The system is reactivated automatically at every new engine start by the driver.
Reactivation
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off, accompanied by a message.
Operating fault
In the event of a fault with the system, this warning lamp comes on continuously. Have it checked by a PEUGEOT dealer or a qualified workshop. In the event of a fault in STOP mode, the vehicle may stall.
All of the instrument panel warning lamps come on. Depending on version, an alert message may also be displayed, asking you to place the gear lever in position N and put your foot on the brake pedal. You must switch off the ignition, then start the engine again.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
This system requires a 12 V battery with a special specification and technology (reference numbers available from PEUGEOT dealers). Fitting a battery not listed by PEUGEOT introduces the risk of malfunction of the system. For charging, use a 12 V charger and do not reverse the polarity.
Maintenance
The Stop & Start system makes use of advanced technology. For any work on the system go to a qualified workshop with the skills and equipment required,
which a PEUGEOT dealer is able to provide.

Steering mounted controls
The information is grouped together in the instrument panel. 6. Cruise control pause / resume indication. 7. Cruise control mode selection indication. 8. Speed value setting.
Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance and responsibility on the part of the driver. You are advised to keep your feet near the pedals
at all times.
The cruise control is switched on manually: it requires a minimum vehicle speed of 25 mph (40 km/h).
The controls of this system are grouped together at the steering wheel. 1. Cruise control mode selection wheel. 2. Decrease value or speed setting on the fly button. 3. Increase value or speed setting on the fly
button. 4. Cruise control pause / resume button. 5. Memorised speeds display button.
Displays in the instrument panel
Switching off the ignition cancels any programmed speed value.
The cruise control is paused manually or by pressing the brake or clutch pedal or on triggering of the ESC system for safety reasons. It is possible to exceed the programmed speed temporarily by pressing the accelerator pedal. To return to the programmed speed, simply release the accelerator pedal until the programmed cruise speed is reached again.
As well as the engagement of at least third or fourth gear (depending on engine) on a manual gearbox.
For more information on the list of
memorised speeds, refer to the "Memorising speeds" section.
As well as the engagement of at least second
gear (depending on engine) on an automatic gearbox.

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).

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.

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.

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.

Park Assist
This system provides active assistance with parking, detecting a parking space then controlling the steering to park in the space. It controls the steering while the driver manages the accelerator, brakes, gears and clutch (manual gearbox). During phases of entry into and exit from a parking space, the system provides visual and audible information
to the driver in order to make the manoeuvres safe. It may be necessary to move for wards and backwards more than once.
During a manoeuvre the steering wheel turns quickly: do not hold the steering wheel, do not place your hand between the spokes of the steering wheel and take care with loose and bulky clothing, scarves, handbags... There is a risk of injury.
When Park Assist is activated, it prevents a change to STOP mode of Stop & Start. In STOP mode, activation of Park Assist restarts the engine.
The Park Assist system cannot in any circumstances replace the care and responsibility of the driver. The driver must remain in control of their vehicle ensuring that the space remains clear throughout the manoeuvre. In some circumstances, the sensors may not detect small obstacles located in their blind spots.
The driver can take control at any time by gripping the steering wheel.
The Park Assist system provides assistance for the following manoeuvres:
- entry into a parallel parking space
- exiting from a parallel parking space
- bay parking
The Park Assist system takes control of the power steering for a maximum of 4 manoeuvre cycles. The function is deactivated after these 4 cycles. If you think that your vehicle is not positioned correctly, you should then take control of the steering to carry out the manoeuvre. The Park Assist system cannot work with the engine off.
