3. Lubricate (one drop) hinge joint area in each
vehicle service to achieve proper arm
pressure.
4. Check the wiper blades at least twice a year or
when they seem less effective. Substances
such as tree sap and some hot wax treatments
used by commercial car washes reduce the
effectiveness of wiper blades.
5. If the wiper blades do not wipe properly, clean
both the windshield and wiper blades using
undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water.
To avoid damaging the blades, do not use fuel,
kerosene, paint thinner, or other solvents.
When replacing wiper blade assemblies, always
use specified parts or equivalents. To make
replacing the wipers easy, turn the ignition to
ACC, and then turn the wipers on. When the wiper
reaches the vertical position, turn the ignition to
lock.
