Brake fluid changeFirst 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 sys-
tem.
The water content lowers the boiling point of the brake fluid.
The brake fluid must comply with the following standards or specifications: › VW 50114;
› FMVSS 116 DOT4.
WARNINGDo 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 replaced as part of a proscribed Inspection service carried out by
a ŠKODA Partner.
Windscreen washer system
Fig. 152
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 is located in the engine compartment and
contains the cleaning fluid for the windscreen or rear window and for the head-
light cleaning system.
The capacity of the reservoir is about 3 litres or about 4.7 litres on vehicles that
have a headlight cleaning system.
Clear water is not sufficient to intensively clean the windscreen and headlights.
We recommend using clean washing water together with the screen cleaner from
the range of ŠKODA Original Accessories (in winter additionally with antifreeze)
which is capable of removing stubborn dirt.
In Winter, the washing water should always be mixed with antifreeze even if the
vehicle has 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.
■
Do not remove the filter from the windscreen washer fluid reservoir when re-
plenishing it with liquid otherwise the liquid transportation system can be conta-
minated, which can cause the windscreen washer system to malfunction.

Warning symbols on the vehicle battery
SymbolDescriptionAlways wear eye protection!Battery acid is severely caustic. Always wear gloves and eye protec-tion!Keep fire, sparks, open flames and lit cigarettes well clear of the ve-
hicle battery!When charging the vehicle battery, a highly explosive gas mixture is produced!Keep children away from the vehicle battery!
Improper handling of the battery can lead to damage occurring. We recommend
having all work on the vehicle battery be undertaken by a ŠKODA Partner.
WARNINGThere is a risk of injuries, poisoning, chemical burns, explosions or fire when
carrying out any work on the battery and on the electrical system. It is essen-
tial to comply with the warning instructions stated below and with the gener-
al applicable rules of safety.■
Keep children away from the vehicle battery.
■
The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care.
■
Always wear protective gloves, eye and skin protection when handling the
vehicle battery.
■
Corrosive fumes in the air irritate the air passages and lead to conjunctivitis
and inflammation of the air passages in the lungs.
■
Battery acid corrodes dental enamel and creates deep wounds after contact
with the skin which take a long time to heal. Repeated contact with diluted
acids causes skin diseases (inflammations, ulcers, skin cracks).
■
Acids coming into contact with water are diluted accompanied by significant
development of heat.
WARNING (Continued)■ Do not tilt the battery otherwise battery electrolyte may flow out of the bat-
tery vent openings. Protect the eyes with safety glasses or a shield! There is
the danger of suffering blindness!■
If any battery electrolyte comes into contact with your eyes, rinse the rele-
vant eye immediately with clear water for several minutes - consult a doctor
immediately!
■
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If you swallow
battery acid, seek immediate medical assistance!
■
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 a metal object,
cable) creates a short circuit - risk of melting of lead struts, explosion and
burning of the battery, jets of acid spurting out.
■
It is prohibited to work with a naked flame and light.
■
Smoking or to carrying out any activities which produce sparks are prohibi-
ted.
■
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 engine,
the ignition and all of the electrical components and disconnect the negative
terminal (-) on the battery.
■
The relevant lamp must always be switched off before a light bulb is re-
placed.
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
caustic burns!
■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with an electrolyte level that is too low –
risk of explosion and caustic burns.
■
Never use a damaged vehicle battery – risk of explosion! Replace any vehicle
battery that is damaged. 
177Inspecting and replenishing

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, followed by the positive terminal
(+).■
When connecting the battery to the electrical system, first of all connect the
positive terminal (+) of the battery, followed by the negative terminal (-). Under no
circumstances 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.

Checking the battery electrolyte levelFig. 154
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 176.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called magic eye » Fig. 154, 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.
For technical reasons, on vehicles with the description “AGM”, the electrolyte lev- el 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.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, 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 ŠKODA Partner before the start of the winter.
NoteThe battery electrolyte level is periodically checked by a ŠKODA Partner as part of
the Inspection Service.
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 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 thedevice.
›
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.
Replacing the vehicle battery
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 Partner.
We recommend that the battery is replaced by a ŠKODA Partner, where the new
vehicle battery will be installed properly and the original battery will be disposed
of in accordance with national regulations. 
179Inspecting and replenishing

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 196, Jump-starting in vehicles with the START-STOP
system .
Note
We recommend having the quick charging of vehicle batteries undertaken by a
ŠKODA specialist garage.
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 functionsare initially deactivated or are no longer able to operate fault-free:

ber» operating instructions for Info-
tainment radio or » operating in-
structions for Infotainment Navi-
gationSetting the clock» page 11Data in the multifunction display are deleted» page 22
Note
We recommend having the vehicle checked by a ŠKODA Partner to ensure the full
functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 176.
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.
