Tire PressureThe tire pressure monitoring system continuously
monitors tire pressure and tire temperature on all
four wheels and warns the driver when the tire
pressure is too low.
The display as well as the settings for tire
pressure monitoring are done on the multi-
purpose display in the TYRE PRESSURE menu.
However the tire pressure must be set manually
on the wheel.
The tire pressures to be monitored for tire type
are permanently set in the tire pressure
monitoring system and cannot be changed.
The driver is solely responsible for filling the tires
correctly and for selecting in the multi-purpose dis-
play.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure in-
creases increases risk of a tire failure and re-
sulting loss of control. Furthermore, low tire
pressure increases rate of wear of the affect-
ed tires.
fWhen a flat tire has been displayed, immediate-
ly stop in a suitable place and check the tires
for damage. If necessary remedy the damages
with a tire sealant.
fDo not by any means continue to drive with
leaking tires.
fDefective tires must be immediately replaced
by a specialist workshop.
Tyre repairs are not permissible under
any circumstances.
fSealing the tyre with the tyre sealant is only an
emergency repair, so you can drive to the next
workshop. The maximum permitted speed is
50 mph (80 km/h).
fDo not drive with tires whose tyre pressure
drops again in a short period of time. In cases
of doubt, have tires checked by a specialist
workshop.
fIf the tire pressure monitoring system is defec-
tive (e.g., defective wheel transmitter), contact
a specialist workshop immediately and have
the damages repaired.
The tire pressure will not be monitored by a
defective tire pressure monitoring system.fUse only the pressure differences shown in the
TYRE PRESSURE menu or from tyre pressure
messages or warnings when correcting the
tyre pressure.
fTires lose air over time without a tire defect be-
ing present. A tire pressure warning will then
appear in the multi-purpose display
Correct the tire pressure.
fThe tire pressure monitoring system gives a
warning about tyre damages due to insufficient
tyre pressure as well as about a gradual loss
of pressure due to foreign objects.
The tyre pressure monitoring system cannot
warn you about tyre damages occurring sud-
denly (e.g., flat tyre due to sudden external ef-
fects).
fIf a message is displayed, check the tire
pressure at the next opportunity.
fBefore fitting tires approved by Porsche which
are not stored in the on-board computer, the
missing information should be supplemented
in the on-board computer.

Shifting Gear, Traction Systems
Porsche Traction Management (PTM)Porsche Traction Management is a full-time all-
wheel control system designed to influence the
longitudinal and lateral dynamics. It is closely
linked with the Porsche Stability Management
(PSM) system:
PTM ensures the best possible power distribution
to the four driven wheels at the front and rear ax-
les. The system realises this optimal traction by in-
tervening in the lock control function of the trans-
fer case and rear differential. PTM is active at all
times and, unlike the PSM, cannot be switched off.Advantages of PTM
– Obvious improvement in traction, driving stabil-
ity and steering ability of the car.
– Vehicle is more manageable when driven at its
performance limits.
– Improved straight-ahead tracking and stability.
– The aforementioned features allow for a sport-
ier setup of the running gear.
– The TCS and ABD provide even better traction
for all wheels.
Caution!
In spite of the advantages of PTM, it is still the driv-
er’s responsibility to adapt his driving style and
maneuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PTM.
Risks of accident due to inappropriate speed
cannot be reduced by PTM.

Full-time all-wheel drive
With the four-wheel drive, the drive power is vari-
ably distributed to the front and rear wheels.
Power distribution and wheel speed compensation
between the front and rear axles is realised with a
transfer box.
Distribution of the drive power depends on the
wheel speed difference between the two axles.
The transfer box always controls power distribu-
tion in such a way that optimal propulsion is
achieved, even on an unfavorable road surface.
Full-time four-wheel drive ensures optimal handling
and great stability.
Caution!
In spite of the advantages of four-wheel drive, 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 in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with four-wheel drive.
Risks of accident due to inappropriate speed can-
not be reduced by four-wheel drive.Automatic brake differential (ABD)
The ABD system controls the front and rear axles
separately. If one wheel of an axle starts to spin,
it is braked so that the other wheel on the same
axle can be driven.
The ABD recognises different driving states, and it
features control strategies adapted to these
states. In situations in which little propulsive power
is required, such as when the car moves off on a
level gravel surface, traction control already be-
comes active at low engine speeds. If great
propulsive power is required, e.g. when moving off
on an uphill slope or for rapid acceleration, the
ABD is adapted accordingly.
A special off-road program is used in Low Range
mode.Traction control system (TCS)
The traction control system prevents the wheels
from spinning by adjusting the engine power,
thereby ensuring good lane-holding ability and a
stable driving behavior.

Practical Tips, Minor Repairs
Snow chains
Caution!
Risk of damage to body, axle or brake com-
ponents.
fUse only the fine-link snow chains recommend-
ed and authorized by Porsche so that sufficient
clearance between the wheel well and the
chain is assured.
fFollow instructions issued by the supplier of the chains.
The best possible handling characteristics are
achieved when snow chains are fitted on all four
wheels of the vehicle. However, it is also possible
to fit snow chains on only one axle (preferably the
rear axle).
fBefore fitting chains, remove accumulated ice
and snow from the wheel well.
fVehicles with snow chains must not be driven
faster than 30 mph (50 km/h).Different states and countries have varying statu-
tory requirements regarding maximum speed.
fCheck with local authorities for possible re-
strictions.
fRemove chains as soon as the roads are free
of ice and snow.

Practical Tips, Minor Repairs
TowingCertain state statutes and local ordinances prohib-
it towing with a chain, rope or even a tow bar. In
addition, damage to your vehicle may result from
improper procedures. Consult your authorized
Porsche dealer for details.Vehicle towingFlat bed towing is the preferred type of towing to
be used on Porsche vehicles. Under certain cir-
cumstances, wheel lifts may be used when the ve-
hicle will not roll.
The vehicle must be towed with all four
wheels off the ground, otherwise damage to
the vehicle may result.Towing hookThe towing hook is contained in the tool kit.
Caution!
Risk of damage to the vehicle.
fUse the towing hook only for an emergency to
remove the vehicle off the road. The towing
hook is to be used only to pull the vehicle onto
the flat bed, tractor or towing aparatus if the
vehicle will roll freely. Under no circumstances
is the vehicle to be secured using the towing
hook.fNever use the towing hook to tow this or any
other vehicle.
Front and rear mounting
1. Carefully lever out the appropriate plastic cov-
er A in the bumper with the blade of a screw-
driver.
The cover is captive and need not be removed
completely.
2. Screw in towing hook B as far as the stop (left-
hand thread) and tighten hand-tight.

1).
The best possible handling characteristics are achieved when snow chains are fitted on all four wheels of the
vehicle. However, it is also possible to fit snow chains on only one axle (preferably the rear axle).
For safety reasons, vehicles with snow chains must not be driven faster than 30 mph (50 km/h).
fObserve the respective road traffic regulations.
fUse only Porsche-authorized fine-link cross-type or edge chains.
