Nissan Sentra B18 (2020-2025) Owner's Manual: Automatic Emergency Braking (AEB) with Pedestrian Detection

WARNING

Failure to carefully follow all warnings and instructions for proper use of the Automatic Emergency Braking (AEB) with Pedestrian Detection system could result in serious injury or death.

• The AEB with Pedestrian Detection system on the Nissan Sentra is a supplemental driver assistance feature. It does not replace the driver’s responsibility to remain attentive to traffic conditions and operate the vehicle safely at all times.

  The system cannot prevent accidents caused by inattentive driving, improper vehicle operation, or unsafe driving behavior.

• The AEB with Pedestrian Detection system does not operate in all driving, traffic, weather, or road conditions, and system performance may vary depending on the environment.

The Automatic Emergency Braking with Pedestrian Detection system on the Nissan Sentra is designed to assist the driver when there is a potential risk of a forward collision with a vehicle traveling ahead in the same lane or with a pedestrian detected ahead in the travel path.

The AEB with Pedestrian Detection system uses a forward-facing radar sensor B located at the front of the Nissan Sentra to measure the distance and relative speed of vehicles ahead in the same lane. For pedestrian detection, the system also relies on a camera A installed behind the windshield, working together with the radar sensor to identify pedestrians in the vehicle’s path.

AEB with Pedestrian Detection system operation

For vehicles with the 7 inch meter display

1. Vehicle ahead detection indicator
2. AEB with Pedestrian Detection emergency warning indicator
3. AEB with Pedestrian Detection system warning light

The AEB system on the Nissan Sentra operates at vehicle speeds above approximately 3 mph (5 km/h). For pedestrian detection functionality, the system operates within a speed range of approximately 6–37 mph (10–60 km/h).

If a potential forward collision is detected, the AEB with Pedestrian Detection system initially alerts the driver by flashing the vehicle-ahead detection indicator (yellow) in the vehicle information display and sounding an audible warning. If the driver applies the brakes firmly and quickly after this warning, and the system determines that a collision risk still exists, the system will automatically increase braking force to assist in reducing impact severity.

For vehicles with the 4.2 inch meter display

If the driver does not respond to the initial warning, the AEB with Pedestrian Detection system issues a second visual warning (flashing red and white) along with an audible alert. If the accelerator pedal is released, the system applies partial braking. If the risk of collision becomes imminent, the system will automatically apply stronger braking to help reduce vehicle speed.

While the AEB with Pedestrian Detection system is actively braking, a braking sound may be heard. This is normal and indicates that the Nissan Sentra’s braking system is functioning as intended.

NOTE:

The vehicle’s brake lights will illuminate whenever braking is applied by the AEB with Pedestrian Detection system.

Depending on vehicle speed, distance to the vehicle or pedestrian ahead, road conditions, and surrounding traffic, the system may help avoid a forward collision or help mitigate the severity of an unavoidable impact.

If the driver is actively steering, accelerating, or braking, the AEB with Pedestrian Detection system may respond later or may not intervene.

The automatic braking function will cease under the following conditions:

• When the steering wheel is turned to avoid a collision.
• When the accelerator pedal is depressed.
• When a vehicle or pedestrian is no longer detected ahead.

If the AEB with Pedestrian Detection system brings the Nissan Sentra to a complete stop, the vehicle will remain stationary for approximately 2 seconds before brake pressure is released.
