Operating principle

Ultrasonic detectors, installed in the rear bumper (depending on the vehicle), measure the distance between the vehicle and an obstacle whilst reversing.

This measurement is indicated by beeps which become more frequent the closer you come to the obstacle, until they become a continuous beep when the vehicle is approximately 30 centimetres from the obstacle.

The cruise control function helps you to maintain your driving speed at a speed that you choose, called the cruising speed.

This cruising speed may be set at any speed above 20 mph (30 km/h).

This lane departure warning system notifies the driver when they accidentally cross a continuous or broken line.

This function uses a camera attached to the windscreen, behind the rear-view mirror.

Depending on the vehicle, this is composed of:

- anti-lock braking system (ABS);

- electronic stability control (ESC) with understeer control, traction control and assistance with side winds;

- emergency brake assist;

- hill start assistance.
