WINDSHIELD WIPER BLADES
Check the wiper blades for wear 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.
CHECKING WIPER BLADES
Check the wiper blades on your
vehicle for roughness by running the
tip of your fingers over the edge of
the blade.
Traces of grease, silicone and fuel
also prevent wiper blades from
functioning properly. Clean the
blades regularly using a damp cloth
or sponge soaked with diluted
windscreen or car wash detergent.
Change the wiper blades on your vehicle at least once a year.
CHANGING THE WIPER BLADES
To replace the wiper blades:
1. Pull the wiper arm away from the
windshield and lock into the service
position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
manually to release the blade and
pull the wiper blade down toward
the windshield to remove it from the
arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
