Automatic Speed Control The automatic speed control maintains any
selected speed between 15 mph and 145 mph/
30 km/h and 240 km/h without you having to use
the accelerator.
The automatic speed control is operated with the
lever on the steering wheel.
Warning!
Risk of accident and consequent personal in-
jury. A constant speed may not be safe in
heavy traffic, or on winding or slippery
roads.
With the speed control system engaged, the
engine speed will not return to idle when re-
moving the foot from the accelerator pedal.
fDo not use the speed control when it may be
unsafe to keep the car at a constant speed.
fObserve all local and national speed limits. Switch automatic speed control readiness
on fPress button A on the automatic speed control
lever.
This green indicator light in the
speedometer now indicates readiness.
Hold and store speed fBring the car to the desired speed with the
accelerator.
fThen briefly push the operating lever forward

fIncrease the speed as usual with the
accelerator.
When you ease off the accelerator, the
previously saved value is set again.
Option 2
fPush operating lever forward (position 1) until
the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 3
fPush lever slightly forwards (position 1)
(a maximum of 10 times).
The speed is increased by 1 mph (1.6 km/h)
each time.
Note on operation
Speed control operation is automatically interrupt-
ed if the speed is increased by more than approx.
16 mph (25 km/h ) for longer than 20 seconds.

Decelerating Option 1
fPull operating lever towards the steering wheel
(position 2) until the desired speed is reached.
The speed reached is maintained and stored
when the lever is released.
Option 2
fBriefly move lever towards the steering wheel
(position 2) (a maximum of 10 times).
The speed is reduced by 1 mph (1.6 km/h)
each time.

operation fPull operating lever downwards briefly
(position 3) or
fOperate brake or clutch pedal or
fSwitch Tiptronic transmission to selector lever
position N.
fPlease observe the chapter “TIPTRONIC S” on
Page 165.
The speed driven before the interruption remains
stored in the memory.
Automatic speed 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 to approx.
6 mph (10 km/h) below the set vehicle speed
for longer than 5 seconds (upward slopes).
– For PSM control operations.
Resuming the stored speed fBriefly push operating lever upwards
(position4).
The speed control accelerates/decelerates
the vehicle to the stored speed.
The stored speed should only be recalled when
traffic conditions and the road surface so permit.Switching automatic speed control
readiness off fPress button A on the automatic speed control
lever.
The green readiness light in the speedometer
goes off.
When the vehicle is parked and the ignition
switched off, the memory is cleared.
Important note
On upward or downward slopes, the set speed
cannot always be maintained by the automatic
speed control.
To obtain sufficient engine braking or a better en-
gine-speed range, therefore, you have to select a
lower gear.

Compact disc player
Caution!
To avoid damage to compact disc player and
discs.
fUse only compact discs labeled as shown, ha-
ving no dirt, damage or warpage.
fNever attempt to disassemble or oil any part
of the player unit.
Do not insert any object other than a disc into
the slot.
Remember there are no user-serviceable parts
inside the compact disc player.
fDo not allow the disc to sustain any finger-
prints, scrapes or stickers on the surfaces.

Hold the disc only on the edge or center hole.
fWhen not in use, take the disc out of the player,
put the disc back into its case and store it
away from dust, heat, damp and direct sun-
light.
Leaving the disc on the dashboard in the sun
can damage the disc. fIf the disc gets dirty, clean the disc by wiping
the surfaces from the center to the outside in
a radial direction with a soft cloth.
Do not use a conventional record cleaner or
anti-static record preservative.
Disc cleaners are available in audio stores.
Car Telephone and
Aftermarket Alarms Important legal and safety information
regarding the use of cellular telephones:
Some states may prohibit the use of cellular tele-
phones while driving a vehicle. Check the laws and
regulations on the use of cellular telephones in the
areas where you drive.
Danger!
Risk of an accident.
Severe personal injury or death can result in
the event of an accident.
Looking away from the road or turning your
attention away from your driving can cause
an accident and serious or fatal injury.
When using your cellular telephone, you should al-
ways:
fGive full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
fKeep both hands on the steering wheel - use
hands-free operation (if available) - pull off the
road and park before using a hand-held tele-phone.

Shifting Gear

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.

168
Shifting Gear Shifting gear on the steering wheel
With the toggle switches on the steering wheel,
you can change temporarily from automatic
selection mode D to manual mode M.
Advantages:
– Shifting down before bends and on entering
built-up areas.
– Shifting down on downward slopes (engine
braking).
– Shifting down for brief spurts of acceleration.
– Selecting 1st gear for moving off.
The manual selection mode remains engaged:
– for cornering (depending on the lateral
acceleration) and overrunning,
– when the vehicle is stationary
(e.g. at a junction).
The system leaves manual selection mode:
– automatically after approx. 8 seconds
(unless cornering or overrunning),
– if you depress the accelerator to kickdown,
– after moving off. Temporary change-down
Conditions:
Speed is higher than approx. 33 mph (54 km/h).
fDepress accelerator quickly.
The Tiptronic changes temporarily to the sport-
iest gear-changing map, i.e. to the highest pos-
sible gear-changing points. Correspondingly,
the transmission shifts down immediately by
one or two gears.
Ending the function:
fRelease the accelerator markedly. Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to man-
ual mode M using the toggle switches on the
steering wheel.
fFor optimum acceleration, e.g. when overtak-
ing, 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
wide open throttle position.

Shifting Gear
169
M - Manual Selection Mode The currently selected gear is retained if you
change from D to M.
If you shift 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”.
fTherefore shift down manually when accelerat-ing (e.g. to overtake). Two toggle switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward gears.
Shifting up
fPress upper part (+) of a toggle switch.
Shifting down
fPress lower part (–) of a toggle switch.
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
controller.
You can shift down two gears at once by quickly
pressing the toggle switches twice.
If the engine-speed limit is reached, an auto matic
upward shift is performed or, just before idling
speed is reached, a downward 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 cluster will display selector lever posi-
tion D.
fTo remedy the fault, please consult an author-
ized Porsche dealer.
PSM switched off and/or Sport mode
switched on
fPlease observe the chapter “SWITCHING OFF
PSM” on Page 63.
fPlease observe the chapter “SPORT MODE” on
Page 61.
If the PSM is switched off and/or Sport mode is
switched on, an automatic upshift does not occur
when the engine speed limit is reached.
Cancelling upshift suppression
The restriction can be cancelled for one gear
change by depressing the accelerator to
kickdown. If, for example, the engine speed limit
is reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up by accelerating to kickdown.
fDepress the accelerator pedal beyond the
full-throttle point (kickdown).

Power Steering
Warning!
Risk of accident. When the engine is
stationary (e.g. when on tow) or the hydraulic
system fails, there is no assistance for
steering.
Therefore, substantially more force will have
to be exerted in order to steer.
fExercise great care when on tow.
fHave the fault remedied at your nearest authorized Porsche dealer.
Note
The flow noise heard at full steering lock is system
related and does not indicate a defect in the
steering system.
Checking hydraulic fluidThe reservoir is in the engine compartment.
Regular checking of hydraulic fluid is part of
servicing.
fPlease observe the chapter “WORKING IN THE
ENGINE COMPARTMENT” on Page 172.
