Rainsense™ Ii Wipers - Buick 2008 Lucerne Owner's Manual

1 (High Speed): For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9 (Off): To stop the wipers, move the band to off.
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 become worn
or damaged, replace with 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 has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically
turn on. See Wiper Activated Headlamps on page 3-15
for more information.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield beside the
rearview mirror and is used to automatically operate the
wipers. This system operates by monitoring the amount
of moisture build-up on the windshield. Wipes occur as
needed to clear the windshield depending on the driving
conditions and the sensitivity setting. In light rain or snow,
fewer wipes will occur. In heavy rain or snow, wipes will
3-10
occur more frequently. 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 cycles operate 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. Doing this could cause the rain sensor
to malfunction.
