Tachometer; Turn Signal Indicator Light; High Beam Indicator Light; Cooling System - Porsche 911 Turbo Owner's Manual

Tachometer

The tachometer shows the engine speed in revolu-
tions per minute (rpm).
The beginning of the red marks at the right end of
the scale indicates the maximum permissible en-
gine rpm.
A speed limiter prevents the engine from being
overrevved during acceleration. Before reaching
this area, the next higher gear should be select-
ed.
Shift to the next lower gear when the engine rpm
drops below 1,500 rpm.
Caution!
To avoid severe engine damage.
f Always observe the engine rpm before down-
shifting to a lower gear, so you do not exceed
the maximum engine rpm.
