- Check the vehicle battery condition first - Refer to: Battery Test (2014 2015), or Battery Test (2016 2017 2018 2019 2020) .

- Set the fan speed to low (1 or 2)
- Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the ceiling
- Pause after pressing the TALK button then give a voice command clearly in a natural speaking voice. If the system cannot recognize your command, speak louder
- If you speak a command with something in your mouth, or your voice is too husky, or high pitched, the system may misunderstand your command
- If possible, have the client demonstrate their concern, then compare it to a known-good vehicle of the same year/trim with the same software version. If the client's concern is duplicated on the known-good vehicle, it is a characteristic of the system.
