Windshield wiper blades should be inspected for wear and cracking. See Scheduled Maintenance for more information.

Replacement blades come in different types and are removed in different ways. For the proper type and length, see Maintenance Replacement Parts.

It is a good idea to clean or replace the wiper blade assembly every six months. Allowing the wiper blade arm to touch the windshield when no wiper blade is installed could damage the windshield. Any damage that occurs would not be covered by the vehicle's warranty. Do not allow the wiper blade arm to touch the windshield.

To remove the wiper blade assembly:

  1. Open the hood to gain access to the windshield wipers.
  2. Lift the wiper arm away from the windshield.
