Fading and drifting
FM range is limited to
about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving aw ay from the desired sta-
tion’s transmitter, the signal will tend to fade and/
or drift. This condition is more prevalent with FM
than AM, and is often ac companied by distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjust-
ing the tone control for greater bass response un-
til the disturbance has passed.
Multipath
Because of the reflecting characteristics of FM,
direct and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception. Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.
Compact disc player
Caution!
To avoid damage to compact disc player and
discs.
f Use only compact discs labeled as shown, hav-
ing no dirt, damage or warpage.
f Never 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.
f Do 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. f
When not in use, take th e disc out of the player,
put the disc back into its case and store it
away from dust, heat, damp and direct
sunlight.
Leaving the disc on the dashboard in the sun
can damage the disc.
f If 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 seri ous or fatal injury.
When using your cellular telephone, you should al-
ways:
f Give full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
f Keep 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 telephone
manufacturer's instructions before operating
the telephone.
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.
The dealer is familiar with the technical require-
ments 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 tele phone 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. 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.
f Consult 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
f Unscrew external antennas before using an au-
tomatic car-wash.

Operation, Safety
AntennafAlways unscrew the external antenna before
using an automatic car-wash.
Hands-free microphoneHands-free microphones installed at the factory
must be adapted to the type of telephone in use.
Your authorized Porsche dealer will be pleased to
advise you.
iPod, USB and AUXThe interfaces for iPod, USB and AUX are located
in the storage tray between the seats.
fPlease refer to the chapter “External Audio
Source” in the separate PCM/CDR operating
instructions.
Note
Do not leave an iPod, USB storage device or an
external audio source in the vehicle for a
prolonged period as extreme ambient conditions
(temperature fluctuations, air humidity) can occur
in the vehicle.

105
Roof Transport SystemfPlease follow the separate instructions for fit-
ting the Roof Transport System.
f Only use Roof Transport Systems from the
Porsche Tequipment product range or Roof
Transport Systems which have been tested
and approved for your car by Porsche. Fitting
normal commercially available luggage racks
is not possible.
The Porsche Roof Transport System allows you
to carry various sports and hobby equipment.
Your Porsche partner will be pleased to tell you
about the various different uses of the Roof Trans-
port System.
Caution!

Only open the rear lid if this cannot touch the
load.
f Completely remove the Roof Transport System
b e f o re u s i n g a n a u t o m a t i c c a r w a s h - r i s k o f d a -
mage to the vehicle!
f Do not exceed the maximum permitted pay-
load of 132 lbs. (60 kg), the maximum permit-
ted gross weight and the maximum permitted
axle loads.
f Please see the chapter “WEIGHTS” on
Page 272. f
Distribute load evenly, storing heavy items as
low as possible. Items of luggage must not
project beyond the side of the load area.
f Fix and secure every item to the basic carrier
with a rope or lashing strap (do not use elastic
rubber tensioners).
f Before every trip, and at regular intervals
during long trips, check that Roof Transport
System and load are secu re. Re-tighten if ne-
cessary and secure additionally by locking.
f When the Roof Transport System is loaded, the
maximum speed depends on the nature, size
and weight of the load being carried. But never
drive faster than 90 mph (140 km/h).
f With the basic carrier fitted and no load, do not
exceed a maximum speed of 110 mph
(180 km/h).
f Driving, braking and steering behavior change
due to the higher center of gravity and the gre-
ater wind-resistant area. You should adapt your
driving style appropriately.
f Since fuel consumption and noise are incre-
ased with the Roof Transport System fitted, it
should not remain on the vehicle if not in use.
