Battery with a two-tone indicator
An indicator for the electrolyte level, the so-called magic eye
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 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 222, "Working on the
battery".
