Buick 2009 Lucerne - Manual (Page 150)

Windshield Wipers
Turn the band with the wiper symbol on it to control the
windshield wipers.
8 (Mist): For a single wiping cycle, hold it on mist
until the wipers start, then release. The wipers stop after
one wipe. For more wipe cycles, hold the band longer.
6
(Delay): Use to set the delay time between wipe
cycles. The wiper speed can be set for a long or short
delay between wipes. The closer the band is set to
the top of the lever, the shorter the delay.
6 (Low Speed): For steady wiping at low speed.
1 (High Speed): For high-speed wiping.
9 (Off): Turns the wipers off.
Clear ice and snow from the wiper blades before using
them. If the wipers are frozen to the windshield,
carefully loosen or thaw them. If they 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.
The 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 3-16
for more information.
Rainsense™ II Wipers
If the 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
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.
