Stop and Go adaptive cruise control

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, the system can adapt the speed of your vehicle according to the detected speed limit.
Depending on the vehicle and the country , the system will use the camera and/or the map to adjust the vehicle speed.
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 m. 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 to 99 mph (0 to 160 km/h) according to conditions on the road (traffic, weather etc.).
It is represented by the symbol or .
Note :
  • the driver must observe the maximum speed limit and safe distances in the country where they are driving ;
  • 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.
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 distance 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. Stop and Go adaptive cruise control must only be used on a motorway (or multi-lane road with a central barrier). The cruise control 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.

Location of the camera 1

Make sure the windscreen is not obscured (by dirt, mud, snow, etc.).
WARNING
The camera zones must be kept clean and free of any tampering in order to ensure the proper operation of the system.

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

Switching on

Press the button 5 as many times as necessary to select adaptive cruise control.
The indicator light 9 or appears in grey, and the message “Adaptive Cruise Ctl selected” appears on the instrument panel, accompanied by dashes to indicate that the cruise control function is activated and waiting to store a cruising speed.
This function cannot be activated when :
  • the parking brake is applied ;
  • the Park Assist function is already activated ASSISTED PARKING.
The message "Adaptive Cruise Ctl unavailable" is displayed on the instrument panel.

Activating cruise control

When the vehicle is stationary or moving at a steady speed, press switches 2 (SET/-) or 3 (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 cruise control is confirmed by the appearance of the cruising speed 10 and the indicator light 9 in green.
If you attempt to activate the function at a speed over 99 mph (160 km/h), the message “Invalid Speed” appears and the function remains inactive.
Once a cruising speed is stored 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

If the vehicle is equipped with the "Road Sign Detection" function, the system can manually or automatically adapt the speed of your vehicle according to the detected speed limit.
You can change semi-auto mode and auto mode by pressing and holding the button while the system is activated.
The letter 'A' 13 is displayed on the instrument panel to confirm the activation of the auto mode.
Semi-auto mode
When the new speed limit is detected, the system may propose the detected speed to the driver:
14 with the white square is displayed around the indicated speed to inform.
By pressing the button 4, driver can adapt the vehicle speed to the detected speed.
14 with the green square is displayed around the indicated speed and the cruising speed 10 is set to the detected speed.
Auto mode
If auto mode is selected, the system can manage the automatic adaptation of the cruising speed to the detected speed.
The detected speed 14 is taken into account by the system. The vehicle speed adjusts gragually, until it becomes the cruising speed 10 without any action from the driver.
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 12 is displayed in green on the instrument panel. The default safe distance corresponds to approximately two seconds (see following pages).
If the system detects a vehicle in your lane, an outline of a vehicle 11 appears above the distance gauge 12 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 10 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 (for low variation) or pressing and holding (for high variation) switch 2 or 3 :
  • use the “SET/-" switch 2 to reduce the speed ;
  • use the “SET/+" switch 3 to increase the speed.

Adjusting the following distance

You can vary the safe distance from the vehicle in front at any time by pressing switch 5 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 2 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 safe distance is adjusted by default on the distance gauge B.

Exceeding the cruising speed

The cruising speed may be exceeded at any time by applying the accelerator pedal.
If it is exceeded, the cruising speed 10 appears in yellow.
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, activating the indicator will temporarily cancel the safe distance control and enable an acceleration speed sufficient to complete overtaking.

Stop and start

If the vehicle in front slows down the system adapts its speed, to a complete stop if necessary (in the event of a traffic jam, etc). 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 sets off again :
  • If the stop does not exceed about thirty seconds the vehicle sets off automatically without any action by the driver ;
  • if the stop exceeds about three seconds, you must apply the accelerator pedal or press button 8 (RES) in order for the vehicle to set off again. The message "Press RES or accelerate to restart Cruise Control” appears on the instrument panel to confirm.
Note
the 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 about three minutes, the electronic parking brake is automatically applied and the Stop and Go adaptive cruise control is deactivated. The or indicator light 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 put the gearbox in P, R or N ;
  • you unbuckle the driver’s seatbelt ;
  • 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, etc.).
In all circumstances, the standby is confirmed when the warning lights appear in grey and the message “Adaptive Cruise Ctl Disconnected” appears on the instrument panel.
WARNING
Putting the Stop and Go adaptive cruise control on 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

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) in the range of confirmed speeds.
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
When the cruise control is set to standby, pressing switch 2 (SET/-) or 3 (SET/+) reactivates the cruise control function without taking into account the stored speed : it is the speed at which the vehicle is moving that is taken into account.

“Take control of the vehicle” warnings

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 message “Brake”, 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 deactivated when you press switch 6.
The warning light or disappears from the instrument panel to confirm that the function is no longer active.

Temporary unavailability

The green warning light or disappears to confirm that the function has been automatically deactivated.
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.
Note
The system controls acceleration and deceleration of your vehicle using the engine and braking system. The system activates the brakes in order to maintain the set speed, the system applies limited braking. In the event of a steep descent, for example in a mountainous area, you must select a lower gear to benefit from engine braking.
To reduce the load imposed on the braking system and to prevent the brakes from overheating, the adaptive cruise control function may be temporarily interrupted and the "Check adaptive cruise control" message appears. The message disappears when the function becomes available again.
If the message remains, contact an approved dealer.

Operating faults

If an operating fault is detected on one or more components of the system, the Stop and Go adaptive cruise control function is interrupted.
The warning light appears on the instrument panel along with, depending on the malfunction, one of the following messages :
  • “Check Front camera” ;
  • “Check camera/Radar” ;
  • "Check vehicle".
Consult an approved dealer.

Limitations of system operation

Vehicle detection
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. G) will be taken into account by the system only once it enters the camera detection areas.
The system may trigger abrupt or delayed braking.
The system cannot detect :
  • vehicles arriving at intersections : slip road (e.g. H) etc ;
Tip
The Stop and Go adaptive cruise control function must only be used outside built-up areas, on wide roads with visible lines.
  • vehicles driving on the wrong side of the road or reversing towards you.
Detection during cornering
When entering a corner or bend, the camera may temporarily not be able to detect the vehicle in front (e.g. 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 inappropriate 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 (e.g. 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.
Vehicles hidden due to variations in ground relief
The system will not detect vehicles hidden due to variations in ground relief or those located outside of the camera detection areas when driving uphill or downhill.
Vehicles outside the camera detection areas.
The system will react late or not at all if the detected vehicles are outside the camera detection areas, particularly in the following cases :
  • vehicles transporting long objects which exceed the line ;
  • the actual length of tall vehicles (e.g. L) outside the camera detection area (construction machine, agricultural equipment towing vehicle, etc.) ;
  • vehicles insufficiently centred in the lane ;
  • narrow vehicles which are very close (e.g. M).
Stationary and slow moving vehicles
When your speed is over approximately 31 mph (50 km/h), the system does not detect :
  • stationary vehicles (e.g 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 (e.g N) ;
  • very slow moving vehicles ;
  • vehicles in front 12 which change lane, revealing a stationary vehicle 13 (e.g. P).
  • when the vehicle is stationary 14, when you change lane (e.g. Q).
Tip
Always be ready to take control of your vehicle when you come upon stationary or very slow moving vehicles (e.g. N).
The Stop and Go 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, bikes, scooters, etc. ;
  • animals ;
  • fixed obstacles (toll barriers, walls, etc.) (e.g. R).
These are not taken into account by the system. They do not trigger any alert or reaction by the system.
Detection of vehicles moving into lane at high speed
If your vehicle is overtaken by another vehicle driving at high speed 15 (motorcycle, car, etc.) and the vehicle is temporarily between you and the vehicle in front 16, the system may trigger undue acceleration, slowing or braking.
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.
Apart from the speed limit signs and road map information from the mapping (vehicles fitted with the "Road sign detection" function and a subscription), other traffic information (traffic lights, pedestrian crossings, etc.) is not taken into account by the system. The driver must always adapt their speed to the surroundings and driving conditions, regardless of system indications.
The system should under no circumstances be taken to be an obstacle detector or an anti-collision system.
Use the adaptive cruise control Stop and Go outside built-up areas, on wide roads with visible lines.
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 proximity of the camera (replacements, repairs, windscreen modifications, paintwork 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 being towed (breakdown recovery) ;
  • the vehicle is towing a trailer or a caravan ;
  • 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 driven on a very winding road (mountain road, etc.) ;
  • 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. interior or exterior windscreen area) ;
  • the windscreen is cracked or distorted.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
WARNING
In the event of system disturbance
Some conditions can disturb or damage the operation of the system, such as :
  • the windscreen is obscured in the area of the camera (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.) ;
  • 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 prefitted 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 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.
