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.
The service indicator disappears automatically after
30 seconds or if the knob for instrument cluster
illumination, see page 96, in the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in starter switch to position 1
or 2.
Call up the trip odometer and main odometer by

steering wheel until the display appears. See page 106.
Press button j or k until the FSS indicator
appears.
The next or previous system is displayed by pressing
button è or ÿ . Important!
The FSS indicator is not an engine oil level indicator.
See page 141 for engine oil level indicator.
Note:
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.

Wa r n i n g !
For vehicles equipped with a manual transmission,
getting out of your vehicle with the gearshift lever
not engaged in 1st or reverse gear and parking
brake engaged is dangerous.
Also, when parked on an incline, an engaged 1st or
reverse gear alone may not prevent your vehicle
from moving, possibly hitting people or objects.Always set the parking brake in addition to
engaging 1st or reverse gear, see page 256 for
parking brake. When parked on an incline, also turn front wheel
towards the road curb.When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Children could move
the gearshift lever, which could result in an
accident or serious injury.
Wa r n i n g !
On slippery road surfaces as well as high engine
speeds, never downshift in order to obtain braking
action. This could result in drive wheel slip and
reduced vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
