Windshield Wipers; Rainsense™ Ii Wipers - Buick 2004 LeSabre Owner's Manual

Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass. It
works even if your headlamps are off.
Pull the turn signal lever toward you briefly to
flash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They will stay on as long as
you hold the lever toward you and the high-beam
indicator on the instrument panel cluster will come on.

Windshield Wipers

The windshield wipers are controlled by turning the
band marked WIPER.
If your windshield wipers are on for more than six
seconds while you are driving, the low-beam headlamps,
instrument panel cluster backlighting and taillamps will
turn on. For more information see "Wiper Activated
Headlamps" under Exterior Lamps on page 3-14.
OFF: Turn the band to OFF to turn the wipers off.
MIST: For a single wiping cycle, turn the band to MIST.
Hold it there until the wipers start, then let go. The
wipers will stop after one cycle. If you want more cycles,
hold the band on MIST longer.
LO (Low Speed): Turn the band to LO for steady
wiping at a slow speed.
HI (High Speed): Turn the band to HI for steady wiping
at a high speed.
The wiper speed may be set for a long or short delay
between wipes. Turn the band to choose the delay time.
The closer to LO, the shorter the delay.
Heavy snow or ice can overload your wiper motor. A
circuit breaker will stop the motor until it cools.
Clear away snow or ice to prevent an overload.
Keep in mind that damaged wiper blades may prevent
you from seeing well enough to drive safely. To
avoid damage, be sure to clear ice and snow from the
wiper blades before using them. If your blades do
become damaged, get new blades or blade inserts.
Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield below 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.
