Collision warning system* - function

1. Audio-visual warning signal in the event of a collision risk.
2. Radar sensor2
3. Camera sensor

Collision Warning with Auto Brake executes three steps in the following order:

The collision warning system and City Safety™ complement each other.

1 - Collision warning

The driver is first warned of a potentially imminent collision.

The collision warning system can detect pedestrians, cyclists or vehicles that are stationary or moving in the same direction as your car and are located in front of you.

If there is a risk of collision with a pedestrian, cyclist or a vehicle then the driver's attention is attracted with a flashing red warning signal (1) and an acoustic signal.

2 - Brake support2

If the risk of collision has increased further after the collision warning then the brake support is activated.

This means that the brake system is prepared for rapid braking by applying the brakes lightly, which may feel like a slight jolt.

If the brake pedal is depressed sufficiently quickly then full brake function is implemented.

Brake support also reinforces the driver's braking if the system considers that the braking is not sufficient to avoid a collision.

3 - Auto Brake2

The automatic brake function is activated last.

If in this situation the driver has not yet started to take evasive action and the risk of collision is imminent then the automatic braking function is deployed - this takes place irrespective of whether or not the driver brakes. Braking then takes place with full brake force in order to reduce collision speed, or with limited brake force if it is sufficient to avoid a collision. For cyclists, the warning and full brake intervention may come very late or simultaneously.
