This tire pressure warning appears
– for approx. 10 seconds with vehicle stopped when switching off the ignition or
– again when switching on the ignition.
With ignition on, the warning can be deactivated.
The tire pressure warning light in the instrument
panel goes out only when the tire pressure has
been corrected. Stage 2 – Flat tire
At speeds
below 100 mph (160 km/h):
The pressure in the tire has dropped by more
than 7 psi (0.5 bar) . This significant pressure
loss is a danger to road safety.
At speeds above 100 mph (160 km/h):
The pressure in the tire has dropped by more
than 5 psi (0.4 bar) . This significant pressure
loss is a danger to road safety.
f When the tire pressure warning appears, stop
immediately at a suitable location. Check the
indicated tire for signs of damage. If neces-
sary, 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.

Instruments, On-Board Computer, Warnings
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 as-
signed 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 tiresfNew wheels must be fitt ed 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.
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.

Warning!
Your vehicle has also be en equipped with a TPM
malfunction indicator to indicate when the system
is not operating properly.
The TPM malfunction indicator is combined with
the low tire pressure telltale.
When the system detects a malfunction, the tellta-
le will flash for approximately 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 indi cator 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 in the speedometer flashes for
approx. one minute and then remains continuously
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.

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 meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car ba ttery 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.
f To correct the tire pressures, always use the
displayed values from the “Info pressure”
display in the tire pressure menu.

Shifting Gears
Manual Transmission, ClutchThe positions of the gears are shown on the shift
diagram on the gearshift lever.
Warning!
Risk of accident, resulting in serious person-
al injury or death.
f Do not obstruct the pedal travel with floor mats
or other objects.
Nonskid floor mats of the correct size are
available at your authorized Porsche dealer. To avoid damage to the clutch and transmis-
sion:
f
Always depress the clutch pedal fully when
changing gears. Make sure that the gearshift
lever is completely engaged.
f Only shift into reverse when the car has come
to a complete stop.
f When shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
f Select reverse only when vehicle is stationary.
Reverse gear can be enga ged after shifting the
gearshift lever as far as possible to the left.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is sele cted and the ignition is
on, the backup lights are illuminated.
Permitted engine speedf You should change into a higher gear before
the needle reaches the red mark on the
tachometer, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
f Take care not to exceed the maximum permitted engine speed when shifting down.
