Note on operation
If the Low Range indicator light next to the rocker
switch flashes rapidly after the ignition is swit-
ched on, there is a fault in the shifting system.
fHave the vehicle checked immediately.
Please consult an authorized Porsche dealer.
If the Low Range indicator light next to the rocker
switch flashes when you attempt to operate
rocker switch, then at least one condition for shif-
ting has not been met:
Vehicles with manual transmission
– Vehicle is not stationary.
– Brake is not pressed.
– Gearshift lever in not in neutral.
Vehicles with Tiptronic S
– Vehicle has exceeded or gone below the limit
speed.
– Tiptronic selector lever is not in position N.
Sport ModeFunction
The sports exhaust system is switched on and a
sportier car set-up is obtained when Sport mode
is switched on.
Interventions by the Porsche control systems are
intentionally shifted towards greater agility and
driving performance.
– PASM (Porsche Active Suspension Manage-
ment) is automatically changed to Sport mode,
resulting in a stiffer suspension setup.– PDCC (Porsche Dynamic Chassis Control) is
automatically set to Sport mode, and this
further reduces the roll tendency of the
vehicle.
– The air suspension automatically changes to
the low level setting.
– The Tiptronic S transmission changes to a
sportier shift strategy.
The gear-changing points are shifted to higher
speed ranges. Upward shifts are initiated later,
and deceleration shifts are performed earlier.
The vehicle moves off in 1st gear.
– The electronic accelerator pedal reacts
sooner, and the engine is more responsive to
throttle inputs.
– Sporty engine tuning is activated.

Please see the chapter “PORSCHE ACTIVE
SUSPENSION MANAGEMENT (PASM)” on
Page 193.

Driving and Driving 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 see the chapter “TRAILER COUPLING”
on Page 230.
Danger!
Risk of accident, resulting in serious perso-
nal injury or death.
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 func-
tion:
– By shifting to neutral.
– When changing gears.
– If the engine is not running.
Danger!
Risk of accident, resulting in serious perso-
nal injury or death.
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.
If road grip is lost on one or more wheels, the
system brakes the wheels which have good road
contact.
The braking ability of the Engine Braking Support
is affected by slippery surfaces (e.g., on icy or
loose surfaces), like all brakes.
Warning!
Risk of accident, resulting in serious perso-
nal injury or death. Reduced braking ability
on a slippery surface.
fAlways adjust your driving style to the driving situation.
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 Tiptronic 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.
Tip on driving
The Porsche Down-Hill Assistant is active when
driving downhill either forwards or backwards.
Checks on test standsBrake 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 Tiptronic selector lever in position N or the
gearshift lever in neutral.Balancing wheels on the vehicle
During finish balancing of the wheels, the entire
vehicle 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
involving the use of two-wheel dynamometer.
A two-wheeled dynamometer is a treadmill type
device upon which a single axle of the car, the dri-
ving 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
d a m a g e t o t h e p o w e r t r a i n c a n re s u l t i f t e s t e d o n a
two-wheel dynamometer.
Warning!
To avoid severe powertrain damage and a
possible unexpected movement of the vehic-
le.
fYour Porsche Cayenne vehicle must never be
tested on a two-wheel dynamometer.
fAdvise the emission station of this warning before testing the vehicle.

Parking
237
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.
