1. Introduction
The S100 OBD Gauge HUD (Head Up Display) is an advanced automotive accessory designed to enhance driving safety and convenience by projecting vital vehicle data directly onto your windshield or displaying it on its integrated screen. This dual-screen design minimizes the need for drivers to look down at the dashboard, keeping their eyes on the road.
It connects to your vehicle's OBD2 port, providing real-time information such as speed, RPM, coolant temperature, fuel consumption, turbo pressure, and voltage. The S100 model also offers additional data like oil temperature, transmission oil temperature, and engine load. With automatic power on/off and adjustable brightness, the S100 offers a seamless and intuitive user experience.

2. Setup and Installation
The S100 HUD is designed for easy plug-and-play installation. Follow these steps to set up your device:
- Locate the OBD2 Port: Identify your vehicle's OBD2 diagnostic port. This is typically located under the dashboard on the driver's side, near the steering wheel.
- Connect the OBD2 Cable: Plug one end of the provided 1.8-meter OBD2 cable into the S100 HUD and the other end into your vehicle's OBD2 port.
- Position the HUD: Place the S100 HUD on your dashboard in a position that does not obstruct your view of the road. Ensure it is stable and secure.
- Apply Reflective Film (Optional for Windshield Projection): If you intend to use the windshield projection feature, clean the desired area on your windshield. Carefully apply the provided HD reflective film to this area. This film enhances the clarity and visibility of the projected display.
- Power On: Start your vehicle's engine. The S100 HUD will automatically power on and begin displaying data.

3. Operating Instructions
3.1. Display Modes
The S100 features a unique dual-screen design, offering both a direct dashboard display and a windshield projection. Data can be switched between these two screens as preferred.
Figure 3: The S100 HUD offers both a direct display and a windshield projection for enhanced visibility.
3.2. Displayed Information
The S100 HUD provides a comprehensive range of vehicle data:
- Common Display Data: Vehicle Speed, RPM, Coolant Temperature, Fuel Consumption, Turbo Pressure, Voltage.
- S100 Extra Display Data: Oil Temperature, Transmission Oil Temperature, Engine Load.

3.3. Unit Switching
You can freely switch between different units for speed and temperature:
- Speed Unit: KM/H (Kilometers per Hour) and MPH (Miles per Hour).
- Temperature Unit: ℃ (Celsius) and ℉ (Fahrenheit).
- Distance Unit: M (Meters) and MILE (Miles).
- Altitude Unit: M (Meters) and FT (Feet).

3.5. Alarms and Warnings
The device provides multiple alarms to alert you to critical vehicle conditions:
- Over Speed Alarm
- RPM Alarm
- Water Temperature Alarm
- Voltage Alarm
- Turbine Pressure Alarm
- Engine Oil Temperature Alarm
- Oil Pressure Alarm
- Gearbox Oil Temperature Alarm
These alarms are indicated by atmosphere light linkage, gradually flashing from the middle to both sides, and accompanied by a beeping sound.

3.6. Real-time Vehicle Status Monitoring
The S100 HUD continuously monitors key engine parameters, providing real-time insights into your vehicle's health:
- Engine Oil Temperature: Real-time inspection of engine oil temperature to test the engine lubrication system.
- Gearbox Oil Temperature: Monitoring to prevent damage from excessively high transmission oil temperature.
- Oil Pressure: Monitoring to avoid engine cylinder loss caused by oil shortage.
- Engine Load: Helps in understanding the current load on the engine, useful for avoiding over-negative engine operation.

4. Maintenance
To ensure the longevity and optimal performance of your S100 HUD, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe the display screen and the device body. Avoid using abrasive cleaners or solvents, as these can damage the surface.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Handle the OBD2 cable with care. Avoid sharp bends or excessive pulling, which can damage the internal wiring.
- Environmental Conditions: The device is designed for in-car use. Avoid exposing it to water, high humidity, or extreme heat/cold.
5. Troubleshooting
If you encounter any issues with your S100 HUD, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device not powering on | OBD2 cable not properly connected; Vehicle's OBD2 port not supplying power; Vehicle not compatible. | Ensure the OBD2 cable is securely plugged into both the HUD and the vehicle's port. Start the engine. Verify vehicle compatibility (most OBD2 models after 2008 are supported). |
| Inaccurate speed reading | Incorrect speed unit selected; Calibration needed. | Check if the speed unit (KM/H or MPH) is correctly set. Refer to the full instruction manual for speed calibration procedures if necessary. |
| Windshield projection is blurry or ghosted | Reflective film not applied correctly or not used; Windshield angle. | Ensure the HD reflective film is applied smoothly and correctly. Adjust the device's angle on the dashboard. |
| Device does not clear fault codes | This model may not support fault code clearing directly. | The S100 HUD is primarily a display and monitoring unit. While it reads data, direct fault code clearing functionality is not explicitly listed for this model. For fault code clearing, a dedicated OBD2 scanner tool is typically required. |
If the problem persists, please contact customer support for further assistance.
