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. The Cruise Control function
performs differently page 144.
Ú
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 accelerate (not to
exceed the original set speed) automatically 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 performance
of the Adaptive Cruise Control and Forward Colli-
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)

will not detect vehicles directly ahead of you.
Always be aware of the feature selected
(ACC) —
page 371.
Ú
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 operation to ensure safe
operation of the vehicle under all road condi-
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn-
ings can result in a collision and death or
serious personal injury.

WARNING!
The ACC system:

Does not react to pedestrians, oncoming

vehicles, and stationary objects (e.g., a
stopped 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 condi-
tions.
Does not always fully recognize complex

driving conditions, which can result in
wrong or missing distance warnings.
Will bring the vehicle to a complete stop

while following a target vehicle and hold
the vehicle for approximately three
minutes in the stop position. If the target
vehicle does not start moving within three
minutes the parking brake will be acti-
vated, and the ACC system will be
cancelled.
