⇒page 192, fig. 181.
– Pull up the cover in direction of arrow ⇒page 192, fig. 181 (automatic
gearbox) or ⇒page 192, fig. 182 (manual gearbox).
– The installation of the battery cover on the positive terminal side takes
place in the reverse order.Removal and installation of the battery is not recommended since it can, under
certain circumstances, lead to major damage to the battery and fuse boxes. 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 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 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 glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately 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 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, 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! Immediately
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.WARNING (continued)

Inspecting and replenishing 194•
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 environment -
contact your specialist garage regarding disposing of the battery.
Note
•
Please also refer to the guidelines ⇒page 196, “Disconnecting and recon-
necting the battery”, also after connecting the battery.
Battery with a two-tone indicatorAn indicator for the electrolyte level, the so-called magic eye ⇒fig. 183, is located
on the top of the battery. The indicator changes its colour in line with the electrolyte
level in the battery.
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.Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or replaced 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 discon-
necting 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 192.
Note
•
Batteries with two-tone indicator, which are mounted as of factory, are marked
with a code which always begins with 5K0. The exact marking can be e.g.
5K0 915 105 D.
•
Replacement batteries with two-tone indicator, which were obtained from
Škoda original accessories, are marked with the code 000 915 105 Dx, whereby
“x” stands for a variable. 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
⇒fig. 183, is located on the top of the battery. The indicator changes its colour in
line with the charge state and the electrolyte level in the battery.
Air bubbles can influence the colour of the indicator. 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 replaced by a specialist garage.

“x” stands for a variable. 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 specialist garage when outside temperatures are high or when
driving on long trips. You should also have the electrolyte level ⇒page 195
checked each time the battery is charged.
The electrolyte level of the battery will also 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
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 necessary.
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 192 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 “nega-
tive”).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 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”.
s29g.4.book Page 195 Wednesday, June 17, 2009 9:54 AM

Inspecting and replenishing 196“Quick-charging” a battery is dangerous ⇒ in “Working on the battery” on
page 192. 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 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.Disconnecting and reconnecting the batteryOn 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 batteryYou 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.

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.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 in the
front left of the engine compartment ⇒fig. 184.

possible. Steel and light alloy wheels must be tightened to a tightening
torque of 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 specialist garage, 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.
•
On steel wheels, the theft-deterrent wheel bolt must always be installed in the
hole, which is close to the valve. Otherwise the full wheel trim cannot be mounted
and the full wheel trim can be damaged during the assembly.Note
The set of safety wheel bolts can be obtained from a specialist garage.
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! Also
after thawing of the battery there is a risk of caustic burns due to leaking
acid. Replace the frozen battery.
•
Please pay attention to the warning instructions relating to working in
the engine compartment ⇒page 185.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 installed telephone and also pay attention to the instructions for
use of the telephone in such a situation.

We recommend purchasing jump-start cables from Škoda Service Partners as a
Škoda original accessory or from retailers who sell branded batteries.
Start engineIt is important to connect the jump-start cables in the correct order.
Connecting positive terminals
– Attach one end to the positive terminal ⇒fig. 195 of the
discharged battery .
– Attach the other end to the positive terminal of the battery
supplying the power .
Connecting negative terminal and engine block
– Attach one end to the negative terminal 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 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.
•
Do not affix the cable end to parts of the fuel and brake system.
•
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 have a too low electrolyte level -
risk of explosion and caustic burns!
