about 30 seconds before repeating the process.
› Disconnect the cables in exactly the
reverse order to the one described above. Ð

ä
Introduction
This chapter contains information on the following subjects:
Front towing eye 137
Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automated transmission can be towed with a tow bar or a tow rope
or with the front wheels raised. If the vehicle is raised at rear, the automatic gear-
box is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
When towing, the following guidelines must be observed.
Driver of the tow vehicle
› Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automated transmission.
ä
›
On vehicles with a manual transmission, only push down on the accelerator
pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
› Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can
be switched on.
› Take the vehicle out of gear or move the selector lever into position
N if the
vehicle is fitted with an automated transmission.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught. CAUTION
■ Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. The bat-
tery from another vehicle can be used as a jump-start aid » page 134, Jump-start-
ing .
■ If the gearbox of your vehicle no longer contains any oil because of a defect,
your vehicle must only be towed in with the driven wheels raised clear of the
ground, or on a special vehicle transporter or trailer.
■ The vehicle must be transported on a special vehicle or trailer if it is not possible
to tow in the vehicle in the way described or if the towing distance is greater than
50 km. ■ To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■ One should be constantly vigilant not to allow impermissibly high towing forces
or jerky loadings. There is always a risk of excessive stresses and damage result-
ing at the points to which you attach the tow rope or tow bar when you attempt
to tow a vehicle which is not standing on a paved road.
■ Attach the tow rope or the tow bar only to the towing eye » page 137. £

Introduction
This chapter contains information on the following subjects:
Headlights 141
Changing the light bulb for side repeater turn signal lights 142
Changing light bulbs for fog lights 142
Changing the bulb for the licence plate light 143
Tail lamp assembly 143
Some manual skills are required to change a bulb. For this reason, if uncertain, we
recommend that bulbs are replaced by a ŠKODA specialist garage or other expert
help is sought.
› Switch off the ignition and all of the lights before replacing a bulb.
› Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
› A stowage compartment for replacement bulbs is located in a plastic box in the
spare wheel or underneath the floor covering in the luggage compartment. WARNING
■ Accidents can be caused if the road in front of the vehicle is not sufficiently
illuminated and the vehicle cannot or can only be seen with difficulty by other
road users.
■ Always read and observe the warnings before completing any work in the
engine compartment » page 108, Engine compartment .
■ The H4 bulb is under pressure and may explode during a lamp replacement -
risk of injury! We therefore recommended wearing gloves and safety glasses
when changing a bulb. CAUTION
■ Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth, nap-
kin, or similar. ■ When removing and installing the number plate light and tail light make sure
that the paintwork of the vehicle and the tail light are not damaged. Note
■ This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other
light bulbs should be changed by a

ŠKODA specialist garage.
■ We recommend that a box of replacement bulbs be always carried in the vehi-
cle. Replacement bulbs can be purchased from
ŠKODAOriginal Accessories.
■ We recommend that the headlight settings are checked by a ŠKODA specialist
garage after replacing a bulb in the main or low beam.
■ LED diodes should be changed by a specialist ŠKODA garage. Ð Headlights
