Windshield Washer - Chevrolet 2001 Impala Owner's Manual

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.
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.

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. The ignition key must be in ACC or ON
for this to work. See "Windshield Washer Fluid" in
the Index.

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.
