RAM Commercial Chassis Cab 3500 2019, Owner'S Manual

Page: 299 / 607

STARTING AND OPERATING 297
Distance Setting 1 Bar (Short)
The system automatically defaults to the longest distance
setting. To decrease the distance setting, push the Distance
Button and release. Each time the button is pushed, the
distance setting decreases by one bar. Once the shortest
setting is reached, if the button is pushed again it will reset
to the default setting (longest).
If there is no vehicle ahead, the vehicle will maintain the set
speed. If a slower moving vehicle is detected in the same
lane, the instrument cluster displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle speed auto -
matically to maintain the distance setting, regardless of the
set speed.
The vehicle will then maintain the set distance until:
• The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of the
sensor.
• The distance setting is changed.
• The system disengages. (Refer to the information on ACC
Activation).
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if neces -
sary.
NOTE:
The brake lights will illuminate whenever the ACC system
applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
