Driving

It is set via the Driving / Vehicle touch

screen menu.

Deactivation of the system is signalled by

the illumination of this warning lamp,

Active Safety Brake with

Collision Risk Alert and

Intelligent emergency

braking assistance

accompanied by the display of a message.

Operating conditions and limits

ESC system in working order.

Refer to the General recommendations on the use

of driving and manoeuvring aids.

ASR system activated.

Seat belts fastened for all passengers.

Stabilised speed on unwinding roads.

In the following cases, deactivating the system

via the vehicle's configuration menu is advised:

– Towing a trailer.

– Carrying long objects on roof bars.

– Vehicles with snow chains fitted.

– Before using an automatic car wash, with the

engine running.

The vehicle has a multifunctional camera located

at the top of the windscreen and, depending on

version, a radar located in the front bumper.

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.

This system does not avoid 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 the state of the traffic, observing the

driving regulations.

– Before placing the vehicle on a rolling road in a

workshop.

– Towed vehicle, engine running.

– Following impact to the windscreen close to the

detection camera.

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.

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.

This system is comprised of three functions:

– Collision Risk Alert.

– Intelligent emergency braking assistance.

– Active Safety Brake (automatic emergency

braking).

The system is automatically deactivated

once the use of a different diameter

"space-saver" type spare wheel is detected, or

if a fault with the two lateral brake lamps is

detected.

Deactivation / Activation

By default, the system is automatically activated

at every engine start.

Driving

It is possible that warnings are not given,

are given too late or seem unjustified.

The driver must always stay in control of the

vehicle and be prepared to react at any time to

avoid an accident.

threshold chosen by the driver, several different

levels of alert may be triggered and displayed in

the instrument panel.

The system takes account of the vehicle

dynamics, the speed of your vehicle and the one

in front, the environmental conditions and the

operation of the vehicle (actions on the pedals,

the steering wheel, etc.) to trigger the alert at the

best moment.

Level 1 (orange): visual alert only,

indicating that the vehicle in front is very

close.

The message "Vehicle close" is displayed.

Level 2 (red): visual and audible alert,

indicating that a collision is imminent.

The message "Brake!" is displayed.

Level 3: in some cases, a vibration alert in the

form of micro-braking can be given, confirming

the risk of collision.

Intelligent emergency braking

assistance

If the driver brakes, but not sufficiently to avoid a

collision, this system will supplement the braking,

within the limits of the laws of physics.

This assistance will only be provided if the driver

presses the brake pedal.

After an impact, the function

automatically stops operating. Contact a

dealer or a qualified workshop to have the

system checked.

Active Safety Brake

Collision Risk Alert

This function warns the driver that their vehicle is

at risk of a collision with the vehicle in front, or a

pedestrian or cyclist present in their traffic lane.

Modifying the alert trigger threshold

This trigger threshold determines the sensitivity

with which the function warns of the risk of

collision.

The threshold is set via the Driving /

Vehicle touch screen menu.

►ꢀ Select one of the three pre-defined thresholds:

– "Distant".

– “Normal".

– “Close".

The last threshold selected is memorised when

the ignition is switched off.

Where the speed of your vehicle is too

high approaching another vehicle, the

first level of alert may not be displayed: the

level 2 alert may be displayed directly.

Important: the level 1 alert is not displayed

when there is a stationary obstacle or when

the "Close" trigger threshold has been

selected.

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

Depending on the degree of risk of collision

detected by the system and the alert trigger

Driving

Operation

The system operates subject to the following

conditions:

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.

(e.g. pedestrian, vehicle, tree, barrier) present in

their field of detection.

Rear parking sensors

– 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 immediately flashes

(for approximately 10 seconds) when the

function acts on the vehicle’s braking.

With an automatic gearbox or drive selector, in

the event of automatic emergency braking until

the vehicle comes to a complete stop, keep the

brake pedal pressed down to prevent the vehicle

from moving off again.

The system is switched on by engaging reverse

gear, as confirmed by an audible signal.

The system is switched off when you come out of

reverse gear.

Malfunction

In the event of a fault with the system, you

are alerted by the fixed illumination of this

warning lamp, accompanied by the display of a

message and an audible signal.

Audible assistance

Contact a dealer or a qualified workshop to have

the system checked.

If these warning lamps come on

after the engine has been switched

off and then restarted, contact a dealer or a

qualified workshop to have the system checked.

The system signals the presence of obstacles

within the sensors’ detection zone.

Parking sensors

Refer to the General recommendations on the use

of driving and manoeuvring aids.

With a manual gearbox, in the event of automatic

emergency braking until the vehicle comes 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.

Depending on version, in the example shown, only

the obstacles present in the shaded area will be

signalled by the audible assistance.

The proximity information is given by an

intermittent audible signal, the frequency of

Using sensors located in the bumper, this

system signals the proximity of obstacles
