Cadillac 2010 DTS Owner's Manual page 173

The Forward Collision Alert (FCA) system provides an
audible and visual alert if you approach a vehicle
too quickly that is directly ahead. FCA also provides a
visual alert with no audible alert if you are following
another vehicle much too closely. The FCA alert symbol
is located on top of the instrument panel to the right
of the driver. FCA uses the Adaptive Cruise Control
radar to detect a vehicle directly ahead, in your path,
within a distance of 328 ft (100 m) and operates at
speeds above 20 mph (32 km/h).
WARNING:
{
FCA is only a warning system and does not apply
the brakes. When you are approaching a vehicle
or object too rapidly or when you are following a
vehicle too closely that is ahead of you, FCA may
not provide you with enough time to avoid a
collision. FCA is not designed to warn the driver of
pedestrians or animals. Your complete attention is
always required while driving and you should be
ready to take action and apply the brakes. For
more information, see Defensive Driving on
page 5-2.
To enable or disable FCA, press the Adaptive Cruise
Control button. See Adaptive Cruise Control on
page 4-15.
The FCA control is located
on the steering wheel.
