ACTIVE EMERGENCY BRAKING
Active emergency braking
The system has two types. Depending on the vehicle, one of the two systems is equipped in the vehicle.
- System A
- System B
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.
System A is composed of the radar sensor 1 and the front camera 2.
You can find that your vehicle is with the system A from the shape of the front camera area.
If your vehicle is equipped with system A, please refer to the information on “System A” in following pages.
Note: The radar sensor 1 is located behind the front bumper. It’s difficult to identify the presence of the radar.
System B is using the radar-camera sensor 3.
You can find that your vehicle is with the system B from the shape of the radar-camera sensor area.
If your vehicle is equipped with system B, please refer to the information on “System B” in following pages.
System A
Operating principle
Using the radar sensor, the system calculates the distance separating the vehicle from the one in front and alerts the driver if there is a risk of a front-end collision. The driver can then brake the vehicle to limit the damage arising from a collision.
Note: make sure that the radar sensor 1 is not obscured (by dirt, mud, snow etc. or by the fitting of accessories such as bullbars).
Operation
While driving (at speeds of between 20 and 85 mph (30 and 140 km/h)), if there is a risk of collision with the vehicle in front, the warning light 4 will be displayed on the instrument panel in red, alongside a beep.
If the driver depresses the brake pedal and the system still detects a risk of collision, the brake force is increased. If the driver fails to react following an alert of an imminent collision, the system activates the brakes.
Activating or deactivating the system
For vehicles fitted with a navigation system
On the multifunction screen 5, select the “Vehicle” menu, “Driving assistance”, and “Active braking”, and then choose “ON” or “OFF”.
You can access menu “Driving assistance” directly from button 6 .
System A (continued)
For vehicle not fitted with a navigation system
- With the vehicle at a standstill, press and hold the switch 7 OK to access the settings menu,
- repeatedly press the control 8 up or down until you reach the “Driving assistance” menu. Press the switch 7 OK;
- repeatedly press control 8up or down until you reach the “Active braking” menu, then press the switch 7 OK.
Press the switch 7 OK again to activate or deactivate the function:
= function activated
< function deactivated
The warning light is displayed on the instrument panel when the system is deactivated. This system is reactivated each time the ignition is switched on.
Conditions for non-activation of the system
The system cannot be activated:
- when the gear lever is in neutral;
- when the parking brake is activated;
- while cornering.
- For 4-wheel drive vehicles, when Electronic Stability Programme (ESC) with understeer and traction control are deactivated (please see “Electronic Stability Programme (ESC) with understeer and traction control” above). Warning light comes on.
Operating faults
When the system detects an operating fault, the warning light lights up on the instrument panel, with the message “Active braking disconnected”.
There are two possibilities:
- the system is temporarily disrupted (for example: radar obscured by dirt, mud, snow etc.). In this case, park the vehicle and switch off the engine. Clean the detection zone of the radar. 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.
Consult an approved dealer.
The system A only detects vehicles driving in the same direction of traffic. The system cannot detect motorcycles because of the difficulty in forecasting their trajectory.
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.).
System servicing/repairs
- In the event of an impact, the radar-camera or radar alignment may be changed, and its operation may consequently be affected. Deactivate the function, then consult an authorised dealer.
- Any work in the area where the radar-camera or radar are located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional.
- Fitting accessories which may block the radar is prohibited (bull bars etc.).
Only an authorised dealer is qualified to service the system.
In the event of 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.);
Risk of inadvertent braking.
Limitation of the system operation
- The system will only respond to vehicles which are moving or which have been sensed as moving.
- The radar area should be kept clean and free of any modifications in order to ensure the proper operation of the system.
- The system cannot respond to small vehicles such as motorbikes, bicycles or pedestrians as effectively as to other vehicles.
- The system may not operate properly when the road surface is slippery (rain, snow, black ice etc.).
Deactivating the function
You must disable the function if:
- the brake lights are not functioning;
- the front of the vehicle has undergone an impact or been damaged;
- the vehicle is being towed (breakdowns);
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 avoidance manoeuvre.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
System B
Operating principle
Using information from the radar-camera, the system calculates the distance which separates it from the vehicle in front and the surrounding pedestrians.
It notifies the driver if there is a risk of head-on collision. The driver can then brake the vehicle to limit the damage arising from a collision.
Note: make sure the windscreen is not obscured (dirt, mud, snow, condensation etc.).
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.
Detection of pedestrians
Operation
When driving (speed between about 4.2 mph (7 km/h) and 36 mph (60 km/h)), if there is a risk of impact with a pedestrian, the indicator 9 is displayed in red on the instrument panel and accompanied by a beep.
When the impact is imminent, the system activates the braking.
The system can apply maximum braking.
This system applies maximum braking to the vehicle
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.
System B (continued)
Detection of vehicles
Operation
When driving (speed between about 4.34 and 99.2 mph (7 and 160 km/h)), if there is a risk of collision with the vehicle in front, the system:
- warns you of a collision risk:
The indicator 4 is displayed in red on the instrument panel and accompanied by a beep.
If the driver depresses the brake pedal and the system still detects a risk of collision, the brake force is increased.
- triggers braking:
if the driver fails to react following the alert and collision becomes imminent.
You can interrupt braking at any point by:
- tapping the accelerator pedal;
or
- turning the steering wheel in an avoidance manoeuvre.
Special features
When the vehicle speed:
- is less than 27.9 mph (45 km/h) approximately, the warning and braking are activated at the same time;
- is between about 27.9 mph (45 km/h) and 48 mph (80 km/h) approximately, the warning is activated. Braking will only be triggered if the vehicle preceding you is moving. Braking is not activated for stationary vehicles;
- is between about 48 mph (80 km/h) and 99.2 mph (160 km/h), the warning and braking are only triggered if the vehicle preceding you is moving. The warning and braking are not activated for stationary vehicles;
- is above 99.2 mph (160 km/h), the system is not active.
System B (continued)
Activating or deactivating the system
For vehicles fitted with a navigation system
On the multifunction screen 5, select the “Vehicle” menu, “Driving assistance”, and “Active braking”, and then choose “ON” or “OFF”.
You can access menu “Driving assistance” directly from button 6 .
For vehicle not fitted with a navigation system
- With the vehicle at a standstill, press and hold the switch 7 OK to access the settings menu,
- repeatedly press the control 8 up or down until you reach the “Driving assistance” menu. Press the switch 7 OK;
- repeatedly press control 7 up or down until you reach the “Active braking” menu, then press the switch 7 OK.
Press the switch 8 OK again to activate or deactivate the function:
= function activated
< function deactivated
The warning light is displayed on the instrument panel when the system is deactivated. This system is reactivated each time the ignition is switched on.
System B (continued)
Conditions for non-activation of the system
The system cannot be activated:
- when the gear lever is in neutral;
- when the parking brake is activated;
- while cornering.
As a general rule, if the driver shows signs of attention (action on the steering wheel, pedals etc.), the system delays its operation or does not activate.
Temporarily not available
When the system detects a temporary unavailability, the warning light lights up on the instrument panel accompanied by the message “Active braking: sensor blind” or, depending on the vehicle, “Radar-camera: no visibility”.
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 disrupted (for example: windscreen obscured by dirt, ice, snow etc.). In this case, park the vehicle and switch off the engine. Clean the windscreen. 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
When the system detects an operating fault, the warning light lights up on the instrument panel, with the message “Active braking disconnected”.
Consult an approved dealer.

In the event of 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.).
Risk of inadvertent braking.
Limitation of the system operation
- A vehicle travelling in the opposite direction will not trigger any alert or any action on the system operation.
- The radar-camera area on the windscreen should be kept clean and free of any modifications in order to ensure the proper operation of the system.
- The system cannot respond to small vehicles such as motorbikes or bicycles as effectively as to other vehicles.
- The system may not operate properly when the road surface is slippery (rain, snow, black ice etc.).
- To ensure correct operation, System B 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 80cm tall;
- Pedestrian carrying large objects;
Deactivating the function
You must disable the function if:
- the brake lights are not functioning;
- the area of the radar-camera has been damaged (on the windscreen side or the interior rear-view mirror side);
- the vehicle is being towed (breakdowns);
- the windscreen is cracked or distorted (do not carry out repairs on this area of the windscreen; have it changed by 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 avoidance manoeuvre.
In the event of the system behaving abnormally, deactivate it and consult an authorised dealer.
