Speedometer
If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category (
Ypage 267). 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 displayi n

!
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
ar esult 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.

You should pay special attention to road condi-
tions when temperatures are around freezing
