DeceleratingOption 1
fPush operating lever down into position 4 until
the desired speed is reached.
The speed reached is maintained and stored
when the operating lever is released.
Option 2
fPush operating lever slightly downwards into
position 4 (a maximum of 10 times).
The speed is reduced by 1 mph (2 km/h), each
time the lever is pushed downwards.
Interrupting cruise control operationThe speed driven before the interruption remains
stored in the memory and can be reactivated by
operating the operating lever. Please see the
chapter “RESUMING THE STORED SPEED” on
Page 168.
fPush the operating lever forward to position 2
(it doesn’t engage) or
fOperate brake or clutch pedal or, on vehicles
with Tiptronic S, select position N.
fPlease see the chapter “TIPTRONIC S” on
Page 170.
Cruise control operation is interrupted
automatically:
– If the set vehicle speed is exceeded by more
than approx. 16 mph (25 km/h) for longer than
20 seconds.
– If the actual vehicle speed falls by approx.
6 mph (10 km/h) below the set vehicle speed
for longer than 5 seconds (e.g. upward
slopes).
– If Porsche Stability Management (PSM)
intervenes for longer than 0.2 seconds.
– If Low Range is switched on.
Resuming the stored speedfPull back the operating lever to position 1.
Note on operation
The stored speed should only be recalled when
traffic conditions and the road surface so permit.Switching cruise control readiness offfPush forward the operating lever to position 2
until it clicks audibly into place.
The memory is cleared and the green
readiness light goes out.
When the vehicle is parked and the ignition
switched off, the memory is cleared.
Tip on driving
On upward or downward slopes, the set speed
cannot always be maintained by cruise control.
fTo obtain sufficient engine braking or a better
engine-speed range, therefore, you have to
change down to a lower gear.

Risk of accident, resulting in serious perso-
nal injury or death.
fDo not obstruct the pedal travel with floor mats
or other objects.To avoid damage to the clutch and transmis-
sion:
fAlways depress the clutch pedal fully when
changing gears. Make sure that the gearshift
lever is completely engaged.
fOnly shift into reverse when the car has come
to a complete stop
Floor mats of the correct size and with the
appropriate fasteners are available from your
authorized Porsche dealer.
The positions of the gears are shown on the shift
diagram on the gearshift lever.
fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the reversing lights are lit.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the tacho-
meter, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permit-ted engine speed when down-shifting.

Driving and Driving Safety
Tiptronic SThe Porsche Tiptronic is a six-speed transmission
and features an “automatic” and a “manual” gear-
shift mode.
In automatic selection mode (selector lever po-
sition D), gear changing is automatic.
Depending on the driving program, you can
change temporarily from automatic to manual
mode using the rocker switches on the steering
wheel.
In manual selection mode (selector lever
position M), you change gear using the rocker
switches on the steering wheel or by pushing the
selector lever forward or back.
The functions of selector lever positions D and M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
You can change between selector lever positions
D and M as you wish while driving.
The currently selected gear is retained if you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Note on operation
Take care not to operate the rocker switches on
the steering wheel inadvertently, thereby trigger-
ing undesired gear changes.
Changing the selector lever positionThe selector lever is locked with the ignition key
withdrawn.
The selector lever can be moved from position P
or N only with:
– The ignition switched on
– The brake pedal pressed and
– The release button pressed (arrow).Release button
The release button (arrow) on the front side of the
selector lever prevents unintentional gear chan-
ges.
The release button must be pressed when shifting
to position R or P.
The selector lever cannot be operated in the event
of an electrical fault.
fPlease see the chapter “SELECTOR LEVER
EMERGENCY RELEASE” on Page 175.
StartingThe engine can be started only in selector lever
position P or N with the brake pedal pressed.Moving offfSelect the desired position for moving off
(D, M or R) only when the engine is idling and
when depressing the brake pedal.
fSince the car creeps when in gear, do not re-
lease the brake until you want to move off.
fAfter selecting a gear, do not accelerate until
you can feel that the gear is engaged.

Selector lever positionIndicator for selector lever position and
engaged gearWhen the engine is running, the selector lever
position and engaged gear are indicated.
Selector Lever PositionsP – Parking lockIn selector lever position P, the driven wheels are
mechanically locked.
fEngage parking lock only when vehicle is
stationary.
fEngage parking lock after applying the
parking brake and release it before releasing
the parking brake.
fAlways apply the parking brake before leaving
the vehicle.
The ignition key can be withdrawn only in selector
lever position P.R – ReversefSelect reverse only if car is stationary and the
brake is applied.N – NeutralSelector lever position N must be selected for
towing or in car washes, for example.
fSelect the desired position for moving off
(D, M or R) only when the engine is idling and
when depressing the brake pedal.
D - Automatic selection mode (in the road
driving program)fUse selector lever position D for “normal”
driving.
The gears are shifted automatically according
to the accelerator position and speed.
Depending on the way the vehicle is driven and on
the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges. Movement of the accelerator,
driving speed, longitudinal and lateral acceleration
and the road profile all have an influence on the
gear-changing characteristic.
When PSM is switched off, transmission gear
changes are done at higher engine speeds.
Unwanted upward shifts, e.g. before corners, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on corners are not made until the engine-
speed limit is reached.
During braking, and depending on the amount of
deceleration, the Tiptronic changes down earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the corner.

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.

Switching off PSMfPress PSM OFF button A.
PSM is switched off after a short delay.
The light-emitting diode in the button is lit up.
When the PSM is switched off, the multifunctio-
nal PSM light on the instrument panel is lit and
a message appears in the multi-purpose dis-
play of the instrument panel.During braking, the vehicle is stabilized even
when PSM is switched off.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
PSM should always be switched on during
“normal” driving.
However, it can be of advantage to switch off PSM
temporarily in exceptional situations:
– On a loose surface or in deep snow
– When “rocking the vehicle free”
– When using snow chains.
Vehicles with Tiptronic: When the PSM is
switched off the slip monitoring function is also
deactivated.– The multifunctional light on the instrument pa-
nel lights up for a lamp check when the ignition
is switched on.
– The light indicates a control operation, inclu-
ding when PSM is switched off (brake control
in the event of one-sided wheel spin).
– In conjunction with the multi-purpose display on
the instrument panel, the light indicates that
PSM is switched off.
– Faults are displayed by the light in conjunction
with the multi-purpose display of the instru-
ment panel.
PSM is out of order.

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.
