Driving and Driving Safety
Acute warning (acoustic, visual and tangible)
If the driver does not react to the prewarning by
braking, this is quickly followed by an acute
warning, which involves a braking jolt as well as
the acoustic and visual warning.
A braking jolt is felt in the vehicle as a result of a
very quick build-up of brake pressure. This alerts
the driver to the traffic situation.
The driver can still prevent a collision by reacting
accordingly in this dangerous situation.
Risk of collision with the vehicle in front.
f
Brake immediately.
Information
The situations described below lead to the
assumption that the driver is driving carefully and
the prewarning and acute warning functions are
disabled:
– The driver drives around tight corners.
– The driver is braking.
– If the driver accelerates sharply, this action is
interpreted as an active driving request (e.g.
indicating the driver’s intention to overtake).
Switching Porsche “Active Safe” warnings
on/off
The latent warning and prewarning functions are
switched off by default. The acute warning
function is active.
Latent warnings and prewarnings can be activated
under “ Prewarning on ” on the multi-function
display.
The settings remain stored when the ignition is
switched on and off.

PLEASE SEE THE CHAPTER “ACTIVE SAFETY –
PORSCHE “ACTIVE SAFE”” on page 167.
Car Audio Operation/Tips
For radio operation see your radio manual
which is included with your on-board
literature.
FM reception
A vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good
reception.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely
normal for a given reception area, and they do not
indicate any problem with the radio itself.
Information
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and
approved by Porsche may impair radio reception.
Fading and drifting
FM range is limited to about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving away from the desired
station's transmitter, the signal will tend to fade
and/or drift. This condition is more prevalent with
FM than AM, and is often accompanied by
distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or
selection of a stronger signal.
Insufficient distance
