Driving and Driving Safety
Possible distance settings
Automatic braking to a stopIf the vehicle in front stops, adaptive cruise control
will slow your vehicle down
to a stop provided this
is possible within the control limits of the system.
The display lights up on the instrument panel.
The vehicle is actively held at a stop.
For information on the HOLD function:
f Please see the chapter “HOLD FUNCTION:
DRIVE-OFF ASSISTANT AND STANDSTILL
MANAGEMENT” on page 206.
Note
Depending on the traffic flow, e.g. slow moving
traffic, stopping is initiated by a slow crawling
phase which ends in vehicle standstill.
Caution!
Brake pedal feels different. When adaptive
cruise control is operating normally or when
the HOLD function is active, the brake pedal
may feel different and you may hear
hydraulic noises.
This behavior is no rmal for the system.
It is not a fault.
Driving off againThe vehicle can be driven off again after being
stopped and speed and distance control will be
resumed, depending on the operating state of the
adaptive cruise control system.

Driving and Driving Safety
Exceptions for adaptive cruise control
Adaptive cruise control is
not available in the
following situations:
– If the ignition is switched off.
– When PSM is off.
– If the driver’s door is opened and the driver’s seat belt is not fastened.
– When parking or maneuvering in very tight spaces.
– If the PDK selector lever is at position N, R or
P .
– On upward or downward slopes of more than 20 %.
– When the electric parking brake is activated.
If one of these exception situations occurs when
adaptive cruise control is switched on, adaptive
cruise control will be switched off.
A message to this effect will appear on the
multi-function display. Messages on the multi-function display
If adaptive cruise control was deactivated
automatically or if an action cannot be performed,
a message to this effect in blue appears on the
multi-function display.
–“
ACC not available! ”
Adaptive cruise control is not available,
e.g. when maneuvering.
–“ ABS/PSM intervention!”
Adaptive cruise control was deactivated
because ABS or PSM intervened as a control
mechanism.
–“ Electric parking brake! ”
Adaptive cruise control was deactivated
because the electric parking brake was
activated.
–“ Selector position!”
Adaptive cruise control was deactivated
because the PDK select or lever is not in
position D or manual position M.
–“ Impossible while parked ”
The required action is not possible because
your vehicle is stationary, e.g. when setting
a desired speed.
–“ Speed! ”
Adaptive cruise control was deactivated
because the rpm limit of the engine was
reached in manual position M of the PDK
selector lever. –“
Gradient too steep! ”
The desired distance or the desired speed
cannot be set because the gradient on the
road is too steep.
–“ Stationary object ”
The action is not possi ble because a stationary
object was detected ahead.

Traffic situations in which vehicles are
not reliably detectedThe radar sensor for adaptive cruise control
scans a narrow, cone-shaped area in front of
your vehicle.
Detection can be limited or unreliable, depending
on the traffic situation and the size of the vehicle
in front. The system may brake too late or
unexpectedly. Stationary vehicles are not
detected. The system is unable to react to them.
Tip on driving
fDrive with extreme care.
f Slow down if necessary.
A – Vehicles changing lanes/cutting in
If a vehicle is changing la nes or cutting in ahead of
you in the same lane, th e vehicle will only be
detected when it has moved completely into your
lane.
B – Vehicles with a small cross-section/
narrow vehicles
Narrow or small vehicles will not be detected or
will be detected too late.
C – Driving into and out of corners
When driving into and out of corners, vehicles will
not be detected or will be detected too early, or
adaptive cruise control will react to vehicles in
adjacent lanes.

188
Driving and Driving Safety
D – Vehicles with large overhangs
The tail of the vehicle will not be detected
correctly on vehicles with large overhangs,
e.g. lumber trucks.
Warning!
Risk of accidents. Danger of collision with the
vehicle in front.
f Drive with extreme care.
fSlow down if necessary.
E – Stationary vehicles
A stationary vehicle that appears suddenly in the
detection field of the radar sensor, e.g. after a
vehicle in front changes lanes, will not be detected
by the ACC.
Warning!
Risk of accidents. Danger of collision with the
stationary vehicle.
f Drive with extreme care.
fSlow down if necessary.

Car Audio Operation/TipsFor radio operation see your radio manual
which is included with your on-board
literature.FM receptionA 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.
Note
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.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or
mountains, the radio sound may be accompanied
with static or fluttering because of the
characteristic of FM.
In a similar effect, a flutt ering noise is sometimes
heard when driving along a tree-lined road.
This static and flutteri ng can be reduced by
adjusting the tone control for greater bass
response until 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
multipath 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,
having 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
fingerprints, 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 the 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
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:
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
telephone.
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.
They are 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 tele phone 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.
