road.

hail).

– Your vehicle is not pulling a trailer, a caravan,

etc.

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.

Driving

This system:

The vehicle has a multifunction camera located

at the top of the windscreen and, depending on

version, a radar located in the front bumper.

Stabilised speed on roads with few bends.

In the following cases, deactivating the system

via the vehicle's configuration menu is advised:

– Towing a trailer.

– warns the driver that their vehicle is at risk of

collision with the vehicle in front, a pedestrian or,

depending on version, a cyclist.

This system does not replace the need for

vigilance on the part of the driver.

– reduces the vehicle's speed to avoid a collision

or limit its severity.

– Carrying long objects on roof bars.

– Vehicle with snow chains fitted.

– Before using an automatic car wash, with the

engine running.

This system is designed to assist the driver

and improve road safety.

The speed will be reduced by a maximum

of 16 mph (25 km/h) for versions with

camera only, or by a maximum of 31 mph

(50 km/h) for versions with camera and radar.

– Towed vehicle, engine running.

– Following an impact to the windscreen close to

the detection camera.

The system also takes motorcyclists into

account.

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.

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.

This system is comprised of three functions:

– Collision Risk Alert.

– Intelligent emergency braking assistance

(iEBA).

Deactivation/Activation

By default, the system is automatically activated

– Active Safety Brake (automatic emergency

braking).

It can be dangerous to drive if the brake

lamps are not in perfect working order.

at every engine start.

The settings are changed via the

Driving/Vehicle touch screen menu.

Deactivation of the system is signalled by

the illumination of this warning lamp,

accompanied by the display of a message.

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.

Operating conditions and limits

Vehicle moving forward.

Following an impact, the system is

automatically deactivated.

Collision Risk Alert

Active Safety Brake

This function warns the driver that their vehicle

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

with a pedestrian or cyclist present in their traffic

lane.

Level 2: visual and audible alert, warning

you 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.

Modifying the alert trigger threshold

This trigger threshold determines the sensitivity

with which the function warns of the risk of

collision.

Where the speed of your vehicle is too

high approaching another vehicle, the

touch screen menu.

first level of alert may not be displayed: the

level 2 alert may be displayed directly.

►ꢀ Select one of the three pre-defined thresholds:

"Far", "Normal" or "Close".

Important: the level 1 alert is not displayed

when there is a stationary obstacle or when

the "Near" trigger threshold has been selected.

The last threshold selected is memorised when

the ignition is switched off.

Intelligent emergency braking

assistance (iEBA)

This function supplements braking in the event

that the driver brakes, but not enough to avoid a

collision.

Operation

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.

Depending on the degree of risk of collision

detected by the system and the alert trigger

threshold chosen by the driver, several different

levels of alert may be triggered and displayed on

the instrument panel.

The system aims to reduce the speed of impact or

avoid a collision where the driver fails to react.

This assistance will only be provided if the driver

presses the brake pedal.

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,

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

most relevant moment.

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).

Operation

Level 1: visual alert only, warning you that

the vehicle in front is very close.

The system operates subject to the following

conditions:

128

Driving

– At reduced speed in an urban environment,

when a stationary vehicle, pedestrian or cyclist is

detected.

Have it checked by a dealer or a qualified

workshop.

In certain driving conditions (poor road

surface or strong winds), the system may

give alerts independent of the driver's level of

vigilance.

If these warning lamps come on

– 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.

after the engine has been switched

off and then restarted, contact a dealer or a

qualified workshop to have the system checked.

These warning lamps light up on

The following situations may interfere

with the operation of the system or

prevent it from working:

the instrument panel to indicate

function applies the vehicle’s brakes.

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.

– close to the vehicle ahead (lane markings

not detected);

– roads that are narrow, winding, etc.

Distraction detection

Activation/Deactivation

For more information, refer to the General

recommendations on the use of driving

and manoeuvring aids.

The driver can maintain control of the

vehicle at any time by firmly turning the

steering wheel and/or firmly depressing the

accelerator pedal.

This function is set via the touch screen

Driving/Vehicle menu.

The state of the system is memorised when the

ignition is switched off.

The function comprises the "Driver Attention

Warning" and "Driver Attention Warning by

Camera" systems, combined, depending on

version, with the "DS DRIVER ATTENTION

MONITORING" system.

The brake pedal may vibrate slightly while

the function is operating.

Driver Attention Warning

The system triggers an alert when it

detects that the driver has not taken a

break after two hours of driving at a speed above

43 mph (70 km/h).

If the vehicle comes to a complete stop,

automatic braking is maintained for 1 to 2

seconds.

These systems are in no way designed to

keep the driver awake or to prevent the

driver from falling asleep at the wheel.

It is the driver’s responsibility to stop if feeling

tired.

This alert is issued via the display of a message

encouraging the driver to take a break,

accompanied by an audible signal.

Malfunction

In the event of a malfunction, this warning

lamp lights up on the instrument panel,

accompanied by the display of a message and an

audible signal.

If the driver does not follow this advice, the alert

is repeated hourly until the vehicle is stopped.

The system resets itself if one of the following

conditions is met:

Take a break if you are feeling tired or at least

every 2 hours.
