CHRONO
StopwatchYou can use the stopwatch to measure time inter-
vals, 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).
fPlease observe the chapter “Sport display” in
the separate PCM operating instructions.Stopwatch on the instrument panel
The stopwatch has an analogue and a digital dis-
play.
The large pointer of the analogue display meas-
ures the seconds. The two small pointers measure
hours and minutes. The display re-starts at zero af-
ter 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.Note on operation
When you leave the CHRONO menu while the stop-
watch is running, measurement will continue.
The stopwatch stops after the ignition is switched
off. If the ignition is switched on again within ap-
prox. 4 minutes, the stopwatch will continue to
run.
The only way to reset the stopwatch to zero is by
selecting “Reset” in the CHRONO menu.

Several intermediate times can be displayed for a
route or for a lap on the race circuit. The interme-
diate times B are for your information.
Measured lap times A can be stored and evaluat-
ed if the vehicle is equipped with Porsche Commu-
nication Management (PCM).To display an intermediate time:
After timing has been started, the on-board com-
puter display changes to the “Stop timing/Inter-
mediate time” selection.
fSelect “Intermediate time” with the operating
lever and push the operating lever forwards.The intermediate time will be displayed for
approx. 5 seconds.
The on-board computer display then returns to the
“Stop timing/Intermediate time” selection.
fYou can stop the stopwatch or measure anoth-
er intermediate time.

The “New lap?” selection appears for 5 seconds
after selection of “Intermediate time”.
fSelect “New lap?” with the operating lever and

The new lap is displayed on the on-board compu-
ter and the PCM. Timing on the on-board computer
and on the PCM begins from zero. The stopwatch
in the instrument panel continues to show the total
time.fThe on-board computer display returns to the
“Stop timing/Intermediate time” selection after
a short period.
fYou can stop the stopwatch or measure anoth-
er intermediate time or a new lap.
PCM information

performance display in the “Trip/Sport display/Be-
gin trip” menu of the PCM must be selected.

TPC Tire pressure monitoringfPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 268.
The tire pressure monitoring continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for the tire
pressure monitoring take place on the on-board
computer.
However, you must still adjust the tire pressure on
the wheel.
fThe driver is responsible for filling the tires
correctly and making the correct settings on
the on-board computer.
The tire pressure monitoring offers the following
functions:
– Display of the actual tire pressure while the
vehicle is in motion
– Display of the deviation from the required
pressure (refilling pressure)
– Display of currently set tire size and type
– Tire pressure warnings in two stages
Safety notes!
Despite the advantages offered by the tire
pressure monitoring, it is still the driver’s
responsibility to update the corresponding
settings in the on-board computer and
maintain the pressure in the tires. Low tire
pressure reduces the road safety of the
vehicle and destroys the tire and wheel.
fWhen a flat tire has been displayed, immedi-
ately stop in a suitable place and check the
tires for damage. If necessary, remedy the
damage with a tire sealant.
fDo not by any means continue to drive with
defective tires.
fSealing the tire with tire sealant is only an
emergency repair, so you can drive to the next
authorized Porsche dealer. The maximum per-
mitted speed is 50 mph (80 km/h).
fDo not drive with tires whose tire pressure
drops again in a short period of time. In cases
of doubt, have tires checked by an authorized
Porsche dealer.
fDefective tires must be immediately replaced
by an authorized Porsche dealer.
Tire repairs are not permissible under any
circumstances.fIf the tire pressure monitoring is defective (e.g.
defective wheel transmitter), contact an
authorized Porsche dealer immediately and
have the damage repaired.
The tire pressure will not be monitored by a
defective tire pressure monitoring.
fTires lose air over time without a tire defect
being present. A tire pressure warning will then
appear in the on-board computer display.
Correct the tire pressure at the next oppor-
tunity.
fThe tire pressure monitoring gives a warning
about tire damage due to natural pressure loss
as well as about a gradual loss of pressure due
to foreign objects.
The tire pressure monitoring cannot warn you
about tire damage that occurs suddenly (e.g.
flat tire due to abrupt external effects).

104
Controls, Instruments Tire pressure function of the on-board
computer
The tire pressure function of the on-board
computer displays the tire pressures (actual
pressure) dependent on temperature in the four
wheels.
You can watch the tire pressure rise as the
temperature increases while driving.
This display is only for information.
fUnder no circumstances should the tire
pressures be changed based on this display.
Calling the tire pressure function of the on-
board computer
fPush operating lever up or down until the tire
pressure function of the on-board computer
appears.
(The selection field must be switched off.)Pressure info in Tire pressure menu
In accordance with physical principles, the air
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 50°F (10°C)
change in temperature.
The tire pressure monitoring takes this relation-
ship between tire pressure and temperature into
account.
You can read the tire pressures to be
corrected in this display.
The tire pressure to be corrected (refill pressure)
is indicated on the displayed wheel.
Example: If “ –1.5 psi (–0.1 bar)” is displayed,
1.5 psi (0.1 bar) must be added to this tire.
Note
The Tire pressure menu can only be called up
when the vehicle is stationary.Calling up the “Info pressure” display
fPush operating lever forward in order to switch
on the selection field.
fSelect “TPC” with the operating lever.
fPush operating lever forward.
The display changes to the Tire pressure
menu.
fSelect “Info pressure” with the operating lever.
fPush operating lever forward.
Note
After the ignition is switched on, it can take up to
approx. 1 minute before all tire pressures are
displayed. Dashes (“-.-”) appear instead of the tire
pressures.

Note
This menu is only displayed when different tire
sizes are approved.fSelect “Continue” and push the operating lever
forward.
Setting of the tire characteristics has only been
successfully completed when the message
“Process complete” is displayed by the on-board
computer.
fSelect arrow (Back) and push the operating
lever forward. The display returns to the Tire
pressure menu.
The on-board computer additionally displays
the message “System learning”.Note
The message “Process aborted” appears if the
setting process is interrupted. All entries made up
to this point are lost, and the original settings
remain in effect.
Only if the message “Process complete” appears
after the settings have been made will the tire
pressure monitoring re-learn the wheels.
fPlease observe the chapter “SYSTEM
LEARNING” on Page 108.
Before fitting tires with sizes which are not stored
in the on-board computer, the missing information
should be supplemented in the on-board
computer.
fConsult a qualified specialist garage. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
fUse only tires approved by Porsche.
The available items in the Tire pressure menu
depend on the equipment of your vehicle. For this
reason it is possible that some of the items shown
here are not available on your on-board
computer’s display.
