The coolant consists of water with a concentration of coolant additive. This mix-
ture guarantees antifreeze protection, protects the cooling/heater system
against corrosion and prevents the formation of scale.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries the concentration of coolant additive should be at least 40 %.
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 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to a maximum of 60 % (antifreeze
protection down to approx. -40 °C).
When refilling, only use antifreeze with the name specified on the coolant expan-
sion tank » Fig. 185 on page 222.WARNING■
The engine compartment of your car is a hazardous area. While working in
the engine compartment, be sure to observe the following warn- ings » page 215 .■
Do not continue your journey, if for some reason it is not possible to top
up the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The amount of coolant additive in the coolant must never be allowed to be less
than 40 %.■
Over 60 % of coolant additive in the coolant reduces the antifreeze protection
and coolant effectiveness.
■
A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 185 on page 222.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

This chapter contains information on the following subjects:
Checking the brake fluid level
223
Changing
223WARNING■ The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 215.■
If the fluid level has dropped below the MIN marking » Fig. 186 on page 223,
 do not continue your journey - risk of accident! Seek help from a specialist
garage.
■
Do not use used brake fluid - the function of the brake system may be im-
paired – risk of accident!
CAUTION
Brake fluid damages the paintwork of the vehicle.
Note
The brake fluid is changed as part of a prescribed inspection services.
Checking the brake fluid levelFig. 186
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 223.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of brake fluid in the reservoir » Fig. 186.
The level must be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the brake pads.
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  » page 16 , 
Brake system lighting up in the instrument cluster.

on page 223.
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 sys-
tem.
The water content lowers the boiling point of the brake fluid. 

Checking the battery electrolyte levelFig. 188
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 224.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 188, 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.
Vehicles with a START-STOP system are fitted with a battery control unit for checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist ga-
rage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
Winter time
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
CAUTIONFor technical reasons, on vehicles with the description “AGM”, the electrolyte lev- el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
First read and observe the introductory information and safety warn-ings
on page 224.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a “quick-charge”, 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”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove themains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not necessary to disconnect the cables of the battery if you recharge the ve- hicle battery using low amperages (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 necessary to disconnect both cables before charging the battery with high
amperages, so-called “ quick-charging”.
The vent plugs of the vehicle battery should not be opened for charging. 
226General Maintenance

WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
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 244, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 224.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be
purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.

Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 224.
On disconnecting and reconnecting the vehicle battery, the following functions
are initially deactivated or are no longer able to operate fault-free:

NavigationSetting the clock» page 14Data in the multifunction display are deleted» page 29
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 224.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the bettery is subjected to heavy loads. This manifests itself by the fol-
lowing.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle 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 longer parking.■
Consumers which are supplied via a 12 V socket can cause the vehicle battery to
discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the driv-
er is not aware of it having taken place.

Some manual skills are required to change a bulb. For this reason, we recommend
having bulbs replaced by a specialist garage or seeking other expert help in the
event of any uncertainties.
› 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■ Always read and observe the warnings before completing any work in the
engine compartment » page 215.■
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.
■
Bulbs H7 H8 and H15 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 – risk of death!
■
The relevant lamp must always be switched off before a light bulb is re-
placed.
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, napkin, or sim-
ilar.
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 bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the vehi-
cle. Replacement bulbs can be purchased from ŠKODAOriginal Accessories.
■
We recommend having the headlight settings checked by a specialist garage af-
ter replacing a bulb in the main beam, low beam or fog lights.
