needs to be newly initialized or individual set‐
tings updated, e.g.:▷Seat and mirror memory: store the posi‐
tions again.▷Time: update.▷Date: update.
Disposing of old batteries
Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.

do not replace a defective fuse with a substi‐
