Cadillac 2009 STS-V - Manual (Page 180)

Alerting the Driver
The alert symbol flashes
on the HUD and a warning
beep sounds when driver
action is required.
Driver action is required when:
• Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a vehicle too
rapidly.
• The vehicle speed drops below about
25 mph (40 km/h).
• A temporary condition prohibits Adaptive Cruise
Control from operating. See DIC Warnings and
Messages on page 3-79 for more information.
• A malfunction is detected in the system. See DIC
Warnings and Messages on page 3-79 for more
information.
See Defensive Driving on page 4-2.
{ CAUTION:
Adaptive Cruise Control has only limited braking
ability to slow your vehicle. In some cases,
Adaptive Cruise Control may not have time to slow
your vehicle enough to avoid a collision. Be ready
to take action and apply the brakes yourself.
See Defensive Driving on page 4-2.
Approaching and Following a Vehicle
The vehicle ahead symbol
only appears on the HUD
when a vehicle ahead
is detected in your path.
If this symbol does not appear, or disappears briefly,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
