2. Installation Guide

Before beginning installation, please ensure your vehicle is turned off. Refer to your vehicle's owner's manual for the exact location of the cabin air filter housing, as it can vary by model year and trim.

General Installation Steps:

1. Locate Filter Housing: The cabin air filter is typically located behind the glove compartment or under the dashboard on the passenger side.
2. Access Filter: Open the glove compartment. You may need to unclip or remove the glove compartment entirely to access the filter housing cover.
3. Remove Cover: Unlatch or unscrew the cabin air filter housing cover.
4. Note Airflow Direction: Before removing the old filter, observe the airflow direction arrow printed on its side. This is crucial for correct installation of the new filter.
5. Remove Old Filter: Carefully pull out the old cabin air filter. Dispose of it properly.
6. Insert New Filter: Insert the new CHROX cabin air filter into the housing, ensuring the airflow arrow on the new filter points in the same direction as the old one (usually towards the rear of the vehicle or downwards).
7. Secure Cover: Replace the filter housing cover and re-secure the glove compartment.
8. Test System: Turn on your vehicle and test the air conditioning/heating system to ensure proper airflow.

Installation typically takes less than five minutes and usually requires no specialized tools.

3. Operation

Once installed, the CHROX Cabin Air Filter operates passively as part of your vehicle's heating, ventilation, and air conditioning (HVAC) system. It continuously filters the air entering the cabin, removing airborne particles and odors. No direct user interaction is required for its operation.

4. Maintenance

Regular maintenance of your cabin air filter is essential for maintaining optimal air quality and HVAC system performance.

Replacement Schedule:

• It is generally recommended to replace your cabin air filter every 12,000 to 15,000 miles or once a year, whichever comes first.
• In areas with high pollution, heavy traffic, or dusty conditions, more frequent replacement may be necessary.
• If you notice reduced airflow from your vents, persistent unpleasant odors, or increased allergy symptoms, inspect and potentially replace the filter sooner.

Refer to your vehicle's owner's manual for specific recommendations regarding cabin air filter replacement intervals for your BYD Yuan Plus EV Atto 3.

5. Troubleshooting

If you experience issues related to your cabin air filter, consider the following:

• Reduced Airflow: A clogged filter can restrict airflow. Check if the filter is dirty and replace it if necessary. Ensure the airflow direction arrow was followed during installation.
• Unpleasant Odors: While the activated carbon filter is designed to reduce odors, a heavily saturated or old filter may lose effectiveness. Replace the filter to restore odor filtration.
• Increased Noise from HVAC: A severely clogged filter can cause the blower motor to work harder, potentially leading to increased noise. Replacing the filter may resolve this.

If problems persist after checking and replacing the filter, consult a qualified automotive technician.
