M - Manual selection mode (in the on-
road driving program)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.
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.
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 accelerat-ing (e.g. to overtake).
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 chang-
es 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 press-
ing rocker switches A or selector lever B twice.
If PSM is active and the engine-speed limit is
reached, an automatic upward shift is performed
or, just before idling speed is reached, a down-
ward shift is performed.
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 instrument panel will display se-
lector lever position D.

StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
fDo not hold the car on a slope using the accel-
erator. 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
prevents the car from rolling backward when it has
been stopped on an upward slope with the engine
running.
fPlease observe the chapter “HILLHOLDER” on
Page 242.
ParkingfGo easy on the accelerator.
fWhen parking or maneuvring in a small space,
control the speed by careful use of the foot-
brake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode M. This prevents
the occurrence of gear changes that could cause
wheelspin.
Reduced driving programIf there is a fault in the transmission:
–An X appears instead of the current gear
indicator on the multi-purpose display of the in-
strument panel.
The transmission no longer shifts.
fTo remedy the fault, immediately consult an au-
thorized Porsche dealer.
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program.
Damage to the vehicle may result as well as
loss of control, if the vehicle is moving for-
ward fast enough to cause rear wheel lockup.
fDo not shift into R while the vehicle is moving forward.
Tip on driving
3rd or 5th gear in selector position D and reverse
gear R are now available and will allow you to
reach the nearest authorized Porsche dealer.
fPlease go to your authorized Porsche dealer
as soon as possible.

Driving Programs for On-Road and
Off-Road DrivingTwo different driving programs with special power-
transmission and running-gear control systems
(such as ABS, off-road ABS and PSM, etc.) are pro-
vided in your Porsche, with the aim of realising the
best possible driving dynamics combined with
maximum safety.
All control systems meet these requirements for
both off-road and normal driving.With rocker switch A, you can easily select the ap-
propriate driving program to suit the special re-
quirements for the respective terrain.
Off-road program Low Range
(with reduction)
When Low Range is active, the power transmis-
sion and running-gear control systems are
automatically adapted to the requirements for
off-road driving.
On-road driving program High Range
(without reduction)
When High Range is active, the power-transmis-
sion and running-gear control systems are auto-
matically adapted to the requirements for on-road
driving.
UseRocker switch A is located in the center console
of the vehicle. It features a multi-step function and
can be operated in both directions. Each time the rocker switch is pushed forward,
the vehicle becomes one step more suitable for
off-road driving. This is realised by changing from
the on-road to the off-road driving program or by
engaging the differential locks in stages.
The number of differential locks that can be en-
gaged in Low Range depends on the equipment of
your vehicle.
Each time the rocker switch is pushed back, the
vehicle becomes one step more suitable for on-
road driving.
Once the driving program has been selected, the
rocker switch springs back to home position.
Notes on operation
If the Low Range indicator light beside the rocker
switch flashes rapidly after the ignition is
switched on, there is a fault in the shifting
system.
fPlease have the vehicle checked immediately
at an authorized Porsche dealer.

Shifting Gear, Traction Systems If the Low Range indicator light beside the rocker
switch flashes when you attempt to operate rock-
er switch, the conditions for a shift have not been
met:
Vehicles with manual transmission
– Vehicle is not stationary.
– Brake is not pressed.
– Gear-shift lever is not in neutral.
Vehicles with Tiptronic S
– Vehicle has exceeded or gone below the limit
speed.
– Selector lever is not in position N.

the off-road driving program is indicated on the
multi-purpose display of the instrument panel
and by illumination of light-emitting diodeB.
The Low Range indicator lights in the instru-
ment panel and beside the rocker switch flash
several times during the shifting process.
Low Range is now engaged.
Caution!
Risk of engine damage (overrevving). In the
Low Range program, the gear-changing
points are shifted towards lower engine-
speed ranges.
fShift early to prevent overrevving the engine.
Tip on driving
When Low Range is active, the power
transmission and running-gear control systems
are automatically adapted to the requirements for
off-road driving.

Vehicles with Tiptronic S
fReduce speed to below 9.3 mph (15 km / h) or
stop vehicle.
fMove selector lever to position N.
fPush rocker switch A forward until activation of
the off-road driving program is indicated on the
multi-purpose display of the instrument panel
and by illumination of light-emitting diodeB.
The Low Range indicator light on the instru-
ment panel and light-emitting diode B beside
the rocker switch flash several times during
the shifting process.
Low Range is now engaged.
Danger!
Serious risk of injury or death. Risk of
accident due to uncontrolled vehicle
movement. The selector lever is blocked
during the shifting procedure. Shifting when
driving uphill can cause the vehicle to stand
still or even roll backwards, if the shifting
procedure has not yet been completed.
When driving downhill, the vehicle can accel-
erate unintentionally while shifting.
fIncreased brake readiness is required.
fPlease observe the chapter “POWER-TRANS-
MISSION AND RUNNING-GEAR CONTROL SYS-
TEMS” on Page 235.

B- Low Range is engaged
C- Center differential lock is fully engagedFully engaging the center differential lock
in Low RangeTip on driving
When the center differential lock is fully engaged,
there is no longer any speed difference between
the front and rear axles. If, for example, both
wheels at the front axle lose traction on an icy
road or soft surface, the rigidly linked drive wheels
will permit the vehicle to continue moving never-
theless.fPush rocker switch A forwards in stages until
engagement of the center differential lock is in-
dicated on the multi-purpose display of the in-
strument panel and by the illumination of the
two light-emitting diodes B and C.
The center differential lock is changed over to
fully engaged state by the automatic control
system.

When the rear differential lock is fully engaged,
there is no longer any speed difference between
the two rear wheels. If, for example, one drive
wheel at the rear axle loses traction on an icy road
or soft surface, the stiff through-drive function will
permit the car to continue moving nevertheless.fPush rocker switch A forwards in stages until
engagement of the rear differential lock (trans-
verse lock) is indicated on the multi-purpose
display of the instrument panel and by the
illumination of the three light-emitting diodes B,
C and D.
The center and rear differential locks are
changed over to fully engaged state by the au-
tomatic control system.
Note on operation
The rear differential lock can only be engaged
while the engine is running.
Hydraulically disengageable anti-roll barsThe front and rear anti-roll bars can be disengaged
to improve traction and comfort when driving off
road. This feature increases the wheel articulation.
Condition for disengaging the anti-roll bars
– Low Range is engaged.
Note
The anti-roll bars cannot be engaged if the wheel
articulation or lateral acceleration is too great.
