tailed information on operating, maintain-
ing, and caring for your vehicle.
We strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service indi-
cator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in ve-
hicle damage not covered by the
Mercedes-Benz Limited Warranty.
The maintenance service indicator will no-
tify you when your next maintenance ser-
vice is due.
Starting approximately one month before
maintenance service is due, one of the fol-
lowing messages will appear in the multi-
function display 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
Carry out service AThe maintenance services will be indicated
by showing a service type A through
type H in the multifunction display.
Types A through H are classified based on
estimated time needed to perform the
maintenance service, ranging:
from
Service A(approx. 1 hour)
toService H(approx. 8 hours)
iVehicles equipped with FSS PLUS
(Flexible S

ystem PLUS) only
(Canada vehicles): The interval be-
tween maintenance 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 mainte-
nance services.

352 OperationMaintenance
Resetting the maintenance service indicator
In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can
have the maintenance service indicator re-
set. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your
vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicatorN.
iIf the maintenance service indicator
was inadvertently reset, have an autho-
rized Mercedes-Benz Center correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper maintenance service as called
for by the maintenance service indica-
tor will result in engine damage and/or
other vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
