Active cruise control
This systems allows the vehicle's speed to be maintained at a value set by the driver. In addition it allows (when circumstances permit) an inter-vehicle time that you have selected (around 2 seconds by default and at each activation of the system) to be maintained.
Principles of operation
Using a radar with a range of about 100 metres, located at the front of the vehicle, this system detects a vehicle running in front of your vehicle. It automatically adapts the speed of your
vehicle to that of the vehicle in front. If the vehicle in front is running more slowly, the system progressively reduces the speed of your vehicle using just engine braking (as if the driver had pressed the " - " button). If your vehicle is too close to, or approaching too quickly the vehicle in front, the cruise control is automatically deactivated. The driver is then alerted by an audible signal, accompanied by a message. If the vehicle in front accelerates or changes lane, the active cruise control progressively accelerates your vehicle to return to the programmed speed. If the driver operates a direction indicator to overtake a slower vehicle, the active cruise control allows your vehicle to temporarily approach the vehicle in front to assist the overtaking manoeuvre, though never exceeding
the programmed speed.
The active cruise control operates by day and at night, in fog or moderate rainfall.
The system does not act on the braking system, but works only with engine braking. The regulation range is limited: there will no longer be any adjustment of speed if the difference between the programmed speed setting and the speed of the vehicle in front becomes too high.
The activation of this system deactivates the display of inter-vehicle time.
If the difference between the programmed speed setting and the speed of the vehicle in front is too great, the speed cannot be adjusted:
the cruise control is automatically deactivated.

The active cruise control is switched on manually, it requires that the speed of the vehicle be between 25 mph (40 km/h) and 90 mph (150 km/h).
General points
The active cruise control can be pausedmanually with the control, or automatically: - by pressing the brake or clutch pedal, - in the event of operation of the ESP, for safety reasons, - in the event of an action of the electric parking brake control, - when an inter-vehicle time threshold is reached (calculated according to the relative speeds of your vehicle and the vehicle in front and the inter-vehicle time setting chosen), - when the distance between your vehicle and the one in front becomes to small, - when the speed of the vehicle in front is to low, - when the speed of your vehicle becomes too low.
The active cruise control cannot in any circumstances replace the observation of speed limits, nor the the vigilance and responsibility of the driver. It is recommended that you always keep your feet close to the pedals.
Switching off the ignition cancels any programmed value, and the inter-vehicle time is reset to 2 seconds.
As well as the engagement of at least third or fourth gear (depending on engine) on a manual gearbox.
As well as the engagement of at least second gear (depending on engine) on an automatic gearbox.
If the cruise speed setting is above 90 mph (150 km/h), the active cruise control switches to normal cruise control mode (without automatic adjustment of the safety inter-vehicle distance).

Modification of the cruise
control speed and/or the
inter-vehicle time
Modification of the cruise
control speed only
Buttons 2 (SET+) and 3 (SET-)
If the cruise control is on, you can modify the speed:  by successive short presses, to modify by steps of + or - 1 mph (km/h),  by a maintained press, to modify in steps of + or - 5 mph (km/h).
Press button 5 , the six memorised speeds and the inter-vehicle time setting are displayed in the touch screen.  Choose a speed setting: it is displayed in the instrument panel,  press or the " + " or " - " button to choose a new inter-vehicle time setting between 2.5 seconds and 1 second. The selection screen closes after a few moments. The modifications are then accepted.
In the event of the presence of a vehicle detected by the radar, if the speed selected is much higher than
the speed of that vehicle, the system is not activated and the alert message "Activation not possible, conditions unsuitable" is displayed until driving conditions are safe to allow activation of the system.
Exceeding the programmed
speed
As a precaution, it is recommended that you select a cruise speed setting close to the current speed of your vehicle.
It is possible to exceed the programmed speed temporarily by depressing the accelerator pedal. Simply release the accelerator pedal to return to the programmed speed. If the programmed speed is unintentionally exceeded, descending a steep hill for example, the speed setting in the instrument panel flashes as a warning.

When the active cruise control is automatically paused, it can only be reactivated when safe conditions are restored. The message "Activation not possible, conditions unsuitable" is displayed while reactivation is not possible. When the conditions allow, it is recommended that the function be reactivated by pressing button 2 (SET+) or 3 (SET-), which will make the current speed of your vehicle the new cruise speed setting, rather than by pressing button 4 (on/pause) which reactivates the cruise control using the old cruise speed setting, which may be very different from the current speed of your vehicle.

"SPEED ADJUSTED" Detection of a vehicle that is too close or running at a speed lower than your vehicle's cruise speed setting. The system uses engine braking to slow your vehicle (within a limit of 20 mph (30 km/h)) and then hold it at the speed of the vehicle in front so as to observe the programmed inter-vehicle time. When automatically slowing down behind a vehicle, your true speed may be higher than the "adjusted speed" displayed.
"Cruise control paused". If the system exceeds the limit of speed adjustment possible by the system and in the absence of any reaction by the driver (operation of the direction indicator, change of lane, reduction of the speed of the vehicle), the system is automatically paused. The display of the deactivation message is accompanied by an audible signal.

The speed regulation range is limited to a maximum difference of 20 mph (30 km/h) between the speed setting and the speed of the vehicle in front. Above this, the system goes into pause if the
safe distance becomes too low. The active cruise control uses only engine braking to slow the vehicle. Consequently the vehicle looses speed slowly, as when releasing the accelerator pedal. The system is paused automatically: - if the vehicle in front slows down to much or too suddenly, and the driver does not brake, - if a vehicle comes between your vehicle and the vehicle in front, - if the system does not slow the vehicle enough to continue to maintain a safe distance, for example when descending a steep hill.
Limits of operation
As the radar's field of view is quite narrow, it is possible that the system may not detect:
The cruise control does not take account of: - stationary vehicles, - vehicles driving in the opposite direction.
- vehicles of reduced width, such as motorcycles, for example,
- vehicles not running in the middle of the lane,
- vehicles entering a corner, - vehicles changing lane at the last moment.

In the event of a fault with the active cruise control, you are alerted by an audible signal and display of the message message "Driving aid functions fault". Have the system checked by a PEUGEOT dealer or a qualified workshop.
When the cruise control is working, take care if making a maintained press on one of the cruise control programmed speed modification buttons: this can lead to a very quick change in the speed of your vehicle. Do not use the active cruise control on slippery sur faces or in heavy traffic. When descending a steep hill, the cruise control may not be able to prevent the vehicle from exceeding the programmed speed. When ascending a steep hill or when towing, it might not be possible to attain or maintain the programmed speed.
Operating fault
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 snow, mud, ...
The use of mats not approved by PEUGEOT may inter fere with the operation of the active cruise control. To avoid any risk of jamming the pedals: - ensure that mats are positioned correctly, - never fit one mat on top of another.

Display of inter-vehicle time
Using a radar located at the front of the vehicle, this system helps the driver maintain a safe distance between their vehicle and the one in front, by displaying the inter-vehicle time in the instrument panel. It is the time interval, expressed in seconds, that separates two vehicles in line. The recommended safe value is about 2 seconds: refer to the legislation or highway code in force in your country.
Activation / deactivation
 Press this button, the indicator lamp comes on.
The measurement is displayed for information only: the system takes no action on the vehicle. This system does not in any circumstances replace the vigilance and responsibility of the driver who must remain in control of their vehicle at all times. The system is not designed for urban use nor during more dynamic driving (bends, acceleration, harsh braking…)
but rather when driving at stable speed.
The system is active in a speed range between 42 and 93 mph (70 and 150 km/h). Stationary vehicles and certain other road users (such as bicycles for example) are not detected. The system displays inter-vehicle time values of between 3 seconds and 0.5 of a second. Below 0.5 of a second, the value displayed is maintained at this level, even if the true inter-vehicle time is less. Activation of the active cruise control automatically deactivates the system.
The state of the system is memorised when the ignition is switched off.
Activation of the system is done in the " Driving assistance " menu, with the engine running.
