ADAPTIVE CRUISE CONTROL

Deactivating the function

You must deactivate the function if:

– the vehicle is travelling on a winding road;

– the vehicle is being towed (breakdowns);

– the vehicle is towing a trailer or a caravan;

3

– the vehicle is being driven in a tunnel or close to a metallic structure;

– the vehicle arrives at a toll point, a roadwork area or on a narrow lane;

– the vehicle is being driven up or down a very steep slope;

– the visibility is poor (glaring sun, fog, etc.);

– the vehicle is being driven on a slippery road surface (rain, snow, gravel, etc.);

– the weather conditions are poor (rain, snow, side winds, etc.);

– the radar area has been damaged (impacts, etc.);

– the camera area has been damaged (e.g. on the inside or outside of the windscreen);

ADAPTIVE CRUISE CONTROL

In the event of system disturbance

Some conditions can disturb or damage the system's operation, such as:

–

the windscreen or the radar area is obscured (by dirt, ice, snow, condensation, number plate, etc.);

– a complex environment (tunnel, etc.);

– poor weather conditions (snow, heavy rain, hail, black ice, etc.);

– poor visibility (night, fog, etc.);

3

– poor contrast between the vehicle preceding it and the surrounding area (e.g. white vehicle in a snowy area, etc.);

– being dazzled (glaring sun, lights of vehicles travelling in the opposite direction; etc.);

– narrow, winding or undulating road (tight bends, etc.);

– a slower vehicle with a significant difference in speed;

– use of mats not adapted to the vehicle. On the driver's side, only use mats suitable for the vehicle, attached with

the pre-fitted components, and check the fitting regularly. Do not lay one mat on top of another. There is a risk of

wedging the pedals.

In these cases, the system may wrongly intervene.

Risk of unwanted braking or acceleration.

Many unforeseen situations may affect the system operation. Certain objects or vehicles that can appear in the

camera or radar detection zone may be interpreted by the system incorrectly, possibly leading to inappropriate ac-

celeration or braking.

You should always be attentive to sudden events that might occur while you are driving. Always keep your vehicle

under control by keeping your feet near the pedals, so that you are ready to act in any event.

ACTIVE DRIVER ASSIST

(depending on the country and sub-

scription).

If the vehicle in front stops, the Stop

and Go adaptive cruise control may

brake your vehicle to a complete

stop before setting off again.

– the adaptive cruise control can

brake the vehicle up to a third of the

braking capacity. Depending on the

situation, the driver may need to

brake harder.

The "Active driver assist" system is a

driving aid for use outside urban ar-

eas, on wide roads with visible lines.

This system consists of the "Adap-

tive cruise controlStop and Go"

function ꢀ 234 and the "Lane Cen-

tring" function.

This system enables the driver to:

– maintain vehicle speed based on a

previously stored speed;

– adjust the distance between their

vehicle and the vehicle in front;

– direct the trajectory of the vehicle

in the lane;

– adapt the vehicle speed to the

speed shown on the road signs, au-

tomatically or after confirmation by

the driver (depending on the vehi-

cle).

3

The Stop and Go adaptive

cruise control does not

trigger an emergency

stop and its braking capability

is limited.

Important: you should

keep your feet near the

pedals and your hands

on the steering wheel

at all times to prepare for any

event.

The "Lane Centring" function

Using information from a camera,

the "Lane Centring" function manip-

ulates the steering system to direct

the vehicle in the lane.

The system controls acceleration

and deceleration of your vehicle us-

ing the engine and braking system.

The Stop and Go adaptive cruise

control function can be activated

from 0 to 112 mph (180 km/h), de-

pending on the vehicle and accord-

ing to road conditions (traffic,

weather, etc.).

If the conditions allow it, the function

is available between:

– 0 mph and a speed between 99

mph (160 km/h) and 112 mph (180 km/

h) (depending on the version) with a

vehicle in front;

The "Stop and Go adaptive

cruise control" function.

Depending on the country and sub-

scription, based on information from

a radar, camera or map data sent

via a GSM connection, the Stop and

Go adaptive cruise control makes it

possible to maintain a selected

speed, known as the cruising speed,

while keeping a safe distance from

the vehicle in front in the same lane.

– 37 mph (60 km/h) and a speed be-

tween 99 mph (160 km/h) and 112

mph (180 km/h) (depending on the

version) without a vehicle in front.

The "Lane Centring" function is a

comfort feature.

Note:

– the driver must observe the maxi-

mum speed limit and safe distances

according to the legislation in the

country where they are driving;

The cruising speed can adjust auto-

matically to a speed limit change

Note: in the event of a sharp bend,

the function's lateral retention ca-

pacities are limited and require the

driver to take immediate action on

the steering wheel.

Additional information

Depending on the vehicle, the "Ac-

tive driver assist" function can be

used with other driving aid functions.

Please note that:

– When the "Lane Centring" func-

tion is in adjustment mode, this will

suspend the "Lane departure pre-

vention" function if it has already

been activated. When the "Lane

Centring" function is not controlling

the steering system, the "Lane de-

parture prevention" function may be

reactivated if conditions allow.

1 Camera

Keeps the vehicle stationary under

certain conditions.

Detects markings on the ground and

the position of vehicles on the vari-

ous traffic lanes.

4 Power-assisted steering

The radar and camera

zones must be kept

clean and free of any

tampering in order to

ensure the proper operation of

the system.

It operates the front wheels to guide

the vehicle trajectory according to

the information transmitted by the

camera 1 . It also enables detection

of the driver's hands on the steering

wheel.

It receives information from the

radar 6 and merges it with its own

information to determine the trajec-

tory and speed of the vehicle (accel-

eration/braking). Amongst other

things, it controls the system activa-

tion/deactivation parameters (door

opening status, etc.).

Depending on the vehicle, it process-

es information to detect the pres-

ence of the driver's hands on the

steering wheel.

3

5 Engine computer

It controls and directs the engine to

carry out the required acceleration.

6 Radar

Calculates the distance between

your vehicle and the vehicle in front.

The system's maximum range is ap-

proximately 150 metres. This may

vary according to the road condi-

tions (ground relief, weather condi-

tions, etc.)

Ensure that the radar area is not ob-

structed (dirt, mud, snow, a badly fit-

ted front number plate), impacted,

modified (including painting) or hid-

den by any accessory fitted on the

front of the vehicle (on the grille or

logo etc.).

Make sure the windscreen is not ob-

scured (by dirt, mud, snow, etc.).

2 Aerial and maps

(depending on the country and sub-

scription)

Road maps and certain driving con-

ditions (roundabouts and cornering)

are downloaded according to the

journey taken by the vehicle. The

system can anticipate deceleration

following a change of the speed limit

indicated on road signs, depending

on the parameters selected by the

driver.

7 Active vehicle control

The system can also adjust the

vehicle's speed when approaching a

bend or roundabout.

This system supplies information on

vehicle dynamics to the camera 1

(speed, lateral acceleration, etc.)

and acts on the braking system to

ACTIVE DRIVER ASSIST

Warning

The "Active driver assist" is an additional driving aid. it can under no circumstances replace the driver's re-

sponsibility to respect speed limits and safe distances and to be vigilant.

The driver must always be in control of the vehicle.

The driver must always adapt their trajectory and speed according to the surroundings and driving condi-

tions, regardless of system indications.

3

Except for lines delimiting lanes and the speed limit signs within the limits of the system's detection capacity, the

road sign information (other traffic signs, traffic lights, pedestrian crossings, etc.) are not recognised by the system.

These do not trigger any alert or reaction by the system.

The "Active driver assist" uses the "Stop and Go "adaptive cruise control" and "Lane centering assist." functions.

The system should under no circumstances be taken to be an obstacle detector or an anti-collision system.

Use the "Active driver assist" exclusively outside built-up areas, on wide roads with visible lines.

It must not be used in heavy traffic, on winding or slippery roads (black ice, aquaplaning, gravel) or during bad

weather (fog, rain, side winds etc.).

There is a risk of accidents.

System servicing/repairs

– In the event of an impact, the radar and/or camera alignment may be changed and its operation may conse-

quently be affected. Deactivate the system and consult an authorised dealer.

– Any work in the proximity of the radar and/or camera (replacements, repairs, windscreen modifications, paint-

work etc.) must be carried out by a qualified professional.

Only an authorised dealer is qualified to service the system.

Some conditions can disrupt or damage the system operation, for example:

obstruction of the windscreen or the radar area (by dirt, ice, snow, condensation etc.) Frequently check

–

the cleanliness and condition of the windscreen, front wiper blades and front bumper;

– a complex environment (tunnel, etc.);

– poor weather conditions (snow, heavy rain, hail, black ice, etc.);

– poor visibility (night, fog, etc.);

3

– poor contrast between the vehicle preceding it and the surrounding area (e.g. white vehicle in a snowy area, etc.);

– being dazzled (glaring sun, lights of vehicles travelling in the opposite direction; etc.);

– narrow, winding or undulating road (tight bends, etc.);

– the tar lines detected as a line by the system;

– narrowing/widening lanes;

– multiple road markings (roadworks, etc.) ; the road lines are irregular or difficult to distinguish (e.g. partially erased

markings, excessive spacing, uneven road surface, etc.);

– road signs that do not include an arrow, located on a motorway exit;

– an area with low connectivity that makes it impossible to geolocate the vehicle, or maps that are not up-to-date;

– a vehicle with a significant difference in speed;

– use of mats not adapted to the vehicle. On the driver's side, only use mats suitable for the vehicle, attached with

the pre-fitted components, and check the fitting regularly. Do not lay one mat on top of another. There is a risk of

wedging the pedals.

In these cases:

–

Risk of unwanted braking or acceleration.

Risk of unwanted, incorrect correction or no correction of trajectory.

Many unforeseen situations may affect the system operation. Certain objects or vehicles that can appear in the

camera or radar detection zone may be interpreted by the system incorrectly, possibly leading to inappropriate ac-

celeration or braking.

You should always be attentive to sudden events that might occur while you are driving. Always maintain your vehi-

cle under control by keeping your feet near the pedals and your hands on the steering wheel, so that you are ready

to act in any event.
