Fig. 141 In the engine compartment: removing the vehicle battery cover
The electrolyte level of the vehicle battery should be checked regularly in high-mileage vehicles, in hot countries and in older vehicle batteries. The vehicle battery is otherwise maintenance-free.
Vehicles with a start/stop system are fitted with special vehicle batteries. For technical reasons, it might not be possible to check the electrolyte level in these vehicle batteries.
In vehicles with the vehicle battery in the spare wheel well, it is not possible to check the electrolyte level without first removing vehicle parts. Seek expert assistance.
