Jeep 2014 Cherokee - Owner Manual - Manual (Page 204)

The maximum braking applied by ACC is limited; how-
ever, 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 EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity.
When this occurs, you should immediately apply the
brakes as needed to maintain a safe distance from the
vehicle ahead.
