Tachometer
The tachometer shows engine speed in revolu-
tions per minute (rpm).
The red mark at the end of the scale indicates
the maximum permissible engine rpm. Before
reaching this area, the next higher gear should
be selected. Earlier shifting saves fuel.
Shift to the next lower gear when the engine
rpm drops below 1500 rpm.
The speed limiting governor prevents the engine
from being overrevved under load.
Indicator system for position of
gearshift
Automatic transmission
Whenever the ignition is switched on, or the ve-
hicle lights are switched on, the position of the

The display goes off when the key is removed
or when the vehicle lights are switched off.
Speedometer
The speedometer indicates driving speed per
hour.
In USA: miles per hour
In Canada: kilometers per hour
The odometer reading and the readings for
tripmeters I and II appear in the information sys-
tem display.
