Remove the key if you park the vehicle

and do not require any electrical

consumers. The vehicle will then use very

little energy, thus conserving battery

power.

Mercedes-Benz recommends that you do not

carry out work on batteries yourself, e.g.

removing, charging or replacing. Always have

this work performed at a qualified specialist

workshop, e.g. an authorized Mercedes-Benz

Center.

Charging the battery

Warning

Never charge a battery while still installed in

the vehicle unless the accessory battery

charge unit approved by Mercedes-Benz is

being used. Gases may escape during

charging and cause explosions that may

result in paint damage, corrosion or personal

injury.

An accessory battery charge unit specially

adapted for Mercedes-Benz vehicles and

tested and approved by Mercedes-Benz is

available. It permits the charging of the

battery in its installed position. Contact an

authorized Mercedes-Benz Center for

information and availability.

Charge the battery in accordance with the

separate instructions for the accessory

battery charger.

G

Warning

There is a risk of acid burns during the

charging process due to the gases which

escape from the battery. Do not lean over the

battery during the charging process.

G

Warning

Battery acid is caustic. Avoid contact with the

skin, eyes or clothing.

Only charge the installed battery with a

battery charger which has been tested and
