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

Heated Windshield Washer
If your vehicle has the heated windshield washer fluid
system it can be used to help clear ice, snow, tree sap,
or bugs from the windshield. This feature only works
with the front wiper system.
Push the heated washer fluid button to activate
the heated windshield washer fluid system. This
activation begins four heated wash/wipe cycles.
The first heated wash/wipe cycle can take up to
40 seconds to occur, depending on outside temperature.
After the first wash/wipe cycle, it can take up to
20 seconds for each of the remaining cycles. 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.
The button is located
to the left of the
steering column below
the instrument panel
brightness control knob.
When the heated windshield washer fluid system is
activated under certain outside temperature conditions,
steam might flow out of the washer nozzles for a short
period of time before washer fluid is sprayed. This is a
normal condition.
WASHER FLUID LOW ADD FLUID is displayed on the
DIC when the washer fluid is low. See DIC Warnings
and Messages on page 3-66.

Rear Window Wiper/Washer

The rear wiper and rear wash button is located on the
instrument panel below the climate control system.

(Rear Wiper): Press this symbol to turn the rear
wiper on and off. The wiper speed cannot be changed.

the rear window. The window wiper will also come on.
Release the button when enough fluid has been sprayed
on the window. The rear wiper will run a few more cycles
after it is released. If the rear wiper function was already
on, prior to pressing the wash button, it will stay on until
the wiper button is pressed again.
The rear window washer uses the same fluid that is in
the windshield washer reservoir. See Windshield Washer
Fluid on page 5-34.
