Nissan Leaf 2018-2025 (ZE1) Owner's Manual : Rear Automatic Braking (RAB)

WARNING

Failure to strictly adhere to the safety warnings and operational instructions regarding the Rear Automatic Braking (RAB) system in your Nissan Leaf could result in a collision, causing serious personal injury or even death.

  • The RAB system is designed strictly as a supplemental driver-assistance aid; it is not a substitute for standard safe driving procedures.

    Always utilize your side and rearview mirrors, and physically turn your head to check your surroundings in the direction of travel before and during all reversing maneuvers. Never rely exclusively on the RAB system to prevent obstacles from entering your path.

    It remains your fundamental responsibility as the driver to remain vigilant, drive defensively, and maintain absolute control of your Nissan Leaf at all times.

  • Recognize that the RAB system has inherent operational limitations and may not be effective in every possible backing scenario.
  • Environmental factors, including inclement weather, or proximity to external ultrasonic interference—such as those produced by automatic car washes, a heavy truck's compressed-air brakes, or the use of industrial pneumatic drills—may significantly impair system function, leading to reduced performance or unexpected false activations.

The Rear Automatic Braking (RAB) system provides an essential layer of safety by assisting the driver during reversing maneuvers when the vehicle detects solid objects directly behind it.

The RAB system utilizes a series of dedicated parking sensors (1) integrated into the rear bumper of your Nissan Leaf to identify and monitor potential obstacles positioned behind the vehicle.

Note: While you can independently and temporarily disable the audible sonar parking function through the vehicle settings, the core RAB system will remain active to provide emergency braking assistance.
