Electronic stability programme (ESC)
Definitions
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to limit wheel slip by acting on the brakes of the driving wheels and on the engine. It also improves the directional stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed by the vehicle and that required by the driver, the DSC monitors each wheel and automatically acts on the brake of one or more wheels and on the engine to return the vehicle to the required path, within the limits of the laws of physics.
Emergency braking assistance
In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping distance. It is triggered according to the speed at which the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an increase in the effectiveness of the braking.
Anti-lock braking system (ABS) and electronic brake force distribution (EBFD)
This system improves the stability and manoeuvrability of your vehicle when braking and provides improved control in corners, in particular on poor or slippery road sur faces. The ABS prevents wheel lock in the event of emergency braking. The electronic brake force distribution system manages the braking pressure wheel by wheel.
Electronic Stability Programme (ESC: Electronic Stability Control) incorporating the following systems: - the anti-lock braking system (ABS) and the electronic brake force distribution (EBFD), - the emergency braking assistance, - the anti-slip regulation (ASR) or traction control, - the dynamic stability control (DSC).

Dynamic stability control (DSC) and anti-slip regulation (ASR)
This is indicated by flashing of this warning lamp in the instrument panel.
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.
Operation
When this warning lamp comes on, accompanied by an audible signal and a message, it indicates that there is a fault with the ABS, which could cause loss of control of the vehicle when braking.
When this warning lamp comes on, coupled with the STOP warning lamp, accompanied by an audible signal and a message, it indicates that there is a fault with the electronic brake force distribution (EBFD), which could cause loss of control of the vehicle when braking.
You must stop as soon as it is safe to do so. In both cases, contact a PEUGEOT dealer or a qualified workshop.
Anti-lock braking system (ABS) and electronic brake force distribution (EBFD)
In emergency braking, press very firmly without releasing the pressure.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.
When changing wheels (tyres and rims), make sure that these are approved for your vehicle.

Safety

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 and ASR, so that the wheels can turn freely and regain grip.
 Press this button. The indicator lamp in the button comes on.
The DSC and ASR systems no longer act on the operation of the engine and on the brakes in the event of a involuntary change of trajectory.
Reactivation
The systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h).
Operating fault
Illumination of this warning lamp and the lamp in the deactivation button, accompanied by an audible signal and a message, indicate a fault with the system. Contact a PEUGEOT dealer or a qualified workshop to have the system checked.
Below 30 mph (50 km/h), you can reactivate them manually:  Press this button again.
DSC/ASR
The DSC and ASR systems offer increased safety in normal driving, but they should not encourage the driver to take extra risks or drive at high speed. It is in conditions of reduced grip (rain, snow, ice) that the risk of loss of grip increases. It is therefore important for your safety to keep the DSC and ASR systems activated in all conditions, and particularly in difficult conditions. The correct operation of these systems depends on observation of the manufacturer's recommendations regarding as much the wheels (tyres and rims), braking and electronic components as the assembly and repair procedures used by PEUGEOT dealers. To benefit in full from the effectiveness of the DSC and ASR systems in wintry conditions, the vehicle must be fitted with four snow tyres, allowing the the vehicle to retain neutral behaviour on the road.
Reactivate the systems as soon as the level of grip permits.
After an impact, have these systems checked by a PEUGEOT dealer or a qualified workshop.

Grip control
Standard mode (ESC)
 Place the dial in this position.
Snow mode
Special patented traction control system which improves traction on snow, mud and sand. Associated with all-season M+S (Mud and Snow) tyres, this system offers a compromise between safety, grip and traction. This system, the operation of which has been optimised for each situation, allows you to manoeuvre in most conditions of poor grip
(encountered during touring use).
Mode calibrated for a low level of wheel spin, based on the different levels of grip normally encountered on the road.
Mode which adapts its strategy to the conditions of grip encountered for each of the two front wheels on moving off.
 Place the dial in this position.
The accelerator pedal should be pressed sufficiently to allow the system to use the power of the engine. Operation at high engine speeds is completely normal.
Every time the ignition is switched off, the system automatically resets to this mode.
A five-position selector allows you to choose the setting best suited to the driving conditions encountered. A message appears confirming the mode selected.

Emergency braking
In the event of a failure of the main service brake or in an exceptional situation (e.g. driver taken ill, under instruction, etc) a continuous pull on the control lever on the control lever on the control leverA will stop the vehicle . The dynamic stability control (DSC) provides stability during emergency braking. If there is a fault with the emergency braking, one of the following messages will be displayed: - "Parking brake faulty". - "Parking brake control faulty".
If a failure of the DSC system is signalled by the illumination of this warning lamp, then braking stability is not guaranteed.
The emergency braking must only be used in exceptional circumstances.
Particular situations
In certain situations (e.g. starting the engine), the parking brake can automatically alter its force. This is normal operation. To advance your vehicle a few centimetres without starting the engine, but with the ignition on, press on the brake pedal and release the parking brake by pulling then releasing control lever A . The full release of the parking brake is confirmed by the warning lamp in the control lever A and the warning lamp in the instrument panel going off and the display of the message "Handbrake off ". If a parking brake fault occurs while applied or if the battery runs flat, an emergency release is always possible.
Before leaving the vehicle, check that parking brake warning lamp in the instrument panel is on, not flashing.
In this event, stability must be assured by the driver by repeating alternate "pull release" actions on control lever A .

Hill start assist
Operation
On an ascending slope, with the vehicle stationary, the vehicle is held for a momentarily when you release the brake pedal: - provided you are in first gear or neutral on a manual gearbox, - provided you are in position A or A or AM on an electronic gearbox, - provided you are in position D or M on an automatic gearbox.
On a descending slope, with the vehicle stationary and reverse gear engaged, the vehicle is held momentarily when you release the brake pedal.
Operating fault
If a fault in the system occurs, these warning lamps come on. Contact a PEUGEOT dealer or a qualified workshop to have the system checked.
System which keeps your vehicle immobilised temporarily (approximately 2 seconds) when starting on a gradient, the time it takes to move your foot from the brake pedal to the accelerator pedal. This system only operates when: - the vehicle is completely stationary, with your foot on the brake pedal, - in particular conditions on a slope, - with the driver’s door closed. The hill start assist system cannot be deactivated.
Do not exit the vehicle while it is being held in the hill start assist phase. If you need to exit the vehicle with the engine running, apply the parking brake manually then ensure that the parking brake warning lamp (and the warning lamp P in the lever of the electric parking brake) are on fixed (not flashing).
