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

The system is deactivated automatically: - on switching off the ignition, - if the engine stalls, - if no manoeuvre is started within 5 minutes of selection of the type of manoeuvre, - after a prolonged stop of the vehicle during a manoeuvre, - if the road wheel anti-slip regulation (ASR) is triggered, - if the speed of the vehicle exceeds the stated limit, - when the driver interrupts movement of the steering wheel, - if the driver presses the Park Assist control, - after 4 manoeuvre cycles, - on opening the driver's door, - if one of the front wheels encounters an obstacle.
The operation indicator lamp goes off in the instrument panel and a message is displayed accompanied by an audible signal. The driver should then take back control of the vehicle's steering.
Deactivation
If the system is deactivated during a manoeuvre, the drive should reactivate it manually to repeat the measurement.
The system is switched off automatically: - when towing a trailer, - if the driver's door is opened, - if the speed of the vehicle is above 42 mph (70 km/h). To switch the system of for a prolonged period, contact a PEUGEOT dealer or a qualified workshop.
In the event of a fault with the system, this warning lamp is displayed in the instrument panel and a message appears, accompanied by an audible signal.
Operating faults
In the event of a fault with the power steering, this warning lamp comes on in the instrument panel accompanied by an alert message.
Contact a PEUGEOT dealer or a qualified workshop.
Switching off
If the lateral distance between your vehicle and the space is too great, the system may not be able to measure the space. Anything projecting beyond the envelope of the vehicle (long or wide load) is not taken into account by the Park Assist system during a manoeuvre.
In bad weather or in winter, ensure that the sensors are not covered by road dirt, ice or snow. In the event of a fault, have the system checked by a PEUGEOT dealer or a qualified workshop.
The indicator lamp for the function flashes for a few seconds. If the fault occurs during the use of the system, the indicator lamp goes off.

Safety
308_EN_CHAP06_SECURITE_ED02-2013
Dynamic stability control (DSC) and anti-slip regulation (ASR)
Activation
These systems are activated automatically each time the vehicle is started. As soon as they detect a problem of grip or trajectory, these systems act on the operation if the engine and brakes.
This is indicated by flashing of this warning lamp in the instrument panel.
The DSC system offers exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed. The correct operation of the system depends on observation of the manufacturer's recommendations regarding the wheels (tyres and rims), the braking components, the electronic components and the assembly and repair procedures used by PEUGEOT dealers. After an impact, have the system checked by a PEUGEOT dealer or a qualified workshop.
Deactivation
In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the DSC system, so that the wheels can move freely and regain grip.
Operating fault
But it is recommended that the system be reactivated as soon as possible.
 Press the button.
This warning lamp and the indicator lamp in the button come on: the DSC system no longer acts on the operation of the engine.
Reactivation
The system is reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h).
 Press the button again to reactivate it manually.
If this warning lamp comes on, accompanied by an audible signal and a message, this indicates a
fault with the system.
Contact a PEUGEOT dealer or a qualified workshop to have the system checked.
