DS 3: Active Safety Brake with Collision Risk Alert and Intelligent emergency
braking assistance / Intelligent emergency braking assistance (iEBA). Active Safety Brake
DS 3 2016-2025 Owners Manual
Intelligent emergency braking assistance (iEBA)
If the driver brakes, but not sufficiently to avoid
a collision, this system will provide additional
braking, within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does not
operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates subject to the following
conditions:
- The vehicle's speed does not exceed 37 mph (60
km/h) when a pedestrian is detected.
- The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle or a cyclist
is detected.
- The vehicle's speed is between 6 mph and
53 mph (10 km/h and 85 km/h) (versions with
camera only) or 87 mph (140 km/h) (versions
with camera and radar) when a moving vehicle is
detected.
This warning lamp flashes (for
approximately 10 seconds) as soon as the
function applies the vehicle’s brakes.
With an automatic gearbox or drive selector,
in the event of automatic emergency braking
bringing the vehicle to a complete stop, keep the
brake pedal depressed to prevent the vehicle from
moving off again.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can maintain
control of the
vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may
vibrate slightly while
the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.

In the event of a malfunction,
