Maintenance and care Checking wiper blades Check the wiper blades on your vehicle for roughness by running the tips of your fingers over the edge of the blade. Traces of grease, silicone and fuel prevent wiper blades from functioning properly. We recommend Ford cleaning solutions or equivalent to clean wiper blades. Change the wiper blades on your vehicle at least once a year. Cabin air filter replacement In your climate control system, you have a filter that cleans the air before it enters the interior of the vehicle. This filter should be replaced at the intervals in the Scheduled Maintenance Guide". To replace the cabin air filter: 1. Remove both windshield wiper arms. With the wiper arm in the horizontal position, lift the arm away from the windshield while pulling the retaining clip at the base toward the windshield. Release the wiper arm, then lift it off the base. 193
