– Switch off the ignition and all electrical consumers.
– If fitted, remove the protective foil on the cell sealing plug.
Note
The foil with the warning notices must remain on the battery.
– Remove cell sealing plugs.
– Check the electrolyte level of the battery cells.
The electrolyte level is OK when the fluid level -1- is the same
height as the plastic peg.
Note
The plastic peg corresponds to the max. marking.
If electrolyte level is OK:
– Check the cell sealing plugs and the O-ring seals for damage.
