Service B light reset

I did the Service B tasks but can't figure out how to reset it so that the Service B light doesn't come on every time I start the car. It says in the owner's manual to press the reset button on the dash, but that doesn't do the trick.

Here you go:

Flexible service system (FSS)
(service indicator)​
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.

The symbol​
9 or ½ appears together with a
message in the multifunction indicator prior to the next
suggested service.

Depending on operating conditions throughout the year,
the next service is calculated and displayed in days or
distance remaining.

The message is displayed for approximately 10 seconds
when turning the electronic key in steering lock to
position 2, or while driving when reaching the service
warning threshold.

The symbols and messages indicate the type of service
to be performed:


9​
Service A

½​
Service B

One of the following messages will appear in the display
(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – DUE NOW”

The next service due date is displayed either in days or
in miles, depending on your driving style.
Once the suggested service term has passed, the symbol
and message appear for approximately 30 seconds and
a signal sounds every time when turning the electronic

key in steering lock to position 2.

That's

not the reset procedure.That's just what the fss is indicating.
The reset is in my link above and if he has a later model with the fss function buttons on the steering wheel that procedure can also be supplied.
OP post what year in your profile.

Here you go:
Following a completed A or B service the Mercedes-Benz Center sets the counter mileage to 10 000 miles
(Canada: 15 000 km).

The counter can also be set by any individual.

To do so:
Turn the electronic key in steering lock to position 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering wheel until the display appears.
Press button j or k until the FSS indicator appears.
Press button J on the instrument cluster for approximately 4 seconds.

The multifunction display will show the question:

“DO YOU WANT TO RESET SERVICE INTERVAL?
CONFIRM BY PRESSING R”

Press button J on the instrument cluster again for approximately 4 seconds, and hold until a signal
sounds. The message “SERVICE INTERVAL HAS BEEN RESET” appears in the multifunction display.
The new service indicator is displayed with the reset distance of 10 000 miles (Canada 15 000 km).

YUp

that's the one for the later models with the multi function steering wheel,I figure since he said his manual said press the o button he has a pre 01 model and needs to follow the reset procedure in my link.
whenever he posts his year and model in the profile;)
