ent upon the brightness of the ambient light.

Speedometer
If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category (
Y
page 355). If the assignment
changes without recoding the control units in
the vehicle, the speedometer will not display the
speed accurately. 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:

i In some countries, an acoustic signal
sounds and/or the display shows a message
when the vehicle reaches the maximum
legally permissible speed limit, e.g. at
120 km/h.
Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
H
Environmental note
Avoid excessive engine speeds. This unnec-
essarily increases the fuel consumption of
your vehicle and harms the environment as a
result of increased emissions.
The red band in the rev counter 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 the freez-
ing 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:

Changes in the outside temperature are dis-

WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in
the engine compartment, leave the bonnet
closed and notify the fire brigade.
On vehicles without steering wheel buttons, you
can have the coolant temperature shown in the
display (
Y
page 224).
On vehicles with steering wheel buttons, an ana-
logue coolant temperature display is located in
the rev counter in the instrument cluster
(
Y
page 40).
Under normal operating conditions and with the
specified coolant level, the coolant temperature
display:
R
may rise to 110 † on vehicles with an engine
output of under 100 kW.
R
may rise to 120 † on vehicles with an engine
output above 100 kW.
