WIPER BLADES
Blade Inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.

To prevent damage to the wiper blades,
arms or other components, do not:

[Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.

[Attempt to move the wipers
manually.

[Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.

Normal wear of the wipers may not be
covered by your vehicle warranty.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.

hood and the wiper arms, the wiper
arms should only be lifted when in
