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 accom-
panied 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 crea te 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.

Caution
•You must only disconnect the battery if the ignition is switched on,
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 Škoda dealer regarding disposing of the battery.
Note
Please also refer to the guidelines ⇒page 216, also after connecting the
battery.
Battery with a charge level indicator, the so-called
magic eye
There is a so-called magic eye ⇒fig. 160 located on the top of the battery.
This indicator changes its colour in line with the charge state and electro-
lyte level in the battery. The colour serves as an aid to your Škoda dealer
in diagnosing the condition of the battery.
Remove the cover ⇒page 212, fig. 159 and knock the magic eye care-
fully before carrying out the battery check.
•green colour - the battery is adequately charged.
•dark colour - the battery has to be charged
•colourless or yellow - the electrolyte level is too low, no indication
regarding the charge state is possible. The battery must be replenished
with distilled water.
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 Škoda dealer.
WARNING (continued)
•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.
•You must disconnect the negative terminal (-) of the battery
when carrying out work on the electrical system. If you wish to
replace a bulb it is sufficient to switch off the appropriate light.

Caution
If the vehicle has not been driven for more than 4 weeks, the battery will
discharge gradually as a result from electrical components such as the
control units which were not switched off. 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 212, “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 Škoda dealer when outside temper-
atures are high or when driving on long trips. You should also check the
electrolyte level ⇒page 214 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.
Caution
Do not expose the battery to direct sunlight for lengthy periods in order to
protect it from UV rays.
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 Škoda
dealer before the start of the winter, and recharged if necessary.
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 215 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 212 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.

Inspecting and Replenishing215
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– 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 212. It requires a special charger and appropriate knowledge. We
therefore recommend that you have your battery quick-charged only by
your Škoda dealer.
A discharged battery may already freeze at temperatures just below 0°C.
If a battery is frozen, it is essential that it is first of all thawed out before
being charged ⇒. 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.
Removing and installing the battery
WARNING
Never charge a battery which is frozen - risk of explosion!

locking plate.
– Move the battery in the direction of the arrow and pull it out in an upward direction.
– Installation takes place in the reverse order.
Please also refer to the following notes when connecting up the battery
⇒ page 216.
Note
We do not recommend that you remove and install the battery yourself
(even when you are following the instructions given in this manual) since
a battery can be heavily damaged in the process under certain circum-
stances. Please contact your Škoda dealer.
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 Škoda dealer 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. Škoda dealers have a
range of suitable batteries available.
We recommend that you only have an old battery disposed of by your
Skoda dealer 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 protec-
tion regulations and on no account as domestic waste.

– Have the tightening torque checked with a torque wrench as
soon as possible. The tightening torque must be 120 Nm.
The safety wheel bolts on vehicles fitted with them (one safety wheel bolt
per wheel) can only be loosened or tighten up by using the adapter
provided.
It is meaningful to note the code number hammered into the rear side of
the adapter or the rear side of the safety wheel bolts. You can obtain a
replacement adapter from a Škoda Dealer, if necessary, by quoting this
number.
We recommend that you always carry the adapter for the wheel bolts with
you in the vehicle. It should be stowed in the vehicle tool kit.
Caution
Damage can occur to the adapter and safety wheel bolt if the safety wheel
bolt is tightened up too much.
Note
The set of safety wheel bolts can be obtained from your Skoda dealer as
an original accessory.
Jump-starting
Initial steps
You 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 insulated 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.
Note
•There must not be any contact between the two vehicles otherwise
current may flow as soon as the negative 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 purchasing jump-start cables from a Skoda dealer as
an original accessory or from retailers who sell branded batteries.
WARNING
•A discharged battery may already freeze at temperatures just
below 0°C. It is essential to thaw out a frozen battery before you
connect the jump-start cables - risk of an explosion!
•Please pay attention to the warning instructions relating to
working in the engine compartment ⇒page 203.

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 ciga-
rettes etc.) away from the battery - risk of an explosion!
