Tachometer
The tachometer shows engine speed in re-
volutions per minute (rpm).
The red mark at the end of the scale indi-
cates 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.
Indicator system for position
of gearshift
Automatic transmission
Whenever the ignition is switched on, or the
vehicle lights are switched on, the position
of the gearshift lever lights up in the display
field of the instrument cluster.
The display goes off when the key is re-
moved or when the vehicle lights are
switched off.
Speedometer
The speedometer indicates driving speed
per hour.
In USA: miles per hour

The odometer reading and the readings for
tripmeters I and II appear in the information
system display.
