Adjusting clock (instrument cluster activated):
Minute: Pull out knob (2) and turn it to the right.
Hour: Pull out knob (2) and turn it to the left.
Coolant temperature gauge (1)
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 (2)
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 (11)
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.

•Compass –
The compass displays the direction the vehicle is
traveling, such as N, NE, E, SE, S, SW, W or NW.
Note:
The presence of buildings, bridges, power lines and
large antenna masts can influence the displayed
values. Metallic or magnetic objects in or on the
vehicle can influence the accuracy of the compass.To change the compass zones:
Determine the geographical point of the vehicle with the
aid of the zone maps below:
1. Turn key in steering lock to position 2.
2. Press MODE key repeatedly until the compass
display appears in the trip computer display.

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, rear window defroster etc.) should be switched
off, doors and liftgate closed. Do not open or close the
roof. An open 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 and afterwards press MODE key,
“CAL–” appears in the display.4. Press and hold RESET key for a minimum of
2 seconds, to access the calibration mode.
The display shows “CAL”.
5. Without interruption drive two full circles at a speed
between 3 mph (5 km / h) and 7 mph (10 km / h).
The message “CAL” goes out after a short time.
6. The calibration of the compass is now complete.
Note:
If “CAL” remains in the display, calibration was not
successfully completed. To recalibrate, remove key from
the steering lock. Insert key, start the vehicle and start
the calibration procedure.
We recommend that you have the compass calibrated at
a Mercedes-Benz Light Truck Center.
