Emergency collision alert system and emergency collision braking system
Emergency collision alert
The emergency collision alert system can be
activated or deactivated by the driver. From the secondary page of the " Driving assistance " menu:  Select the " Vehicle settings " menu.  Check the " Collision risk alert and auto braking " line and confirm.
This system has been designed to improve driving safety. The driver must constantly monitor the traffic conditions, to assess the distance and relative speed of other vehicles. The collision risk alert system can never replace the vigilance and responsibility of the driver.
This system operates from 20 mph (30 km/h), only when other vehicles are running in the same direction as your vehicle; the system does not detect stationary objects. A radar is fitted at the front of the vehicle.
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.

From the secondary page of the " Driving assistance " menu:  Select the " Vehicle settings " menu.  Check the " Collision risk alert and auto braking " line.
The alert thresholds determine how you want to be alerted to the presence of a vehicle running in front of you. You can choose from three thresholds: - 1: "Distant", to be given an early alert (cautious driving). - 2: "Normal". - 3: "Close", to be given a later alert (sporty driving).
Setting the thresholds for the alert
 Press on the magnifying glass.
 Modify the alert threshold and press on " Finish " to memorise the threshold and leave the menu.  Press on " Confirm " to save the change.

The change from one level of alert to the next takes place if the driving conditions do not change (speed unchanged, no change of lane...)
If the speed of your vehicle is too high when approaching another vehicle, the first level of alert may not be displayed: the level 2 alert may be displayed di r e c t l y. On the other hand, the level 1 alert is never displayed with the "close" triggering threshold 3. Severe weather conditions (very heavy rain, accumulations of snow in front of the radar) may inter fere with the operation of the system, resulting in the display of this message " SYSTEM INACTIVE: Reduced visibility ". The system will remain unavailable until the message disappears.
The emergency collision alert system does not replace the vigilance and responsibility of the driver.
Alerts
According to the collision risk detected by the system and the alert threshold chosen, different levels of alert can be given.
Level 1 : visual alert only (orange) indicating that the vehicle in front is very close. The message " Vehicle close " is displayed.
Level 2 : visual (red) and audible alerts indicating that a collision is imminent. The message " Brake! " is displayed.
This level of alert is based on the inter-vehicle time between your vehicle and the one in front.
This level of alert is based on a time before collision. It takes account of the vehicle dynamics, the speed of your vehicle and the speed of the vehicle in front, the driving conditions, the situation with your vehicle (cornering, pedals pressed, etc.) to trigger the alert at the right moment.

Emergency automatic braking is a system that aims to reduce the speed of a frontal collision if the driver does not take action, using radar type detection and acting on the vehicle's braking system.
Emergency automatic
braking system
This warning lamp flashes when your vehicle "starts" to brake but will not in any circumstance completely stop the vehicle.
You should continue to press firmly on the brake pedal until the vehicle comes to a complete stop.
Conditions for activation
Emergency automatic braking only operates in the following conditions: ● e n g i n e r u n n i n g ● no fault in the electronic stability system, ● speed at least 12 mph (20 km/h), ● engine speed sufficiently high, ● not in a tight corner.
 Press the magnifying glass.
 Modify the alert threshold and check the " Auto braking " line.  Press on " Finish " to memorise the threshold and leave the menu.  Press on " Confirm " to save the change.
When the emergency collision braking system is not activated, this warning lamp is
on fixed.
From the secondary page of the " Driving assistance " menu:  Select the " Vehicle settings " menu.  Check the " Collision risk alert and auto braking " line.

Operating fault
In the event of a fault, you are alerted by the display of the Service warning lamp, accompanied by a message. Consult a PEUGEOT dealer or a
qualified workshop.
The operation of the radar, located in the front bumper, may be disturbed in certain weather conditions, for example: with accumulations of snow, ice, mud, ... Clean the front bumper, removing the

Blind spot sensors
Operation
A warning lamp appears in the door mirror on the side in question: - immediately, when being overtaken, - after a delay of about one second, when overtaking a vehicle slowly.
This driving assistance system warns the driver of the presence of another vehicle in the blind spot angle of their vehicle (areas masked from the driver's field of vision), as soon as this presents a potential danger.
This indicator lamp comes on in the instrument panel. Sensors fitted in the front and rear bumpers monitor the blind spots.
This system is designed to improve safety when driving and is in no circumstances a substitute for the use of the interior rear view mirror and door mirrors. It is the driver's responsibility to constantly check the traffic, to asses the distances and relative speeds of other vehicles and to predict their movements before deciding whether to change lane. The blind spot sensor system can never replace the vigilance and responsibility of the driver.
Activation of the system is done in the " Driving assistance " menu of the touch screen.
 Press this button to activate the function; the associated indicator lamp comes on.

The alert is given by a warning lamp which comes on in the door mirror on the side in question as soon as a vehicle - car, lorry, bicycle - is detected and the following conditions are fulfilled: - all the vehicles must be moving in the same direction, - the speed of your vehicle is between 7 and 87 mph (12 and 140 km/h), - the difference in speed between your vehicle and the other vehicles must be less than 6 mph (10 km/h), - the traffic must be flowing normally, - in the case of an overtaking manoeuvre, if this is prolonged and the vehicle being overtaken remains in the blind spot, - you are driving on a straight or slightly curved road, - your vehicle is not pulling a trailer, a caravan...
No alert will be given in the following situations: - in the presence of stationary objects (parked vehicles, barriers, street lamps, road signs...), - with vehicles moving in the opposite direction, - driving on a sinuous road or a sharp c o r n e r,
- when overtaking (or being overtaken by) a very long vehicle (lorry, coach...) which is at the same time detected at the rear in the blind spot angle and present in the driver's for ward field of vision, - in very heavy traffic: vehicles detected in front and behind are confused with a lorry or a stationary object, - when overtaking quickly.

 To deactivate the system, press this button again; its indicator lamp goes off as well as the associated indicator in the instrument panel.
In the event of a fault, the warning lamp flashes then goes off.
Operating fault
Have it checked by a PEUGEOT dealer or a qualified workshop.
The system is automatically deactivated when towing with a towbar approved by P E U G E O T.
The system may suffer temporary interference in certain weather conditions (rain, hail...). In particular, driving on a wet sur face or moving from a dry area to a wet area can cause false alerts (for example, the presence of a fog of water droplets in the blind spot angle is interpreted as a vehicle). In bad or wintry weather, ensure that the sensors are not covered by mud, ice or snow. Take care not to cover the warning zone in the door mirrors or the detection zones on the front and rear bumpers with adhesive labels or other objects; they may hamper the correct operation of the system.
The state of the system remains in memory on switching off the ignition.
High pressure jet wash When washing your vehicle, direct the lance at least 30 cm away from the sensors.
