WARNING

Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.

If the fluid level has dropped below the MIN marking, do not drive any
further - risk of accident! Obtain professional assistance.
Replacing brake fluidBrake 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.
One may only use new genuine brake fluid from Škoda Auto. The brake fluid must
comply with one of the following standards or specifications:
VW 50114

FMVSS 116 DOT4

DIN ISO 4925 CLASS 4
We recommend that you have the brake fluid replaced by an authorised 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 br ake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle.
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.
BatteryWorking on the batteryFig. 166 Engine compartment: Polyester cover of the vehicle battery / plastic cover of the
vehicle batteryThe battery is located in the engine compartment in a polyester cover fig. 166 - left,
or in a plastic cover* fig. 166 - right.
– Open the battery cover in direction of arrow fig. 166 or press the interlock
on the side of the battery cover, fold the cover up and remove the battery.
– The installation of the battery co ver takes place in the reverse order.
The edge of the polyester battery cover fig. 166 - left is inserted between the battery
and the side wall of the battery co ver when working on the battery.
Removal and installation of the battery is not recommended since it can, under certain
circumstances, lead to major dama ge. Contact a specialist garage.
There is a risk of injuries, scalding, accidents and burns when carrying out any work on
the battery and on the electrical system. For th is 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 prot ective 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 enam el 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 accompanied 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 glas ses or a shield! There is
the danger of suffering blindness! If an y battery electrolyte gets into your eye,
rinse out your eye immediately with cl ear 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 swal low battery electrolyte.

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, explo-
sion 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 el ectrical 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 batt ery - risk of explosion and caustic
burns! Replace a frozen battery.

Never jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns!

Never use a battery which is damaged - risk of explosion! Immediately
replace a damaged battery.
Caution

You must only disconnect the battery if th e 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 ba ttery. 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 other-
wise 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 wa ste which is harmful to the environment -
contact your specialist garage regarding disposing of the battery.
Note
Please also refer to the guidelines page 206, also after connecting the battery.Battery with a two-tone indicator

An indicator for the electrolyte level, the so-called magic eye
page 204, fig. 167 , is
located on the top of the battery. The indicato r changes its colour in line with the elec-
trolyte level in the battery.
Air bubbles can influence the colour of the in dicator. For this reason carefully knock on
the indicator before carrying out the check.

Black colour - electrolyte level is correct.

Colourless or light yellow colour - electr olyte level too low, the battery must be
replaced.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or repl aced 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 consum e 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 wh en working on the battery  in “Working on the battery”
on page 203.

original parts, are marked with the code 000 915 105 Dx, whereby “x” stands for a vari-
able. The exact marking can be e.g. 000 915 105 DB.
Battery with a three-tone indicatorAn indicator for the electrolyte level and the charge state, the so-called magic eye
 page 204, fig. 167 , is located on the top of the ba ttery. The indicator changes its
colour in line with the charge state of and the electrolyte level in the battery.
Air bubbles can influence the colour of the in dicator. For this reason carefully knock on
the indicator before carrying out the check.

Green colour - the battery is adequately charged.

Dark colour - the battery has to be charged.

Colourless or yellow colour - electrolyte level too low, the battery must be
replaced.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or repl aced by a specialist garage.Caution
If the vehicle has not been driven for more th an 3 to 4 weeks, the battery will discharge
because certain electrical co mponents 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  in “Working on the battery”
on page 203.

original parts, are marked with the code 000 915 105 Ax, whereby “x” stands for a vari-
able. The exact marking can be e.g. 000 915 105 AB.
Inspecting the electrolyte levelThe 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 Škoda Service Partner when outside temperatures are high or when driving
on long trips. You should also have the electrolyte level page 206 checked each time
the battery is charged.
The electrolyte level of the battery will al so be checked as part of the Inspection
Service.

Operation in winterThe 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 temper-
atures.
A discharged battery may already freez e at temperatures just below 0°C.
We therefore recommend that you have the battery checked by a Škoda Service
Partner before the start of the winter and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery.Charging the battery
A properly charged battery is essentia l for reliably starting the engine.– Read the warning notes  in “Working on the battery” on page 203 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 th e 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 manufacturer. 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 203. It requires a special charger an d appropriate knowledge. We therefore
recommend that you have your battery quick-charged only by your Škoda Service
Par tner.
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 formation of ice and this would allow
battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING

Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.

Never charge a battery which has a too lo w electrolyte level - risk of explo-
sion and caustic burns.

Technical Data
We recommend having the vehicle checked by a Škoda Service Partner to ensure full
functionality of all electrical systems.
Replacing the batteryYou should only replace a battery with a ne
w battery of the same capacity, voltage (12
V), amperage and of the same size. Škoda Service Partners have a range of suitable
batteries available.
We recommend that you only have an old ba ttery disposed of by your Škoda Service
Partner since it does require special disposal.
For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. They must be
disposed of in accordance with local environmental protection regulations and on no
account as domestic waste.
In view of the problems involved with it s proper disposal, we recommend having
the battery replaced by a specialist garage.
Windshield washer systemThe windshield washer reservoir contains the cleaning fluid for the windscreen or rear
window and for the headlamp cleaning system*. The reservoir is located at the front
right of the engine compartment fig. 168 . The
filling level of the container is about 3 litres and about 5.5 litres on vehicles which
have a headlight washing system.
Clear water is not sufficient to intensively clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessories (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your vehicle is
fitted with heated wind screen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen cleaner
with antifreeze is available. The concentration of methylated spirits must not be more
than 15 %. Please note, however, that the anti freeze protection at this concentration is
only adequate down to -5°C.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution

On no account should you add radiator an tifreeze or other additives to the wind-
screen washer fluid.

If the vehicle is fitted with a headlight cleaning system, you should only add
cleaning products which do not attack the polycarbonate coating of the headlights to
the windscreen washer fluid. Please contac t your Škoda Service Partner, who will tell
you which cleaning agent you can use.

Par tner.Jump-startingInitial stepsYou can use the battery of another vehicle for jump-starting yours if the engine does
not start because the battery on your vehicle is flat. You will require jump-start cables
for this purpose. Both batteries must have a rated voltage of 12 V. The
capacity (Ah) of the battery
supplying the power must not be significantly less than the capacity of the discharged
battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and insu-
lated terminal clamps. Please pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
WARNING

A discharged battery may already freeze at temperatures just below 0°C. In
case of frozen battery carry out no jump-starting - risk of explosion!

Please pay attention to the warning instructions relating to working in the
engine compartment page 197, “Working in the engine compartment”.Note

There must not be any contact between the two vehicles otherwise current may
flow as soon as the negati ve terminals are connected.

The discharged battery must be properly connected to the system of the vehicle.

Switch off any mobile phone, pay attention to the instructions for use of the mobile
phone in such a situation.

We recommend that you purchase the jump -starting cable in the specialist shops

.
– Attach the other end to the positive term inal of the battery supplying the power
.Connecting negative terminal and engine block– Attach one end to the negative termin al of the battery supplying the power .
– Attach the other end to a solid metal part which is connected firmly to the
engine block, or to the engine block itself.Starting the engine– Start the engine of the vehicle providing current and run the engine at idling speed.
– Now start the engine of the vehicle with the discharged battery.
– Interrupt the attempt at starting an engine after 10 seconds if it does not start right
away and wait for about 30 seconds before repeating the attempt.
– Disconnect the cables on the engine in exactly the reverse order they were
connected up.
WARNING

The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal of
the battery must not come into contact with electrically conducting parts of the
vehicle - risk of a short circuit!

Do not affix the jump starting cables to the negative terminal of the
discharged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started.

Run the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.

Do not bend over the batteries - risk of caustic burns!

The vent screws of the battery cells must be tightened firmly.

Keep any sources of ignition (naked flame, smouldering cigarettes etc.)
away from the battery - risk of an explosion!

Never jump-start the batteries which ha ve a too low electrolyte level - risk
of explosion and caustic burns!
