Instruments, On-Board Computer 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 learningThe 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 recog-
nizes the tires and their locations.
The on-board computer displayes the message
“TPM is learning, monitoring not act.”.
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 16 mph (25 km/h)).
fCheck the tire pressure for all wheels on the
“Info pressure” display.
fCorrect the tire pressure to the required
pressure if necessary.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio transmit-
ters 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.
fSwitch 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.
fUpdate the on-board computer settings when
the vehicle is stationary the next time.

Warning!
Your vehicle has also been equipped with a Tire
Pressure Monitoring (TPM) malfunction indicator
when the system is not operating properly.
The TPM malfunction indicator is combined with a
low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approx. one minute and then
remain continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfuntions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPM to continue to
function properly.The warning light in the speedometer lights up:
– When a loss in pressure has been detected.
– When learning newly mounted wheels/wheel
sensors, as long as the vehicle’s own wheels
have not yet been recognized.
In the event of a defect in Tire Pressure Monitoring
or a temporary fault, the warning light in the
speedometer flashes for approx. one minute and
then remains continuously illuminated.
The tire pressure warning light in the instrument
panel goes out only when the cause of the fault
has been rectified.
Partial monitoringMonitoring 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 “TPM partial monitoring” is
displayed on the on-board computer.
– No tire pressures are displayed on the on-
board computer for wheels with faulty wheel
transmitters.
No monitoringIn the event of faults the Tire Pressure Monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel flashes
for approx. one minute and then remains conti-
nuously illuminated and a corresponding message
appears on the on-board computer.
Monitoring is not active when:
– the Tire Pressure Monitoring is faulty,
– wheel transmitters for the Tire Pressure
Monitoring are missing,
– during the learning phase after the tire settings
have been updated,
– after a wheel change without updating the tire
settings,
– more than four wheel transmitters are
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.
fPlease see the chapter “WARNINGS ON THE
INSTRUMENT PANEL AND THE ON-BOARD
COMPUTER” on Page 148.

At speeds below 100 mph (160 km/h):

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 18 °F (10 °C)
change in temperature.
The Tire Pressure Monitoring takes this relation-
ship between tire pressure and temperature into
account.
Tire pressure specificationsInformation on tire pressure for public roads can
be found in this Owner's Manual in the Technical
Data chapter or on the tire-pressure plate in the
left door aperture.
These values apply to cold tires at 68 °F (20 °C)
ambient temperature.

OIL
Display and measurement of the engine
oil level
Caution!
Risk of engine damage.
fRegularly check the oil level each time before
refueling.
fDo not allow the oil level to fall below the minimum mark.
Conditions for measuring the oil level
1. Vehicle stationary.
2. It is important to ensure that the vehicle is on
a level surface for correct oil level measure-
ment to occur.
3. Engine must be at operating temperature
(at least 140 °F/60 °C oil temperature).
4. Engine must be idling.Initiating oil level measurement
1. Push operating lever forward in order to switch
on the selection field.
2. Select “OIL” with the operating lever.
3. Push operating lever forward. Measurement is
started. 4. Allow waiting time to elapse.
5. Once the measurement has been completed,
you can read off the engine oil level on the
segment display.

Instruments, On-Board Computer 6. If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
Under no circumstances add engine oil.7. If only the bottom segment is filled in, the oil
level has reached the minimum mark.
Add engine oil immediately.
8. If the bottom segment flashes, the oil level has
dropped to below the minimum mark.
Add engine oil immediately.
The difference between the minimum and
maximum marks on the segment display is
approx. 1.1 quarts (1.0 liters).
One segment of the display between the minimum
and maximum marks corresponds to a top-up
quantity of approx. 0.32 quarts (0.3 liter).fAdd engine oil if necessary.
Switch off ignition before adding engine oil.
fPlease see the chapter “ENGINE OIL LEVEL”
on Page 160.
fNever add more engine oil than required
to reach the maximum mark.
Failure
A failure of the oil level display is indicated by a
warning message on the on-board computer.
Display “Check oil level”
The on-board computer display “Check oil level” is
an additional reminder to you to check the oil level.
The display depends on the distance travelledand
the operating conditions, and does not indicate
whether or not the oil level is correct.

General information regarding the
on-board computer functionsRange on remaining fuel
The range on remaining fuel is continuously recal-
culated during the journey based on the fuel level,
current consumption and average consumption.
The more the fuel level falls, the more spontan-
eously the display reacts. For this reason, the
range on remaining fuel is not displayed if less
than 9 miles (15 kilometers).
If the vehicle's inclination changes while driving or
refueling, incorrect range information may
temporarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on
remaining fuel is impossible.Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to “zero”.
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the
measurements. It is therefore possible to collect
values over long periods.
Disconnecting the car battery will cause these
memories to be erased.
Tire pressure
The Tire pressure function of the on-board
computer displays the tire pressures dependent
on temperature in the four wheels. You can watch
the tire pressure rise and fall while driving.
The display is only for information.
fTo correct the tire pressures, always use the
displayed values from the “Info pressure”
display in the tire pressure menu.
