The BOSCH AeroTwin wiper blades are designed for specific vehicle applications. Always ensure the correct blade lengths and adapter types for your vehicle before installation. Refer to your vehicle's owner's manual for specific wiper arm service positions.

- Prepare the Vehicle: Turn off the ignition and lift the wiper arm away from the windshield until it locks into the service position. Place a towel or cardboard on the windshield to prevent damage if the arm accidentally falls.
- Remove Old Blade: Locate the release tab or button on the existing wiper blade's connector. Press or lift the tab and slide the old blade off the wiper arm. Be careful not to let the metal wiper arm snap back onto the windshield.
- Identify New Blade: Determine which new blade (26-inch or 22-inch) corresponds to the wiper arm you are working on.
- Install New Blade: Align the pre-assembled adapter of the new BOSCH AeroTwin blade with the hook on the wiper arm. Slide the blade onto the arm until it clicks securely into place. Gently pull on the blade to ensure it is firmly attached.
- Repeat for Second Blade: Follow the same steps for the other wiper blade.
- Test Operation: Carefully lower both wiper arms back onto the windshield. Turn on the ignition and test the wipers with windshield washer fluid to ensure proper function and a clear, streak-free wipe.
Operation
Once properly installed, the BOSCH AeroTwin wiper blades operate in conjunction with your vehicle's existing windshield wiper system. Activate your vehicle's wipers as needed for clear visibility during rain, snow, or when cleaning the windshield. The asymmetrical wind spoiler is designed to maintain optimal contact with the windshield even at higher speeds.
Maintenance
Regular maintenance helps extend the life and performance of your wiper blades.
- Clean Blades Regularly: Wipe the rubber edge of the wiper blades with a soft cloth or sponge dampened with windshield washer fluid or mild soapy water. This removes dirt, grime, and road film that can cause streaking.
- Inspect for Damage: Periodically check the rubber element for cracks, tears, or hardening. Replace blades if any damage is observed.
- Avoid Harsh Chemicals: Do not use petroleum-based cleaners or solvents on the wiper blades, as these can degrade the rubber.
- Clear Windshield: Ensure your windshield is free of heavy ice or snow before operating wipers to prevent damage to the blades and wiper motor.
