Setting The Gap Distance - Lincoln 2009 MKS Owner's Manual

The vehicle brakes will be automatically applied to slow the vehicle to
maintain a safe distance between the vehicle in front. The maximum
braking which is applied by the ACC system is limited and can be
overridden by the driver applying the brakes.
Note: If the ACC system predicts that its maximum braking level will not
be sufficient, then an audible warning will sound while the ACC
continues to brake. This is accompanied by DRIVER INTERVENE
displayed in the message center. The driver should take immediate
action.
Note: The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING: Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.
