Rainsense™ Ii Wipers - Cadillac 2004 DeVille Owner's Manual

Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If the blades do
become damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle is equipped with wiper-activated headlamps.
After the windshield wipers have been on for
approximately six seconds, the headlamps will
automatically turn on. See Wiper Activated Headlamps
under Exterior Lamps on page 3-16 for more information.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior side of the windshield behind the
rearview mirror. It is used to automatically operate the
wipers by monitoring the amount of moisture build-up on
the windshield. Wipes occur as needed to clear the
windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes will
occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense™ wipers operate in a delay
mode as well as a continuous low or high speed as
needed. 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 activated.
3-12
The Rainsense™ system can be activated by turning the
wiper band to one of the five sensitivity levels indicated
on the wiper stalk. 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 LO. 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 cycles operate as normal and are
not affected by the Rainsense™ function. The
Rainsense™ system can be overridden at any time by
manually turning the wiper band to LO or HI speed.
When Rainsense™ is active, the headlamps will turn on
automatically. The headlamps will turn off again once the
wipers turn off if it is light enough outside. If it is dark, they
will remain on. See " Wiper-Activated Headlamps" under
Exterior Lamps on page 3-16 for more information.
Notice: Do not place stickers or other items on the
exterior glass surface directly in front of the
moisture sensor. Doing this could cause the
moisture sensor to malfunction.
