Acute warning (visual, acoustic and braking jolt)

Fig. 11: Prewarning

If the driver does not react to the prewarning by braking, this is quickly followed by an acute warning, which involves a braking jolt in addition to the visual and acoustic warning.

A braking jolt is initiated by means of a very rapid build-up of brake pressure in order to draw the driver’s attention to the traffic situation.

In this dangerous situation, the driver can still prevent a collision by taking the appropriate action.

Insufficient distance
Risk of collision with the vehicle in front.

  • Brake immediately.

The situations described below lead to the assumption that the driver is driving carefully and the prewarning and acute warning functions are disabled:

  1. The driver is driving around tight bends
  2. The driver is braking
  3. If the driver accelerates sharply, this action is interpreted as an active driving request (e.g. indicating the driver’s intention to overtake).

Switching Porsche Active Safe (PAS) warnings on/off
The latent warning and prewarning functions are off as standard, whereas the acute warning function is active. To switch on the latent warning and prewarning on the multifunction display:
