Checking the battery condition
Fig. 142
Vehicle battery: Electrolyte level
indicator
Read and observe and on page 126 first.
The battery condition is checked regularly by a specialist garage as part of the inspection service.
Check the acid level
For car batteries with acid level indicator, acidity can be checked on the basis
of a colour display. In vehicle batteries with the label “AGM” there is no acid
level examination.
Air bubbles can influence the colour of the indicator. For this reason carefully
tap on the indicator before carrying out the check » Fig. 142.
Black colour – electrolyte level is correct.
Colourless or light yellow colour – electrolyte level too low, the battery must
be replaced.
Battery discharge
If frequent short journeys are made, the vehicle battery does not recharge suf-
ficiently.
The battery capacity decreases at low temperatures.
If the vehicle is not used for longer than 3 to 4 weeks, then disconnect the
negative terminal  of the battery or charge the battery constantly with a very
low charging current.
