Cadillac 2009 STS-V - Manual (Page 182)

Low-Speed Deactivation
If your speed falls below 25 mph (40 km/h) while
following a vehicle ahead, Adaptive Cruise Control will
begin to disengage. The driver alert symbol on the HUD
will flash and the warning beep will sound. The driver
must take action since Adaptive Cruise Control will
not slow the vehicle to a stop.
Deactivation When Head-Up Display is
Turned Off
If the HUD is turned off when Adaptive Cruise Control
is engaged, it will begin to disengage. A warning beep
sounds and the message RADAR CRUISE NOT READY
appears on the Driver Information Center (DIC). See DIC
Warnings and Messages on page 3-79 for additional
information. If Adaptive Cruise Control was braking when
the HUD is turned off, the braking will continue briefly.
Passing a Vehicle/Adaptive Cruise Control
Override
To increase speed to pass a vehicle, use the
accelerator pedal. While you are doing this, the
system will not automatically apply the brakes.
A PEDAL APPLIED ACC OVERRIDE message will
appear on the HUD. See Head-Up Display (HUD) on
page 3-43 for additional information. Once you pass
the vehicle and remove your foot from the accelerator
pedal, Adaptive Cruise Control returns to normal
operation and the brakes can be applied, if needed.
{ CAUTION:
If you rest your foot on the accelerator pedal, the
system will not automatically apply the brakes.
You could crash into a vehicle ahead of you.
Do not rest your foot on the accelerator pedal
when using Adaptive Cruise Control.
