Maintenance
The battery is maintenance-free, i.e., the electrolyte will last for the life of the battery.
Your service center will be glad to advise you on questions regarding the battery.
Battery replacement
Use approved vehicle batteries
only
Only use vehicle batteries that have been approved for your vehicle by the manufacturer; otherwise, the vehicle could be damaged and systems or functions may not be fully available.
After a battery replacement, have the battery registered on the vehicle by your service center to ensure that all comfort functions are fully available and that any Check Control messages are no longer displayed.

In the vehicle, only charge the battery via the starting aid terminals, in the engine compartment with the engine off.

Individual settings need to be reprogrammed:
▷ Seat and mirror memory: store the positions again.
▷ Time: update.
▷ Date: update.
▷ Radio station: save again.
▷ Navigation system: wait for the operability of the navigation.
Disposing of old batteries

Have old batteries disposed of by your service center or bring them to a recycling center.
