Buick 1998 Century Owner's Manual page 112

For steady wiping at low speed, turn the band to LO. For
high-speed wiping, turn the band further, to HI. To stop
the wipers, turn the band to OFF.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the band to choose the delay time. The
closer to LO, the shorter the delay between wipes.
Windshield Washer
At the top of the multifunction lever, there's a paddle with
the word PUSH on it. To spray washer fluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your preset
speed. See "Windshield Washer Fluid" in the Index.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
A
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
The LOW WASH light on
your instrument panel
cluster will glow when the
LOW WASH
fluid level is low.
