Checking the coolant level
Fig. 143
Engine compartment: Coolant
expansion reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of coolant in the coolant expansion bottle
» Fig. 143. 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 20, 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
ä Replenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 169.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 143 on
page 174 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 A
(max.)
» Fig. 143 on page 174! 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. Ð

174 General Maintenance

Radiator fan
First read and observe the introductory information and safety warn-
ings on page 169.
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.
ÐChecking the brake fluid
Fig. 144
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of brake fluid in the reservoir
» Fig. 144. 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 19, Brake system .
ä
ä 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 Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 169.
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. Ð

Inspecting and replenishing

Windscreen washer system
Fig. 145
Engine compartment: Wind-
screen washer fluid reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
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 filling level of the container is about 3
litres and about 5.5 litres on vehicles
that have a headlight washing system 1)
.
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.
ä 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

Vehicle battery: Electrolyte level
indicator
ä
First read and observe the introductory information and safety warn-
ings on page 176.
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 179.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 147, 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 Operation in winter
First read and observe the introductory information and safety warn-
ings on page 176.
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

178 General Maintenance

Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
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”.
“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 198, Jump-starting in vehicles with the

START-STOP
system . Ð
ä Disconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.

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 176.
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
