check engine SKODA SUPERB 2012 2.G / (B6/3T) Owner's Guide

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 indicator light in the instrument cluster will indicate whether the oil level is
too low » page 22, Engine oil level . In this case, check the oil level with the dip-
stick, as soon as possible. Add oil accordingly. CAUTION
■ The oil level must on no account extend beyond the range A
» Fig. 158
. Risk of
damaging the exhaust system!
■  Do not continue your journey if for some reason it is not possible to top up
the engine oil under the prevailing conditions! Switch off the engine and obtain
professional assistance from a
ŠKODA specialist garage, otherwise it could cause
severe engine damage. Note

› Replenish the oil in portions of 0.5 litres in accordance with the correct specifi-
cations » page 219, Specification and engine oil capacity .
› Check the oil level
» page 178.
› Carefully screw on the oil filler opening cap and push the dipstick in fully. ÐChanging engine oil
First read and observe the introductory information and safety warn-
ings on page 176.ä
ä 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. Ð Coolant
First read and observe the introductory information and safety warn-
ings on page 176.
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. 159 on page 180. £

■ 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! Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventila-
tion), the coolant capacity is approx. 1 l larger. ÐChecking the coolant level
Fig. 159
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 176.
ä The coolant expansion bottle is located in the engine compartment.
› Switch off the engine.
› Open the bonnet
» page 177.
› Check the level of coolant in the coolant expansion bottle.
» Fig. 159. The cool-
ant level when the engine is cold must lie between the B
(MIN) and A
(MAX)
markings. The level may also rise slightly above the A
(MAX) marking when the
engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the indicator light  lighting up in the instrument cluster » page 21, Coolant tem-
perature/coolant level . We still recommend inspecting the coolant level directly
at the reservoir from time to time.
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. Ð Replenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 176.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 159 on
page 180
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. £
ä
180 General Maintenance

Do not fill the coolant above the mark A
(max.)
» Fig. 159 on page 180! Excess
coolant heats up and then is forced out of the cooling system through the pres-
sure 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. 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. ÐRadiator fan
First read and observe the introductory information and safety warn-
ings on page 176.
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
ä Checking the brake fluid
Fig. 160
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 176.
The brake fluid reservoir is located in the engine compartment.
› Switch off the engine.
› Open the bonnet
» page 177.
› Check the level of brake fluid in the reservoir
» Fig. 160. 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.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking. If
the brake fluid level is too low, this is indicated by the indicator light  lighting
up in the instrument cluster » page 20, Brake system . WARNING
If the fluid level has dropped below the MIN marking,  do not continue your
journey - risk of accident! Seek help from a
ŠKODA specialist garage.Ð
ä
181
Inspecting and replenishing

Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 176.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment. Excessive water in the brake fluid may be the cause of corrosion in
the brake system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with the following standards or specifications:
› VW 50114;
› FMVSS 116 DOT4. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. ÐWindscreen washer system
Fig. 161
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn-
ings on page 176.ä
ä
The windscreen washer fluid reservoir contains the cleaning fluid for the wind-
screen or rear window and for the headlight cleaning system. The windscreen
washer fluid reservoir is located in the engine compartment.
The capacity of the reservoir is about 3 litres or about 5.5
litres on vehicles that
have a headlight cleaning system.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We therefore recommend using clean water with a screen cleaner (including anti-
freeze in the winter) that is able to remove stubborn dirt.
Antifreeze should always be added to the cleaning water in the winter even if the
vehicle is fitted with heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. The freeze protection at this concentration is sufficient
only to -5 °C. CAUTION
■ Under no circumstances must radiator antifreeze or other additives be added to
the windscreen washer fluid.
■ If the vehicle is fitted with a headlight cleaning system, only cleaning products
which do not attack the polycarbonate coating of the headlights must be added
to the windscreen washer fluid. Note
Do not remove the filter from the windscreen washer fluid reservoir when replen-
ishing it with liquid otherwise the liquid transportation system can be contamina-
ted, which can cause the windscreen washer system to malfunction. Ð Vehicle battery

Checking the battery electrolyte level
Fig. 163
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 182.
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 185.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 163, 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
ä Operation in winter
First read and observe the introductory information and safety warn-
ings on page 182.
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.
Ð Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.
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”. £

Inspecting and replenishing

“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 204, Jump-starting in vehicles with the

START-STOP
system . ÐDisconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.

Data in the multifunction display are deleted. » page 12Note
We recommend having the vehicle checked by a ŠKODA Service Partner to ensure
the full functionality of all electrical systems. ÐReplacing the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.ä
ä 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.
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. Ð Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 182.
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. Ð ä

■ During inflation, the tyre inflation hose and air compressor may get hot- risk
of injury! ■ Do not place the hot tyre inflation hose or hot air compressor on flammable
materials - risk of fire!
■ If you cannot inflate the tyre to at least 2.0 bar, this means the damage sus-
tained was too serious. The sealing agent cannot be used to seal the tyre. Do
not drive the vehicle. Get professional assistance! CAUTION
Switch off the air compressor after running 8 minutes at the latest - danger of
overheating! Allow the air compressor to cool a few minutes before switching it
on again. Ð Check after driving for 10 minutes

system.
■ Have the electrical system checked as quickly as possible by a ŠKODA specialist
garage if a newly inserted fuse blows again after a short time.
■ When unlocking and locking the cover for the fuse box in the engine compart-
ment, it must be pressed on the sides of the box, otherwise the locking mecha-
nism can be damaged. ■ The cover for the fuse box in the engine compartment must always be applied
correctly. Water can penetrate and cause damage to the vehicle if the cover was
not applied correctly! Note
■ We recommend always carrying replacement fuses in the vehicle. A box of re-
placement fuses can be purchased from
ŠKODA Original Accessories.
■ Multiple fuses may exist for a single power consuming device.
■ Multiple power consuming devices can share a single fuse.
■ Electrically adjustable seats are protected by automatic circuit breakers, which
switch on again automatically after a few seconds after the overload has been
eliminated. Ð

Fuses and light bulbs

›
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 boot. 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 176, Engine compartment .
■ Bulbs H7 and H3 are pressurised and may burst when changing the bulb -
risk of injury! We therefore recommended wearing gloves and safety glasses
when changing a bulb. ■ Gas discharge bulbs (xenon bulbs) operate with a high voltage, professional
knowledge is required - danger to life! 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 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
