Acc Operation At Stop; Changing Modes - RAM 1500 2019 User Manual

The maximum braking applied by ACC is
limited; however, the driver can always apply
the brakes manually, if necessary.
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.
NOTE:
The "Brake!" Screen in the instrument
cluster display is a warning for the driver to
take action and does not necessarily mean
that the Forward Collision Warning system is
applying the brakes autonomously.

ACC Operation At Stop

In the event that the ACC system brings your
vehicle to a standstill while following a target
vehicle, if the target vehicle starts moving
within two seconds of your vehicle coming to
a standstill, your vehicle will resume motion
without the need for any driver action.
154
If the target vehicle does not start moving
within two seconds of your vehicle coming to
a standstill, the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the
existing Set Speed.
NOTE:
After the ACC system holds your vehicle at a
standstill for approximately 3 consecutive
minutes, the parking brake will be activated,
and the ACC system will be cancelled.
While ACC is holding your vehicle at a stand-
still, if the driver seatbelt is unbuckled or the
driver door is opened, the parking brake will
be activated, and the ACC system will be
cancelled.
WARNING!
When the ACC system is resumed, the
driver must ensure that there are no
pedestrians, vehicles or objects in the path
of the vehicle. Failure to follow these
warnings can result in a collision and
death or serious personal injury.

Changing Modes

If desired, the Adaptive Cruise Control mode
can be turned off and the system can be
operated as a Normal (Fixed Speed) Cruise
Control mode. When in the Normal (Fixed
Speed) Cruise Control mode the distance
setting feature will be disabled and the
system will maintain the speed you set.
To change between the different cruise

control modes, push the Adaptive Cruise
Control (ACC) on/off button which turns
the ACC and the Normal (Fixed Speed)
Cruise Control off.
Pushing the Normal (Fixed Speed) Cruise

Control on/off button will result in turning
on (changing to) the Normal (Fixed Speed)
Cruise Control mode.
