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.
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 XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
speedometer display field:9

You can also clear it yourself.

Press the reset knob on the instrument
cluster (
page 22).

ly reset, have a Mercedes-Benz Center

engine damage not covered by the
Mercedes-Benz Limited Warranty.
