Tiptronic SThe Porsche Tiptronic is a five-speed transmission
with an “automatic” and a “manual” selection
mode.
In automatic selection mode (selector lever po-
sition D), gear changing is automatic.
You can change temporarily from automatic to
manual mode using the rocker switches on the
steering wheel.
In manual selection mode (selector lever posi-
tion M), you change gear using the rocker switch-
es on the steering wheel.
You can change between selector lever position D
and M as you wish while driving.
Note
Take care not to operate the rocker switches on
the steering wheel inadvertently in either auto mat-
ic or manual mode, thereby triggering undesired
gear changes.Keylock positionThe ignition key can be withdrawn only in selec-
tor lever position P.
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withdrawn.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.Release button
The release button (arrow) in the selector lever
prevents unintentional gear changes.
The release button must be pressed when shifting
to position R or P.
StartingThe engine can be started only if the brake pedal
is depressed and the selector lever is in position
P or N.Moving offfOnly select the desired position for moving off
(D, M or R) when the engine is idling and the
brake pedal is depressed.
fSince the vehicle creeps when in gear, do not
release 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 Positions P – Parking lock fSelect only when car has been stopped.
fEngage parking lock after applying the hand-
brake and release it before releasing the hand-
brake.
The ignition key can be withdrawn only in
selector lever position P. R – Reverse fSelect only when car has been stopped and
the brake is applied. N – Neutral Selector lever position N must be selected for to-
wing or in car washes, for example.
fSelect the desired position for moving off (D,
M or R) only when the engine is idling and while
depressing the brake pedal.
fSelect position N while driving only if the car
is threatening to skid in slippery conditions.
Otherwise N should not be selected when dri-
ving.
D – Automatic selection mode fSelect position D for “normal” driving. The ge-
ars 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.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator pe-
dal.
Depending on lateral acceleration, upward shifts
on bends are not made until the engine-speed limit
is reached.
Under braking, and depending on the amount of
deceleration, the Tiptronic shifts down earlier.
For subsequent cornering, the right gear is enga-
ged when pressure is applied to the brakes before
the bend.
The bend is taken in the right gear, and when you
accelerate out of the bend you do not have to shift
down. Driving off
In 2nd gear, the vehicle drives off with the throttle
only slightly open.
Drive off in 1st gear with the throttle open wider
or when the engine is cold.

Shifting Gear
Slip monitoring When the speeds of rotation of the front and rear
axles differ by more than the maximum permissib-
le value, integrated slip monitoring shifts up to the
next gear.
This increases driving stability on a slippery sur-
face.
Note
fSlip monitoring is also deactivated when
Porsche Stability Management (PSM) is swit-
ched off. Stopping fFor 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.
fFor a longer stop with the engine running,
select position N (neutral).
fDo not hold the car on a slope using the
accelerator. Use the brake pedal or the hand-
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.
Parking fGo easy on the accelerator.
fWhen parking or maneuvring in a small space,
control the speed by careful use of the footbra-
ke. Driving in winter In wintery road conditions it is advisable to take
steep inclines in manual mode. This prevents the
occurrence of gear changes that could cause
wheelspin. Tow-starting, towing fPlease observe the chapter “TOWING” on Page
254.
