You can use the stopwatch to measure any times,
e.g. on the race circuit or on work-related
journeys. Measured lap times can be stored and
evaluated if the vehicle is equipped with Porsche
Communication Management (PCM).
f Please observe the chapter “Sport display” in
the separate PCM operating instructions.
Stopwatch on the instrument panel
The stopwatch has an analogue and a digital
display.
The large pointer of the analogue display
measures the seconds. The two small pointers
measure hours and minutes. The display re-starts
at zero after 12 hours.
Seconds and increments of 1/100th of a second
can be read on the digital display.
The digital display and the display in the on-board
computer can indicate up to 99 hours and
59 minutes.
The stopwatch can be swivelled both to the left
and to the right.
Stopwatch displays:
– on the stopwatch on the instrument panel,
– in the on-board computer menu CHRONO,
– on the performance display in the PCM.
Starting/stopping stopwatch
All stopwatch displays are started and stopped via
the on-board computer menu CHRONO.

off. If the ignition is switched on again within
approx. 4 minutes, the stopwatch will continue to
