Tire Pressure menu - Tire Pressure
Monitoring System (TPMS)
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the infla-
tion pressure recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than
the size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the proper
tire inflation pressure for those tires.)
For information on the tire inflation pressure label:
f
Please see chapter „Tires and Wheels“ on
page 212.
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop, check your tires as soon
as possible, and inflate them to the proper pressure.
Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's respon-
sibility to maintain correct tire pressure, even if
under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
The display as well as the settings for the Tire
Pressure Monitoring System take place on the multi-
function display.
However, the tires still have to be inflated manually.
f
Please see chapter „Tire pressure“ on page 286.
The TPMS offers the following functions:
– Permanent monitoring of tire pressure and tire
temperature.
– Displays the actual tire pressure (actual pressure)
during the trip.
– Tire pressure warnings in two stages (yellow and
red warning).
– Vehicle stationary: Display of the pressure differ-
ence from the required pressure and selection of
tire type and race track mode (718 Cayman GT4
only).
The tire pressure warning light and a corre-
sponding message on the instrument cluster warn
against loss of pressure in two stages (yellow and red
tire pressure warning, depending on the extent of the
pressure loss).
The tire pressure warning light only goes out when
the tire pressure has been corrected to the set
pressure.
The yellow tire pressure warning is displayed for
around 10 seconds after the vehicle comes to a
standstill and the ignition has been switched off or
when the ignition is switched on again. The yellow
tire pressure warning can be acknowledged when the
ignition is switched on. The red tire pressure warning
also appears while driving and can be acknowledged.
e
If the tire pressure warning light comes on and a
tire pressure warning is displayed even with a
correct tire pressure: Visit an authorized Porsche
dealer. Porsche recommends an authorized
Porsche dealer, as they have trained technicians
and the necessary parts and tools.
Information
The tire pressure monitoring system issues warnings
relating to loss of pressure due to natural diffusion
and gradual loss of pressure caused by foreign
bodies.
The tire pressure monitoring system cannot warn
against sudden damage to the tire (e.g., punctures
due to sudden external influences).
WARNING
Incorrect Tire Pressure
Too low or too high tire pressure destroys the tire and
wheel, extends the braking distance, and signifi-
cantly increases the risk of an accident.
Although the tire pressure monitoring system is
available, it is the driver’s responsibility to ensure that
the tires are inflated to the right tire pressure and
that the settings in the TPMS menu are correct.
e
Adapt tire pressure to the fitted tires.
f
Please see chapter „Tire pressure“ on page 286.
e
Make sure that the settings in the TPMS menu on
the multifunction display correspond to the tires
fitted on the vehicle.
After a wheel change, update the settings in the
TPMS menu.
e
Even if a newly fitted set of tires has the same
settings as the previous set, select the tire type
and size again on the multifunction display.
e
Incomplete entries or the wrong choice of tire on
the multifunction display will impact on the
correct output of warnings and notices.
