Electronic Stability Control (ESC) 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).
Electronic stability control (ESC)
Definitions
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.
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-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.

Operation
Anti-lock braking system (ABS) and electronic brake force distribution (EBFD)
In emergency braking, press very firmly without releasing the pressure.
When changing wheels (tyres and rims), make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.
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
Intelligent traction control
system
The use of snow tyres is strongly recommended on sur faces offering low levels of adhesion.
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.
Depending on version, your vehicle has a system to help driving on snow: intelligent traction control. This system detects situations of difficult sur face adhesion that could make it difficult to move off or make progress on deep fresh snow or compacted snow. In these situations, the intelligent traction control limits the amount of wheel slip to provide the best traction and trajectory control for your vehicle. In extremely severe conditions (deep snow, mud, ...), when it proves impossible to move off, it may be useful to temporarily deactivate the ESP/ASR systems to allow the wheels to spin freely and so allow movement of the vehicle.

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.

Seat belts
Front seat belts Rear seat belts
The rear seats are each fitted with a seat belt, three-point anchorages with inertia reel and force limiter (except for the centre rear seat).
Fastening
 Pull the strap, then insert the tongue in the buckle.  Check that the seat belt is fastened correctly by pulling the strap.
Unfastening
 Press the red button on the buckle.  Guide the seat belt as it reels in.
The front seat belts are fitted with a pretensioning and force limiting system. This system improves safety in the front seats in the event of a front or side impact. Depending on the severity of the impact, the pretensioning system instantly tightens the seat belts against the body of the occupants. The pretensioning seat belts are active when the ignition is on. The force limiter reduces the pressure of the seat belt on the chest of the occupant, so improving their protection.

The driver must ensure that passengers use the seat belts correctly and that they are all restrained securely before setting off. Wherever you are seated in the vehicle, always fasten your seat belt, even for short journeys. Do not interchange the seat belt buckles as they will not fulfil their role fully. The seat belts are fitted with an inertia reel permitting automatic adjustment of the length of the strap to your size. The seat belt is stowed automatically when not in use. Before and after use, ensure that the seat belt is reeled in correctly. The lower part of the strap must be positioned as low as possible on the pelvis. The upper part must be positioned in the hollow of the shoulder. The inertia reels are fitted with an automatic locking device which comes into operation in the event of a collision, emergency braking or if the vehicle rolls over. You can release the device by pulling firmly on the strap and releasing it so that it reels in slightly.
Recommendations for children
Use a suitable child seat if the passenger is less than 12 years old or shorter than one and a half metres. Never use the same seat belt to secure more than one person. Never allow a child to travel on your lap.
In order to be effective, a seat belt must: - be tightened as close to the body as possible, - be pulled in front of you with a smooth movement, checking that it does not twist, - be used to restrain only one person, - not bear any trace of cuts or fraying, - not be converted or modified to avoid affecting its performance. In accordance with current safety regulations, for all repairs on your vehicle, go to a qualified workshop with the skills and equipment needed, which a PEUGEOT dealer is able to provide. Have your seat belts checked regularly by a PEUGEOT dealer or a qualified workshop, particularly if the straps show signs of damage. Clean the seat belt straps with soapy water or a textile cleaning product, sold by PEUGEOT dealers. After folding or moving a seat or rear bench seat, ensure that the seat belt is positioned and reeled in correctly.
In the event of an impact
Depending on the nature and seriousness of the impact , the pretensioning device may be deployed before and independently of the airbags. Deployment of the pretensioners is accompanied by a slight discharge of harmless smoke and a noise, due to the activation of the pyrotechnic cartridge incorporated in the system. In all cases, the airbag warning lamp comes on. Following an impact, have the seat belts system checked, and if necessary replaced,
by a PEUGEOT dealer or a qualified
workshop.

Airbags
System designed to maximise the safety of the occupants (with the exception of the rear centre passenger) in the event of violent collisions. The airbags supplement the action of the force-limiting seat belts (with the exception of the centre rear passenger). If a collision occurs, the electronic detectors record and analyse the front and side impacts sustained in the impact detection zones: - in the case of a serious impact, the airbags are deployed instantly and contribute towards better protection of the occupants of the vehicle (with the exception of the rear centre passenger); immediately after the impact, the airbags deflate rapidly so that they do not hinder visibility or the exit of the occupants, - in the case of a minor or rear impact or in certain roll-over conditions, the airbags will not be deployed; the seat belt alone contributes towards ensuring your protection in these situations.
The airbags do not operate when the ignition is switched off. This equipment will only deploy once. If a second impact occurs (during the same or a subsequent accident), the airbag will not be deployed again.
Deployment of the airbag(s) is accompanied by a slight emission of smoke and a noise, due to the activation of the pyrotechnic cartridge incorporated in the system. This smoke is not harmful, but sensitive individuals may experience slight irritation. The noise of the detonation may result in a slight loss of hearing for a short time.
Impact detection zones
A. Front impact zone. B. Side impact zone.

To assure the safety of your child, the passenger's front airbag must be deactivated when you install a "rear facing" child seat on the front passenger seat. Otherwise, the child would risk being seriously injured or killed if the airbag were deployed.
Reactivating the passenger's front airbag
When you remove the child seat, with the ignition off , turn the switch to the the ignition off , turn the switch to the the ignition off"ON" position to reactivate the airbag and so assure the safety of your front passenger in the event of an impact.
Front airbags
Deployment
The airbags are deployed, except the passenger's front airbag if it is deactivated, in the event of a serious front impact to all or part of the front impact zone A , in the longitudinal centreline of the vehicle on a horizontal plane and directed from the front to the rear of the vehicle. The front airbag inflates between the thorax and head of the front occupant of the vehicle and the steering wheel, driver's side, and the dashboard, passenger's side to cushion their for ward movement.
System which protects the driver and front passenger in the event of a serious front impact in order to limit the risk of injury to the head and thorax. The driver's airbag is fitted in the centre of the steering wheel; the front passenger's airbag is fitted in the dashboard above the glove box.
When the ignition is switched on, this warning lamp comes on in the seat belt display screen for approximately one minute to signal that the front airbag is activated.
