During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.Outside temperature indicator (6)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaption to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Note:
The unit for the temperature indicator display can be set
in the individual setting menu “INST. CLUSTER” –
“TEMP. INDICATOR”, see page 142.
Wa r n i n g !
• Driving when your engine is badly overheated
can cause some fluids which may have leaked
into the engine compartment to catch fire. You
could be seriously burned.• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it. Turn off
the engine, get out of the vehicle and do not
stand near the vehicle until it cools down.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

Important!
The FSS indicator is not an engine oil level indicator.
See page 157 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
wi t h short di stan ce d r ivi ng in which the e ngin e d oes not
reach operating normal temperature, reduce the interval
between services.

cluster displayPractical hints Car care Index
Notes:
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 351.
Turn electronic key in starter switch to position 2 (the
engine must not be running).

To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after stopping
the engine, allowing for the oil to return to the oil pan.
The message “OBSERVE WAITING PERIOD” (perform
service [engine oil level check] on time) will be
displayed if the required waiting period has not been
observed after stopping 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.

buttonè orÿ on the multifunction steering
wheel until the display appears. See page 124.
Press buttonj ork on the multifunction
steering wheel repeatedly until the “CORRECT
MEASUREMENT ONLY – IF VEHICLE LEVEL” engine oil
level indicator appears. This indicator is only a
reminder. Measurement can be cancelled by pressing
buttonj ork 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 – IGNITION ON PLEASE”
message appears.
The “ENGINE OIL LEVEL – MEASUREMENT IN
PROCESS” message is displayed after approximately
3seconds.
