256 Vehicle Care
Windshield Care
Wax must not be applied to the windshield.
A layer of wax can impair your view in
rainy weather and can also lead to rough
movements of the windshield wiper.
If engine oil or grease comes into contact
with the windshield, staining or discoloration
may result. It must be immediately
cleaned away.
If not fully cleaned by the windshield
wipers, the windshield should be cleaned
using glass cleaner. If your windshield is not
clear after using the windshield washer, or if
the wiper blade chatters when running, wax
or other material may be on the blade or
windshield.
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.
