• For the 2026 Toyota bZ, first confirm any dash messages and check the charging connector is fully seated and undamaged if you recently charged the vehicle.
• Check the 12V auxiliary battery condition and connections; many EV alerts stem from low 12V voltage rather than the high-voltage pack.
• If the light is steady, schedule a diagnostic with our dealership; if the light is flashing or accompanied by loss of power, stop driving and contact us immediately.
