Which feature allows the 2022 Nissan LEAF to brake automatically when detecting an obstacle ahead?

1. Traction control

2. Lane departure warning

3. Automatic Emergency Braking

4. Adaptive cruise control

The correct answer is: Automatic Emergency Braking

The feature that allows the 2022 Nissan LEAF to brake automatically when it detects an obstacle ahead is Automatic Emergency Braking. This advanced safety system is designed to help prevent or mitigate collisions by automatically applying the brakes if the vehicle detects an imminent crash situation. When the forward-facing sensors and cameras detect an object or another vehicle in the path of the LEAF, this system assesses the situation in real-time. If it determines that a collision is likely, it engages the brakes to reduce the speed or stop the vehicle entirely, thereby minimizing the impact or even avoiding the accident altogether. In contrast, traction control helps maintain traction on slippery surfaces, while lane departure warning alerts the driver if the vehicle unintentionally drifts out of its lane. Adaptive cruise control can adjust the speed of the vehicle based on the traffic ahead, but it does not specifically engage the brakes to avoid a collision without additional driver intervention. Thus, Automatic Emergency Braking is uniquely designed for the automated detection and response to potential collision events.
