The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life. Refer to Service Booklet for bat-
tery maintenance intervals.
If you use your vehicle mostly for short-dis-
tance trips, you will need to have the bat-
tery 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 Center about
steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.

and precautions when handling
automotive batteries.

the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.

is due.
Approximately one month before your next
service is due, one of the following mes-
sages will appear in the multifunction dis-
play while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XXXXX MILES (KM)
SERVICE A IN XXX DAYS
SERVICE A IN X DAY
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:9

Clearing the service indicator
The service indicator is automatically
cleared after 30 seconds. You can also
clear it yourself.
Press the reset button on the instru-
ment cluster (
page 22).
Service term exceeded
If you have exceeded the suggested ser-
vice term, you will see the following mes-
sage in the multifunction display:SERVICE A EXCEEDED BY XXXX MILES (KM)
SERVICE A EXCEEDED BY XXX DAYS
SERVICE A EXCEEDED BY X DAYAn acoustic signal will also sound.
The Mercedes-Benz Center will reset the
service indicator following a completed

iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

iIf the battery is disconnected, the days
of disconnection will not be included in

line, you will need to subtract these
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator
with the engine oil level indicator :.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.
