The cabin air filter in a Nissan Qashqai is located near the left foot area of the front passenger seat. When replacing the cabin air filter, first remove the fastener by gently pressing it toward the front of the vehicle to avoid breakage, then proceed with the replacement. Below are the steps for replacing the cabin air filter in a Nissan Qashqai: 1. Remove the decorative panel on the right side of the driver's seat; it's easier to start from the top and work downward. 2. The replacement method is the same for both the 2008 and 2010 models. The white obstruction in the 2010 model does not affect filter replacement. The filter cover is attached to gray sealing foam with a handle in the middle. The bottom of the cover has a clip; gently pull it with your finger to remove the cover. 3. Once the cover is removed, you can pull out the cabin air filter. Note: The filter has a front and back side. While OEM filters have markings indicating the front and back, aftermarket filters typically have an extra thin material on one of the short edges of the frame. The correct installation direction is with this extra material facing outward at the top. 4. Installing the filter can be challenging due to the awkward position. You can bend the filter toward the front of the vehicle and, after fully inserting it, pull it back and forth a few times to ensure it's properly seated. Finally, reattach the cover to complete the process.
