Follow these steps to check and replace the cabin air filter:

  1. Locate the Cabin Air Filter Compartment: It’s usually behind the glove box or under the dashboard on the passenger side.
  2. Remove the Glove Box: Open the glove box fully and carefully release the stops or clips holding it in place using a screwdriver if necessary.
