Inspection

If part of the head-up display image is distorted or not within the driver's line of sight, the Global Diagnostic System (GDS) can be used to perform calibration.

1. 1
   When Calibration is Necessary

   • When replacing the head-up display.
   • If the image is distorted after windshield replacement (double vision is eliminated after installing the film inside the windshield).
   • When the main warning panel installed on the HUD is removed/installed or replaced.
   • When the installation position of the head-up display video unit is not at the driver's eye level and the focus is inconsistently shifted.
