System limitations
– Only Rear Turn Assist is available at speeds be-
low 9 mph (15 km/h). When driving off, the
driver is therefore only supported by monitoring
of the area behind the vehicle on the side of the
vehicle on which the direction indicator was
actuated.
– Lane Change Assist and Rear Turn Assist are not
available if the system detects that the radar
sensors are covered.
– The rear collision warning may be switched off if
there is a malfunction in the Lane Change Assist.
– The radar sensors cover the adjacent lane to the
left and right. Other lanes are not covered by the
radar sensors.
– The radar sensors can sometimes detect other
objects (e.g. high or raised crash barriers), not
only vehicles.
Information
If the position of the radar sensors was changed fol-
lowing an accident, for example, this can impair the
function of Lane Change Assist.
e Visit an authorized Porsche dealer. Porsche rec-
ommends an authorized Porsche dealer, as they
have trained technicians and the necessary parts
and tools.
Information
To ensure that Lane Change Assist operates
correctly:
e Do not cover the radar sensors on the rear
bumper (e.g. with stickers). Keep the area clean
and free of snow and ice.
e Do not cover the warning indicator in the exterior
mirror (e.g. with stickers).
e Subsequent painting of the bumper may lead to a
reduction in the sensor range owing to the
thicker coating layer. The electrical properties
may also differ from those of the approved
paints.

Lane Change Assist (LCA)
Operating principle
Lane Change Assist (LCA) warns the driver about
vehicles that are approaching from the rear or are
located in the blind spot. This applies both when
overtaking other vehicles and when your vehicle is
being overtaken.
Using the radar sensors integrated in the rear
bumper, Lane Change Assist measures the distance
and speed difference of the detected vehicles in re-
lation to your vehicle. The radar sensors cover an
area of up to 230 ft. (70 m) to the rear and the blind
spot area.
As soon as the direction indicator is activated for a
lane change regarded as critical, the warning indica-
tor in the respective exterior mirror lights up brightly
and briefly several times. The system therefore pro-
vides assistance separately for both sides of the
vehicle.
When slowly overtaking another vehicle (speed dif-
ference of less than approx. 9 mph (15 km/h)), the
warning indicator lights up as soon as this vehicle is
in your blind spot area and is detected by Lane
Change Assist. If the speed difference is greater, no
warning indicator will be activated on the door
mirror.
The rear turn assist is always automatically activated
together with the Lane Change Assist. The driver is
supported by Rear Turn Assist until the Lane Change
Assist speed range is reached after driving off.
When the turn signal is on, the Rear Turn Assist de-
tects objects located next to and behind your ve-
hicle, but only at the side on which the turn signal
has been activated. If a potential hazard is detected,
the respective warning indicator on the door mirror
lights up. If your own calculated driving path crosses
that of a detected vehicle on the side of the vehicle
on which the turn signal has been activated, the re-
spective warning indicator on the door mirror will
flash brightly and briefly several times.
