If the warning light is on in the corner of the screen for the SDLG LG946L, it indicates a specific issue depending on which indicator lamp is lit:

- Pre-heat Indicator Lamp: Machine is in preheat mode.
- Parking Brake Indicator Lamp: Parking brake is engaged or brake air pressure is low.
- Charging Indicator Lamp: Engine is off or there is a problem with the storage battery.
- High Beam Indicator Lamp: High beam headlights are on.

Each light signals a different condition that may require attention.
