Based on information from a camera, the Stop and Go adaptive cruise control function gives you the option of maintaining a selected speed, known as the cruising speed, while keeping a safe distance from the vehicle in front in the same lane.

Depending on the vehicle, when the "Road sign detection" function is activated Detection of road signs, the system can adapt the speed of your vehicle according to the speed limit signs recognised by the camera.

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 system controls acceleration and deceleration of your vehicle using the engine and braking system.

The system's maximum range is approximately 140 metres. This may vary according to the road conditions (ground relief, weather conditions, etc.)

The Stop and Go adaptive cruise control function can be activated from 0 km/h to 99 mph (0 to 160 km/h).

The function is indicated by the symbol.

Note:

  • the driver must observe the maximum speed limit and safe distances according to the legislation in the country where they are driving;
  • the Stop and Go 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.
tip

The Stop and Go adaptive cruise control does not trigger an emergency stop and its braking capability is limited.

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.

The driver must always adapt their speed according to the surroundings and traffic conditions.

Use the adaptive cruise control outside built-up areas, on wide roads with visible lines.

The cruise control may have limited operation on very winding or slippery roads (black ice, aquaplaning, gravel) or during bad weather (fog, rain, side winds, etc.)

There is a risk of accidents.

warning

The camera should be kept clean and free of any modifications in order to ensure the proper operation of the system.

Switching on

Press switch 6 as many times as required to select the adaptive cruise control Stop and Go.

The warning light 9 2_ALL_496_1_pictogramme.png appears in grey and the "Adaptive Cruise Ctl selected" message appears on the instrument panel accompanied by dashes to indicate that the function is activated and waiting to store a cruising speed.

This function cannot be activated when:

The "Adaptive Cruise Ctl unavailable" message is displayed on the instrument panel.

Activating cruise control

With the vehicle stationary or moving at a steady speed, press switch 3 (SET/+) or 2 (SET/˗) to activate the function and store the current speed.

The minimum cruising speed is 19 mph (30 km/h).

The cruising speed 10 replaces the dashes and the cruise control operation is confirmed by the appearance of the cruising speed in green and warning light 9 2_ALL_496_1_pictogramme.png .

If you attempt to activate the function at a speed over 99 mph (160 km/h), the "Invalid Speed" message appears and the function remains deactivated.

Once a cruising speed is memorised and the cruise control function is active, you may lift your foot off the accelerator pedal.

Note: if your vehicle speed is lower than about 19 mph (30 km/h), the function uses a default cruising speed of 19 mph (30 km/h). The vehicle will accelerate until it reaches the stored cruising speed.

warning

Important: you should keep your feet near the pedals at all times to prepare for any event.

Activating cruise control with speed limit sign recognition

12049_P1310_025_1_image.jpeg

If the vehicle is equipped with the "Road sign detection" function Detection of road signs, press the switch 4 to adapt the vehicle's speed to the speed limits 13 detected by the camera.

When passing the sign, the cruising speed 10 adopts the value of the detected speed 13.

The driver must always stay vigilant regarding the speed applied by the system and remains responsible for the vehicle speed.

Safe distance control activation

As soon as cruise control is activated, the default safe distance 11 is displayed in green on the instrument panel.

The following distance setting is stored by the system between each activation of Adaptive Cruise Control and for the next vehicle start cycle.

If the system detects a vehicle in your lane, an outline of a vehicle 12 appears above the distance gauge 11 on the instrument panel.

Your vehicle adapts its speed to that of the vehicle in front and applies the brakes if necessary (the brake lights come on) in order to maintain the distance displayed on the instrument panel.

Note: the size of the 12 outline varies according to the distance separating you from the vehicle in front. The larger the outline, the closer the vehicle in front.

Setting the cruising speed

You can vary the speed by repeatedly pressing (small increments) or pressing and holding (large increments) switch 2 or 3:

  • switch (SET/˗) 2 to reduce the speed;
  • switch (SET/+) 3 to increase the speed.

Adjusting the following distance

12049_P1310_003_1_image.jpeg

You can vary the safe distance from the vehicle in front at any time by pressing switch 7 repeatedly.

The horizontal distance gauge on the instrument panel indicates the various available safe distances:

  • distance gauge A: long distance (corresponding to approximately 2.4 seconds);
  • distance gauge B: intermediate distance 2 (corresponding to approximately two seconds);
  • distance gauge C: intermediate distance 1 (corresponding to approximately 1.6 seconds);
  • distance gauge D: short distance (corresponding to approximately 1.2 seconds).

The selected distance gauge appears in green on the instrument panel.

The other gauges remain in grey.

Note: the distance must be set according to the traffic level, local regulation and weather conditions.

tip

The following distance setting is stored by the system between each activation of Adaptive Cruise Control Stop and Go and for the next vehicle start cycle.

Exceeding the cruising speed

12049_P1310_026_1_image.jpeg

The cruising speed may be exceeded at any time by applying the accelerator pedal.

If it is exceeded, the cruising speed 10 appears in red.

The distance gauge flashes if the distance between your vehicle and the vehicle in front is less than the safe distance selected: the "Safe Distance Control" function is no longer active.

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.

Overtaking manoeuvre

If you wish to overtake the vehicle in front of you, activating the direction indicator temporarily cancels the safe distance control and allows sufficient acceleration speed for overtaking.

Stop and start

If the vehicle in front slows down, the system adapts its speed to bring the vehicle to a complete stop if necessary (e.g. in heavy traffic). The vehicle stops a few metres from the vehicle in front. The Stop and Start function can put the engine on standby Stop and Start function.

When the vehicle in front moves off again:

  • if the stop does not exceed approximately thirty seconds, the vehicle sets off automatically without any action by the driver;

Note: the driver should always be ready for sudden incidents while driving 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 stop exceeds approximately thirty seconds, you must press the accelerator pedal or press switch 8 (RES) in order for the vehicle to set off again. The "Press RES or accelerate to restart Cruise Control" message appears on the instrument panel to confirm this.

If the stop exceeds about three minutes, the electronic parking brake is automatically applied and the Stop and Go adaptive cruise control is deactivated.

The warning light 9 2_ALL_496_1_pictogramme.png goes out to confirm that the function is deactivated.

Putting the function on standby

You can set the function to standby when:

  • you press switch 5 (0);
  • you apply the brake pedal while the vehicle is moving.

The function is deactivated by the system if:

  • you set the gearbox to P, R or N ;
  • you unbuckle the driver's seat belt;
  • you open one of the opening elements;
  • you press the engine start/stop button;
  • the slope is too steep;
  • the vehicle speed is above 106 mph (170 km/h;
  • certain driving aids and correction devices are triggered (active emergency braking, ABS, ESC.)

In all circumstances, the standby is confirmed when the warning lights appear in grey and the message "Adaptive Cruise Control disconnected" appears on the instrument panel.

warning

Putting the Stop and Go adaptive cruise control in standby or switching it off does not cause a rapid reduction in speed: you must brake by applying the brake pedal if necessary.

Exit from standby

  • The parking brake is applied.
  • The "Active Emergency Braking" function triggers braking.
  • The sensor is obstructed (camera blindness detected).

Based on the stored cruising speed

If a speed is stored, it can be recalled, once you are sure that the road conditions are suitable (traffic, road surface, weather conditions, etc.).

Press switch 8 (RES) within the valid speed range. When the stored speed is recalled, activation of the cruise control is confirmed by the illumination of the cruising speed in green.

Note: if the stored speed is higher than the current speed, the vehicle will accelerate to reach that speed.

Based on the current speed

With the cruise control function on standby, pressing switch 2 (SET/˗) or 3 (SET/+) reactivates the cruise control function without taking into account the stored speed: it is the vehicle's current speed that is taken into account.

"Take control of the vehicle" warnings

12049_P1310_005_1_image.jpeg

In some situations (e.g. coming upon a much slower vehicle, vehicle in front changing lanes quickly, etc.) the system may not have time to react.

Depending on the situation, the system sounds a beep associated with:

  • the orange alert E if the situation requires the driver's attention;

or

  • the red alert F accompanied by the "Brake" message if the situation requires the driver's immediate attention.

In all situations, react accordingly and perform the appropriate manoeuvres.

Switching off the function

The "Stop and Go adaptive cruise control" function is interrupted when you press switch 6. In this case, the speed is no longer stored.

The warning light 9 2_ALL_496_1_pictogramme.png disappears from the instrument panel to confirm that the function is no longer active.

tip

In this case, the next time the engine is started, the "Speed limiter" function will be activated and waiting for a speed limit to be stored.

Temporarily not available

The grey warning light 9 2_ALL_496_1_pictogramme.png disappears to confirm that the function has been automatically deactivated.

Ensure that the camera area has not been obscured (by dirt, mud, snow, etc. ) or subject to an impact.

Conditions in certain geographical areas may hinder the function, for example:

  • arid zones, tunnels, long bridges or lightly used roads without road lines, without signs or trees nearby;
  • a military or airport zone.

You must leave such areas in order for the function to work.

In all cases, if the message is not erased after the engine is restarted, please contact an authorised dealer.

Operating faults

If an operating fault is detected for the "Stop and Go adaptive cruise control" function, the "Check Adaptive Cruise Control" message appears on the instrument panel and the "Stop and Go adaptive cruise control" function is interrupted.

If an operating fault is detected on one or more components of the system, the "Stop and Go adaptive cruise control" function is interrupted.

Depending on the type of malfunction, the message is displayed on the instrument panel:

  • Check Front camera accompanied, depending on the vehicle, by the 1_ALL_036_1_pictogramme.png  warning light;
  • Check vehicle accompanied, depending on the vehicle, by the 1_ALL_036_1_pictogramme.png  warning light;
  • Check Camera/Radar.

Consult an approved Dealer.

Limitations of system operation

12049_P1310_006_1_image.jpeg

Vehicle detection

The system detects only vehicles (cars, trucks, motorbikes) that are moving in the same direction as your vehicle.

A vehicle moving into the same lane (example G) will be taken into account by the system only once it has completely entered the camera detection zones.

The system may trigger abrupt or delayed braking.

The system cannot detect:

  • vehicles arriving at intersections: slip road (example H);
  • vehicles driving on the wrong side of the road or reversing towards you.
tip

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

12049_P1310_008_1_image.jpeg

Detection during cornering

When entering a corner or bend, the camera may temporarily be unable to detect the vehicle in front (example J).

The system may trigger an acceleration.

When exiting a bend, the system's detection of the vehicle in front may be disrupted or delayed.

The system may trigger abrupt or delayed braking.

Detection of vehicles in adjacent lanes

The system may detect vehicles driving on an adjacent lane when:

  • you drive into a bend (example K);
  • you are driving on a road with narrow lanes;
  • the speed of the vehicle on the adjacent 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.

12049_P1310_010_1_image.jpeg

Vehicles hidden due to variations in ground relief

The system will not register vehicles driving uphill or downhill when hidden by terrain or when located outside the camera's detection zones.

Vehicles outside the camera detection zones

The system will react late or not at all if detected vehicles are outside the camera detection zones, particularly in the following situations:

  • vehicles transporting long objects which exceed the line;
  • vehicles insufficiently centred in the lane;
  • narrow vehicles which are very close (example M).

12049_P1310_012_1_image.jpeg

Stationary and slow moving vehicles

When your speed is over approximately 31 mph (50 km/h), the system does not detect:

  • stationary vehicles (example N);
  • very slow moving vehicles.

When your speed is less than approximately 31 mph (50 km/h), the system may not react or may react very late to:

  • stationary vehicles (example N);
  • very slow moving vehicles;

  • preceding vehicles 14 that change lane or discovering a slow or stationary vehicle 15 (example P);
  • stationary or slow vehicles 16, when you change lane (example Q).

12049_P1310_014_1_image.jpeg

tip

Always be ready to take control of your vehicle when you come upon stationary or very slow-moving vehicles (example N).

The adaptive cruise control does not trigger an emergency stop and its braking capability is limited.

Non-detection of fixed obstacles and objects of a small size

The system cannot detect:

  • pedestrians, bicycles, scooters, shopping trolleys, caddies, etc.;
  • animals;
  • fixed obstacles (toll barriers, walls, etc.) (example R).

These are not taken into account by the system.

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

12049_P1310_016_1_image.jpeg

Detection of vehicles moving into lane at high speed

If your vehicle is overtaken by another vehicle driving at high speed 17 (motorcycle, car, etc.) and the vehicle is temporarily between you and the vehicle in front 18, the system may trigger undue acceleration, slowing or braking.

Warning

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.

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 camera alignment may be changed and its operation may consequently be affected. Deactivate the system and consult an authorised dealer.
  • Any work in the area where the camera is located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.

Only an authorised dealer is qualified to service the system.

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;
  • 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 camera area has been damaged (e.g. on the inside or outside of the windscreen);
  • the windscreen is cracked or distorted.

In the event of the system behaving abnormally, deactivate it and contact an authorised dealer.

warning

In the event of system disturbance

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

  • windscreen obscured (by dirt, ice, snow, etc.);
  • poor weather conditions (snow, heavy rain, hail, black ice, etc.);
  • poor visibility (night, fog, etc.);
  • 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 appear in the camera detection zone may be interpreted by the system incorrectly, possibly leading to inappropriate acceleration 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.
