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. Then disconnect the positive ter-
minal (+).
When reconnecting the battery, first connect the positive terminal (+) and then
■
the negative terminal (-) of the battery. 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 other-
■
wise the paintwork could be damaged.
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.

General Maintenance
Checking the battery electrolyte level
ä
First read and observe the introductory information and safety warn-
ings on page 115.
We recommend you have the electrolyte level checked by a specialist garage from
time to time, especially in the following cases.
›
High outside temperatures.
›
Long daily drives
›
After each charge » page 117, Charging a vehicle battery.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 102, 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.
Note
The battery electrolyte level is periodically checked by a ŠKODA Service Partner
■
as part of the Inspection Service.
For technical reasons, on vehicles with the description "AGM", the electrolyte
■
level 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.
