cluster displayPractical hints Car care Index 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 display 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 starter switch to
position 2, or while driving when reaching the service
warning threshold.
The symbols and messages indicate the type of service
to be performed:
9Service A
½Service 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 – PERFORM SERVICE”
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 starter switch to position 2.

When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

Tire inflation pressure monitor (optional for Canada)
The tire inflation pressure, as selected by the driver, is
monitored in all four wheels on the ground. A warning
is issued to the driver in the case of a decrease in the
inflation pressure in one or more of the tires.Inquiry of present tire inflation pressure
Press è or ÿ button on the multifunction
steering wheel until the display for trip and main
odometer appears, see page 122.
Press the j or k button repeatedly until the tire
inflation pressure monitor is displayed.
The present tire inflation pressure for each wheel is
displayed in multifunction display.
Wa r n i n g !
The tire inflation pressure monitor does not
indicate a warning for wrongly selected inflation
pressures. Always adjust tire inflation pressure
according to the label affixed on the fuel filler flap.
See page 356 for tire inflation pressure.The tire inflation pressure monitor is not able to
issue a warning due to a sudden loss of pressure
(e.g. tire puncture caused by a foreign object). In
this case bring vehicle to a halt by carefully
applying the service brakes and avoiding abrupt
steering maneuvers.

Following a tire inflation pressure reactivation process
the real tire inflation pressures are displayed only after
a few minutes travel time.
Possible differences between readings of a tire pressure
gauge of an air hose, e.g. gas station equipment, and the
vehicle’s multifunction display can occur. The vehicle’s
multifunction display of the tire inflation pressure
monitor is a more precise reading.Activation of tire inflation pressure monitor
Activation of tire inflation pressure monitor is
necessary if tire inflation pressure is being changed,
wheels or tires are replaced, or new wheels are installed
on the vehicle.
Tire inflation pressure should be checked and corrected
according to the label affixed inside the fuel filler flap.
For a detailed description, refer to page 356.

cluster displayPractical hints Car care Index Notes:
To ensure proper functioning of the tire inflation
pressure monitor, the tire inflation pressure should be
checked and corrected according to the label affixed
inside the fuel filler flap. For a detailed description,
refer to page 356.
The message “REACTIVATE – TIRE PRESS. MONITOR”
appears if the tire inflation pressure shows an increase
of 4.4 psi (0.3 bar) or more. Reactivate the tire inflation
pressure monitor.
The tire inflation pressure monitor only functions on
wheels equipped with the proper electronic sensors.
Inquire at your authorized Mercedes-Benz Center about
retrofitting other than original Mercedes-Benz wheels
with electronic sensors.
Transporting a deflated road wheel in the vehicle, e.g.
after having a flat, the tire inflation pressure monitor
should only be activated once the flat tire and rim are
removed from the vehicle.To prevent possible damage to the electronic sensors,
have tire changes only performed at an authorized
Mercedes-Benz Center.
For malfunction and warning messages, see page 309.
When checking the tire inflation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 346 for location of the spare wheel, and
page 356 for tire inflation pressure.
