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, followed by the positive terminal
(+).
When connecting the battery to the electrical system, first of all connect the
■
positive terminal (+) of the battery, followed by the negative terminal (-). 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 – risk of
■
damage to the paintwork.
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.
