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 if your vehicle is not equipped
with ACC
Ú
page 141.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:

If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (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 will not detect vehi -
cles directly ahead of you. Always be aware of
the feature selected
Ú
page 412.
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 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.

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 two seconds
in the stop position. At this point, there will
be an “ACC may cancel soon” chime and
warning to the driver. When ACC is
cancelled, the system will release the
brakes and the driver must take over
braking. The system can be resumed
when the target vehicle drives off by
releasing the brake and pushing the
resume button on the steering wheel.
You should switch off the ACC system:

When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).

When entering a turn lane or highway off
ramp; when driving on roads that are winding,
icy, snow-covered, slippery, or have steep
uphill or downhill slopes.

When towing a trailer up or down steep slopes.

When circumstances do not allow safe driving
at a constant speed.
