Safety Information
Always prioritize safety when working on your vehicle. Failure to follow these guidelines may result in injury or damage to your vehicle.

- Exercise caution when lifting the wiper arm, as it is spring-loaded and can snap back, potentially causing injury or damaging the windshield.
- Avoid pinching fingers or hands between the wiper arm and the blade or windshield during installation.
- Properly dispose of the old wiper blade according to local regulations.
- Do not operate the wiper blade on a dry windshield, as this can damage the blade and scratch the glass.

Setup and Installation
Follow these steps for a quick and hassle-free installation of your new BOSCH A340H rear wiper blade. This blade features integrated rear quick-clip connections for easy fitment.
- Prepare the Vehicle: Turn off the vehicle's ignition. Gently lift the rear wiper arm away from the windshield until it locks into the upright position. If your wiper arm does not lock, hold it firmly during the entire process or place a towel on the windshield to prevent damage if the arm accidentally snaps back.
- Remove the Old Wiper Blade:
Locate the release tab or button on the existing wiper blade's connector. Depending on your vehicle's specific adapter, you may need to press a tab, squeeze clips, or slide the blade off the arm. Carefully slide the old blade off the wiper arm. Note the orientation of the old blade to assist with installing the new one.

Slide the new blade onto the arm until you hear a click, indicating it is securely locked into place. Gently tug on the blade to ensure it is firmly attached and will not detach during operation.

- Lower the Wiper Arm: Carefully lower the wiper arm back onto the windshield. Ensure it rests flat against the glass.
- Test Operation: Turn on your vehicle's ignition and activate the rear wiper to ensure it operates smoothly and clears the windshield effectively. Apply windshield washer fluid during the test to prevent dry wiping.

Maintenance
Regular maintenance helps extend the life and performance of your wiper blade.
- Clean Regularly: Wipe the rubber blade element with a damp cloth or a paper towel soaked in windshield washer fluid to remove dirt, grime, and road film. This prevents streaking and extends blade life.
- Inspect for Damage: Periodically check the rubber blade for cracks, tears, or hardened spots. Also, inspect the wiper arm for any bends or damage that might affect blade pressure.
- Avoid Ice Scrapers: Do not use ice scrapers on the rubber blade, as this can cause damage. Clear heavy ice and snow from the windshield before operating the wipers.
- Replace When Needed: Wiper blades typically need replacement every 6 to 12 months, or sooner if you notice streaking, skipping, chattering, or reduced visibility.
