Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade
Check” under Owner Checks and Services on page 6-8
for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
see Normal Maintenance Replacement Parts on
page 6-13.
Here’s how to remove the wiper blades:
1. Turn the wipers on to the lowest intermittent setting.
2. Turn off the ignition while the wipers are at the
outer positions of the wipe pattern. The blades
are more accessible for removal/replacement while
in this position.
3. Pull the windshield wiper arm away from the
windshield or backglass.
4. While holding the wiper arm away from the glass,
push the release clip from under the blade.
