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
pressing button
è or ÿ on the multifunction
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.

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 starter switch to position 1
or 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering
wheel until the display appears. See page 106.
Press button j or k until the FSS indicator
appears.
Press the reset knob on the instrument cluster, see
page 96, for approximately 4 seconds. The multifunction display will show the question:
“DO YOU WANT TO RESET SERVICE INTERVAL? –
CONFIRM BY PRESSING R”
Press the reset knob on the instrument cluster again for
approximately 4 seconds to reset the service indicator.
The new service indicator is displayed with the reset
distance of 10 000 miles (Canada 15 000 km).
If the FSS counter was inadvertently reset, have a
Mercedes-Benz Center correct it.
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet
must be followed to properly care for your vehicle.

Engine oil level indicator
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after turning
off the engine, allowing for the oil to return to the oil
pan.
The message “OBSERVE WAITING PERIOD” will be
displayed if the required waiting period has not been
observed after turning off the engine:
• with engine at operational temperature
approximately 5 minutes. •
with engine not at operational temperature up to
approximately 30 minutes.
The engine oil level check can be repeated after a short
time.
Turn the electronic key in starter switch 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. See page 106.
With the multifunction display showing the trip
odometer and main odometer, press button j or
k on the multifunction steering wheel repeatedly
until the “MEASUREMENT CORRECT ONLY IF VEH.
LEVEL” engine oil level indicator appears. This indicator
is only a reminder. Measurement can be cancelled by
pressing button j or k if the vehicle is not
parked on level ground. An incorrect reading will be
recorded if you do not cancel the measurement. Move
the vehicle to level ground and measure again.
The electronic key in starter switch is not in position 2 if
the “ENGINE OIL LEVEL – SWITCH ON IGNITION”
message appears.
The “ENGINE OIL LEVEL – MEASUREMENT IN
PROCESS” message is displayed after approximately
3seconds.

Notes:
Do not obstruct the air flow by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 171 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode S cannot be switched off. Have
the air conditioner checked by a Mercedes-Benz Center
should this happen.
If the vehicle interior has been heated by direct sunlight
and is very hot, ventilate the interior (open door or
windows for a short period) before driving off.
Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system. Basic setting – automatic mode
In the automatic mode the automatic climate control
cools or heats the interior depending on the direction
and strength of the sunlight, outside temperature and
the selected interior temperature of the vehicle. With
the automatic mode switched off, the air volume and
distribution can still be set manually.
Briefly press left or right
U button. The h, j
and k symbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.
We recommend to set the temperature switches on the
left and right to 72
°F (22
°C). Please make changes from
this setting to suit your personal requirements.
Heating mode:
To lower headroom temperature, use thumbwheel
(4, page 160).
Air conditioning mode:
Open air outlets at dashboard top center (7, page 160)
for an even air distribution.
