Engine revolutions counter
The tachometer
1
» Fig. 18 on page 32 shows the actual engine speed per mi-
nute.
The beginning of the tachometer red scale range indicates the maximum per-
mitted speed for an engine that has been driven-in and has reached operating
temperature.
You should shift into the next highest gear before the red scale of the revolu-
tion counter is reached, or select mode D / S on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 44.
CAUTION
The pointer of the engine revolutions counter must reach the red area for only
a short time - there is a risk of engine damage!

The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights go
out a few seconds after switching on the ignition or after starting the engine.
The warning lights are located at the following positions in the instrument
cluster » Fig. 18 on page 32 .
