Vehicle battery
Maintenance
The battery is maintenance-free, i.e., the elec‐
trolyte 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 availa‐
ble.◀
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort functions are fully
available.
Charging the battery
In the vehicle, only charge the battery via the
terminals, refer to page  268, in the engine com‐
partment with the engine off.
Power failure
After a temporary power loss, some equipment
needs to be reinitialized.
Individual settings need to be reprogrammed:
▷ Seat, mirror, and steering wheel 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 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. Fuses
Notes
Replacing fuses
Never attempt to repair a blown fuse and
do 
not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box in
the cargo area.
In the glove compartment Push the handle up, arrow 1, and open the lid,
arrow 2.
In the cargo area
Open the cover on the right side trim.
Information on the fuse types and locations is
found on a separate sheet. Seite 265
