Inspection

If part of the image on the projection display is distorted or is not at the driver's eye level, use the global diagnostic system (diagnostic tool) to perform calibration.

1. 1
   When Calibration is Necessary

   • When replacing the head-up display.
   • If the image is distorted after windshield replacement (double image is eliminated after the film is attached to the inside of the glass).
   • When removing/installing or replacing the main cluster panel mounted on the HUD.
   • When the head-up display video unit installation position is not at the driver's eye level and focus is inconsistent.

   Calibration Items

   No	Video Calibration Functions	Calibration Cases
   1	Rotation: calibrate in a semicircle / clockwise direction based on the center
   2	Smile: Calibrates vertically at the center.
   3	Tilt (up/down): Calibrates according to the up/down tilt.
   4	Tilt (left/right): Calibrates according to the left/right tilt.
   5	Parallel Compensation
   6	Moving the mark up/down: Compensate according to the eye height.
   7	Initialization: Returns to the state before video compensation.
   8	Video
   9	Height

Troubleshooting

Troubleshooting

Category	Symptom Errors	Inspection Item	Detailed Inspection Item	Related Parts
Lighting	HUD does not operate Illumination brightness is not automatically adjusted (no difference between day and night).	Check the lighting control. Check the operation of the ambient light sensor. Check CAN communication.	Check the illumination control in the cluster (USM). If the HUD operates, there is no problem. Check the ambient light sensor operation → If the ambient light sensor operates, check the communication (CGW ↔ ICU)	Light sensor CGW Cluster
Adjustment Function	Display position is not adjusted.	Check the mirror movement with the IG switch on or off (parking position).	If the stepper motor does not operate with the ignition ON or OFF, the HUD stepper motor is faulty. If the stepper motor in the HUD operates with the ignition ON or OFF, check the CAN communication (cluster ↔ HUD).	HUD Cluster
