System learning phaseEach time a wheel is changed, the tire pressure
monitoring system re-learns the tires. The system
identifies the wheel positions.
The current tire pressures will not be available on
the multi-purpose display until the learning phase
is complete.
System learning phase
fSelect tire type and tire size in the menu TYRE
PRESSURE > SETTINGS > TYRES.
The learning process is started. The tire type
and size m ust b e sele cte d even if the se tting s
for the new set of wheels are the same as for
the old wheels.Note
The spare wheel and collapsible spare wheel do
not contain a wheel transmitter and are not
monitored by the tire pressure monitoring system.
The tire pressures for cold tires (68 °F/20 °C) are
shown in the TYRE PRESSURE menu (filling infor-
mation) during the learning phase. The required
pressure for the spare wheel is always displayed
in the TYRE PRESSURE menu (filling information).
fCheck the tire pressure for the spare wheel
and collapsible spare wheel manually.
Tire pressure menuMAIN MENU > TYRE PRESSURE
The TYRE PRESSURE menu provides an overview
of the current pressure specifications for the
respective wheel (filling information). The pressure
differences with respect to the required pressure
are specified.
If the wheels have not been learned, the current
pressures are unavailable.
The spare wheel is not monitored. The required
pressure is specified in brackets.
To make changes to the settings of the tire pres-
sure monitoring system, select SETTINGS in the
TYRE PRESSURE menu.

– In case of sealing-set operation, the menu
changes directly to the basic screen. All
settings are retained.
– If the vehicle is operated with a collapsible
spare wheel or spare wheel, the warning mes-
sage “SYSTEM NOT ACTIVE, WORKSHOP” is
initially displayed for 10 seconds. The system
then returns to the basic screen.
No:
The display automatically returns to the menu
TYRE PRESSURE > SETTINGS.
fSet the mounted tire set with tire type and tire
size. The system will re-learn the tires.
No monitoringIn the event of faults the tire pressure monitoring
cannot monitor the tire pressure.
The warning light on the instrument panel and a
message on the multi-purpose display light up.
Monitoring is not active when:
– the tire pressure monitoring system is faulty,
– wheel transmitters for the tire pressure
monitoring system are not present,
– temporarily after changing a wheel,
– has detected too many wheel transmitters,
– there is external interference by other radio
sources, e.g., wireless headphones,
– tire temperatures are too high.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 108.fAll warnings and messages in the tire pressure
monitoring system are also indicated by the
warning light in the instrument panel.
The warning light goes out as soon as all faults
are remedied.

Warning – Flat tire – Check tires Stop in a suitable place and check the tires. Change wheel if
necessary.
Check spare wheel – Required pressure:
50 psi/3.4 barAppears about every 6 months.
Check if the pressure of the mounted spare wheel matches the
required pressure, as it is not monitored electronically.
Tire pressure too low – Add air System detects a pressure loss of at least 2.9 psi. (0.2 bar).
Correct tire pressure at the next opportunity.

max. 50 mph (80 km/h) Observe maximum permitted speed.
Collapsible spare wheel 51 psi/3.5 bar
max. 50 mph (80 km/h) Information on driving with a collapsible spare wheel.
Observe maximum speed of max 50 mph or 80 km/h and
required pressure of 51 psi or 3.5 bar.
System not activeIndication when spare wheel or collapsible spare wheel is used
or tire pressure monitoring system is faulty.
Consult a qualified specialist workshop.
Select new set of wheels in the Tire pressure menu after
changing the wheels.
System not active – Brief disturbanceExternal interference (e.g., wireless headphones) or excessive
temperature (over 248 °F/120 °C) at the wheel transmitters.
Tire pressure monitoring system will reactivate itself.
System not active –
Too many wheel transmittersTire pressure monitoring system detects more than 4 wheel
transmitters (winter wheels in in the luggage compartment,
for example).
System will reactivate itself.
No monitoring – System learning After the tire type and size are selected in the tire pressure
menu, the system re-learns the tires.

Front ultrasound sensorsSensors
Six ultrasound sensors in the front and rear
bumpers measure the distance to the closest ob-
stacle.
– Range of outer sensors
(front and rear):
approx. 24 in. (60 cm)
– Range of front middle sensors (arrow):
approx. 48 in. (120 cm)
Rear ultrasound sensors– Range of rear middle sensors (arrow)
(only in vehicles without spare wheel bracket):
approx. 59 in. (150 cm)
– Range of rear middle sensors
(only in vehicles with spare wheel bracket):
approx. 48 in. (120 cm)
Obstacles cannot be detected in the "blind" sensor
area (above and below the sensors).Maintenance note
fThe sensors must always be kept free of dust,
ice and snow in order to ensure that they are
fully functional.
fDo not damage sensors by abrasion or
scratching.
fMaintain sufficient distance when cleaning with
steam-jet units.
The sensors will be damaged if the pressure is
too high.
Note on operation
The rear ultrasound sensors may not function
correctly if tires that have not been recommended
by Porsche are fitted on the spare wheel bracket.
If the spare wheel bracket is open, this may impair
the function of the rear ultrasound sensors.
In vehicles that have air suspension with level
control and height adjustment, the system may
not recognise obstacles near the ground at terrain
level or special terrain level.

Loading InformationDefinitionsThe towing capacity (gross weight of the trailer)
is the sum of the trailer's empty weight and the
weight of the load.
The vertical coupling load is the weight that the
trailer drawbar exerts on the trailer coupling of the
vehicle.
The rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load
and the vertical coupling load of the trailer.
The gross weight of the vehicle and trailer is
the sum of the weight of the towing vehicle and the
weight of the trailer.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, emergency tools, and spare tire
assembly. This weight does not include passen-
gers and cargo.
The Gross Vehicle Weight is sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the maxi-
mum total weight of vehicle, passengers, lug-
gage, hitch, trailer tongue load and optional equip-
ment.The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This infor-
mation is located on the safety comliance sticker
located in the driver’s side door jamb.
For determining the compatibility of the tire and
vehicle load capabilities:
fPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 358.
The load capacity coefficient (e.g. “106”) is a mi-
nimum requirement.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers, cargo and trailer.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This informa-
tion can be found on the tire pressure plate.
If a trailer is being towed, the trailer tongue weight
must be included as part of the cargo load.
The maximum loaded vehicle weight is the
sum of curb weight, accessory weight, vehicle ca-
pacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for
a tire at the maximum permissble inflation pres-
sure.The cargo capacity is the permissible weight of
cargo, the substracted weight of passengers from
the load limit.
fNever exceed the permissible limits.
Danger!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
fPersons must ride only on the seats provided
for this purpose.
fMake sure that everybody fastens their safety
belts.
Risk of personal injury, loss of control and
damage to vehicle.
fNever exceed the specified axle loads. Over-
loading can shorten the service life of the tires
and car, as well as lead to dangerous vehicle
reactions and long braking distances. Damage
due to overloading is not covered by the vehic-le warranty.
