Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Protection Function
When battery voltage malfunctions temporarily and system overheats continuously, system changes to protection state. Steering assist control operation stops temporarily. This is not a system malfunction. By stopping steering wheel operation for a short period of time when system is overheating, temperature drops and system returns to normal state automatically.
