Anti-slip regulation (ASR) and electronic stability programme (ESP)

The anti-slip regulation (also known as Traction Control) optimises traction to prevent skidding of the wheels, by acting on the brakes of the driving wheels and on the engine.

The electronic stability programme acts on the brake of one or more wheels and on the engine to keep the vehicle on the trajectory required by the driver, within the limits of the laws of physics.

Activation

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

They come into operation in the event of a grip or trajectory problem.

This is indicated by flashing of this warning lamp in the instrument panel.

Deactivation

In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground, ...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can move freely and regain grip.

Press the "ESP OFF" button, located in the middle of the dashboard.

If this warning lamp comes on in the instrument panel and the indicator lamp in the button come on, this indicates that the ASR and ESP systems are deactivated.

On vehicles fitted with the 1.6 litre THP 200 hp engine, this action also deactivates the automatic operation of hazard warning lamps.

Reactivation

These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h) (except in the case of the 1.6 litre THP 200 hp petrol engine).

Press the "ESP OFF" button again to reactivate them manually.

On vehicles fitted with the 1.6 litre THP 200 hp engine, this action also reactivates the automatic operation of hazard warning lamps.

Operating fault

If this warning lamp comes on, accompanied by an audible signal and a message in the screen, this indicates a malfunction of these systems.

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

The ESP/ASR systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed.

The correct functioning of these systems depends on observation of the manufacturer's recommendations on:

- wheels (tyres and rims),
- braking components,
- electronic components,
- repair and assembly procedures.

After an impact, have these systems checked by a PEUGEOT dealer or a qualified workshop.
