Question 6606
How will the hill-start assist system help the driver?
- It will automatically apply the parking brake and will not release it until the driver presses the accelerator, thus preventing the vehicle from rolling backward.
- Through a sensor that detects the vehicle’s angle of incline and prevents it from rolling backward when the driver lifts their foot off the brake.
- It will quickly rev the engine to prevent the vehicle from rolling backward when the driver lifts their foot off the brake.
Show answer and explanation
Correct answer: Through a sensor that detects the vehicle’s angle of incline and prevents it from rolling backward when the driver lifts their foot off the brake.
Hill Holder has a sensor that detects the car’s incline. When you’re stopped facing uphill and lift your foot off the brake to move off, it holds the car briefly, just long enough for you to move your foot to the accelerator without rolling backward in the direction of the red arrow in the image. It only holds the car for a short time and doesn’t rev the engine for you.
