•If the fluid level has dropped below the MIN marking, do not
drive any further - risk of accident! Contact a Škoda dealer to obtain
professional assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture
from the surrounding air over a period of time. 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. This is why brake
fluid must be replaced every two years.
One may only use new genuine brake fluid from Škoda Auto a.s. The
specification for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda
Service Partner as part of an Inspection Service.
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.
•Brake fluid is toxic! It must therefore be kept safely in closed
original containers and well away from children and unauthorized
persons.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with proper disposal of brake fluid, the
special tools and the professional knowledge required, you should have
the brake fluid replaced by a Škoda Service Partner.

Taking off cover
– Press the cover in direction of arrow ⇒fig. 178.
There is a risk of injuries, scalding, accidents and burns when carrying out
any work on the battery and on the electrical system. For this reason, it is
essential to comply with the warning instructions ⇒ stated below and
with the general applicable rules of safety.
WARNING
•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 batteries. 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, slin
cracks). Acids coming into contact with water are diluted accompa-
nied by significant development of heat.
•Do not tilt the battery otherwise battery electrolyte may flow out
of the battery vent openings. Protect the eyes with safety glasses
or a shield! There is the danger of suffering blindness! If any
battery electrolyte gets into your eye, rinse out your eye immedi-
ately with clear water for several minutes. Contact a doctor without
delay.
•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. Contact a doctor immediately if you swallow battery elec-
trolyte.
•Keep batteries out of the reach of children.
•Hydrogen is released when you charge a battery and a highly
explosive gas mixture is produced. An explosion can be caused through sparkling over during unclamping or loosening of the
cable plug while the ignition is on.
•Bridging of the poles
will create a short circuit (e.g. through
metal objects, cables). Possible consequences of a short circuit:
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, to smoke or
to carry out any activities which produce sparks. 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 as well as all electrical components and
disconnect the negative cable (-) on the battery. If you wish to
replace a bulb it is sufficient to switch off the appropriate light.
•Never charge a frozen or thawed battery - risk of explosion and
caustic burns! Replace a frozen battery.
•Never use a battery which is damaged - risk of explosion! Imme-
diately replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched off,
otherwise the electrical system (electronic components) of the vehicle
may be damaged. When disconnecting the battery from the electrical
system of the vehicle, first disconnect the negative terminal (-) of the
battery. Then disconnect the positive terminal (+).
•When reconnecting the battery, first connect the positive terminal (+)
and only then the negative terminal (-) of the battery. You must on no
account connect the cables wrongly - risk of a cable fire!
•Ensure that battery acid does not come into contact with the vehicle
body otherwise damage could occur to the paintwork.

•Do not place the battery in direct daylight in order to protect the battery
housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the envi-
ronment - contact your specialist garage regarding disposing of the
battery.
Note
Please also refer to the guidelines ⇒page 233, “Disconnecting and
reconnecting the battery”, also after connecting the battery.
Battery with a charge level indicator, the so-called
magic eye
There is a so-called magic eye ⇒fig. 179 located on the top of the battery.
The “magic eye” changes its colour in line with the charge state of and
electrolyte level in the battery.
Air bubbles can influence the colour of the “magic eye”. For this reason
carefully knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour. Have the battery checked by a specialist
garage.
Batteries, which are more than 5 years old, must be replaced. We recom-
mend you have the electrolyte level inspected and adjusted to the correct
level or the battery replaced if necessary by a specialist garage.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery
will discharge because certain electrical components consume electricity
(e.g. control units) also in idle state. You can prevent the discharging of
the battery by disconnecting the negative terminal or charging the battery
constantly with a very low charging current. Please also refer to the notes
when working on the battery ⇒page 228, “Working on the battery”.
Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating
conditions. We do, however, recommend that you have the electrolyte
level inspected from time to time by a specialist garage when outside
temperatures are high or when driving on long trips. You should also
check the electrolyte level ⇒page 231 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.

Operation in winter
The battery has to provide greater amounts of electricity during the winter.
It also has only part of the initial power output at low temperatures that it
has at normal temperatures.
A discharged battery may already freeze at temperatures just below
0°C.
We therefore recommend that you have the battery checked by a
specialist garage before the start of the winter, and recharged if neces-
sary.
Note
If the vehicle is not going to be driven for a period of some weeks when
there is very severe frost one should remove ⇒page 232 the battery and
store it in a place which is protected from frost. This prevents the battery
from freezing up and thereby being destroyed.
Charging the battery
A properly charged battery is essential for reliably starting
the engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 228 and ⇒.
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all “negative”, then “positive”). – Carefully attach the terminal clamps of the charger to the
battery terminals (red = “positive”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and switch on the charger.
– When charging is completed: switch the charger off and unplug the mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of the battery if you
recharge the battery using low amperages (as for example from a mini-
charger ). Please also refer to the instructions from the charger manufac-
turer.
A charging current of 0.1 of the total battery capacity (or lower) is that
which should 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” a battery is dangerous ⇒ in “Working on the battery”
on page 228. It requires a special charger and appropriate knowledge. We
therefore recommend that you have your battery quick-charged only by
your specialist garage.
A discharged battery may already freeze at temperatures just below 0°C.
⇒ . We recommend that you no longer use a battery which has thawed
out because the casing of the battery may be cracked through the forma-
tion of ice and this would allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.

⇒page 233.
Note
We do not recommend that you remove and install the battery yourself
(even when you are following the instructions given in this Owner's
manual) since a battery can be heavily damaged in the process under
certain circumstances. Contact a specialist garage.
Disconnecting and reconnecting the battery
On disconnecting and reconnecting the battery the following functions are
initially deactivated or are no longer able to operate fault-free.
We recommend having the vehicle checked by a specialist garage to
ensure full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity,
voltage (12 V), amperage and of the same size. Specialist garages have
a range of suitable batteries available.
We recommend that you only have an old battery disposed of by a
specialist garage since it does require special disposal.
For the sake of the environment
