Nissan Murano 2015-2022 Owners Manual / Starting and driving / Rear Automatic Braking (RAB) (if so equipped) / RAB system limitations


Listed below are the system limitations for the RAB system. Failure to follow the warnings and instructions for proper use of the RAB system could result in serious injury or death.

  • When the vehicle approaches an obstacle while the accelerator or brake pedal is depressed, the function may not operate or the start of operation may be delayed. The RAB system may not operate or may not perform sufficiently due to vehicle conditions, driving conditions, the traffic environment, the weather, road surface conditions, etc. Do not wait for the system to operate. Operate the brake pedal by yourself as soon as necessary.
  • If it is necessary to override RAB operation, strongly press the accelerator pedal.
  • Always check your surroundings and turn to check what is behind you before and while backing up. The RAB system detects stationary objects behind the vehicle.The RAB system does not detect the following objects:
    • Moving objects
    • Low objects
    • Narrow objects
    • Wedge-shaped objects
    • Objects close to the bumper (less than approximately 1 ft [30 cm])
    • Objects that suddenly appear
    • Thin objects such as rope, wire, chain, etc.
  • The RAB system may not operate for the following obstacles:
    • Obstacles located high off the ground
    • Obstacles in a position offset from your vehicle
    • Obstacles, such as spongy materials or snow, that have soft outer surfaces and can easily absorb a sound wave
  • The RAB system may not operate in the following conditions:
    • There is rain, snow, ice, dirt, etc., attached to the sonar sensors.
    • A loud sound is heard in the area around the vehicle.
    • The surface of the obstacle is diagonal to the rear of the vehicle.
  • The RAB system may unintentionally operate in the following conditions:
    • There is overgrown grass in the area around the vehicle.
    • There is a structure (e.g., a wall, toll gate equipment, a narrowtunnel, a parking lot gate) near the side of the vehicle.
    • There are bumps, protrusions, or manhole covers on the road surface.
    • The vehicle drives through a draped flag or a curtain.
    • There is an accumulation of snow or ice behind the vehicle.
    • An ultrasonic wave source, such as another vehicle’s sonar, is near the vehicle.
  • Once the automatic brake control operates, it does not operate again if the vehicle approaches the same obstacle.
  • The automatic brake control can only operate for a short period of time. Therefore, the driver must depress the brake pedal.
  • In the following situations, the RAB system may not operate properly or may not function sufficiently:
    • The vehicle is driven in bad weather (rain, fog, snow, etc.).
    • The vehicle is driven on a steep hill.
    • The vehicle’s posture is changed (e.g., when driving over a bump).
    • The vehicle is driven on a slippery road.
    • The vehicle is turned sharply by turning the steering wheel fully.
    • Snow chains are used.
    • Wheels or tires other than NISSAN recommended are used.
    • The brakes are cold at low ambient temperatures or immediately after driving has started.
    • The braking force becomes poor due to wet brakes after driving through a puddle or washing the vehicle.
  • Turn the RAB system off in the following conditions to prevent the occurrence of an unexpected accident resulting from sudden system operation:
    • The vehicle is towed.
    • The vehicle is carried on a flatbed truck.
    • The vehicle is on the chassis dynamometer.
    • The vehicle drives on an uneven road surface.
    • Suspension parts other than those designated as Genuine NISSAN parts are used. (If the vehicle height or the vehicle body inclination is changed, the system may not detect an obstacle correctly.)
  • Excessive noise (e.g., audio system volume, an open vehicle window) will interfere with the chime sound, and it may not be heard.

    Nissan Murano. LATCH (Lower Anchors and Tethers for CHildren) system

    LATCH system lower anchor locations - bench seat

    Your vehicle is equipped with special anchor points that are used with LATCH system compatible child restraints. This system may also be referred to as the ISOFIX or ISOFIX compatible system. With this system, you do not have to use a vehicle seat belt to secure the child restraint unless the combined weight of the child and child restraint exceeds 65 lbs. (29.5 kg). If the combined weight of the child and child restraint is greater than 65 lbs. (29.5 kg), use the vehicle’s seat belt (not the lower anchors) to install the child restraint. Be sure to follow the child restraint manufacturer’s instructions for installation.
