Installation Guide

1. Locate the Cabin Air Filter Compartment: Open the vehicle’s hood and locate the plenum chamber cover beneath the dashboard area. The filter is positioned directly under this cover.
2. Remove the Old Filter: Gently pull the existing filter out of its housing. Dispose of it responsibly, as it contains captured contaminants.
3. Insert the New CUK 3540 Filter: Align the filter’s edges with the housing and slide it in until it sits flush. Ensure that the active charcoal side faces the airflow direction indicated by the vehicle’s airflow arrows.
4. Secure the Cover: Replace the plenum chamber cover, tightening any screws or clips as required to seal the compartment.
5. Verify Airflow: Start the engine and turn on the HVAC system. Check that air flows smoothly through the vents without unusual resistance.

Maintenance Tips

• Replace the filter every 12–15 months, or sooner if you drive in heavily polluted environments.
• Inspect the filter housing for cracks or damage before installation; replace if necessary to maintain a proper seal.
• Avoid using compressed air to clean the filter, as this can dislodge fine media and reduce filtration efficiency.
