176 STARTING AND OPERATING
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.
The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.
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 conditions, and the steepness of the hills,
ACC performance may be limited.
NOTE:
The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.
ACC Hill Example
Lane Changing
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the
illustration shown, ACC has not yet detected the
vehicle changing lanes and it may not detect the
vehicle until it's too late for the ACC system to
take action. ACC may not detect a vehicle until
it is completely in the lane. There may not be
sufficient distance to the lane-changing vehicle.
Always be attentive and ready to apply the brakes
if necessary.
