Toyota Yaris Dashboard Warning Lights

Japanese car maker Toyota has been manufacturing the Yaris since 1999. The Toyota Yaris dashboard warning lights detailed below cover the latest two generations and show a symbol, what the warning symbol means and in some cases, what to do based on the manufacturers recommendations.
