– when approaching humps and dips
– in urban traffic
– on winding and narrow country roads
– in unclear traffic situations such as intersections
or tollbooths
– off-road or on unpaved or slippery roads
The system does not always keep the vehicle in the
center of the lane or in a central position behind the
last vehicle in the line.
Active Lane Keeping does not react to people and
animals or vehicles crossing lanes or oncoming ve-
hicles in the same lane. These are not detected as
obstructions by the sensors.
e Never use Active Lane Keeping in the specified
situations.
e Do not use Active Lane Keeping to steer the ve-
hicle around obstructions lying on the road.
Information
If there is a fault in the system or if Active Line
Keeping does not function as described in this sec-
tion, do not use the assistance function. Visit an au-
thorized Porsche dealer. Porsche recommends an
authorized Porsche dealer, as they have trained
technicians and the necessary parts and tools.
Responding to warning symbols
Always heed any warning and information messages
displayed in the vehicle.
> Please see chapter "Warning and information
messages" on page 244.

Operating principle
Active Lane Keeping uses the front camera as well as
front and rear radar to continuously scan the area
around the vehicle and helps the driver to keep the
vehicle in the selected lane.
– When the system is active, the driver can set a
preferred position within the lane. When the
driver keeps the vehicle at the desired position
for several seconds, the system ends lane center
guidance and starts driving at the selected offset
position. The shift in position is reset again when
the system becomes passive or is switched off
(e.g. by activating the turn signal changing lanes
or braking).
– The system always prioritizes the lane markings
over other objects (e.g. vehicles). In some cases,
this can mean that the driver has to position the
vehicle in the center of the lane in order to acti-
vate the system. Activation of the system out-
side the center of the lane is prevented so that
the driver does not feel a strong movement on
the steering wheel immediately after the system
is activated.
– The driver is responsible for moving to the side of
the road to create a lane for emergency vehicles.
In such situations, the driver can switch off the
system or override the system using the steering
wheel.
Behavior when the turn signal is activated
Activating the turn signal alerts the system to the
driver's intention to change lanes. Active Lane
Keeping therefore does not intervene in steering in
this case.
Lane Change Assist, on the other hand, assists the
driver when changing lanes by also activating the
turn signal.
Active Lane Keeping
> Please see chapter "Lane Change Assist (LCA)"
on page 142.
Behavior if there is no steering activity
The driver's steering behavior is monitored when
Active Lane Keeping is switched on and active. If
there is no steering activity (e.g. hands not on the
steering wheel or only resting lightly), a warning ap-
pears on the instrument cluster. The system
prompts the driver to actively take over the steering.
If the driver does not react to the takeover prompt,
the system switches to a passive state. For vehicles
with activated emergency stop function:
hicle can be slowed to a standstill.
