On vehicles with steering wheel buttons, the
light sensor in the instrument cluster automati-
cally controls the brightness of the display light-
ing.
While the lights are on, the brightness is depend-
ent upon the brightness of the ambient light.
You can also adjust the brightness of the instru-
ment lighting and the display lighting
Rby pressing thefand gbuttons on the
instrument cluster on vehicles without steer-
ing wheel buttons (not in the Settings
menu)
Rby turning brightness control knob :on vehi-
cles 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 (
Ypage 277). If you change wheel
size category without recoding the control 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:

(Ypage 179)
iIn some countries, a warning sounds and/or
the display shows a message when the vehi-
cle 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.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment 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 condi-
tions 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:
Ron vehicles without steering wheel buttons
(Ypage 171)
Ron vehicles with steering wheel buttons
(Ypage 177)
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature gauge
GWARNING
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 (
Ypage 173).
On vehicles with steering wheel buttons, an ana-
log coolant temperature gage is located in the
tachometer in the instrument cluster
(
Ypage 39).
Under normal operating conditions and with the
specified coolant level, the gauge may rise to
248 ‡ (120 †).
