Operating Instructions
Once installed, the rear windshield wiper operates via your vehicle's standard wiper controls. Refer to your vehicle's owner's manual for specific instructions on activating and controlling the rear wiper.
- Activation: Typically, the rear wiper is activated by a lever or switch on the steering column or dashboard.
- Intermittent/Continuous Modes: Most vehicles offer intermittent and continuous wiping modes. Select the appropriate mode based on precipitation intensity.
- Washer Fluid: Use the washer fluid function to clean the rear windshield before or during wiping for optimal visibility.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your wiper arm and blade set.
- Regular Cleaning: Clean the wiper blade and windshield regularly with a soft cloth and glass cleaner to remove dirt, grime, and road film.
- Inspect Blades: Periodically inspect the rubber blade for cracks, tears, or hardening. Replace the blade if any damage is observed or if streaking occurs.
- Winter Care: In freezing conditions, lift the wiper arm off the windshield to prevent the blade from freezing to the glass. Do not operate wipers on a frozen windshield.
- Fluid Levels: Ensure your vehicle's washer fluid reservoir is always adequately filled.
