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.
Turn Or Bend Example
Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in your
lane. Depending on the speed, vehicle load, traffic condi-
tions, and the steepness of the hills, ACC performance may
be limited.
