Cruise Control to 0 mph. In instances where the
feature capabilities are different, this is called
out. Otherwise the feature is called Adaptive
Cruise Control (ACC).
ACC may not detect vehicles driving in a different
lane or narrow vehicles, like motorcycles, driving in
front.
In particular, stay aware in the following situations:
•
when cornering, entering, and exiting bends;
•
when driving winding stretches of road;
•
when overtaking;
•
when there are vehicles driving in a different
lane;
•
when vehicles are changing lanes;
•
when vehicles are exiting the road;
•
when there are obstacles and stationary
vehicles.
ACC does not compensate for inattentive driving,
weather, or traffic conditions. ACC is only an aid. The
driver is responsible for maintaining a safe distance
from the vehicle in front, maintaining a safe vehicle
speed, braking, and remaining in a lane.
If ACC does not detect a vehicle driving in front, the
system accelerates to the set speed.

When a vehicle is detected in front, the driver display
shows a generic image of the detected vehicle, the
detected vehicle's speed, and the distance to it. See

Adaptive Cruise Control Functions and
Activation Conditions
ACC controls the speed of the equipped vehicle to
maintain a safe distance from a vehicle detected in
front.
If ACC detects a vehicle in front driving at a slower
speed, the engine is defueled, the engine brakes are
activated, and the service brakes are applied,
slowing the vehicle to maintain the set following
distance. The standard factory-set following distance
is 3.6 seconds; for vehicles configured with
adjustable headway, this can be adjusted under the
'Cruise Control' menu under 'Vehicle Settings.'
In vehicles equipped with a DT12 transmission, ACC
to 0mph allows the vehicle to operate in cruise all the
way down to 0 mph (0 km/h). As traffic in front of the
vehicle slows and eventually stops, the vehicle
adjusts with the traffic.
If the vehicle ahead causes the truck to be stopped
for two seconds or less, ACC to 0 mph resumes
when the vehicle ahead moves. If the vehicle ahead
is stopped for more than two seconds, the driver—
after carefully checking surrounding traffic—must
press the resume button or tap the accelerator pedal
to move forward.
