available and that any Check Control mes‐
sages of these comfort features are no longer

ciently charged to guarantee that the battery
remains usable for its full service life.

lowing cases:

drives.
▷ If the vehicle is not used for prolonged pe‐
riods, longer than a month.

tions again.

Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substi‐
