Off-Road DrivingPlease read this chapter carefully before driving
off road with your Porsche.
The information provided will familiarise you with
the special advantages of your vehicle, allowing
you to arrive at your destination safely every time.
We recommend practicing on less rugged terrain.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.Maintenance Note
Please bear in mind that off-road driving subjects
all vehicle components to considerably more wear
than normal use, making professional inspection
and maintenance after each use a vital precondi-
tion for functioning and safety.
Grains of sand, dirt particles and other abrasive
materials entering the brakes can cause exces-
sive wear or unpredictable braking action.
Rules for off-road drivingfEnsure vehicle is equipped with approved all-
terrain tires.
fPay attention to the ground clearance of the
vehicle.
Please see the chapter “GROUND
CLEARANCE” on Page 357.
fActivate Low Range.
Please see the chapter “SELECTING OFF-
ROAD DRIVING PROGRAM” on Page 178.
fStow or fasten luggage and loads securely.
Please see the chapter “LOADING
INFORMATION” on Page 231.
fIf unknown terrain is obscured from view,
examine it on foot first and traverse it with
extreme caution.
This way, obstacles are easier to recognize
and damage to the vehicle is avoided.fAlways drive with the engine running.
Power steering assistance is provided only
with the engine running.
fDrive slowly and uniformly.
fAlways make sure that the wheels touch the
ground.
fBefore driving through water, check the water
depth, the condition of the surface beneath it
and the speed of the water.
fLook out for obstacles such as boulders,
holes, tree stumps or ruts.
fAlways keep the sliding/lifting roof or
Panorama roof system and the side windows
closed while driving.
fDo not depart from marked routes or paths.
fRespect Nature.
Always obey off-limits signs.

Recommended procedure
fDeactivate the Low Range off-road driving
program.
fClean headlights and tail lights and check them
for signs of damage.
fClean the front and rear lincense plates.
fClean the tire tread with a jet of water and
remove any foreign objects.
fClean wheels, wheel housings and the under-
body with a jet of water.
fCheck whether the car has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
fAfter off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.fAfter driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake discs, brake
pads, wheels and axle joints and have them
cleaned.
fIf you experience severe vibrations after
driving off road, check the wheels for foreign
substances.
These substances can produce an imbalance
which might be responsible for the vibrations.
Removing these deposits may remedy the
problem.
Uphill driving
Danger!
Danger of serious personal injury or death
and risk of damage if the vehicle should
overturn.
fDo not turn around when driving uphill.
fIf it is not possible to climb a gradient, the car
must be backed down in reverse gear.
fDo not drive over embankments or slopes at
steep diagonal angles.
fIf the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
fWhen driving uphill, never let the vehicle roll
backward when in idle or not in gear.
Exclusive use of the footbrake is too risky in such situations.

Crossing obstacles
Caution!
Risk of damage to the underbody and chas-
sis components if obstacles are traversed
improperly.
fAlways bear in mind the ground clearance of
your vehicle.
fSlowly drive over the middle of tree trunks,
boulders or other obstacles with one of the
front wheels.
fCross the obstacle with the rear wheel in the same way.
Note on operation
fActivate Low Range and engage differential
locks if necessary.Tips on driving
fHave your passenger direct you if necessary.
fAvoid high engine speeds (max. 2,500 rpm).
fDrive slowly.
Driving on sandNote on operation
fActivate Low Range and engage differential
locks if necessary.
Tips on driving
Loose sand is an especially tricky surface for off-
road driving.
You can often become stuck in sand within
minutes if you do not drive correctly in such
situations.
fDrive at brisk pace and do not stop under any
circumstances. This will reduce the chance of
the car becoming bogged down.
fFollow existing tracks – provided that they
have not been covered by blown sand, are not
too deep and the car's ground clearance is
sufficient.
Pay attention to the ground clearance of the
car.
Please see the chapter “GROUND
CLEARANCE” on Page 357.
fAvoid high engine speeds (max. 2,500 rpm).

Car Audio Operation/TipsFor radio operation see your radio manual
which is included with your on-board litera-
ture.FM receptionA vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely
normal for a given reception area, and they do not
indicate any problem with the radio itself.
Note
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and
approved by Porsche may impair radio reception.Fading and drifting
FM range is limited to about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving away from the desired
station's transmitter, the signal will tend to fade
and/or drift. This condition is more prevalent with
FM than AM, and is often accompanied by
distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by
adjusting the tone control for greater bass
response until the disturbance has passed.Multipath
Because of the reflecting characteristics of FM, di-
rect and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception.
Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.10_Cayenne_21_KW17.book Seite 218 Donnerstag, 9. April 2009 3:33 15

Driving with a trailer
When towing a trailer you must under all circum-
stances adapt your speed to prevailing road and
driving conditions. Towing at excessive speed can
result in loss of control. Observe country-specific
laws for driving with trailers.
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.
fAlways see the permissible towing capacity,
vertical coupling load and rear-axle load.
Please see the chapter “WEIGHTS” on
Page 356.
Maintenance Note
fPlease take into consideration that driving with
a trailer places markedly greater stress on all
vehicle components. Expert inspection and
maintenance after every use are indispensable
prerequisites for proper functioning and safety.

Parking AidsParkAssist 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.
Tiptronic 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
area.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
engaged.
Warning!
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
parking and when assessing obstacles.
fMake sure that no persons especially small
children, animals or obstacles are within the maneuvering area.
Switching ParkAssist on and offfSwitch 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
obstacle 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 vehic-
les with trailer coupling: approx. 14 in. (35 cm)).
The second red light segment lights up.
If the obstacle is approached even closer, the
system 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
adjusted to your own requirements at your
authorized 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.
