Peugeot 308: Electronic stability control (ESC)

The electronic stability control programme includes the following systems:

• Anti-lock braking system (ABS) and Electronic brake force distribution (EBFD).
• Emergency braking assistance (EBA).
• Post Collision Safety Brake (PCSB).
• Anti-slip regulation (ASR).
• Dynamic stability control (DSC).
• Trailer stability assist (TSA).

• Anti-lock braking system (ABS)/Electronic brake force distribution (EBFD)
• Anti-slip regulation (ASR)/ Dynamic stability control (DSC)
• Trailer stability assist (TSA)

Anti-lock braking system (ABS)/Electronic brake force distribution (EBFD)

These systems enhance the vehicle's stability and handling during braking, and enable greater control while cornering, particularly on poor or slippery road surfaces.

ABS prevents wheel locking in the event of emergency braking.

Electronic brake force distribution (EBFD) manages overall braking pressure on each individual wheel.

► When braking in an emergency, depress the pedal very firmly and maintain this pressure.

Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.

  The fixed illumination of this warning lamp signals that there is a fault with the ABS.

The vehicle retains conventional braking. Drive carefully at a moderate speed.

Have it checked by a PEUGEOT dealer or a qualified workshop.

  This warning lamp, when lit together with the STOP and ABS warning lamps, accompanied by a message and an audible signal, indicates an EBFD malfunction.

You must stop the vehicle.

Stop as soon as it is safe to do so and switch off the ignition.

Contact a PEUGEOT dealer or a qualified workshop.

When changing wheels (tyres and rims), ensure that these are approved for your vehicle.

After an impact

Have it checked by a PEUGEOT dealer or a qualified workshop.

Emergency braking assistance (EBA)

This system reduces the emergency stopping distance, by optimising the braking pressure.

It is triggered in relation to the speed at which the brake pedal is depressed. The effect of this is a reduction in the resistance of the pedal and an increase in braking efficiency.

Post Collision Safety Brake (PCSB)

If an accident is detected, the vehicle initiates automatic post collision braking. The goal of this system is to reduce the risk of further collisions if the driver does not react.

The system is not operational if the capability of the vehicle to trigger and execute the automatic post collision braking is not available, as it can occur in destructive accidents or in other specific accident scenarios.

It is possible to override the automatic braking by pressing the brake pedal or accelerator pedal.

Operating conditions

The system operates, if the following conditions are met:

• Airbags or pyrotechnic seat belt pretensioners have been deployed by the collision.
• Braking systems and electric functions remain continuously operational during and after collision.
• Driver has not depressed the brake or accelerator pedal.

Malfunction

In the event of a malfunction, one of these warning lamps will come on fixed on the instrument panel, accompanied by the Service warning lamp, the display of a message and an audible signal.

Have it checked by a PEUGEOT dealer or a qualified workshop.

Anti-slip regulation (ASR)/ Dynamic stability control (DSC)

Anti-slip regulation (or traction control) optimises traction by using engine braking and by applying the brakes on the driving wheels to avoid one or more wheels spinning. It also enhances the vehicle's directional stability.

If there is a difference between the vehicle's trajectory and the path desired by the driver, the dynamic stability control system automatically uses engine braking and the brakes on one or more wheels to return the vehicle to the desired path, within the limits of the laws of physics.

These systems are activated automatically every time the vehicle is started.

These systems are activated in the event of a problem with grip or trajectory (confirmed by this warning lamp flashing on the instrument panel).

Deactivation/Reactivation

In exceptional conditions (e.g. moving a vehicle that is bogged down in mud, stuck in snow, on loose soil), it may prove useful to deactivate the DSC/ASR systems, so that the wheels can move freely and regain grip.

Reactivate the system as soon as the level of grip permits.

The ASR system is deactivated/ reactivated in the ADAS touch screen application.

Deactivation/reactivation of the ASR system is indicated by this indicator lamp on the instrument panel coming on/going out and the display of a message.

The ASR system is automatically reactivated every time the ignition is switched off or at speeds over 31 mph (50 km/h) Reactivation is manual below 31 mph (50 km/h).

Malfunction

In the event of a malfunction, this warning lamp lights up on the instrument panel, accompanied by the display of a message and an audible signal.

Have it checked by a PEUGEOT dealer or a qualified workshop.

ASR/DSC

These systems enhance safety during normal driving, but 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 these systems activated in all conditions, and particularly in difficult conditions.

Correct operation of these systems depends on compliance with the manufacturer's recommendations relating to the wheels (tyres and rims), braking and electronic components, as well as the assembly and repair procedures provided by PEUGEOT dealers.

In order to ensure that these systems remain effective in wintry conditions, the use of snow or all-season tyres is recommended. All four wheels must be fitted with tyres approved for your vehicle.

All tyre specifications are listed on the tyre/paint label. For more information on Identification markings, refer to the corresponding section.

Trailer stability assist (TSA)

When towing, this system reduces the risk of the vehicle or trailer snaking.

Operation

The system is activated automatically when the ignition is switched on.

The electronic stability control system (ESC) must not have any faults.

The vehicle speed must be between 37 and 99 mph (60 and 160 km/h).

If the system detects that the trailer is snaking, it applies the brakes to stabilise the trailer and reduces engine power, if necessary, to slow the vehicle (indicated by the flashing of this warning lamp on the instrument panel and the brake lamps coming on).

For more information on weights and towed loads, refer to the Engine technical data and towed loads section or your vehicle's registration certificate.

To ensure safe driving with a Towing device, refer to the corresponding section.

Malfunction

If a fault occurs, this warning lamp lights up on the instrument panel, accompanied by a message and an audible signal.

To continue towing a trailer, reduce speed and drive carefully! Have it checked by a PEUGEOT dealer or a qualified workshop.

The trailer stability control system provides an extra safety feature under normal driving conditions, when following the recommendations for use of trailers and current legislation in force in your country. It must not encourage the driver to take extra risks, such as using a trailer in unsuitable conditions of operation (e.g. excessive load, exceeded nose weight, worn or under-inflated tyres, faulty braking system) or driving at excessive speed.

In certain cases, the system may not detect trailer snaking, particularly with a light trailer.

When driving on slippery or poor surfaces, the system may not be able to prevent sudden trailer snaking.
