WARNING
It is prohibited to work with naked flames or lights.
■
It is prohibited to smoke or carry out any activities that produce sparks.
■
Never use a damaged vehicle battery – risk of explosion!
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
■
chemical burns!
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of ex-
■
plosion and chemical burns.
WARNING
When you charge a battery, hydrogen is released, and a highly explosive gas
■
mixture is also produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
Creating a bridge between the poles on the battery (e.g. with a metal object
■
or cable) creates a short circuit - risk of melting the lead bars, and risk of ex-
plosion, battery fire and acid splashes.
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 and all of the electrical components and disconnect the negative
terminal ( ) on the battery.
CAUTION
Improper handling of the battery can lead to damage. We recommend having all
work on the vehicle battery carried out by a specialist garage.
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 disconnect
the battery's negative terminal ( ), followed by the positive terminal ( ).
When connecting the battery to the electrical system, first connect the battery's
■
positive terminal ( ), followed by the negative terminal ( ). Under no circumstan-
ces must the battery cables be connected incorrectly – risk of a cable fire.
Ensure that battery acid does not come into contact with the bodywork – risk of
■
damage to the paintwork.

General Maintenance
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.
