Take the vehicle to a professional to have it serviced. The
problem(s) causing the red LED to light must be repaired

Audio Tone Interpretation
The audio tone is configured according to the I/M Readiness Status.
This function is invaluable when performing diagnostics and driving
at the same time, or working in bright areas where LED illumination
alone is not sufficient.
Different audio tone with different LED light indicates different I/M
Readiness Status.
