Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, do so with
added caution. Contact an authorized
Mercedes-Benz Light Truck Center as soon
as possible.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit am-
bient light conditions.

Resetting trip odometer
Make sure you are viewing the trip odome-
ter display (
page 147).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 148) repeatedly until
the trip odometer appears in the multi-
function display.
Press and hold reset button2 in the
instrument cluster (
page 145) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(
page 26) denotes excessive engine
speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in the
multifunction display (
page 147).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 com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
