Cadillac 2011 DTS Owner's Manual page 180

The on symbol is located on the display at the top of the
instrument panel to the right of the driver. When the on
symbol is lit on the display, it indicates that ACC is
active.
A message on the DIC will also display when ACC is
set. See DIC Warnings and Messages on page 4 65.
Keep in mind speed limits, surrounding traffic speeds,
and weather conditions when adjusting your set speed.
If the vehicle is in ACC when the traction control system
begins to limit wheel spin, the ACC will automatically
disengage. See Traction Control System (TCS) on
page 5 6 and StabiliTrak
When road conditions allow you to safely use it again,
the ACC can be turned back on.
If the ACC is already activated,
Press the +RES button. Hold it there until the
desired set speed is displayed on the Driver
Information Center (DIC), then release the switch.
To increase the set speed in small amounts, move
the switch briefly to +RES. Each time this is done,
the set speed increases by 1 km/h (1 mph).
Your vehicle will not reach the set speed until the
system determines there is not a vehicle in front of you.
At that point, your vehicle speed will increase to the set
speed.

If the ACC is already activated,
Press the SET button until the lower speed
desired is reached, then release it.
To slow down in small amounts, briefly press the
SET button. Each time this is done, the set speed
decreases by 1 km/h (1 mph) slower.
If the ACC is set at a desired speed and then the
brakes are applied, the ACC is disengaged without
erasing the set speed from memory.
Once the vehicle speed is 40 km/h (25 mph) or greater,
press the +RES button. The vehicle returns to the
previously set speed and stays there.
When the system detects a slower moving vehicle, it
adjusts your vehicle speed and maintains the follow
distance (gap) you select.
Use the plus and minus buttons on the steering wheel
to adjust the follow distance.
Press the plus button to increase the distance or the
minus button to decrease the distance. The first button
press shows the current follow distance setting on
the DIC. The current follow distance setting will be
maintained until it is changed.
