Cadillac 2009 DTS Automobile User Manual


 
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.
Decreasing Set Speed While Using ACC
Press the SET– button until you reach the lower speed
desired, then release it.
To slow down in very small amounts, briefly press the
SET– button. Each time this is done, the set speed
decreases by 1 mph (1 km/h) slower.
Resuming a Set Speed
Suppose the ACC is set at a desired speed and then
the brakes are applied. This will turn off the ACC.
But it does not need to be reset.
Once the vehicle speed reaches about 25 mph (40 km/h)
or more, press the +RES button. ACC will be engaged
with the previously chosen set speed.
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain 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.
There are six follow distances to choose from.
The follow distance selection ranges from near to far
(one second to two seconds follow time). The distance
maintained for a selected follow distance will vary based
on vehicle speed. The faster the vehicle speed the further
back your vehicle will follow. Consider traffic and weather
conditions when selecting the follow distance. The range
of selectable distances may not be appropriate for all
drivers and driving conditions. If you prefer to travel at
a follow distance farther than ACC allows, disengage
the system and drive manually.
