Question 8026
What driving assistance does the hill-start assist system or "Hill-Holder" provide?
- It prevents selecting an inappropriate gear on a sloping stretch of road, whether uphill or downhill.
- On an uphill slope, it prevents the vehicle from rolling backward when you lift your foot off the brake.
- On a downhill slope, it prevents the vehicle from reaching a high speed.
Show answer and explanation
Correct answer: On an uphill slope, it prevents the vehicle from rolling backward when you lift your foot off the brake.
When you move off uphill, as on the street in the image, the car tends to roll backward while you move your foot from the brake to the accelerator. Hill Holder detects the slope and holds the car briefly to keep it from rolling backward. It doesn't select the gear or brake the car on downhill slopes.
