Before fitting tires with sizes which are not stored
in the on-board computer, the missing information
should be supplemented in the on-board
computer.
f Please consult your authorized Porsche
dealer.
f Use only tires approved by Porsche.
The available items in the tire pressure menu
depend on the equipment of your vehicle. For this
reason it is possible that some of the items shown
here are not available on your on-board
computer’s display.
f Make sure that tire pressures correspond to
the on-board computer settings. Correct the
tire pressure if necessary.
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on Page 277. Tire pressure warnings
The tire pressure warning light on the instrument
panel and a corresponding message on the on-
board computer warn about loss of pressure in
two stages, depending on the amount of pressure
loss.
Driving with insufficient tire pressure reduces the
road safety of the vehicle
and destroys the tire and
wheel.
Stage 1 – Add air
The pressure in the tire is too low by 4 to 7 psi (0.3
to 0.5 bar).
f The tire pressure warning contains the
affected tire with the tire pressure to be added.
Correct the tire pressure at the next
opportunity.

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.

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 tempo-
rarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on re-
maining fuel is impossible.

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.

“Sport Plus” mode activated:
In “Sport Plus” mode, the PDK transmission
changes to a shift program designed for driving
on race circuits. 7th gear is not selected.
The gear-changing performance is enhanced
significantly again compared with “Sport” mode.
fPlease see the chapter “SPORT MODE” on
Page 61.
Driving with Launch Control
Driving with Launch Control allows you to achieve
maximum acceleration from a standing start. It is
intended to provide you with a unique enjoyment of
your vehicle under controlled circumstances and
is not intended to be used in any location where it
could be a nuisance to other persons.
Warning!
There is a risk of endangering other road
users if you use this Control in an improper
location or in a situation where other persons
might need to take evas ive action due to the
rapid acceleration that this technology
permits.
f Launch Control is designed to be used in a
controlled environment on closed circuit
driving courses where no vehicle cross traffic
or pedestrian traffic is present.
f Use Launch Control only if conditions permit it
to be applied in a safe manner. f
Do not use Launch Control if there is a possibi-
lity it could endanger other persons. Such a
possibility exists if you cannot see that you
have a clear road with no possibility of cross
traffic in your intended direction of driving. Caution!
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off. Use of
Launch Control will inevitably reduce the life
of the engaged engine and transmission
components.
Preconditions:
– Launch Control should only be used when the engine has reached operating temperature.
– “Sport Plus” mode must be switched on (light- emitting diode in button is on and “SPORT
PLUS” is displayed on the on-board computer).
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully (kickdown activated) and hold.
The engine speed will flatten out at around
6500 rpm.
“Launch Control active” is displayed on the
on-board computer. 3. Release the brake within a few seconds.
Remaining stationary for a long time with
“Launch Control active” can lead to overload-
ing of the transmission.
In order to protect the transmission, the engine
power is then reduced an d the “Launch Control
active” process is cancelled.
Shifting gears on the steering wheel
With the shift buttons on the steering wheel, you
can change temporarily fr om automatic selection
mode D to manual mode M.
For example:
– Shifting down before bends and on entering built-up areas.
– Shifting down on downward slopes (engine braking).
– Shifting down for brief spurts of acceleration.
Manual selection mode remains engaged:
– for cornering (depending on the lateral acceler- ation) and overrunning,
– when the vehicle is stationary (e.g. at a junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds (unless cornering or overrunning),
– after driving off.
