154 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes an infrared
sensor designed to detect a vehicle directly ahead in your
path.
NOTE:
• If the sensor does not detect a vehicle directly ahead of
you, ACC will function in the same way as a standard
cruise control system. For additional information, refer
to "Electronic Speed Control" in this section.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically so
that your vehicle maintains a preset following dis-
tance.
WARNING!
• Adaptive Cruise Control (ACC) is a convenience system. It is not
a substitute for active driving involvement. It is always the
driver's responsibility to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe operation of the
vehicle under all road conditions. Your complete attention is
always required while driving to maintain safe control of your
vehicle. Failure to follow these warnings can result in an accident
or serious personal injury.
• The ACC system:
− Does not react to pedestrians, oncoming vehicles, and stationary
objects (i.e., a stopped vehicle in a traffic jam or a disabled
vehicle).
− Does not predict the lane curvature or the movement of preceding
vehicles and will not compensate for such changes.
− Cannot take street, traffic, and weather conditions into account,
and may be limited upon adverse sight distance conditions.
− Does not always fully recognize complex driving conditions,
which can result in wrong or missing distance warnings.
− May not detect a vehicle ahead when strong light (for example,
sunrise or sunset) is directly shining on the front of the vehicle.
− Can only apply a maximum of 25% of the vehicle's braking
capability, and will not bring the vehicle to a complete stop.
