Charging the batteries
You can obtain detailed information on
charging the battery from your authorized
Mercedes-Benz Center.
Charging with the battery charger
Only use the battery charge unit approved
by Mercedes-Benz and supplied with your
vehicle. This charger is designed to auto-
matically control the charge rate, and
charge the battery or maintain the existing
charge in the battery while the vehicle is
parked and not being driven for long peri-
ods of time (on average approximately
3 weeks or more). Not driving the vehicle
for such extended periods may cause the
charge in the vehicle battery to drop.
Using the charging point
The charging point for the battery charger
is located next to the CD-changer on the
left-hand side in the trunk.
1 Charging point
̈ Remove the SmartKey from the starter
switch.
̈ Open the cover of the charging
point 1.
̈ Connect the battery charger with the
charging point 1.
Warning! G
Never charge a battery while still installed in
the vehicle unless the battery charge unit
approved by Mercedes-Benz (supplied with
your vehicle) is being used. Gases may es-
cape during charging and cause explosions
that may result in paint damage, corrosion
or personal injury.
A battery charge unit specially adapted for
Mercedes-Benz vehicles and tested and ap-
proved by Mercedes-Benz is available, per-
mitting the charging of the battery in its
installed position. Contact an authorized
Mercedes-Benz Center for information and
availability. Charge battery in accordance
with the separate operating instructions for
the battery charger.
