Lane Change Assist (LCA)
152
General information
– The system provides support when driving at
speeds above approx. 10 mph (15 km/h).
– At speeds below 10 mph (15 km/h), the driver is
supported by Rear Turn Assist, however, only
when driving off and on the vehicle side on which
the turn signal was actuated.
– Rear Turn Assist is active at speeds up to approx.
12 mph (20 km/h).
– Lane Change Assist and rear turn assist are not
available if the system detects that the radar
sensors are covered.
– The radar sensors can sometimes detect other
objects (e.g. high or raised crash barriers), not
only vehicles.
– The display is designed so that you notice it
merely by glancing at the door mirror.
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.

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.

Operating principle
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 (approach
zone) and the blind spot.
Whenever Lane Change Assist regards the speed
difference and distance as critical for changing
lanes, this is indicated on the relevant door mirror.
The two sides of the vehicle are shown separately
here. The warning indicator on the left door mirror
assists the driver when changing to the left lane, for
example.
If a vehicle regarded as critical has switched on its
turn signal, the respective warning indicator on the
door mirror will flash brightly and briefly several
times.
If you overtake another vehicle slowly (with a speed
difference of less than approx. 10 mph (15 km/h)),
the warning indicator lights up as soon as that ve-
hicle is in your blind spot and is detected by Lane
Change Assist. If the speed difference is greater, no
warning indicator will be activated on the door
mirror.
The speed range of the Lane Change Assist is not
reached immediately after driving off. Until it is
reached, the driver is supported by the Rear Turn
Assist.
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.
Information
The radar sensors cover the adjacent lane to the left
and right. Other lanes are not covered by the radar
sensors.
Information and warning stage
Lane Change Assist has two indicator levels that are
activated as appropriate, depending on whether or
not the turn signal has been set.
