vary according to the road condi-

tions (ground relief, weather condi-

tions, etc.)

The "Adaptive cruise control" func-

tion can be activated from 0 mph (0

km/h), depending on conditions on

the road (traffic, weather, etc.).

Depending on the country and sub-

scription, the system will use the

camera and the map to adjust the

vehicle speed in advance according

to the context and road incidents

(roundabouts, bends, upcoming

road signs or speed limit zones).

If the vehicle in front stops, the Stop

and Go adaptive cruise control may

brake your vehicle to a complete

stop before allowing the vehicle to

move on again.

The system controls acceleration

and deceleration of your vehicle us-

ing the engine and braking system.

The system's maximum range is ap-

proximately 130 metres. This may

vary according to the road condi-

tions (ground relief, weather condi-

tions, etc.)

Based on information from a radar

or camera, the adaptive cruise con-

trol function (or the Stop and Go

adaptive cruise control function on

vehicles equipped with an automat-

ic gearbox) enables you to maintain

the speed selected, known as the

cruising speed, while keeping a fol-

lowing distance with the vehicle in

front in the same lane.

Depending on the vehicle, when the

"Road Sign Detection" function is

activated ꢀ 217, the system can

adapt the speed of your vehicle ac-

cording to the speed limit signs rec-

ognized by the camera.

Depending on the country and sub-

scription, the system will use the

The cruising speed may be exceed-

ed at any time by applying the accel-

erator pedal.

During overtaking, the cruising

speed 13 is displayed in yellow: the

"Distance Control" function is no

longer ensured.

Then, release the accelerator pedal:

the cruise control and safe distance

control will automatically resume

the speed and distance instructions

that you had previously selected.

Note: the driver should always be

ready for sudden incidents while dri-

ving and remains responsible for

controlling the vehicle: if the system

detects a pedestrian in the area

around the vehicle, the automatic

restart will be inhibited until the next

stop;

– if the stopping time exceeds ap-

proximately thirty seconds, for the

vehicle to set off again it is neces-

sary to either:

– you apply the brake pedal while

the vehicle is moving.

The function is deactivated by the

system if:

– you set the automatic gearbox to

P or N;

– you engage the reverse gear;

– you unbuckle the driver's seat belt;

– you open one of the opening ele-

ments;

– you press the engine start/stop

button;

The two functions are automatically

reactivated as soon as reception of

the connected data becomes opti-

mal again.

Overtaking manoeuvre

If you want to overtake the vehicle in

front and your speed is over 43 mph

(70 km/h) only, activating the direc-

tion indicators temporarily reduces

the following distance and triggers

acceleration to facilitate overtaking.

Stop and start

If the vehicle in front slows down, the

system adapts its speed, if neces-

sary to a complete stop (e.g. in heavy

traffic). The vehicle stops a few me-

tres from the vehicle in front.

– vehicles driving on the wrong side

of the road or reversing towards you.

When entering a corner or bend, the

radar and/or camera may be tem-

porarily unable to detect the vehicle

in front (e.g. M ).

The system may trigger an acceler-

ation.

When exiting a bend, the system's

detection of the vehicle in front may

be disrupted or delayed.

The system detects only vehicles

(cars, trucks, motorbikes) that are

moving in the same direction as your

vehicle.

A vehicle turning into the same lane

(e.g. K ) will be taken into account by

the system only once it enters the

tural equipment towing vehicle, etc.);

– vehicles insufficiently centred in

the lane;

The system may detect vehicles dri-

ving on an adjacent lane when:

– you drive into a bend (example N );

– you are driving on a road with nar-

row lanes;

– the speed of the vehicle on the ad-

jacent lane is slower and if one of

these vehicles is located too close to

the lane of the other.

The system may incorrectly trigger

vehicle slowing or braking.

– narrow vehicles which are very

close (e.g. Q ).

ADAPTIVE CRUISE CONTROL

Warning

This function is an additional driving aid. It can under no circumstances replace the driver's responsibility to

respect speed limits and safe distances or to be vigilant.

The driver must always be in control of the vehicle.

3

The driver must always adapt their speed to the surroundings and driving conditions, regardless of system

indications. Except for lines delimiting lanes, traffic indicators (traffic lights, signs, pedestrian crossings etc.) are not

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

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

The adaptive cruise control must only be used on a motorway (or multi-lane road separated by a barrier).

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.
