Driving and Driving Safety
C – Driving into and out of corners
When driving into and out of corners, vehicles will
not be detected or will be detected too early,
or adaptive cruise control will react to vehicles in
adjacent lanes.
D – Stationary vehicles
A stationary vehicle that appears suddenly in the
detection field of the radar sensor, e.g. after
a vehicle in front changes lanes, will not be
detected by adaptive cruise control.
Active Safety – Porsche “Active Safe”
The adaptive cruise control sensor is used for
the Porsche “Active Safe” functions.
These include:
–
Brake system prefilling
Prefilling of the brake system if the radar
sensor detects that the vehicle is coming
critically close to a moving obstacle in order
to bridge the air gaps and improve braking
response.
–
Brake Assist Plus
Reduction of the activation threshold of the
Brake Assist function if the sensor detects that
the vehicle is coming critically close to
a moving obstacle.
The activation threshold of the Brake Assist
function is reduced in three stages, depending
on how critical the danger situation is.
Information
– All Porsche “Active Safe” functions are active
for speeds of more than 20 mph (30 km/h).
Latent warning (visual)
If the vehicle is driving too close to the vehicle in
front for a long time, to avoid a collision if the
vehicle in front brakes, a latent warning appears
on the multi-purpose display to warn the driver.
f
Stay further back from the vehicle in front if
necessary.
