If the “CHECK ENGINE” malfunction
indicator lamp comes on when the engine is
running, it indicates a malfunction of the
fuel management system, emission control
system, systems which impact emissions, or
the fuel cap is not closed tight. In all cases,
we recommend that you have the
malfunction checked as soon as possible, see
page 218. Additional function indicator lamps
(in the odometer display)
FSS indicator (Service A), see page 87
FSS indicator (Service B), see page 87
The symbols appear in the main odometer display field
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. See page 87 for notes on the flexible service
system (FSS).

Coolant temperature gauge
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.
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.

Outside temperature indicator
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.).
Adaptation 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. Tachometer
The tachometer displays the present engine speed in
revolutions per minute (RPM).
To help protect the engine, the fuel supply is interrupted
if the engine is operated above its specified limit.
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.

key repeatedly to illuminate the display and scroll
through menu for one of the following options:
1. Date, see page 84.
2. Compass, see page 84.
3. Stop watch, see page 86.
4. Present fuel consumption – displays miles per gallon or liters pe r 100 km.
5. Average fuel consumption – displays miles per gallon or liters per 100 km, see page 86.
6. Distance remaining with fuel presently in tank. Note:
The display f lashes when fuel supply drops to the
reserve level. The distance remaining is no longer
shown.
7. Language – Press RESET key until the desired language is displayed. Depending on language
selected, information is displayed in that country’s

To calibrate the compass:
If the vehicle was exposed to a significant magnetic
zone, such as high voltage power lines, the compass
may have to be calibrated.
Calibration of the compass should be done in an area
free of steel superstructures and power lines. All
electrical consumers (e.g. exterior lamps, climate
control, etc.) should be switched off, doors and liftgate
closed. Do not open or close the roof. An open door or
liftgate triggers the display “–––”.
1. Start and run the engine.
2. Press MODE key repeatedly until the compass display appears in the trip computer display.
3. Press RESET key to select the compass zone display.
4. Press RESET repeatedly until the correct zone, as determined from the zone map (see page 85), is
shown in the display.
5. Press MODE key, “CAL–” appears in the display.
6. Press and hold RESET for a minimum of 2 seconds. 7. Without interruption drive two or more full circles
at a speed between 3 mph (5 km / h) and 7 mph
(10 km / h) during which the message “CAL” is
replaced with a compass bearing (e.g. N, SW etc.),
immediately followed by three full circles at the
same speed, with only the rear window defroster
switched on. The defroster can be switched off
again. The calibration of the compass is now
complete.
• Stop watch –
Press RESET key to start the count. Press again to
stop the count. Press and hold RESET key to reset
