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
M - Manual selection mode (in the off-
road driving program)
Warning!
The kickdown function is not active in manual
selection mode “M”.
The kickdown function cannot be used to
downshift in manual selection mode “M”.
fTherefore shift down manually when accelera-ting (e.g. to overtake).
Tip on driving
The kickdown function is not active in selector
lever position M.
Unlike in the road driving program, an automatic
upshift is not performed when the engine-speed
limit is reached.Shifting up
fPress upper part (+) of a rocker switch A or
fPush selector lever B forward in the M gate.
Shifting down
fPress lower part (–) of a rocker switch A or
fPush selector lever B back in the M gate.
Depending on driving speed and engine speed,
you can shift up or down at any time. Gear
changes which would exceed the upper or lower
engine-speed limit are not executed by the control
unit.
You can change down two gears by quickly pres-
sing rocker switches A or selector lever B twice.
The gear is changed down automatically just
before idle speed is reached.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
If manual mode fails, the control electronics
switch to automatic mode. In this event, the instru-
ment panel will display selector lever position D.
fTo remedy the fault, please consult an
authorized Porsche dealer.
StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
fDo not hold the car on a slope using the acce-
lerator. Use the brake pedal or the parking
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Tip on driving
In selector lever positions D and M, the hillholder
function makes it easier to move off from a stand-
still on an upward slope when the engine is run-
ning. The driver does not have to apply the brake.

ABS
(Anti-lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt her/his driving style
and maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed can-
not be reduced by ABS.
ABS ensures:
–Full steering control
The vehicle remains steerable
–Good driving stability
No skidding due to locked wheels
–Optimum braking distance
Shorter stopping distances in most cases
–Lock prevention
No flat spots on the tiresFunction
The decisive advantage of ABS is in the driving
stability and maneuvrability of the vehicle in
hazardous situations.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable to
extremely rapid cadence braking.
The pulsating brake pedal and a “rattling noise”
warn the driver to adapt her/his driving speed to
the road conditions.
fIf full braking should be necessary, press the
brake pedal all the way down throughout the
entire braking procedure, regardless of the
pulsating pedal. Do not ease up on pressure
applied to the pedal.

Warning light
If the ABS warning lights light up in the instrument
panel and on the multi-purpose display of the
instrument panel while the engine is running, the
ABS has switched off because of a fault.
In this event, the braking system will operate with-
out lock prevention,as in cars without ABS.
fAdapt your driving style to the changed
braking behavior.
fThe ABS must be checked immediately at an
authorized Porsche dealer. This is necessary
in order to prevent the occurrence of further
faults whose effects cannot be defined.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing the ABS to
switch off.
Off-road ABS
(ABS in Low Range program)
When Low Range is active, an ABS specially
matched to off-road driving is activated automati-
cally.In the event of braking on loose ground, the per-
missible slip values for ABS braking are increased
so that the off-road braking distance is reduced
(wheels dig into the surface).
If the driver needs to steer, this off-road driving
program is automatically switched off to maintain
steerability.
Hillholder -
moving-off assistant on vehicles with
Tiptronic SIn Tiptronic selector lever positions D and M, the
hillholder function makes it easier to move off
from a standstill on an upward slope when the
engine is running. The driver does not have to
apply the brake.
The hillholder thus makes moving off on slopes
easier.
Danger!
Risk of accident, resulting in serious perso-
nal injury or death.
The vehicle can roll backwards if the Hillhol-
der is switched off.
fAlways apply the footbrake on slopes.Hillholder is not active:
– In Tiptronic selector lever positions N and R
– In the limp-home mode and
– If not all of the wheels are touching the ground
(on difficult terrain, for example).
Warning!
In spite of the advantages of the hillholder func-
tion, it is still the driver’s responsibility to adapt
her/his driving style and maneuvers in line with
situational conditions.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with the hillholder function.
Driving at the limits should be avoided, e.g., on icy
slopes or on slippery surfaces. In this and similar
cases, the support of the hillholder function is not
guaranteed.

Driving and Driving Safety
Air Suspension with Level Control
and Height AdjustmentOn vehicles with air suspension, the driver can set
five different level steps manually.
The preselected level is automatically adjusted to
suit the vehicle speed.
The height of the car is automatically kept
constant when the vehicle is loaded.
Tip on driving
It is not permissible to drive on public roads with
the car in the terrain or special terrain setting.Note on operation
Frequent level changes can cause the compressor
to overheat. In this case, the compressor must
cool for several minutes before level adjustment is
fully functional again.
Normal levelThe ground clearance at normal level is around
8.5 in. (215 mm) (Cayenne, Cayenne S,
Cayenne S Transsyberia) or 7.68 in (195 mm)
(Cayenne GTS).Terrain levelThis setting is intended for off-road driving, field
paths and forest paths, etc.
The vehicle is raised by around 1 in. (26 mm)
compared to normal level.
Terrain level can be selected only manually at
speeds below around 50 mph (80 km/h).
The car is automatically lowered to normal level at
speeds exceeding around 50 mph (80 km/h).
The car is automatically raised to terrain level
when Low Range is activated.
Special terrain levelThis setting is intended only for extremely
challenging terrain requiring maximum ground
clearance. The vehicle is raised by around 2.2 in.
(56 mm) compared to normal level.
The warning light in the instrument panel
comes up when the special terrain level has been
reached.
Special terrain level can be selected only at
speeds below around 19 mph (30 km/h).
The car is automatically lowered to terrain level at
speeds exceeding approx. 19 mph (30 km/h).Low levelThis level is intended for high-speed driving. Above
speeds of around 78 mph (125 km/h), the car is
automatically lowered by around 1 in. (24 mm)
(Cayenne, Cayenne S, Cayenne S Transsyberia) or
0.4 in. (9 mm) (Cayenne GTS) compared to
normal level.
When the speed drops to below around 25 mph
(40 km/h), the car is automatically raised to
normal level.
Note
If low level was set manually with the rocker switch
in the center console, low level also remains
active at speeds below around 25 mph (40 km/h).
