Parking the vehicle for a long period
If you leave the vehicle parked for longer than four weeks, the battery may be damaged by exhaustive discharge.
Connect a trickle charger.
You can obtain information about trickle chargers from a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
If you leave the vehicle parked for longer than six weeks, the vehicle may suffer damage as a result of lack of use.
Visit a qualified specialist workshop and seek advice.
