DS 3: Driving / Active Safety Brake with Collision Risk Alert and Intelligent emergency
braking assistance
DS 3 2016-2025 Owners Manual
For more information,
refer to the General
recommendations on the use of driving
and manoeuvring aids.

This system:
- warns the driver that their vehicle is at risk of
collision with the vehicle in front, a pedestrian or,
depending on version, a cyclist.
- reduces the vehicle's speed to avoid a collision
or limit its severity.
The system also takes
motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road are
not necessarily detected.
This system is comprised of three functions:
- Collision Risk Alert.
- Intelligent emergency braking assistance
(iEBA).
- Active Safety Brake (automatic emergency
braking).

The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not
replace the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system
detects a potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This may
cause a slight noise and a slight sensation of
deceleration.

presence of stationary objects (e.g. parked
vehicles, safety rails, lampposts, signs)...
