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.
NOTE: On tight turns ACC performance may be limited.
