DS 3: Driving / Active Lane Departure Warning System
DS 3 2016-2025 Owners Manual
For more information,
refer to the General
recommendations on the use of driving
and manoeuvring aids.
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on motorways
and main roads.

Operating conditions
- Vehicle speed between 43 and 112 mph (70 and
180 km/h).
- Road marked with a central dividing line.
- Steering wheel held in both hands.
- Direction indicators not activated.
- ESC system activated and operational.
The system helps the
driver only if there is
a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operating limits
The system may issue an alert when the
vehicle is travelling on a long, straight
road with smooth road surface even if the
driver thinks they are holding the steering
wheel correctly...
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g. grass verge), it performs the trajectory
correction necessary to restore the vehicle to its
original lane...
Other information:
Operating limits
The system may suggest an inappropriate
parking space (parking prohibited, work in
progress with damaged road surface, location
alongside a ditch, etc.).
The system may indicate that a space has
been found but will not offer it because of a fixed
obstacle on the opposite side of the manoeuvre,
which would not allow the vehicle to follow a
trajectory required for p..
The driver must ensure
that passengers
use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they will
not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodie..
