Circuit/System Verification

WARNING: This page is about a different car, the 2012 Buick Verano. However, it is still accessible from the selected car via links, so may be relevant.
  1. Tune to a strong AM or FM station and verify each speaker is producing clear and even sound, with no distortion.
    • If any speaker is not producing sound or the sound produced is distorted, refer to Speaker Malfunction .
  2. With the vehicle outside in an area with an unobstructed view of the southern sky, tune to XM. Verify XM reception is clear and the No XM Signal message is not displayed on the radio.
