Cadillac 2007 XLR - Manual (Page 163)

Using Adaptive Cruise Control on Hills
How well Adaptive Cruise Control will work on hills
depends on your speed, vehicle load, traffic
conditions and the steepness of the hills. It may
not detect a vehicle in your lane while driving
on hills. When going up steep hills, you may want
to use the accelerator pedal to maintain your
speed. When going downhill, you may have to
brake to keep your speed down. Applying
the brake disengages the system. You may
choose not to use Adaptive Cruise Control on
steep hills.
Disengaging Adaptive Cruise Control
To disengage the system, apply the brake pedal
or move the Adaptive Cruise Control switch to
off. Adaptive Cruise Control information will
not appear on the HUD when the system is not
engaged.
Erasing Set Speed Memory
When you turn the Adaptive Cruise Control switch
or the ignition off, the set speed memory is
erased.
Other Messages
There are three messages that may appear in the
Driver Information Center (DIC). They are
SERVICE RADAR CRUISE, CRUISE NOT READY
and CLEAN RADAR CRUISE. These messages
will only appear to indicate a problem if Adaptive
Cruise Control is active. See DIC Warnings
and Messages on page 206 for more information.
You may also see CRUISE SPEED LIMITED
displayed in the HUD. See Head-Up Display
(HUD) on page 171 for more information.
