must not leak acid when upside down for at least
15 minutes. Your authorized Mercedes-Benz Center can
provide such a special battery.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in steering lock position 0. The battery,
its filler caps, the vent tube and the opposite plug must
always be securely installed when the vehicle in operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.
Note:
After reconnecting the battery also resynchronize the
front seat head restraints, the express feature of the
power windows, and the electronic stability program
(ESP), see page 46, 156 and 229.
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
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.

1Cross bar
2Knurled-head screws

plates (3) to side.
2. Mount cross bar (1) on roof railings.

Important!
Do not use the pop-up feature of the sliding / pop-up roof
when positioning and / or placing luggage above it, to

Long cargo items should not extend beyond the vehicle
length and should be securely fastened at the front and
rear.
Prior to and during an extended trip check the roof load,
and retighten the knurled-head screws if necessary.
The heaviest portion of the cargo should always be kept
as low as possible since it influences the handling
characteristics of the vehicle.
When driving without roof luggage, the cross bars may
be removed to reduce wind noise.
For load capacity see page 321.Note:
Use only roof racks approved by Mercedes-Benz. They
mount to the roof railings and do not require additional
supports (e.g. suction cups or legs). Such supports may
lead to marring of the paint or denting of the roof. For
further information inquire at your Mercedes-Benz
Center.
