Maintenance
Clearing the maintenance service 
indicator message
The maintenance service indicator mes-
sage is automatically cleared after approx-
imately 30 seconds when you switch on 
the ignition or when reaching the mainte-
nance service threshold while driving.
You can also clear it yourself.
1Reset button
Press reset button 1 on the 
instrument cluster.The maintenance service indicator 
message is cleared and the standard 
display appears in the multifunction 
display (
page 146).
Maintenance service term exceeded
If you have exceeded the suggested 
maintenance service term, you will see the 
following message in the multifunction 
display:
Service A exceeded by XXXXX miles (km)
Service A exceeded by XXX days
In addition, a signal sounds when the 
message appears.
Any authorized Mercedes-Benz Center will 
reset the maintenance service indicator 
following a completed maintenance 
service.
iVehicles equipped with FSS (Flexible Ser-
vice S
ystem) only (Canada vehicles, depending 
on vehicle production date):
FSS evaluates engine temperature, oil level, 
vehicle speed, engine speed, distance driven 
and the time elapsed since your last service 
and calculates other maintenance service 
work required.
The interval between 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 services.

carrying out the maintenance service will 
find the information for resetting the 
maintenance service indicator in the 
maintenance-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 
message or maintenance service indicator dis-
play.
Do not confuse the maintenance service indica-
tor with the engine oil level indicator:.
iIf the maintenance service indicator was in-
advertently reset, have an authorized 
Mercedes-Benz Center correct it.
Only reset if the proper maintenance service has 
been performed. Resetting the system without 
performing the proper service as called for by 
the maintenance service indicator will result in 
engine damage and/or other vehicle damage not 
covered by the Mercedes-Benz Limited Warran-
ty.
