Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not be
detected.
Deceleration
The system does not decelerate in the following
situations:
▷ For pedestrians or similarly slow-moving road
users.
▷ Depending on the equipment, with red traffic
lights.
▷ For cross traffic.
▷ For oncoming traffic.
Merging vehicles
If a vehicle driving ahead of you suddenly merges
into your lane, the system may not be able to au‐
tomatically restore the selected distance. It may
not be possible to restore the selected distance
in certain situations, including if you are driving
significantly faster than vehicles driving ahead of
you, for instance when rapidly approaching a
truck. When a vehicle driving ahead of you is reli‐
ably detected, the system requests that the
driver intervene by braking and carrying out eva‐
sive maneuvers, if needed.
Cornering
When the desired speed is too high for a curve,
the speed is reduced slightly. Because curves
may not be anticipated in advance, drive into a
curve at an appropriate speed.
The system has a limited detection range. Situa‐
tions can arise in tight curves where a vehicle
driving ahead will not be detected or will be de‐
tected very late.
