System learning
The Tire Pressure Monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings. During
this process, the Tire Pressure Monitoring recognizes
the tires and their locations.
The on-board computer displayes the message
“TPM is learning, monitoring not act.”.
158 Instruments, On-Board Computer, Warnings
The 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 on-board-computer:
– The tire pressure warning light remains lit until
all wheels have been learned.
– The display of the tire pressure function of the
on-board computer shows lines.
– The required pressures for cold tires at 68 °F
(20 °C) are indicated in the Info pressure
display in the tire pressure menu.
Position and pressure information is displayed as
soon as the Tire Pressure Monitoring has assigned
the wheels identified as belonging to the
vehicle to the correct wheel positions.
The wheel learning process takes place
exclusively when the vehicle is being driven
(vehicle speed above 25 km/h (16 mph)).
f Check the tire pressure for all wheels on the
“Info pressure” display.
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 the Tire Pressure Monitoring.
Before tires are changed, the battery charge
state of the wheel transmitters should be
checked at an authorized Porsche dealer.
f Switch the ignition off when changing a wheel.
The tire settings on the on-board computer must
be updated after changing a wheel.
If the tire settings are not updated, the message
“Wheel change? Input new TPM settings!” is
displayed on the on-board computer.
f Update the on-board computer settings when
the vehicle is stationary the next time.
