Removing and installing battery: Notes

The battery is located in the radiator tank.
In order to avoid triggering the alarm siren (installed on right next to the battery) of vehicles with M 536, the battery must be disconnected with the ignition on!
All loads must be switched off beforehand! Remove ignition key!
Never disconnect battery with engine running!
Never start engine without securely connected battery!
The battery terminal clamps should only be attached without force to prevent damage to the battery housing.
Battery terminals should not be greased.
Check that the battery is seated correctly after installation. Other dangers exist with a loose battery such as: Reduced service life due to vibration damage. Damage to the grid plates of the battery. Damage to the battery housing through the retaining bracket (possible acid teak, high subsequent costs). Inadequate crash safety.
