This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed
and operated with minimum distance of 8 in.
(20 cm) between the radiator and your body.
This transmitter must not be co-located or
operating in conjunction with any other antenna or
transmitter.
Radar sensor vision can be impaired by rain,
snow, ice or heavy spray. Vehicles in front will not
be detected properly or may not be detected at
all.
f
Do not use adaptive cruise control under these
conditions.
Warning message
Adaptive cruise control can be deactivated
automatically if the radar sensor is very dirty or is
covered in ice or by an obstacle, in unfavorable
weather conditions (heavy rain) or when driving
through tunnels.
The message “
ACC/PAS unavailable
Service
required
” will appear on the multi-function display
in the instrument panel.

Information
This device complies with Part 15 of the FCC
Rules and with RSS-210 of Industry Canada.
Operation is subject to the following two condi-
tions:
1.
This device may not cause harmful interfe-
rence, and
2.
this device must accept any interference
received, including interference that may
cause undesired operation.
Changes or modifications made to this equipment
not expressly approved by Porsche may void the
FCC authorization to operate this equipment.
This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment
is operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may
cause harmful interference to radio communica-
tions. Operation of this equipment in a residential
area is likely to cause harmful interference in
which case the user will be required to correct the
interference at his own expense.
– This Class A digital apparatus complies with
Canadian ICES-003.
Cet appareil numérique de la classe A est
conforme à la norme NMB-003 du Canada.
Operating principle of adaptive cruise
control (ACC)
No vehicle detected in front – open road
driving
Adaptive cruise control operates like a cruise
control system. The desired speed that was set is
maintained constantly.
Vehicle detected in front – driving in traffic
If a vehicle travelling ahead of you in the same lane
is detected as driving slower than the selected
desired speed, adaptive cruise control will
automatically maintain a set distance from the
vehicle in front.
If 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.
Adaptive cruise control actively keeps your vehicle
at a standstill.
If the vehicle in front drives off, automatic speed
control and distance control can be resumed.
