ACTIVE EMERGENCY BRAKING
The system uses information from the radar 2 and the camera 1 to determine the distance from your vehicle:
- from the vehicle ahead in the same lane;
or
- surrounding pedestrians and cyclists.
The system informs the driver if there is a risk of head-on collision to enable appropriate emergency manoeuvres (pressing the brake pedal and/or turning the steering wheel).
Depending on the reactivity of the driver, the system can assist with braking in order to limit damage or prevent a collision.
Note: ensure that the windscreen and front bumper are not obstructed (by dirt, mud, snow, condensation, number plate, etc.).
This system can apply maximum braking to the vehicle until it is completely stationary if necessary.
For safety reasons, always wear your seat belt when travelling in your vehicle and make sure that it is loaded so that no items can be thrown forward and hit the occupants.
This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.
Operation
Detection of vehicles
When driving, in the event of a risk of collision with the vehicle in front the system will:
- warn of the risk of collision: when the vehicle speed is between 4 mph (7 km/h) and 106 mph (170 km/h), the message “Brake” is displayed in red on the instrument panel 3 accompanied by an audible warning.
If the driver depresses the brake pedal and the system still detects a risk of collision, the brake force is increased.
- braking may be triggered: when the vehicle is moving slower than approximately 75 mph (120 km/h), if the driver does not respond to the warning and a collision becomes imminent.
If the vehicle stopped as a result of active emergency braking, the driver must keep the vehicle stationary by applying the brake pedal.
Note: if the driver uses the vehicle controls (steering wheel, pedals, etc.) the system may delay certain operations or not activate.
Special features of warnings
Depending on the speed, the warning and braking may be activated simultaneously.
Special features of stationary vehicles
Stationary vehicles are detected when your vehicle is being driven at a speed between approximately 4 mph (7 km/h) and 50 mph (80 km/h). The system is not active and does not emit a warning for stationary vehicles when you exceed approximately 50 mph (80 km/h).
In the event of emergency manoeuvre, you can stop braking at any moment by:
- tapping the accelerator pedal;
or
- turning the steering wheel as a collision avoidance manoeuvre.
Detection of pedestrians and cyclists
(depending on the vehicle)
When driving at a speed between approximately 4 mph (7 km/h) and 50 mph (80 km/h), if there is a risk of collision with a pedestrian or a cyclist, the system:
- warns you of a collision risk:
the “Brake” message is displayed in red on the instrument panel 3, accompanied by a sound signal.
If the driver presses the brake pedal and the system still detects a risk of collision, the braking force is increased if it is not sufficient to prevent the collision.
- may trigger braking:
if the driver fails to react following the alert and collision becomes imminent.
If active emergency braking has caused the vehicle to stop, the vehicle is kept stationary for a short time. Beyond this time limit, the vehicle must be held stationary by the driver keeping their foot on the brake pedal.
Note: if the driver uses the vehicle controls (steering wheel, pedals, etc.) the system may delay certain operations or not activate.
Special features of warnings
Depending on the speed, the warning and braking may be activated simultaneously.
In the event of emergency manoeuvre, you can stop braking at any moment by:
- tapping the accelerator pedal;
or
- turning the steering wheel as a collision avoidance manoeuvre.
Activating or deactivating the system
For vehicles fitted with a multimedia screen
With the vehicle stopped and the engine running, from the multimedia screen 4, select “Settings” menu, “Vehicle” tab, “Driving assistance” menu, “Active braking” then select “ON” or “OFF”.
Upon deactivation of the system, the warning light illuminates or, depending on the vehicle, the warning light illuminates on the instrument panel.
Temporarily not available
If the system detects a temporary fault the warning light illuminates, or depending on the vehicle the warning light illuminates on the instrument panel.
The possible causes are:
- the system is temporarily blinded (glare from the sun, dipped beam headlights, bad weather conditions etc.). The system will be operational again when visibility conditions are better;
- the system is temporarily interrupted (e.g. the windscreen, front or rear bumper or logo is obscured by dirt, mud, snow, condensation, etc.) In this case, park the vehicle and switch off the engine. Clean the windscreen, the front bumper or the logo. When you next start the engine, the warning light and the message go out.
If this is not the case, this may arise from another cause; contact an Approved Dealer.
Operating faults
If the function detects an operating fault, the © and warning lights or, depending on the vehicle, the warning light illuminate(s) on the instrument panel accompanied by the message “Front camera to check” or “Front radar to check” or “Check Camera/Radar”.
Consult an approved dealer.
This system is reactivated each time the ignition is switched on.
Active emergency braking
This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle. The triggering of this function may be delayed or prevented when the system detects clear signs of control of the vehicle by the driver (action on the steering wheel, pedals etc.).
The system cannot be activated:
- when the gear lever is in neutral position or the clutch pedal has been depressed for ten seconds;
- when the parking brake is activated;
- when the Electronic Stability Program (ESC) has started.
System servicing/repairs
- In the event of an impact, the radar and/or camera may become misaligned and their service may be affected. Deactivate the function and contact an Approved Dealer.
- Any work in the area where the radar and/or 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.
System disturbance
Some conditions can disturb or damage the operation of the system, such as:
- a complex environment (metal bridge, tunnel etc.);
- poor weather conditions (snow, hail, black ice etc.);
- poor visibility (night, fog etc.);
- poor contrast between the object (vehicle, pedestrian etc.) and the surrounding area (e.g. pedestrian dressed in white located in a snowy area etc.);
- being dazzled (glaring sun, lights of vehicles travelling in the opposite direction etc.);
- windscreen obscured (by dirt, ice, snow, condensation etc.);
- ...
In these conditions, the system may not react, may warn the driver or may brake inadvertently.
Limitation of the system operation
- Each time the vehicle is started, the system carries out a calibration according to the vehicle surroundings and may be inactive for a length of time between approximately two and five minutes;
- A vehicle travelling in the opposite direction will not trigger any alert or affect operation of the system;
- The radar and camera zones must be kept clean and free of any tampering in order to ensure the proper operation of the system;
- The system may not respond to small vehicles such as motorbikes as effectively as to other vehicles;
- The system may not operate optimally when the road surface is slippery (rain, snow, black ice etc.);
- To ensure correct operation, the system needs to distinguish the complete outline of the pedestrian. So the system cannot detect:
- pedestrians in the darkness or in poor lighting conditions;
- partially visible pedestrians:
- pedestrians less than approximately 80 cm tall;
- pedestrians carrying large objects;
- ...
In these conditions, the system may not react, may warn the driver or may brake inadvertently.
Deactivating the function
You must disable the function if:
- the camera area has been damaged (e.g. on the inside or outside of the windscreen);
- the front of the vehicle was damaged (impact, distortion, scratch on the radar etc.);
- the vehicle is being towed (breakdowns);
- the windscreen is cracked or distorted (do not carry out windscreen repairs in this area; have it changed by an approved dealer);
- you are not driving on a paved road.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
Halting the function
You can halt the active braking function at any time by tapping the accelerator pedal or by turning the steering wheel in a collision avoidance manoeuvre.
