tion to the driver of the distance between the
vehicle and a large obstacle.
ParkAssist is switched on automatically when the
engine is started and remains active up to a speed
of approx. 9 mph (14 km/h).
ParkAssist is switched off automatically at high
speed. ParkAssist is switched on again auto-
matically when the speed drops below approx.
9 mph (14 km/h).
The selector lever position determines activation
levels for ParkAssist and the corresponding area
that is monitored.
Selector lever position:
–P – ParkAssist is not activated.
–R, N – ParkAssist is activated for the front and
rear areas.
–D, M – ParkAssist is activated for the front ar-
ea.
Danger!

B- Front display – right monitoring areaWarning indicators, signal tones, distances
The warning indicator for the front area is located
on the dashboard.
The warning indicator for the rear area is located
in the rooflining at the rear of the loadspace.
The warning indicators for the various monitoring
areas (left and right) are subdivided respectively
into one green, 4 yellow and 2 red light segments.
C- Rear display – right monitoring area
D- Rear display – left monitoring areaIf ParkAssist is activated, the green light seg-
ments of the active warning indicators are lit up
continuously.
If the vehicle approaches an obstacle that has
been detected by the sensors, one or more of the
yellow or red light segments lights up, depending
on the distance to the obstacle.If the first yellow light segment lights up, the ob-
stacle is still 48 in. or 120 cm (to the front) or
48 in. to 59 in. or 120 to 150 cm (to the rear)
away.
A brief signal tone sounds when reversing.
Anintermittent tone sounds when the distance
becomes less than approx. 24 in. or 60 cm. The
fourth yellow light segment lights up.
Acontinuous tone sounds when the distance be-
comes less than approx. 10 in. or 25 cm (on vehi-
cles with trailer coupling: approx. 14 in. or
35 cm). The second red light segment lights
up.
If the obstacle is approached even closer, the sys-
tem may not be able to recognize the obstacle any
longer.
fSet the radio volume so that the signal tones
are not drowned out.
You can have the volume of the signal tones ad-
justed to your own requirements at your autho-
rized Porsche dealer.
Note on operation
If the obstacle is approached even closer after the
continuous tone sounds and the second red light
segment lights up, the system may not be able to
recognize the obstacle any longer.

Controls, Safety, Instruments Limits of ultrasonic measurement
– ParkAssist cannot detect sound-absorbing ob-
stacles (e.g. powder snow),
– Sound-reflecting obstacles (e.g. glass surfac-
es, flat painted surfaces),
– And very thin obstacles.
Other ultrasound sources (e.g. pneumatic brakes
of other vehicles, jackhammers) can interfere with
detection of obstacles.
Fault indication without warning tone
All red light segments of the active warning indica-
tors light up when there is a temporary fault in
ParkAssist.
Note
Correct operation is no longer ensured if there is
a temporary fault (e.g. caused by ice formation or
heavy soiling on the sensors).
The system detects the temporary fault.
All light segments light up until a speed of
9 mph (14 km/h) is reached.
ParkAssist is ready for operation again when the
interference has been eliminated.Fault indication with warning tone
In the event of a long-lasting fault in ParkAssist,
the red light segments of the active warning indi-
cators light up and a continuous tone sounds for
three seconds after a transmission range has
been selected.
Possible causes
– Defect or system fault.

Car Telephone and Aftermarket Alarms Important legal and safety information re-
garding the use of cellular telephones
Some states may prohibit the use of cellular tele-
phones while driving a vehicle. Check the laws and
regulations on the use of cellular telephones in the
areas where you drive.
Danger!
Risk of an accident.
Severe personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious personal injury or
death.
When using your cellular telephone, you should al-
ways:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held tele-phone.It is essential to observe the instructions of
the telephone manufacturer before putting
the telephone into operation.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e“ symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
He is familiar with the technical requirements for
installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can cre-
ate a discharged battery or excessive current
draw from added equipment.If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfer-
ence caused by buildings, landscape and weather
is unavoidable. It may become particularly difficult
to hear when using the hands-free function due to
external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.

Towing a trailer
Warning!
Driving with a trailer
fAlways observe the permissible towing capac-
ity, vertical coupling load and rear-axle load.
Please observe the chapter “WEIGHTS” on
Page 352.
fWhen connected, the trailer must always be
horizontal behind the towing vehicle. If neces-
sary, use a trailer with an adjustable drawbar.
fWhen the vehicle is driven in the mountains, the
engine output decreases as altitude increases.
The maximum weights stated are the values at
sea level. The total weight of the car-trailer
combination must therefore be reduced by
10% for each increment of 3,280 ft. or
1,000 metres altitude. A fractional increment
counts as the full 1,000 metres. Please take
this into consideration when planning your
route.Distributing the load
fDistribute the load in the trailer so that heavy
objects are as close to the axle as possible.
Always safeguard all objects against slipping
and tie them down securely.
fYou should make the best possible use of the
trailer coupling's rated vertical coupling load
when loading the trailer, but never exceed it.
Tire pressure
fSelect the vehicle tire pressure for full load
when towing a trailer.
fPlease observe the chapter “Tire pressure ta-
bles”.
fCheck the tire pressure of the trailer's wheels
according to the manufacturer's instructions.Door mirrors
fIf the width of the trailer obstructs your view of
the traffic behind the trailer, you must have ad-
ditional door mirrors fitted.
Headlights, lights
fCheck whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.

Shifting Gear, Traction Systems Indication of a fault by:
– Continuous illumination of the light-emitting
diode in the button
– Illumination of the warning light on the
instrument panel
– A message on the multi-purpose display of the
instrument panel
fAdapt your driving behavior to the changed
conditions.
Drive slowly to the nearest authorized Porsche
delaer and have the fault remedied.
fPlease observe the chapter “WARNING LIGHTS
AND WARNING MESSAGES” on Page 106.
Changing from off-road driving program
to on-road driving programfReduce speed to below 19 mph (30 km / h) or
stop vehicle.
fMove selector lever to position N.
fPull rocker switch A back in stages until light-
emitting diodes B, C and if necessary, D are
out.
The Low Range indicator light on the instru-
ment panel and light-emitting diode B beside
the rocker switch flash several times during
the shifting process.
High Range is active.
Danger!
Serious risk of injury or death. Risk of
accident due to uncontrolled vehicle
movement. The selector lever is blocked
during the shifting procedure. Shifting when
driving uphill can cause the vehicle to stand
still or even roll backwards, if the shifting
procedure has not yet been completed.
When driving downhill, the vehicle can accel-
erate unintentionally while shifting.
fIncreased brake readiness is required.
fPlease observe the chapter “POWER-TRANS-
MISSION AND RUNNING-GEAR CONTROL SYS-
TEMS” on Page 211.

The events below inform the driver of PSM control
operations and warn him to adapt his driving style
to the road conditions:
– The information light in the instrument panel
lights up.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as the PSM controls the
brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
However, it is possible at any time to achieve
full vehicle deceleration by increasing the foot
pressure slightly.
Examples of PSM control operations
–Vehicle understeers:
If the front wheels of the vehicle drift on a
bend, engine power is reduced and the rear
wheel on the inside of the bend is braked if
necessary.
–Vehicle oversteers:
If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.Combined use of PSM and PTM/PTM Plus
In order to ensure optimal stabilisation of the
vehicle, the center differential lock (PTM) and
possibly the rear differential lock (PTM Plus) are
also opened when PSM interventions occur.
Tip on driving
When PSM is switched off, wheel-specific brake
interventions and the traction control system
(TCS) are also inactive.
The automatic brake differential (ABD) remains on.Off-road PSM
(PSM in Low Range program)
When Low Range is active, an off-road PSM
specially matched to off-road driving is activated
to enhance traction.
At a speed below 22 mph (35 km/h), the terrain
PSM intervenes later if the vehicle should under-
steer and thereby improves steerability in Low
Range.
If the brakes are highly stressed, the automatic
brake differential (ABD) switches itself off to
protect the brakes. It remains deactivated until the
brake system has cooled sufficiently.
Engine drag torque control
In conditions of excessive slip, the engine drag
torque control system prevents all driven wheels
from locking up when the car is overrunning. This
is also the case for downshifts on a slippery road.
