WARNING (Continued)■If coolant is swallowed, consult a doctor immediately.■Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■If for some reason it is not possible to top up the coolant under the current
circumstances,  do not continue driving! Switch off the engine and seek as-
sistance from a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage, 
do not continue driving! Switch off the en-
gine and seek assistance from a specialist garage.
■
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 protec-
tion and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 188 on page 198 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.

in the instrument cluster as well as the relevant notification » page 41. We still
recommend inspecting the coolant level directly at the expansion tank from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 197 first.
The coolant expansion tank must always contain a small amount of cool-
ant » page 198, in section Introduction .

Checking the brake fluid level
199
Specification
199
The brake fluid reservoir is located in the engine compartment » Fig. 189 on
page 199 .
WARNING■
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 192.■
Do not use used brake fluid - the function of the brake system may be im-
paired – risk of accident!
CAUTION
■ Do not continue your journey if the fluid level has dropped below the “MIN”
marking » Fig. 189 on page 199 ,  do not continue driving - there is a risk of
an accident! Seek help from a specialist garage.■
Brake fluid damages the paintwork of the vehicle.
Note
■ The brake fluid is changed as part of a prescribed inspection services.■We recommend using brake fluids from the ŠKODA Original Accessories
range.Checking the brake fluid levelFig. 189
Brake fluid reservoir
Read and observe and on page 199 first.
The fluid can be checked if the following conditions are met.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The bonnet is open.
Checking the level
›
Check the level of brake fluid in the reservoir » Fig. 189.
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
level drops significantly within a short time or if it drops below the “MIN” mark-
ing.
Too low brake fluid level is indicated by the warning light  being shown on
the display of the instrument cluster as well as the corresponding mes-
sage » page 35 .
Specification
Read and observe
and on page 199 first.
The brake fluid must comply with the following standards or specifications:› VW 50114;
› FMVSS 116 DOT4.
199Inspecting and replenishing

■Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.■
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
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.
Opening the cover
Fig. 190
Polyester cover of vehicle bat-
tery
Read and observe and on page 200 first.
The battery is located in the engine compartment. For some equipment var-
iants, it is located underneath a polyester cover » Fig. 190.
›
Fold out the cover on the battery in the direction of the arrow.
The battery cover is installed in reverse order.
Checking the battery electrolyte levelFig. 191
Vehicle battery: Electrolyte level
indicator
Read and observe and on page 200 first.
On vehicles with a vehicle battery fitted with a colour indicator » Fig. 191, the
electrolyte level can be determined by looking at the change in colour of this
display.
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
garage, 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 tem-
peratures. 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,
recharged by a specialist garage before the start of the winter. 
201Inspecting and replenishing

Note■The battery acid level is also checked regularly by a specialist garage as part
of the inspection service.■
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Charging
Read and observe
and on page 200 first.
A properly charged vehicle battery is essential for reliably starting the engine.
A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, 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 the
mains 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”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, 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 low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical components and disconnect the negative
terminal 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), do not connect the pole terminal of the charger directly to the negative
terminal of the vehicle battery, but rather only to the engine earth » page 220,
Jump-starting using the battery from another vehicle .
Replacing
Read and observe
and on page 200 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. 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
disposed of in accordance with national regulations.
Disconnecting and reconnecting

CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 200 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the bettery is subjected to heavy loads. 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 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
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 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
driver is not aware of it having taken place.203Inspecting and replenishing

Some manual skills are required to change a bulb. For this reason, we recom-
mend 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 compart-
ment.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 192.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty 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, professio-
nal knowledge is required – risk of death!
■
Switch off the respective vehicle light when changing the 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,
napkin, or similar.Note■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible 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 ve-
hicle. Replacement bulbs can be purchased from ŠKODAOriginal Accessories.
■
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the main beam, low beam or fog lights.
