Cadillac 2008 XLR Owner's Manual page 141

Make sure the set speed is visible on the HUD so you
know the speed your vehicle will accelerate to if a vehicle
is not detected in your path. Keep in mind speed limits,
surrounding traffic speeds, and weather conditions when
adjusting your set speed.
If your vehicle is in Adaptive Cruise Control when the
traction control system begins to limit wheel spin, the
Adaptive Cruise Control automatically disengages.
See Traction Control System (TCS) on page 5-6 and
®
StabiliTrak System on page 5-8. When road conditions
allow you to safely use it again, the Adaptive Cruise
Control can be turned back on.
Increasing Set Speed While Using
Adaptive Cruise Control
There are two ways to increase the set speed:
•
Use the accelerator to get to the higher speed. Press
the set button at the end of the lever, then release
the button and the accelerator pedal. Your vehicle
will now cruise at the higher speed.
•
Move the Adaptive Cruise Control switch from on to
resume/increase. Hold it there until the desired set
speed is displayed in the HUD, then release the
switch. To increase your set speed in very small
amounts, move the switch briefly to resume/increase.
Each time this is done, your vehicle set speed
increases by about 1 mph (1.6 km/h).
Your vehicle will not reach the set speed until the system
determines there is no vehicle in front of you. At that
point, your vehicle speed will increase to the set speed.
Decreasing Set Speed While Using
Adaptive Cruise Control
Press in the set/decrease button on the end of the lever
until you reach the lower desired speed, then release
the button.
To slow down in very small amounts, briefly press the
set/decrease button. Each this is done, your set
speed will be 1 mph (1.6 km/h) slower.
Resuming a Set Speed
If you apply the brakes while the Adaptive Cruise Control
is at a set speed, this disengages the Adaptive Cruise
Control. But it does not need to be reset.
Once the vehicle reaches about 25 mph (40 km/h) or
more, move the Adaptive Cruise Control switch briefly
from on to resume/increase. Adaptive Cruise Control will
be engaged with the speed selected previously.
