CRUISE CONTROL SYSTEMS
Your vehicle is equipped with the Adaptive
Cruise Control (ACC) system which will adjust
the vehicle speed up to the preset speed to
maintain a distance with the vehicle ahead.
NOTE:
In vehicles NOT equipped with the Active Driving
Assist System (ADAS):
Fixed Speed Cruise Control can be used
when ACC is not enabled, and functions as
normal cruise control.
Fixed Speed Cruise Control will not detect
vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate
at a time. For example, if Fixed Speed Cruise
Control is enabled, Adaptive Cruise Control
will be unavailable, and vice versa.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the
driving convenience provided by Cruise Control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions.
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 a radar sensor and a
forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceleration
(not to exceed the original set speed) auto-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
Any chassis/suspension or tire size modifica-
tions to the vehicle will affect the perfor-
mance of the Adaptive Cruise Control and
Forward Collision Warning system.
In vehicles NOT equipped with the Active
Driving Assist system, Fixed Speed Cruise
Control alone will not detect vehicles directly
ahead of you. Always be aware of the feature
selected Ú page 395.
WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driver 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 opera-
tion 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 a collision and death or serious personal
injury.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stationary vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
