CHEVROLET Tahoe - Manual (Page 209)

The rainsensor will automatically control the
frequency of the wipes from the off setting to the
high speed setting according to the weather
conditions. The wipers can be left in a rainsense
mode even when it is not raining.
When Rainsense™ is active, the headlamps will
turn on automatically if the exterior lamp control is
in the AUTO position.
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.
Windshield Washer
{ 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.

with the windshield washer symbol at the top of the
multifunction lever. To spray washer fluid on the
windshield, push the paddle. The wipers will
clear the window and then either stop or return to
your preset speed.

If your vehicle has the heated windshield washer
fluid system it may be used to help clear ice,
snow, tree sap, or bugs from your windshield.
