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):

Multi-Purpose Display and Instruments – in the sub-menu TYRE PRESSURE (filling infor-
mation):
as a required pressure for each axle if Tire
Pressure Monitoring has not yet been taught
the corresponding values,
– in the front left door aperture for each wheel,
– in the Technical Data chapter in this Owner’s
Manual: Please see the chapter “TIRE
PRESSURES, COLD (68 °F/20 °C)” on
Page 354.
If Tire Pressure Monitoring has been taught the
corresponding values, the deviations from the
required pressure are shown in the sub-menu
TYRE PRESSURE (filling information) indepen-
dently of the tire temperature. The correct tire
pressure adjustment can be made for a wheel on
the basis of this display information even if the
tires are warm.
Insufficient tire filling pressure can cause tires to
overheat when driving and thus be damaged –
even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.
fFor this reason, always make sure that the tire
pressure is correct.

ABS
(Anti-lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt her/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 physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed can-
not 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 distances in most cases
–Lock prevention
No flat spots on the tiresFunction
The decisive advantage of ABS is in the driving
stability and maneuvrability of the vehicle in
hazardous situations.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable to
extremely rapid cadence braking.
The pulsating brake pedal and a “rattling noise”
warn the driver to adapt her/his driving speed to
the road conditions.
fIf full braking should be necessary, press the
brake pedal all the way down throughout the
entire braking procedure, regardless of the
pulsating pedal. Do not ease up on pressure
applied to the pedal.

Driving and Driving Safety
Driving systems for off-road drivingSpecially adapted driving programs or power-
transmission and running-gear control systems
are available for off-road driving:
– Off-road program Low Range
–Off-road PSM
–Off-road ABS
– Center differential lock
– Rear differential lock
fPlease see the chapter “POWER-TRANSMISSI-
ON AND RUNNING-GEAR CONTROL SYSTEMS”
on Page 181.Before driving offTires
fCheck tread depth and tire pressure.
fCheck for damage and remove any foreign
objects (e.g. stones) from the tread.
fReplace missing valve caps.
Rims
fReplace dented or damaged rims before
driving off road.
Vehicles with SportDesign package
Caution!
Risk of damage. On vehicles with Sport-
Design package, front, rear, and side
member trim are painted. Off-road driving
can seriously damage these trim parts.
fWhen driving off-road, make sure these parts
are not damaged.
fMake sure there is sufficient clearance
between obstacles and the underside of the
vehicle.
fAvoid driving through water.
fDo not use side member trims or rear wheel spoilers as a running board.
After driving off roadOff-road driving places a greater burden on the
vehicle than does normal driving on roads.
We recommend inspecting the vehicle after off-
road driving. Potential damage poses an accident
risk and impairs driving comfort. Damage on the
car is recognized in good time if the car is
checked.
Caution!
Car damage poses an accident risk for the
vehicle occupants and other road users.
fIn cases of doubt, have your vehicle checked
by your authorized Porsche dealer.
fExamine tires for signs of damage such as
cuts, tears, bulges or foreign objects stuck in
the tread.
Replace a damaged tire if necessary.
fHave any damage to your vehicle repaired by an authorized Porsche dealer without delay.

Trailer Hitch
231
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
maximum total weight of vehicle, passengers,
luggage, hitch, trailer tongue load and optional
equipment.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 see the chapter “TIRES, RIMS, TRACKS”
on Page 350.
The load capacity coefficient (e.g. “106”) is a
minimum requirement. For more information:
fPlease see the chapter “INSCRIPTION ON
RADIAL TIRE” on Page 290.
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
capacity 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 permissible inflation pres-
sure.
The cargo capacity is the permissible weight of
cargo, the subtracted 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 loss of control, damage to the vehicle
and serious personal injury or death.
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 vehicle warranty.
