Caution!
To avoid damage to compact disc player and
discs.
fUse only compact discs labeled as shown, hav-
ing no dirt, damage or warpage.
fNever attempt to disassemble or oil any part
of the player unit. Do not insert any object oth-
er 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.
This may cause poor sound quality.
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 re-
garding 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 personal injury or
death.
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; andfKeep 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.
It is essential to observe the instructions of
the telephone manufacturer before putting
the telephone into operation.
Any portable telephone or radio transmitter which
is used in a Porsche must be properly installed in
accordance with the technical requirements of
Porsche.
The transmission power must not exceed
10 W.
The devices must possess a type approval for
your vehicle and have an “e“ symbol.
If you should require equipment with transmission
power values greater than 10 W, please consult
your authorized Porsche dealer for this purpose.
He is familiar with the technical requirements for
installing devices of this kind.
The antennas for all radios and telephones with a
transmitting antenna must be externally mounted.
The improper installation of radios or telephones
or use of a radio or telephone with a transmitting
antenna inside the car may cause the warning
lights to come on.
Improper installation of such equipment can cre-
ate a discharged battery or excessive current
draw from added equipment.

Controls, Safety, Instruments If aftermarket systems are installed by non-dealer-
ship technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
fConsult your authorized Porsche dealer about
the installation of non Porsche approved equip-
ment.
Reception quality
The reception quality of your car telephone will
change constantly when you are driving. Interfer-
ence caused by buildings, landscape and weather
is unavoidable. It may become particularly difficult
to hear when using the hands-free function due to
external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an au-
tomatic car-wash.
Porsche Communication
Management (PCM)
Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
fOperate the components while driving only if
the traffic situation allows you to do so safely.
fCarry out any complicated operating or setting
procedures only with the vehicle stationary
fIf it is necessary to operate these components
while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer to the separate operating instructions
before putting the PCM into operation.
When put into operation for the first time, a dis-
tance of approx. 3 miles (5 km) must be driven in
order for the navigation system to complete the
process of fine calibration. The same applies
when the tires are changed (e.g. summer/winter
tires) or new tires fitted. Full location accuracy is
not yet achieved during the fine-calibration pro-
cess.If the vehicle has been transported (e.g. ferry, car
train), the system may take a few minutes after be-
ing switched on before it determines the current
location.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational once more.
Satellite radioYou must have the satellite radio activated before
you can put it into operation. You will need a con-
tract with a provider in order to use this radio.
fRefer to the separate radio operating instruc-
tions before putting into operation.

Roof Transport SystemfPlease follow the separate instructions for
fitting the Roof Transport System.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 195.
Fitting normal commercially available luggage
racks is not possible.
ThePorsche Roof Transport System allows the
transport of various sports and hobby equipment.
Your authorized Porsche dealer will be pleased to
tell you about the manifold uses of the Roof Trans-
port System.
Warning!
Risk of an accident, loss of control and dam-
age to the vehicle.
fCompletely remove the Roof Transport System
before using an automatic car wash – risk of
damage to the vehicle.
fDo not exceed the permissible roof load, the
permissible gross weight and the permissible
axle loads.
Please observe the chapter “WEIGHTS” on
Page 363.
fDistribute load evenly, with heavy items as low
as possible. Items of luggage must not project
beyond the side of the load area.
fFix and secure every item to the basic carrier
with a rope or lashing strap (do not use elastic
rubber tensioners).
fBefore every journey, and at regular intervals
during long trips, check that Roof Transport
System and load are secure. Re-tighten if
necessary and secure additionally by locking.When the Roof Transport System is loaded, the
maximum speed depends on the nature, size and
weight of the load being carried.
fBut never drive faster than 90 mph
(140 km/h).
fWith the basic carrier fitted and no load, do not
exceed a maximum speed of 110 mph
(180 km/h).
Adapt your driving style and speed to the changed
conditions.
Nevertheless, Porsche recommends that you do
not exceed the posted speed limit.
Driving, braking and steering behavior change due
to the higher center of gravity and the greater
wind-resistant area. You should adapt your driving
style appropriately.
fSince fuel consumption and noise are in-
creased with the Roof Transport System fitted,
it should not remain on the car if not in use.

Shifting Gear, Traction Systems
203
Tiptronic SThe Porsche Tiptronic is a six-speed transmission
and features an “automatic” and a “manual” gear-
shift mode.
Inautomatic selection mode (selector lever po-
sitionD), 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.
Inmanual selection mode (selector lever
positionM), you change gear using the rocker
switches on the steering wheel or by pushing the
selector lever forward or back.
You can change between selector lever positions
Dand M as you wish while driving.
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 pressedRelease button
The release button (arrow) on the front side of the
selector lever prevents unintentional gear chang-
es.
The release button must be pressed when shifting
to position Ror P.
The selector lever cannot be operated in the event
of an electrical fault.
fPlease observe the chapter “SELECTOR LE-
VER EMERGENCY RELEASE” on Page 210.
StartingThe engine can be started only in selector lever
positionPor 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.

D - Automatic selection mode (in the road
driving program)The functions of selector lever positions Dand M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
fUse selector lever position D for “normal” driv-
ing.
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 bends, are
prevented by swiftly releasing the accelerator ped-
al.
Depending on lateral acceleration, upward chang-
es on bends 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 en-
gaged when pressure is applied to the brakes be-
fore the bend.The bend is taken in the right gear, and when you
accelerate out of the bend you do not have to
change down.
Moving off
In 2nd gear, the vehicle moves off with the throttle
only slightly open. Move off in 1st gear with the
throttle open wider or when the engine is cold.
When PSM is switched off, the car generally
moves off in 1st gear.
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 bends and on entering
built-up areas.
– Shifting down on downward slopes (engine
braking).
– Shifting down 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 accel-
eration) and overrunning,
– When the vehicle is stationary (e.g. at a junc-
tion).The system leaves manual selection mode:
– automatically after around 8 seconds
(unless car is cornering, overrunning 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 sport-
iest gear-changing map, i.e. to the highest pos-
sible 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%).

Shifting Gear, Traction Systems Kickdown
The kickdown function is active in selector lever
position D.
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
full-throttle position.
D - Automatic selection mode (in the off-
road driving program)The functions of selector lever positions Dand M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
fUse selector lever position D for “normal” driv-
ing.
The gears are shifted automatically according
to the accelerator position and speed.
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 difficult terrain.Depending on the route profile, the gear-changing
points are shifted towards higher or lower engine-
speed ranges. On steep downhill stretches, up-
ward shifts are prevented until medium engine
speeds are reached (at least 2,500 rpm).
When the car is overrunning, an automatic upshift
does not occur when the engine speed limit is
reached.
Moving off
The car moves off in 1st gear.
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).
– Shifting down for brief spurts of acceleration.
– Selecting 1st/2nd or 3rd gear for moving off.
The manual selection mode remains engaged:
– For overrunning
– Depending on lateral acceleration
– When the vehicle is stationary (e.g. at a junc-
tion).The system leaves manual selection mode:
– Automatically after around 8 seconds
(unless car is subject to high lateral accelera-
tion, is overrunning 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 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
full-throttle position.
Tip on driving
Unlike in the on-road driving program, an automat-
ic upshift is not performed in manual selection
modeM when the engine-speed limit is reached.

Shifting Gear, Traction Systems
Porsche Traction Management (PTM)Porsche Traction Management is a full-time all-
wheel control system designed to influence the
longitudinal and lateral dynamics. It is closely
linked with the Porsche Stability Management
(PSM) system:
PTM ensures the best possible power distribution
to the four driven wheels at the front and rear ax-
les. The system realises this optimal traction by in-
tervening in the lock control function of the trans-
fer case and rear differential. PTM is active at all
times and, unlike the PSM, cannot be switched off.Advantages of PTM
– Obvious improvement in traction, driving stabil-
ity and steering ability of the car.
– Vehicle is more manageable when driven at its
performance limits.
– Improved straight-ahead tracking and stability.
– The aforementioned features allow for a sport-
ier setup of the running gear.
– The TCS and ABD provide even better traction
for all wheels.
Safety notes!
In spite of the advantages of PTM, it is still the driv-
er’s responsibility to adapt his driving style and
maneuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PTM.
Risks of accident due to inappropriate speed
cannot be reduced by PTM.
