Question 6605
While driving, how does the advanced driver assistance system known as Start-Stop work?
- By shutting off the engine while it is idling when the vehicle comes to a stop.
- By shutting off the engine when the clutch is pressed during any Detention caused by traffic.
- By preventing the engine from restarting automatically when setting off again after each Detention.
Show answer and explanation
Correct answer: By shutting off the engine while it is idling when the vehicle comes to a stop.
Start-Stop shuts off the engine when you stop the car and the engine is idling, for example at a red light. In the image, the car is stopped, the tachometer reads zero, and the system’s green indicator light is on. When you’re ready to move again, it restarts the engine automatically: when you press the clutch with a manual transmission, or release the brake with an automatic transmission. So pressing the clutch doesn’t shut the engine off; it restarts it.
