WARNING

The following points outline critical limitations of the Rear Automatic Braking (RAB) system in your Nissan Leaf. Failure to understand and respect these operational boundaries, or ignoring the necessity of active driver involvement, could lead to serious injury or fatal accidents.

• Be aware that if you depress the accelerator or brake pedal while the Nissan Leaf is approaching an obstacle, the RAB function may be delayed or may not trigger at all. System performance can also be compromised by various environmental and operational variables, including specific vehicle conditions, complex traffic surroundings, adverse weather, or difficult road surface textures. Do not rely on the system to stop the vehicle automatically; remain ready to apply the brake pedal manually the moment you perceive a risk.
• Should you need to override an active RAB braking event—such as when maneuvering in tight but safe spaces—apply firm, decisive pressure to the accelerator pedal to maintain vehicle movement.
• Always maintain full situational awareness by checking your mirrors and physically looking behind your vehicle throughout the entire reversing process. The RAB system is engineered to detect stationary objects, but it is not infallible and cannot identify every type of obstacle. Specifically, the system will not detect:
  • Moving objects, including pedestrians, animals, or other vehicles.
  • Objects positioned low to the ground or well above the sensor height.
  • Narrow, pole-like objects.
  • Wedge-shaped or angled obstacles that may deflect sonar waves.
  • Obstacles located extremely close to the rear bumper (typically within approximately 1 ft [30 cm]).
  • Objects that appear suddenly within the sensor's path.
  • Thin materials, including ropes, wires, or chains, which do not provide a sufficient radar or sonar return.
• The RAB system may fail to register specific types of obstacles, including:
  • Objects positioned significantly above the ground level.
  • Obstacles that are offset from the direct path of the vehicle.
  • Materials with soft, spongy, or porous surfaces—such as deep snow, dense foliage, or foam padding—that absorb rather than reflect sonar waves.
• System performance may be degraded or fully inhibited under the following conditions:
  • If the rear sonar sensors are obscured by mud, dirt, ice, heavy snow, or other road debris.
  • If there is intense ambient noise in the immediate vicinity that overwhelms the sensors.
  • If the surface of an obstacle is positioned at an acute or diagonal angle relative to the rear of your Nissan Leaf, causing the sonar signal to bounce away.
• Conversely, the RAB system may trigger an unintended emergency stop in scenarios where no collision risk exists, such as:
  • When driving through tall, overgrown grass or brush surrounding the vehicle.
  • When maneuvering near large structures like walls, tunnel entrances, toll gates, or narrow parking garage entries.
  • When driving over significant road irregularities, such as deep potholes, sharp bumps, or raised manhole covers.
  • When passing through draped materials like hanging flags, heavy curtains, or plastic tarps.
  • When reversing near thick, compact piles of accumulated snow or ice.
  • When in close proximity to another vehicle that is also emitting ultrasonic sonar waves.
• Important: After the RAB automatic brake control has triggered once, it will not re-engage if you continue to approach the exact same obstacle. You must take full control of the vehicle.
• The automatic braking pressure applied by the RAB system is intended to be an emergency intervention and is only maintained for a brief period; you must depress the brake pedal yourself to ensure your Nissan Leaf remains safely stopped.

Because the automatic braking applied by the Rear Automatic Braking (RAB) system is temporary, you must immediately depress the brake pedal yourself to maintain vehicle control and keep the Nissan Leaf at a complete stop.

• The RAB system may experience reduced performance or fail to function as intended in the following driving scenarios:
• Operating the vehicle in adverse weather conditions, such as heavy rain, dense fog, or during snowstorms.
• Backing up on steep inclines or declines.
• When the vehicle's orientation is significantly altered, such as while driving over speed bumps, deep potholes, or uneven terrain.
• Navigating on slippery or low-traction road surfaces where tire grip is compromised.
• Performing tight maneuvers with the steering wheel turned to its full lock position.
• Driving while using tire snow chains, which can interfere with vehicle dynamics and sensor accuracy.
• Equipping the Nissan Leaf with wheels or tires that do not meet the manufacturer's original specifications.
• Operating the vehicle in extremely low ambient temperatures, where the brake system may be cold or less responsive immediately after startup.
• Reduced braking efficiency occurring after driving through standing water or immediately following a vehicle wash, as moisture can temporarily diminish friction.
• To ensure your safety and prevent the RAB system from initiating an unexpected or unnecessary emergency stop, you should manually turn the system OFF in the following circumstances:
  • Whenever the vehicle is being towed.
  • When the vehicle is being transported on a flatbed truck.
  • During testing or maintenance on a chassis dynamometer.
  • When driving over exceptionally rugged, uneven, or unpaved road surfaces.
  • When the Nissan Leaf is being used to tow a trailer or other object.
  • If the vehicle has been modified with aftermarket suspension components. Using non-genuine NISSAN parts can alter the vehicle's ride height or body angle, which may cause the sensors to misjudge the distance to obstacles.
  • If you have installed rear-mounted accessories, such as a bicycle rack, cargo carrier, or storage box that physically obstructs the rear bumper sonar sensors.
• Please be aware that elevated cabin noise—such as high-volume audio playback or driving with windows open—can easily mask the system’s audible alert chime, potentially leaving you unaware of a warning.
