Installation Guide

The following steps outline a straightforward installation process that can be completed by a qualified technician or an experienced driver during routine maintenance checks.

1. Locate the Filter Housing: Identify the cabin air filter compartment, typically situated behind the glove box or under the dashboard on the passenger side.
2. Remove the Old Filter: Open the housing cover and gently pull out the existing filter. Dispose of it according to local environmental guidelines.
3. Inspect the Housing: Check for any debris, moisture, or damage that could affect performance. Clean the interior surfaces if necessary.
4. Insert the CU 5673: Align the filter’s mounting tabs with the housing slots and slide it in until it clicks into place. Ensure the filter is seated fully to avoid airflow gaps.
5. Secure the Cover: Replace the housing cover, tightening any screws or latches according to manufacturer specifications.
6. Verify Airflow: Start the vehicle and confirm that cabin ventilation functions normally. Listen for any unusual noises indicating a blockage.

Maintenance Tips

• Check the filter every 12,000 km or after prolonged exposure to dusty environments.
• Avoid using compressed air to clean the filter; this can damage the media layers.
• If you notice a significant drop in cabin temperature or increased HVAC noise, replace the filter promptly.
