Failure to correctly detect the end of the vehicle up ahead
The adaptive cruise control radar sensor may not be able to or may incorrectly detect the end of vehicles with large projecting parts driving ahead.
Active safety - Porsche Active Safe (PAS)
The adaptive cruise control sensor is used for the Porsche Active Safe (PAS) functions.
All Porsche Active Safe (PAS) functions are active for speeds in excess of approx. 20 mph (30 km/ h).
Latent warning (visual)
If the distance when traveling behind another vehicle for a long period is too small to avoid a collision if the vehicle ahead were to brake, the latent warning (yellow icon) appears on the multifunction display to warn the driver.
Prewarning (visual and acoustic signal)
If the radar sensor detects a critical approach to a moving obstacle ahead with a high potential for collision, the visual and acoustic prewarnings are output.
The driver can then take the appropriate evasive action to avoid a collision.
