Operating limits

Collision Risk Alert and

Active Safety Brake

In the following cases, deactivating the

system via the vehicle's configuration menu is

recommended:

when towing a trailer,

when carrying long objects on roof bars or a

roof rack,

before using an automatic car wash, with

the engine running,

before placing the vehicle on a rolling stand

in a workshop,

The system is activated from 3 mph (5 km/h).

It takes account of:

registered vehicles running in the same

direction or stationary,

This system is a driving aid that includes three

functions.

pedestrians in the traffic lane (bicycles,

motorcycles, animals and objects on the

road are not necessarily detected).

Collision Risk Alert: it warns the driver if their

vehicle is at risk of collision with the vehicle in

front or a pedestrian present in their traffic lane.

Intelligent emergency braking assistance:

it supplements the braking action taken by the

driver if this is inadequate.

Active Safety Brake: it intervenes following

the alert if the driver does not react quickly

enough and does not operate the vehicle's

brakes.

when the vehicle is being towed, with the

engine running,

when a "space-saver" type spare wheel is

fitted (depending on version),

following impact damage to the windscreen

close to the detection camera,

if the brake lamps are not working.

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.

This system does not avoid the need for

vigilance on the part of the driver.

If the driver fails to act, it contributes

towards avoiding a collision or limiting

its severity by reducing the speed of your

vehicle.

It is possible that warnings are not given,

are given too late or seem unjustified.

Consequently, always stay alert and be

prepared to react at any time to avoid an

accident.

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.

Activation and operating

conditions

The vehicle has a camera located at the top of

the windscreen.

Collision Risk Alert

Intelligent emergency

braking assistance

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: alert level 1 is never displayed

when the "Close" trigger threshold has

been selected.

Depending on the degree of risk of collision

detected by the system and the alert threshold

chosen by the driver, different levels of

alert can be triggered and displayed in the

instrument panel.

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 you

press the brake pedal.

Level 1 (orange): visual alert only,

signalling to you that the vehicle in

front is very close.

The message "Vehicle close" is

displayed.

Active Safety Brake

Modifying the alert trigger

threshold

This level of alert is based on the inter-vehicle

time between your vehicle and the vehicle in

front.

This threshold determines how you wish

to be alerted of the presence of a moving

or stationary vehicle in front of you, or a

pedestrian present in your traffic lane.

The current threshold can be modified via the

vehicle configuration menu.

Level 2 (red): visual and audible

alert, warning you that a collision is

imminent.

The message "Brake!" is displayed.

You can select one of three predefined

thresholds:

This level of alert is based on the time before

collision. It takes account of the vehicle

dynamics, the speed of your vehicle and the

one in front, the environmental conditions, the

operation of the vehicle (cornering, pedals

pressed, etc.) to trigger the alert at the best

moment.

"Distant",

"Normal",

"Close".

The last threshold selected is kept in the

memory when the ignition is switched off.

This function, also called automatic emergency

braking, aims to reduce the speed of impact or

avoid a frontal collision with your vehicle where

the driver fails to react.

118

Driving

Using the camera, this function acts on the

vehicle's braking system.

Deactivation/Activation

By default, the system is automatically

activated at every engine start-up.

Deactivation of the system is

With a manual gearbox, in the event of

automatic emergency braking until the

vehicle comes to a complete stop, the

engine may stall.

With an automatic or electronic gearbox,

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

starting off again.

If the camera has confirmed

the presence of a vehicle or a

pedestrian, this warning lamp

flashes once the function is acting

on the vehicle's brakes.

signalled by the illumination of this

indicator lamp, accompanied by the

display of a message.

Important: if operation of the

automatic emergency braking is

triggered, you should take back

control of your vehicle and brake

with the pedal to add to or finish the

automatic braking action.

In the Driving/Vehicle menu

of the touch screen, select the

"Vehicle settings" tab then

"Safety" and activate/deactivate

"Collision risk and auto

braking".

Speciﬁc conditions for operation

The vehicle's speed must be between 3 mph

and 53 mph (5 km/h and 85 km/h) when a

moving vehicle is detected.

The vehicle's speed must not exceed 50 mph

(80 km/h) when a stopped vehicle is detected.

The vehicle's speed must not exceed 37 mph

(60 km/h) when a pedestrian is detected.

The ESC system must not be faulty.

The ASR system must not be deactivated.

All passenger seat belts must be fastened.

impede the function.

The camera may be disrupted or not work

in the following situations:

The driver can take back control of the vehicle

at any time by sharply turning the steering

wheel and/or pressing the accelerator pedal.

poor visibility (inadequate street

lighting, falling snow, heavy rain, dense

fog, etc.),

dazzle (headlamps of an oncoming

vehicle, low sun, reflections on a damp

road, leaving a tunnel, alternating

shade and light, etc.),

The point at which braking is triggered

may be adjusted depending on the driving

actions of the driver, such as movement

of the steering wheel or actions on the

accelerator pedal.

camera obstructed (mud, frost, snow,

condensation, etc.).

On versions with camera alone, this

message indicates to you that the camera

is obstructed: "Driving aids camera:

visibility limited, see user guide".

In these situations, detection performance

may be reduced.

Operation of the function may be felt by

slight vibration in the brake pedal.

If the vehicle comes to a complete stop,

The function has the "Driving time warning"

combined with the "Driver inattention alert".

This alert is issued via the display of a

message encouraging you to take a break,

accompanied by an audible signal.

If the driver does not follow this advice, the

alert is repeated hourly until the vehicle is

stopped.

Do not allow snow to accumulate on the

bonnet or roof of the vehicle as this could

conceal the detection camera.

The system cannot in any circumstances

replace the need for vigilance on the part

of the driver.

Do not take the wheel if you are tired.

The system resets itself if one of the following

conditions is met:

The system is automatically deactivated

after the use of the "space-saver" type

spare wheel is detected, or if a fault with
