Windshield Washer - Buick 2005 LeSabre Owner's Manual

The Rainsense™ system is activated by turning the
wiper control band to one of the five sensitivity levels
within the delay area. The delay position closest to OFF
is the lowest sensitivity setting, level one. The highest
sensitivity setting, level five, is closest to LO. A
single wipe will occur each time you turn the wiper
control band 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 LO or HI 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.

Windshield Washer

At the top of the turn signal/multifunction lever, there is
a paddle with the word PUSH on it. To spray washer
fluid on the windshield, push the paddle. The wipers will
clear the window and either stop or return to your
preset speed. For more washer cycles, push and hold
the paddle.
CAUTION:
{
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.
Ice build up can block washer nozzles. Remove ice for
proper operation.
See Windshield Washer Fluid on page 5-34 for
