The following table describes the alerts and the messages displayed for the different driving situations.
Driving situations and associated alerts

No vehicle detected:
the system operates as a conventional cruise control.
Detection of a vehicle, at the limit of the range of the radar: the system operates as a conventional cruise control.
The display of these alerts is not sequential.

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.

Driving
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.

146
Driving
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.

Driving
Once the system has been activated and the speed conditions are met, a symbol is displayed in the instrument panel.

" SYSTEM INACTIVE: Speed unsuitable " If the speed of your vehicle is outside the operating range. Where the speed is not suitable, a message is displayed while the speed is outside limits (below 42 mph (70 km/h) or above 93 mph (150 km/h), approximately). However, when decelerating, the system is deactivated below 27 mph (45 km/h).
" System deactivated " On deactivating the function, in "DRIVING" display mode.
" SYSTEM INACTIVE: Visibility reduced " The system switches to standby automatically if the sensor does not detect the vehicle in front correctly (very difficult weather conditions, sensor out of adjustment, ...).

150
Driving
The vehicle being followed may not be detected in certain conditions such as, for example: - when turning, - when changing lane, - when the vehicle in front is out of the range of the sensor (maximum range: around 100 m).
Operating limits
In the event of a fault with the system, this warning lamp is displayed accompanied by a message.
Operating fault
Have the system checked by a PEUGEOT
dealer or a qualified workshop.
At the first use of the system after repair, a message may be displayed indicating that the system is initialising. The system is not available while this is in progress. As soon as the message disappears the system is operational again. If the message does not disappear, contact a PEUGEOT dealer or a qualified workshop.
