Cadillac 2006 XLR - Manual (Page 132)

Approaching and Following a Vehicle
The vehicle ahead symbol
will only appear on the
HUD when a vehicle ahead
is detected in your path.
If this symbol does not appear, or disappears briefly,
Adaptive Cruise Control will not respond to vehicles you
may see ahead.
{ CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.
Adaptive Cruise Control will automatically slow
your vehicle down when approaching a slower
moving vehicle. It will then adjust your speed to follow
the vehicle in front at the selected follow distance.
Your speed will increase or decrease to follow
the vehicle in front of you but will not exceed the set
speed. The system may apply limited braking if
necessary. When braking is active, your brake lights will
come on. It may feel or sound different than if you
were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{ CAUTION:
Adaptive Cruise Control may not detect and
react to stationary or slow-moving vehicles or
other objects ahead of you. You could crash
into an object ahead of you. Do not use
Adaptive Cruise Control when approaching
stationary or slow-moving vehicles or other
objects.
