Cadillac 2007 XLR - Manual (Page 164)

Cleaning the System
The radar can become blocked by snow, ice or
dirt. If so, you may need to turn off the engine and
clean the lens.
The lens is located on the driver’s side of the front
fascia.
Clean the surface with a 50/50 mixture of isopropyl
alcohol and water on a dampened cloth. After
cleaning the fascia lens, try to engage Adaptive
Cruise Control. If this does not fix the problem, you
may have to remove the fascia lens and clean
the inside of the fascia lens and radar lens.
To clean the inside of the fascia lens and radar
lens, insert a tool into one of the small slots on the
inboard side of the lens and pop the lens out.
Clean the surface with a 50/50 mixture of isopropyl
alcohol and water on a dampened cloth. After
cleaning the lens, set the lens back in place and
press until it snaps in.
Exterior Lamps
The exterior lamp control is located to the left of
the steering wheel on the multifunction lever.
