If You Cannot See the HUD Image When the Ignition Is On
• Is anything covering the HUD lens?
• Is the HUD dimmer setting bright enough?
• Is the HUD image adjusted to the proper height?
• Are you wearing polarized sunglasses?
• Still no HUD image? Check the fuse in the instrument panel fuse block. See Instrument Panel Fuse Block on page 10‑34.
