Parking AidsParkAssistParkAssist provides a visual and acoustic indica-
tion to the driver of the distance between the
vehicle and a large obstacle.
ParkAssist is switched on automatically when the
ignition is switched on 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.Gearshift lever position:
–R – ParkAssist is activated for the front and
rear areas.
–In all other gearshift positions – ParkAssist
is activated for the front area.
Note
On vehicles with manual transmission, the parking
assistant is not switched on in the rear area if the
vehicle rolls backward without reverse gear en-
gaged.
Danger!
Risk of serious personal injury or death.
ParkAssist cannot detect small objects such
as children and pets.
Even when using ParkAssist, the driver is still
responsible for taking due care when park-
ing and when assessing obstacles.
fMake sure that no persons especially small
children, animals or obstacles are within the maneuvering area.Switching ParkAssist on and off
fSwitch ParkAssist on and off using button A in
the roof console.
When ParkAssist is switched off, the indicator
light in the button lights up.
Note on operation
It is a good idea to switch off ParkAssist when
driving off-road and on unpaved surfaces.

A- Front display – left monitoring area
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. (120 cm) (to the front) or 48 in.
to 59 in. (120 to 150 cm) (to the rear) away.
A brief signal tone sounds when reversing.
An intermittent tone sounds when the distance
becomes less than approx. 24 in. (60 cm). The
fourth yellow light segment lights up.
A continuous tone sounds when the distance be-
comes less than approx. 10 in. (25 cm) (on vehi-
cles with trailer coupling: approx. 14 in. (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 author-
ized 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
9mph (14km/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.
fSwitch ParkAssist off.
When ParkAssist is switched off, the indicator
light in the button lights up.
fPlease have the fault remedied at an author-
ized Porsche dealer.Driving with a trailer
The ParkAssist rear monitoring area is switched
off when the trailer’s power supply is plugged in.

Driving with a trailer
When towing a trailer you must under all circum-
stances adapt your speed to prevailing road and
driving conditions. Never exeed a speed of
50 mph (80 km/h). Towing at excessive speed
can result in loss of control.
fCarefully and gradually familiarize yourself with
the handling and braking behavior of the car-
trailer combination.
fDo not drive with the towing vehicle empty and
the trailer loaded.
If this unfavorable combination is unavoidable,
please drive especially slowly.
fBear in mind the different vehicle handling and
size in situations such as braking, parking,
cornering and overtaking, etc.
fThe driving stability of the car-trailer combina-
tion worsens as the speed increases. There-
fore, drive especially slowly on downhill
stretches and in the case of unfavorable road
and weather conditions (such as wind).
fDrive in an appropriately low gear on downhill
stretches in order to make use of the engine
braking effect.fSlow down immediately if the trailer starts to
sway. Do not countersteer; brake if necessary.
Never attempt to straighten out the car-trailer
combination by accelerating.
fActivate Low Range when moving off on steep
slopes.
fUnder no circumstances may people, animals
or objects be in the space between the trailer
and the towing vehicle when the vehicle is
moving.
fWhen reversing, bear in mind that ParkAssist is
not active.
Maintenance note
Please take into consideration that driving with a
trailer places markedly greater stress on all vehi-
cle components. Expert inspection and mainte-
nance after every use are indispensable prerequi-
sites for proper functioning and safety.

Porsche Drive-Off Assistant –
Moving-off assistant on vehicles with
manual transmissionThe Porsche Drive-Off Assistant enables the driver
to move off on upward slopes. The vehicle must
have sufficient road contact to use this feature.
The Porsche Drive-Off Assistant is available for
slopes starting at approximately 5%.
fPlease observe the chapter “TRAILER
COUPLING” on Page 212.
Danger!
Risk of accident.
When moving off on a slippery surface (e.g.,
on icy or loose surfaces), assistance by the
Porsche Drive-Off Assistant is no longer
assured. In this case, the vehicle could slip.
The limits set by the physics of driving cannot
be overcome, even with the Porsche Drive-
Off Assistant. The responsibility for moving
off on upward slopes is still the driver's,
despite the Porsche Drive-Off Assistant.
fAlways adjust your driving style to the driving
conditions and vehicle load, use the footbrake if necessary.Moving off with Porsche Drive-Off Assistant
1. Hold the vehicle securely with footbrake or
parking brake on the slope.
The engine must be running.
2. Fully depress the clutch pedal.
3. Engage one of the gears used to ascend in the
direction of travel (1st gear or reverse).
4. While keeping the clutch pedal depressed,
release the footbrake or foot-operated parking
brake.
The vehicle is held on the slope.
5. Move off as usual.Note on operation
The Porsche Drive-Off Assistant ceases to
function:
– by shifting to neutral.
– when changing gears.
– by stopping or “stalling” the engine.
Danger!
Risk of accident.
If the Porsche Drive-Off Assistant ceases to
function, the vehicle will no longer be held on
a slope.
fHold the vehicle with the footbrake.

Engine Braking Support
(Assistance when heading downhill)The Porsche Down-Hill Assistant is an assistance
system which helps the driver at slower downhill
driving up to approx. 12 mph (20 km/h), e.g., on
steep slopes or on wintry mountain roads.
As long as the gas pedal is not used when
traveling downhill, the Porsche Down-Hill Assistant
is active and brakes the vehicle.
The braking ability of the Engine Braking Support
is affected by slippery surfaces (e.g., on icy or
loose surfaces), like all brakes.
If road grip is lost on one or more wheels, the
system brakes the wheels which have good road
contact.
Conditions:
– The gas pedal must not be used when
travelling downhill.
– The speed must not exceed 12 mph
(20 km/h).
–Vehicles with Tiptronic S:
The selector lever position D, M or R must be
engaged.
–Vehicles with manual transmission:
The reverse gear or any other gear (1. - 6. )
must be engaged. The clutch pedal must not
be used when travelling downhill.
Warning!
Risk of accident. Reduced braking ability on
a slippery surface.
fAlways adjust your driving style to the driving situation.
Tip on driving
The Porsche Down-Hill Assistant is active when
driving downhill either forwards or backwards.
Checks on test standsPower measurement
Power measurements on roller test stands are not
approved by Porsche.
Brake tests
Brake tests must be carried out only in High Range
and on plate-type test stands or roller test stands.
The following limit values must not be exceeded
on roller test stands:
– Testing speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds
Parking brake test
Parking brake tests on the brake tester must be
performed only with the ignition switched off and
the selector lever in position N or the gearshift le-
ver in neutral.Balancing wheels on the vehicle
During finish balancing of the wheels, the entire ve-
hicle must be lifted and the wheels must be free to
turn.
Dynamometer testing procedure Some U.S. states and Canadian provinces con-
duct emissions inspection/maintenance testing in-
volving the use of two-wheel dynamometer.
A two-wheeled dynamometer is a treadmill type
device upon which a single axle of the car, the driv-
ing axle of the vehicle, rotates to simulate vehicle
operation on the road while the vehicle remains
stationary.
Your Porsche Cayenne has a full-time four-wheel
drive system which cannot be disabled. Severe
damage to the powertrain can result if tested on a
two-wheel dynamometer.
Warning!
To avoid severe powertrain damage and a
possible unexpected movement of the vehi-
cle.
fYour Porsche Cayenne vehicle must never be
tested on a two-wheel dynamometer.
fAdvise the emission station of this warning be-fore testing the vehicle.

Maintenance, Car Care

High-pressure cleaning units
Warning!
High-pressure cleaning units can damage
the following components:
–Tires
– Logos, emblems
– Painted surfaces
– Widened fenders
– Lock and latch of the removable towing attach-
ment
– Seals of the electrically retractable ball hitch
– Alternator, valve covers
– ParkAssist sensors
fPlease observe the operating instructions from
the unit manufacturer.
fAlways cover the lid over the brake fluid reser-
voir prior to cleaning. Never point the cleaning
jet directly at the lid.
fWhen cleaning with a flat-jet nozzle or the like,
maintain a minimum distance of 21 in.
(50 cm).fNever use high-pressure cleaning units with a
round-jet nozzle.
A high-pressure cleaning unit with round nozzle
will damage your vehicle. The tires are particu-
larly susceptible to damage.
fDo not point the cleaning jet directly at any of
the aforementioned components.
WashingThe best protection for the car from the damaging
effects of the environment is frequent washing and
preservation. The underside of the car should also
be thoroughly washed for cinders, salt or sanding
at winter‘s end.
The longer salt, road dust, industrial dust, insect
remains, bird excrement, and tree exudations (res-
in, pollen), etc. are allowed to remain on the body-
work, the more serious is their harmful effect.
New cars should be washed carefully with plenty
of clear water to protect the new paint work.
Dark paint finishes show up the smallest of sur-
face damage (e.g. scratches) more readily than
lighter colors.
Dark colors are also more susceptible to scratch-
ing because of the composition of their pigments
and require particularly careful paint care.fDo not wash your car in bright sunlight or while
the bodywork is still hot.
fWhen washing by hand, use abundant water, a
soft sponge or wash brush and Porsche car
shampoo.
fBegin by spraying the body thoroughly with wa-
ter to rinse away loose dirt.
fAfter washing, rinse the car with plenty of wa-
ter and then dry with a chamois leather.
Do not use the same chamois leather for dry-
ing as you use for cleaning the windshield and
windows.
Warning!
Moisture which gets on the brakes during a
car wash can reduce braking efficiency or
make the brake pull unevenly which could in-
crease the danger of an accident, causing
serious personal injuries or death.
fAlways apply the brakes a few times after
washing the car to test braking efficiency and
dry the brake discs.
When doing this, take care not to hamper other
road users behind you (traffic conditions per-mitting).
