Rear Window Wiper/Washer - GMC 2008 Yukon Denali Owner's Manual

Heated Windshield Washer
For vehicles with the heated windshield washer fluid
system it can be used to help clear ice, snow, tree sap,
or bugs from your windshield.
Push the heated washer fluid button to activate the
heated windshield washer fluid system. The indicator
light will flash. This activation initiates four heated
wash/wipe cycles. The first heated wash/wipe cycle may
take up to 40 seconds to occur, depending on outside
temperature. After the first wash/wipe cycle, it may take
up to 20 seconds for each of the remaining cycles to
begin. Press the button again to turn off the heated
windshield washer fluid system or it will automatically
turn off after four wipe cycles have been completed.
When the heated windshield washer fluid system
is activated under certain outside temperature
conditions, steam may flow out of the washer nozzles
for a short period of time before washer fluid is sprayed.
This is a normal condition.
