“Flat tyre” warningThe warning threshold for output of this warning
message is speed-dependent.
At a speed of below 100 mph (160 km/h), this
warning indicates a pressure loss of at least 7 psi
(0.5 bar); at a speed of above 100 mph
(160 km/h), the warning indicates a pressure loss
of at least 6 psi (0.4 bar). The message indicates
the wheel in which the pressure loss has been
detected. The deviation from the required
pressure is displayed for the corresponding
wheel. The tire pressure warning light on the
speedometer lights up in addition to the warning
message. This significant pressure loss is a
danger to road safety.
fThe warning message can be acknowledged
while driving.
To do this, press the ENTER button on the
wiper stalk. The tire pressure warning light on
the speedometer remains lit.
The measure display SELECTION AFTER
WARNING appears only after the ignition is
switched back on again.
The display shows: SELECTION AFTER WARNING1. Stop the vehicle immediately in a suitable
place.
2. Check the indicated wheel for damage.
3. Fill the tire or change the wheel, as appro-
priate.
- Adding air
Example: If the tire pressure display shows
“–7 psi (---0.5 bar)”, you must increase the tire
pressure by 7 psi (0.5 bar).

Multi-Purpose Display and Instruments The spare wheel and collapsible spare wheel are
not equipped with wheel transmitters and are not
monitored by Tire Pressure Monitoring.
Wheel change (without warning)The settings of the multi-purpose display must be
updated after changing wheels or tires on the
vehicle.
Please see the chapter “SETTING THE TIRE TYPE
AND SIZE” on Page 134.Setting spare wheel/sealant (without
warning)If you have fitted a spare wheel or collapsible
spare wheel or used tire sealant without being
requested to do so by a “Flat tyre” warning on the
multi-purpose display, you must subsequently
update the settings in the TYRE PRESSURE sub-
menu.Setting spare wheel.
The spare wheel is not equipped with a wheel
transmitter and is not monitored by Tire Pressure
Monitoring. The tire pressure warning light on the
speedometer flashes about 60 seconds and lights
up thereafter permanently when the ENTER button
is pressed. The value “_” is displayed in the sub-
menu TYRE PRESSURE (filling information) at the
position of the spare wheel.

Note on operation
The reminder SPARE WHEEL/SEALING SET
OPERATION? goes out automatically after approx.
10 seconds if no selection is made during this
time. The original selection “YES” is then
maintained.In the event of faults, Tire Pressure Monitoring
cannot monitor the tire pressure. A distinction is
made between partial monitoring and inactive
system.
In the case of partial monitoring, the tire pressure
warning light on the speedometer flashes about
60 seconds and lights up thereafter permanently.
No message is output on the multi-purpose
display.
If Tire Pressure Monitoring is not active, the tire
pressure warning light on the speedometer
flashes about 60 seconds and lights up thereafter
permanently. A corresponding message is output
on the multi-purpose display.
The warning light goes out as soon as all faults
have been remedied.
Tire Pressure Monitoring switches to partial
monitoring if:
– there are up to two wheel transmitters not
present or faulty (e.g. a spare wheel or collap-
sible spare wheel is fitted that does not have a
wheel transmitter).
In the event of partial monitoring, the value “_” is
displayed in the sub-menu TYRE PRESSURE (filling
information) at the position of the faulty or missing
wheel transmitter.
Tire Pressure Monitoring is not active in the
following cases:
– Tire Pressure Monitoring is faulty,– at least three wheel transmitters for Tire
Pressure Monitoring are faulty or not present,
– temporarily after changing a wheel,
– too many wheel transmitters have been
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.

purpose display:
Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.
Notes on tire pressurePressure increase as the result of tempera-
ture increase
In accordance with physical principles, the tire
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.
Tire pressure specifications
The tire pressure must match the prescribed value
(required pressure).
You can find information on the tire pressure for
cold tires 68 °F (20 °C):

Driving and Driving Safety
Tiptronic SThe Porsche Tiptronic is a six-speed transmission
and features an “automatic” and a “manual” gear-
shift mode.
In automatic selection mode (selector lever po-
sition D), gear changing is automatic.
Depending on the driving program, you can
change temporarily from automatic to manual
mode using the rocker switches on the steering
wheel.
In manual selection mode (selector lever
position M), you change gear using the rocker
switches on the steering wheel or by pushing the
selector lever forward or back.
The functions of selector lever positions D and M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
You can change between selector lever positions
D and M as you wish while driving.
The currently selected gear is retained if you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Note on operation
Take care not to operate the rocker switches on
the steering wheel inadvertently, thereby trigger-
ing undesired gear changes.
Changing the selector lever positionThe selector lever is locked with the ignition key
withdrawn.
The selector lever can be moved from position P
or N only with:
– The ignition switched on
– The brake pedal pressed and
– The release button pressed (arrow).Release button
The release button (arrow) on the front side of the
selector lever prevents unintentional gear chan-
ges.
The release button must be pressed when shifting
to position R or P.
The selector lever cannot be operated in the event
of an electrical fault.
fPlease see the chapter “SELECTOR LEVER
EMERGENCY RELEASE” on Page 175.
StartingThe engine can be started only in selector lever
position P or N with the brake pedal pressed.Moving offfSelect the desired position for moving off
(D, M or R) only when the engine is idling and
when depressing the brake pedal.
fSince the car creeps when in gear, do not re-
lease the brake until you want to move off.
fAfter selecting a gear, do not accelerate until
you can feel that the gear is engaged.

Selector lever positionIndicator for selector lever position and
engaged gearWhen the engine is running, the selector lever
position and engaged gear are indicated.
Selector Lever PositionsP – Parking lockIn selector lever position P, the driven wheels are
mechanically locked.
fEngage parking lock only when vehicle is
stationary.
fEngage parking lock after applying the
parking brake and release it before releasing
the parking brake.
fAlways apply the parking brake before leaving
the vehicle.
The ignition key can be withdrawn only in selector
lever position P.R – ReversefSelect reverse only if car is stationary and the
brake is applied.N – NeutralSelector lever position N must be selected for
towing or in car washes, for example.
fSelect the desired position for moving off
(D, M or R) only when the engine is idling and
when depressing the brake pedal.
D - Automatic selection mode (in the road
driving program)fUse selector lever position D for “normal”
driving.
The gears are shifted automatically according
to the accelerator position and speed.
Depending on the way the vehicle is driven and on
the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges. Movement of the accelerator,
driving speed, longitudinal and lateral acceleration
and the road profile all have an influence on the
gear-changing characteristic.
When PSM is switched off, transmission gear
changes are done at higher engine speeds.
Unwanted upward shifts, e.g. before corners, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on corners are not made until the engine-
speed limit is reached.
During braking, and depending on the amount of
deceleration, the Tiptronic changes down earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the corner.
