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.

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withdrawn.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.

Driving and Driving Safety The corner is taken in the right gear, and when you
accelerate out of the corner you do not have to
change down.
Shifting gear on the steering wheel
By shifting gear with the rocker switches on the
steering wheel, you can temporarily change from
automatic selection mode D to manual selection
mode M.
Advantages:
– Shifting down before corners and on entering
congested areas, on downward slopes (engine
braking) or for brief spurts of acceleration.
– Selecting 1st or 2nd gear for moving off.
The manual selection mode remains engaged:
– For cornering (depending on the lateral
acceleration) and passing,
– When the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– automatically after around 8 seconds
(unless car is cornering, passing or
stationary),
– if you depress the accelerator to kickdown.Temporary change-down
Precondition:
– Speed is higher than approx. 33 mph
(54 km/h).
fDepress accelerator quickly.
The Tiptronic changes temporarily to the
sportiest gear-changing map, i.e. to the
highest possible gear-changing points.
Correspondingly, the transmission shifts down
immediately by one, two or three gears.
Ending the function
fRelease the accelerator markedly (by approx.
25%).
Kickdown
The kickdown function is active in selector lever
position D.
fFor optimum acceleration, e.g. when over-
taking, depress the accelerator pedal beyond
the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
full-throttle position.
D - Automatic selection mode (in the off-
road driving program)fUse selector lever position D for “normal”
driving.
The gears are shifted automatically according
to the accelerator position and speed.
The gear-changing points have been adjusted to
achieve the best possible vehicle control on diffi-
cult terrain.
Depending on the route profile, the gear-changing
points are shifted towards higher or lower engine-
speed ranges. On steep downhill stretches,
upward shifts are prevented until medium engine
speeds are reached (at least 2,500 rpm).
When the car is passing, an automatic upshift
does not occur when the engine speed limit is
reached.
Shifting gear on the steering wheel
By shifting gear with the rocker switches on the
steering wheel, you can temporarily change from
automatic selection mode D to manual selection
mode M.
Advantages:
– Shifting down on downward slopes (engine
braking) or for brief spurts of acceleration.
– Selecting 1st/2nd or 3rd gear for moving off.

The manual selection mode remains engaged:
– For passing
– Depending on lateral acceleration
– When the vehicle is stationary (e.g. at a
junction).
The system leaves manual selection mode:
– Automatically after around 8 seconds
(unless car is subject to high lateral accelera-
tion, is passing or stationary),
– if you depress the accelerator to kickdown.
Kickdown
The kickdown function is active in selector lever
position D.
fFor optimum acceleration, e.g. when overta-
king, depress the accelerator pedal beyond
the full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed.
Upward shifts occur at the highest possible engine
speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
full-throttle position.
Tip on driving
Unlike in the on-road driving program, an automa-
tic upshift is not performed in manual selection
mode M when the engine-speed limit is reached.
M - Manual selection mode (in the on-
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).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.
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
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.

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.
Limp-home modeIf there is a fault in the transmission:
–An X appears instead of the current gear
indicator on the multi-purpose display of the
instrument panel.
The transmission no longer shifts.
fTo remedy the fault, immediately consult an
authorized 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.
