- Locate the small tab or button on the underside of the old wiper blade where it connects to the wiper arm. Press this tab and slide the old blade off the hook.
- Carefully lower the wiper arm onto a towel or soft cloth on the windshield to prevent damage if it accidentally springs back.
- Install New Wiper Blade:

- Align the pre-assembled adapter of the new Bosch AeroTwin blade with the hook on the wiper arm.
- Slide the wiper blade onto the hook until it clicks securely into place. Gently pull on the blade to ensure it is firmly attached.
- Test Wiper Blades:

5. Operating Instructions
Once installed, operate your Bosch AeroTwin wiper blades as you would any standard wiper system. Activate your vehicle's windshield wiper controls for intermittent, low, or high-speed wiping as needed. For optimal performance, ensure your windshield is clean of heavy debris before operating the wipers.
6. Maintenance
- Regular Cleaning: Periodically clean the rubber blade elements with a soft cloth and windshield washer fluid or mild soapy water to remove dirt, grime, and road film. This helps maintain optimal wiping performance and extends blade life.
- Inspection: Regularly inspect the wiper blades for signs of wear, such as cracks, tears, or hardening of the rubber. Also check for any damage to the beam structure or adapter.
- Replacement: Wiper blades typically need to be replaced every 6 to 12 months, depending on usage and environmental conditions. Replace them sooner if you notice streaking, chattering, or incomplete clearing of the windshield.
