Cadillac 2010 DTS - Manual (Page 177)

The system operates in the delay mode. If the system is
left on for long periods of time, occasional wipes may
occur without any moisture on the windshield. This
is normal and indicates that the Rainsense
™ system
is active.
The Rainsense ™ system is activated by turning the
wiper control band to one of the five sensitivity levels
within the delay area. The position closest to off is
the lowest sensitivity setting, level one. This allows more
rain or snow to collect on the windshield between
wipes. Turning the wiper band away from you to higher
sensitivity levels increases the sensitivity of the
system and frequency of wipes. The highest sensitivity
setting, level five is closest to low. A single wipe will
occur each time you turn the wiper stalk to a higher
sensitivity level to indicate that the sensitivity level has
been increased.
Notice: Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The MIST and wash cycle operates as normal and are
not affected by the Rainsense
™ function. The system
can be overridden at any time by manually changing the
wiper control to low or high speed.
Notice: Do not place stickers or other items on the
exterior glass surface directly in front of the rain
sensor.

In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
