Maintenance
We strongly recommend that you have 
your vehicle serviced by your authorized 
Mercedes-Benz Center, in accordance with 
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.
FSS will notify you when your next service 
is due.1Knob

Approximately one month before your next 
service is due, the type of service is indi-
cated in the speedometer display2:

Minor service (A)
´
Major service (B)Depending on operating conditions 
throughout the year, one of the following 
service symbols is also shown:
9
 1000 Calculated distance remain-
ing, e. g. service in 
1000 miles (km)
š
  10 Calculated remaining time in 
days, e. g. service in 10 days
Clearing the service indicator
The service indicator is automatically 
cleared after 10 seconds when you switch 
on the ignition or when reaching the ser-
vice treshold while driving. You can also 
clear it yourself.
Press knob1.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.

service.
Calling up the service indicator
Within 1 second press knob1 
(page 185) twice.
The service symbol and the service 
deadline appear in the display2.
Resetting the service indicator
In the event that the service on your vehi-
cle is not carried out by an authorized 
Mercedes-Benz Center, you can reset the 
service indicator yourself.
Switch ignition on and immediately 
press knob1 (
page 185) twice with-
in 1 second.
The present status for days or distance 
is displayed.
Within 10 seconds turn key in steering 
lock to position0.
Press and hold knob1 while turning 
key in steering lock to position2 again.
The present status for days and dis-
tance is displayed once more.
Continue to hold knob1 until you hear 
a signal.
Release knob1.
The service indicator now displays the 
reset interval.
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 Mer-
cedes-Benz Limited Warranty. 
If the battery is disconnected, the days 
of disconnection will not be included in 
the count shown by the service indica-
tor. To arrive at the true service dead-
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

Problem
Possible cause
Suggested solution
?
The yellow “CHECK ENGINE” 
malfunction indicator lamp 
comes on while driving.
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive 
emissions values and may switch the engine 
to its limp-home (emergency operation) 
mode.
Have the vehicle checked as soon as 
possible by an authorized 
Mercedes-Benz Center.
An on-board diagnostic connector is 
used by the service station to link the 
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through 
the readout of diagnostic trouble 
codes. It is located in the passenger 
compartment near the engine hood 
release.
The fuel cap is not closed tight.
Check the fuel cap.
Your gas tank is empty.
After refuelling, start the engine three 
or four times in succession. 
The limp-home mode is canceled. You do 
not need to have your vehicle checked.
<
The red seat belt warning lamp 
blinks for a brief period after 
starting the engine.
The warning lamp reminds you to fasten seat 
belts.
