e
Tire pressure e Fill info
The pressure difference from the set pressure on the
relevant wheel is displayed.
Example: If the reading for the right rear tire is shown
as –1.4 psi (-0.1 bar), this tire needs to be inflated
by 1.4 psi (0.1 bar). The tire temperature has already
been taken into account in the pressure shown.
e
You should only use the pressure difference from
the display or the corresponding tire pressure
warning to correct the tire pressure.
In the case of tires that have not yet been taught,
the new target pressures are displayed instead of the
actual pressure differences.
Selecting the tire type (fitted tire type and
tire size)
Information
The options available depend on the model type. It is
therefore possible that not all the options shown here
are available on the multifunction display.
e
Before fitting tires with dimensions not stored on
the multifunction display, first add the missing
information on the multifunction display.
Visit an authorized Porsche dealer. Porsche rec-
ommends an authorized Porsche dealer, as they
have trained technicians and the required parts
and tools.
e
Only use tires approved by Porsche.
b Vehicle is stationary.

TPMS e Tire type
Available setting and abbreviation:
–
20" Summer: 20" (S)
–
20" Winter: 20" (W)
The selected setting appears as an abbreviation in
the TPMS main menu in the Tire type line.
Teaching the Tire Pressure Monitoring Sys-
tem (TPMS)
After the tires have been changed, the wheel sen-
sor has been replaced, or the tire settings have
been updated, the Tire Pressure Monitoring System
information about the tires starts to be taught-in.
The Tire Pressure Monitoring system recognizes the
wheels and their installation position. The position
and pressure data is available as soon as the Tire
Pressure Monitoring system has assigned the recog-
nized wheels to the correct wheel position.
Roadside Assistance
During the learning process, the target pressures for
cold tires (68°F/20 °C) are displayed in the inflation
info and the message No monitoring, system learns
from 15 mph (25 km/h) appears in the multifunction
display.
The tire pressure warning light
on the instrument
panel stays lit until all the wheels have been taught.
g Refer to chapter "Warning lights and light indica-
tors" on page 107.

b 718 Cayman GT4 RS
For driving on the race track, pressures deviating
from road mode can be set and monitored.
Race track mode is not designed for public road traf-
fic.
This allows the experienced driver to adapt the tire
pressure individually to the race track in order to
achieve optimum handling.
Tire pressure too low
WARNING
Despite the Tire Pressure Monitoring System, re-
sponsibility for selecting the set tire pressures for
driving on a race circuit is always the responsibility of
the driver.
e
Adjust the required pressures to the maximum
speeds to be driven.
Take into account the warning thresholds that
result in the output of a tire pressure warning.
e
For information on warning thresholds and tire
pressure warnings:
