DS 3: Active Lane Departure Warning System / Driving situations and related alerts
DS 3 2016-2023 Owners Manual
The table below describes the alerts and messages displayed in different
driving situations.
The actual order of display of these alerts may be different.


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...
The system goes into standby automatically in
the following cases:
ESC deactivated or operation triggered.
Speed below 43 mph (70 km/h) or greater than
112 mph (180 km/h),
Electrical connection of a trailer...
Other information:
For
the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control is
activated. If you hold one of the speed setting
modification buttons down, a very rapid
change in the speed of your vehicle may occur...
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...
