Selecting “Comfort pressure” in the
Tire pressure menu
Available setting options:
–“Comfort ”
–“ Standard ” For speeds up to 100 mph (160 km/h), the tire
pressures can be reduced to increase driving
comfort.
The Tire Pressure Monitoring system must be set
to the applicable tire pressure (comfort pressure
or standard pressure).
If you selected “
Comfort press.”, the TPM
system automatically uses lower pressure values
when monitoring tire pressures.
The comfort tire pressures are included in the
technical data or under “Fill info” in the Tire
pressure menu, you can compare the pressure
differences (e.g. 4.4 psi (+0.3 bar)) with the
“Comfort pressures”.
For tires that have not ye t been learned, the new
required tire pressures are displayed instead of
the actual tire pressures.
For information on learning the tires:
f Please see the chapter “SYSTEM LEARNING”
on page 134.
Caution!
Tires are inflated to comfort pressure at the
factory, which is not suitable for driving at
very high speeds. Comfort pressure speed warning
If the maximum speed of the preset comfort
pressure is exceeded, a warning message
appears on the multi-function display.
Warning!
Risk of accident when exceeding the
maximum speed.
Driving at excessive speeds when the comfort
pressure is active will destroy the tires.
f Never exceed the speed specified on the
warning message.
f Always set the standard tire pressure when driving at higher speeds.

Ye l l o w a r n i n g – I n f l a t e !Tire pressure warnings
The tire pressure warning light on the instrument
panel and a corresponding message on the multi-
function display warn about loss of pressure in two
stages (yellow and red), depending on the amount
of pressure loss.
Yellow warning – Inflate
The pressure in the tire is too low by more than
4to7psi (0.3 to 0.5 bar ).
The tire pressure warning specifies the affected
tire and the target tire pressure.
Correct the tire pressure at the next opportunity. This tire pressure warning appears:
– for approx. 10 seconds when the vehicle is
stationary and the ignition is switched off or
– when the ignition is switched on again.
The warning can be acknowledged when the
ignition is switched on.
The tire pressure warning light on the instrument
panel goes out when the tire pressure has been
corrected.
Red warning – Tire pressure!Red warning – Tire pressure!
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 6 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.

134
Instrument Panel and Multi-Function Display
If necessary, fill in ti
re 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.
System learningTire Pressure Monitoring begins to “learn” the
wheels after a wheel change, wheel transmitter
replacement or update of the tire settings . During
this process, Tire Pressu re Monitoring recognizes
the wheels and their locations.
The following message appears on the multi-
function display (example):
“No monitoring, system is learning”.
The wheel learning process takes place
exclusively when the vehicle is being driven
(vehicle speed above 16 mph (25 km/h)).
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 multi-function display:
– The tire pressure warning light remains lit until all wheels have been learned.
– Lines (-.-) appear on the display of the “Tire pressure” function. – The required pressures for cold tires (68 °F
(20 °C)) are indicated under “Fill info” in the tire
pressure menu.
Position and pressure information is displayed as
soon as Tire Pressure Monitoring has assigned
the wheels recognized as belonging to the vehicle
to the correct wheel positions.
f Check the tire pressure for all wheels under
“Fill info ”.
f Correct the tire pressure to the required
pressure if necessary.
Changing a wheel and replacing tiresfNew wheels must be fitted with radio
transmitters for Tire Pressure Monitoring.
Before tires are changed, the battery charge
condition of the wheel transmitters should be
checked.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
f Switch off the ignition when changing a wheel.
The tire settings on the mu lti-function display must
be updated after changing a wheel.
If the tire settings are not updated, the message
“Tire change? Update settings!” is displayed on the
multi-function display.
f Update the multi-function display settings the
next time the vehicle is stationary.
Pressure increase as the result of
temperature increaseIn accordance with physical principles, the tire
pressure changes as the temperature
changes.The tire pressure increases or decreases
by 0.1 bar (1.5 psi) for
every 18 °F (10 °C) change in temperature.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 “Restricted monitoring” appears
on the multi-function display.
– No tire pressures are displayed on the multi-function display for wheels with faulty
wheel transmitters.

No monitoringIn the event of faults, Tire Pressure Monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel lights up
and a corresponding message appears on the
multi-function display.
Monitoring is not active:
– if Tire Pressure Monitoring is faulty,
– if wheel transmitters for 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,
– if more than four wheel transmitters are recognized,
– if there is external interference by other radio sources, e.g. wireless headphones,
– if tire temperatures are too high.

Driving and Driving Safety

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA
