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.
Seat belt buckle switch
The automatic engine start-stop uses the seat belt buckle switch to identify whether the driver's 3-point automatic-reel belt is closed. If the driver's 3-point automatic-reel belt is not closed, the automatic engine start-stop reacts differently according to the driving condition:
- When the engine is running, a switch-off inhibitor is set and the engine is not stopped.
- If the engine is off the automatic engine start-stop is deactivated. A restart is possibly solely by using the start/stop button.
