Index
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 
key is in starter switch position 0. The battery must 
always be securely installed when the vehicle is 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:
The gear selector lever will remain locked in 
position “P” and the electronic key can not be turned in 
the starter switch, if the vehicle battery is disconnected 
or discharged.
After reconnecting the battery also set the clock (see 
COMAND operator’s manual), synchronize the 
electronic stability program (ESP) (see page 244) and 
the front seat head restraints (see page 47).
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.
