Alarms
Important legal and safety information
regarding the use of cellular telephones
Some states may prohibit the use of cellular
telephones 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 lead to serious personal injury
or death.
When using your cellular telephone, you should
always:
Give full attention to your driving - pull off the
road and park before making or answering a
call if traffic conditions so require; and
Keep both hands on the steering wheel - use
hands-free operation (if available) - pull off
the road and park before using a hand-held
telephone.
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 create
a discharged battery or excessive current draw
from added equipment.
If aftermarket systems are installed by non-deal-
ership technicians or outside the selling dealer,
problems may result. Installation of aftermarket
equipment is not covered under the New Car War-
ranty.
Consult your authorized Porsche dealer about
the installation of non Porsche approved
equipment.
Reception quality
The reception quality of your car telephone
will change constantly when you are driving.
Interference 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.
