Instrument Panel and Multi-Function Display
If necessary, fill in tire sealant and set the
correct tire pressure.
This tire pressure warning also appears when
driving and can be acknowledged.
The tire pressure warning light on the instrument
panel goes out only when the tire pressure has
been corrected.
System learning
Tire Pressure Monitoring begins to “learn” the
wheels after a
wheel change, wheel transmitter
replacement or update of the tire settings
. During
this process, Tire Pressure Monitoring recognizes
the wheels and their locations.
The following message appears on the multi-
function display (example):
“No monitoring, system is learning”.
The wheel learning process takes place
exclusively when the vehicle is being driven
(vehicle speed above 16 mph (25 km/h)).
Tire Pressure Monitoring requires a certain
amount of time to learn the wheels. During this
time, the current tire pressures are not available
on the multi-function display:
– The tire pressure warning light remains lit until
all wheels have been learned.
– Lines (-.-) appear on the display of the
“Tire pressure” function.
– The required pressures for cold tires (68 °F
(20 °C)) are indicated under “Fill info” in the tire
pressure menu.
Position and pressure information is displayed as
soon as Tire Pressure Monitoring has assigned
the wheels recognized as belonging to the vehicle
to the correct wheel positions.
f
Check the tire pressure for all wheels under
“
Fill info
”.
f
Correct the tire pressure to the required
pressure if necessary.
Changing a wheel and replacing tires
f
New wheels must be fitted with radio
transmitters for Tire Pressure Monitoring.
Before tires are changed, the battery charge
condition of the wheel transmitters should be
checked.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
f
Switch off the ignition when changing a wheel.
The tire settings on the multi-function display must
be updated after changing a wheel.
If the tire settings are not updated, the message
“Tire change? Update settings!” is displayed on the
multi-function display.
f
Update the multi-function display settings the
next time the vehicle is stationary.
Pressure increase as the result of
temperature increase
In accordance with physical principles, the tire
pressure changes as the temperature
changes.The tire pressure increases or decreases
by 0.1 bar (1.5 psi) for
every 18 °F (10 °C) change in temperature.
Partial monitoring
Monitoring of the other wheels is continued if there
is a fault in one or two wheel transmitters.
– The tire pressure warning light lights up.
– The message “Restricted monitoring” appears
on the multi-function display.
– No tire pressures are displayed on the
multi-function display for wheels with faulty
wheel transmitters.
