254 Vehicle Care
The windshield wipers on your truck can be
pulled out from the windshield to provide
easier access for cleaning.
Clean the outside of the windshield with a
non-abrasive cleaner. Your windshield is
clean if beads do not form when rinsing
with water. Clean the blade by wiping with
a cloth soaked in a solution of one-half
water and one-half methanol alcohol. Then
rinse the blade with water.
The windshield wiper arms may be swung
out, away from the glass, to provide easy
access for cleaning.
In order to prevent damage or water
leakage, do not grip the roof marker lights
while cleaning the windshield.
