2020 MERCEDES-BENZ METRIS light

In daylight, the displays in the instrument clus-
ter are illuminated. A dimming function is not
possible in daylight.
On vehicles with steering wheel buttons, the
light sensor in the instrument cluster automat-
ically controls the brightness of the display
lighting.
While the lights are on, the brightness is
dependent upon the brightness of the ambient
light. You can also adjust the brightness of the
instrument lighting and the display lighting:
R by pressing the f and g buttons on the
instrument cluster on vehicles without
steering wheel buttons (not in the Settings
menu)
R by turning brightness control knob : on
vehicles with steering wheel buttons Speedometer
If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category ( Y page
278). If you change
wheel size category without recoding the con-
trol unit, the speedometer indication will be
inaccurate. The current vehicle speed may
then be higher than the speed displayed in the
speedometer.
The speed can also be shown in the display in
the form of a digital speedometer:

and/or the display shows a message when
the vehicle reaches the maximum legally
permissible speed limit, e.g. at 75 mph
(120 km/h). Tachometer
! Do not drive in the overrevving range, as
this could damage the engine. H
Environmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consump-
tion of your vehicle and harms the environ-
ment as a result of increased emissions. The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freezing
point.
Please bear in mind that the outside tempera-
ture display shows the air temperature meas-
ured and not the road temperature.
The display shows the outside temperature in
the header:
R on vehicles without steering wheel buttons

(Y page 183)

played after a short delay. Coolant temperature gauge

WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
On vehicles without steering wheel buttons,
you can have the coolant temperature shown
in the display

(Y page 178).
On vehicles with steering wheel buttons, an
analog coolant temperature gauge is located
in the tachometer in the instrument cluster
(Y page 40). Under normal driving conditions and at the
correct coolant level, the display may rise to
the letter H or to the red mark. Display and operation
