1. Preparation

Tools Required:
- Screwdriver set
- Vacuum cleaner with a hose attachment
- Moisture meter
- Cleaning cloths
- Mild disinfectant spray (preferably automotive-specific)
Safety Warnings:
- Ensure the vehicle is parked in a well-ventilated area.

2. Cabin Air Filter Replacement

Locate the cabin air filter access panel (usually behind the glove compartment).
Remove the screws or clips securing the panel.
Take out the old cabin air filter and inspect it for dirt or moisture.
Install a new cabin air filter, ensuring it is oriented correctly.

3. Clean and Dry the Interior

Use a vacuum cleaner to remove any debris or moisture from the carpets and upholstery.
If damp, use a moisture meter to identify wet spots and dry them using a dehumidifier or fans.
Spray a mild disinfectant on the upholstery and carpets to eliminate mold spores and odors.

4. Inspect and Clear Drainage Systems

For sunroof models, check the sunroof drains by pouring a small amount of water near the sunroof edges and ensuring it flows out underneath the vehicle.
Clear any blockages in the A/C drain tube by gently inserting a flexible wire or compressed air to ensure proper drainage.

5. Check HVAC System

Run the A/C and heater to ensure proper airflow and check for any remaining odors.
If necessary, perform a deep clean of the HVAC system using a specialized HVAC cleaner, following the product instructions.
