Offset Driving
ACC may not detect a vehicle in the same lane that is offset
from your direct line of travel, or a vehicle merging in from
a side lane. There may not be sufficient distance to the
vehicle ahead. The offset vehicle may move in and out of
the line of travel, which can cause your vehicle to brake or
accelerate unexpectedly.

Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
stability reasons, with no target vehicle detected. Once
the vehicle is out of the curve the system will resume
your original Set Speed. This is a part of normal ACC
system functionality.
