vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface.
Make sure the jack is positioned correctly
under the axle housing. Always lower the
vehicle onto sufficient capacity jackstands
before working under the vehicle.
If the vehicle is not raised as described, it

Battery
The battery is located in front of the rear
seat bench and below the cup holder.
Jump starting terminals are located on the
driver’s side of the engine compartment
(
page 400).
The battery should always be sufficiently
charged in order to achieve its rated
service 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
frequently.
When replacing the battery, always use
batteries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
iMercedes-Benz recommends to have the
battery replaced at an authorized
Mercedes-Benz Light Truck Center.
