Position and release
Put the wipers into their vehicle-specific fold-out position, then raise the arms. Press the retaining clip on the blade fitting and slide the existing blade upward out of the fitting. Use the owner’s manual for the fold-out command if it is unfamiliar.

Repeat and finish
Replace the second blade the same way. Before returning the arms to their operating position, verify both mechanical retainers and hose connections are seated. Complete the vehicle’s fold-in procedure before operating the wipers. A compatible blade and a secure hose connection are both required.
