   • Low Voltage Alarm: Warns if the car battery voltage drops below a safe threshold.
   • Fatigue Driving Reminder: Automatically alerts the driver after 4 hours of continuous driving (configurable).

Advanced Configuration & Compatibility:
   • Speed Calibration: The displayed speed can be fine-tuned to exactly match the car’s dashboard speedometer if there is a discrepancy.
   • Hybrid/Start-Stop Mode: Features adjustable shutdown voltage settings, allowing the HUD to remain functional in Hybrid cars or vehicles with Automatic Start/Stop features where the engine turns off at traffic lights.
   • Auto Power: Automatically powers on and off with the vehicle to protect the car battery.
   • Manual Brightness Control: While auto-brightness is default, users can manually force a brightness level if preferred.
