To replace the wiper blade assembly: 1. Turn the ignition to ON/RUN with the engine off. 2. Turn on the windshield wipers and turn them off again when the wipers are in the out-wipe position. The driver side blade will be straight up and down on the windshield. 3. Pull the windshield wiper assembly away from the windshield. 4. Lift up the wiper blade assembly cap. 5. Pull the wiper blade assembly down far enough to release it from the J-hooked end of the wiper arm. Slide the assembly away from the arm. 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 your warranty. Do not allow the wiper blade arm to touch the windshield.

Do this until the vehicle is held by the parking brake only. To check the P (Park) mechanism's holding ability: With the engine running, shift to P (Park). Then release the parking brake followed by the regular brake. . Contact your dealer/retailer if service is required.
