General recommendations on the use

of driving and manoeuvring aids.

– All vehicles are moving in the same direction

and in adjacent lanes.

– The speed of your vehicle must be between

7 and 87 mph (12 and 140 km/h) (versions

Driving

– When overtaken by a vehicle, the speed

etc.

Have it checked by a CITROËN dealer or a

qualiﬁed workshop.

The system may be temporarily disturbed

by certain weather conditions (e.g. rain,

hail).

In particular, driving on a wet road or going

from a dry to a wet area can cause false

alerts (e.g. presence of a cloud of water

droplets in the blind spot interpreted as a

vehicle).

In bad or wintry weather, ensure that the

sensors are not covered by mud, ice or snow.

Take care not to cover the warning zone in

the door mirrors, or the detection zones on

the front and rear bumpers with adhesive

labels or other objects; they may hamper

correct operation of the system.

Operating limits

No alert is triggered in the following conditions:

– presence of stationary objects (e.g. parked

vehicles, safety rails, lampposts, signs).

– vehicles travelling in the opposite direction.

– on winding roads or in case of sharp turns.

– when overtaking or being overtaken by a

very long vehicle (e.g. truck, bus), which is both

detected in a blind spot from behind and present

in the driver's ﬁeld of vision from the front.

– quick overtaking manoeuvre.

Active Safety Brake with

Collision Risk Alert and

Intelligent emergency

braking assistance

– very heavy traﬃc: vehicles detected in front

and behind are confused with a lorry or a

stationary object.

For more information, refer to the

General recommendations on the use

of driving and manoeuvring aids.

– activation of the Park Assist function.

Malfunction

If the event of a malfunction, this warning

lamp lights up on the instrument panel,

accompanied by the display of a message.

touch screen menu.

This system:

– warns the driver that their vehicle is at risk of

depending on version, a cyclist.

– reduces the vehicle's speed to avoid a

collision or limit its severity.

With MyCitroën Drive

The settings are changed via the Vehicle

touch screen menu.

With MyCitroën Drive Plus

The settings are changed via the ADAS

Deactivation of the system is signalled by

the illumination of this warning lamp,

accompanied by the display of a message.

The speed will be reduced by a

maximum of 12 mph (20 km/h) (versions

with camera only) or by a maximum of 31

mph (50 km/h) (versions with camera and

radar).

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 driver vigilance.

Operating conditions and

limits

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.

The system also takes motorcyclists into

account.

Vehicle moving forward without trailer.

Brake system operational.

This system is comprised of three functions:

– Collision Risk Alert.

– Intelligent emergency braking assistance

(iEBA).

– Active Safety Brake (automatic emergency

braking).

Seat belts fastened for all passengers.

Stabilised speed on roads with no or low

curvature.

This warning lamp lights up on the

instrument panel without any additional

message, to indicate that the automatic braking

system is not available.

As soon as the system detects a

potential collision, it prepares the braking

circuit. This may cause a slight noise and a

slight sensation of deceleration.

This is a normal behavior indicating that a

condition is not fulﬁlled and which does not

request the support of a workshop.

In any situations with ignition on where automatic

braking presents a risk, deactivating the system

is recommended, for instance:

Deactivation/Activation

By default, the system is automatically activated

at every engine start.
