The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life. Refer to Maintenance Booklet for
battery maintenance intervals.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more frequent-
ly.
When replacing batteries, always use
batteries approved by Mercedes-Benz.

for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
