Nissan Pathfinder: Starting and driving - Rear Automatic Braking (RAB)

• Basic information
• RAB system operation
• RAB system limitations

Basic information Nissan Pathfinder 2022

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

• The RAB system is a supplemental aid to the driver. It is not a replacement for proper driving procedures.

  Always use the side and rear mirrors and turn and look in the direction you will move before and while backing up. Never rely solely on the RAB system.

  It is the driver's responsibility to stay alert, drive safely, and be in control of the vehicle at all times.

• There is a limitation to the RAB system capability. The RAB system is not effective in all situations.
• Inclement weather or ultrasonic sources such as an automatic car wash, a truck's compressed-air brakes or a pneumatic drill may affect the function of the system; this may include reduced performance or a false activation.

The RAB system can assist the driver when the vehicle is backing up and approaching objects directly behind the vehicle.

The RAB system detects obstacles behind the vehicle using the parking sensors 1 located on the rear bumper.

NOTE: You can temporarily cancel the sonar function and the RAB system in the vehicle.

RAB system operation Nissan Pathfinder SUV

For vehicles with the 7 inch (18 cm) display

1. RAB system warning light
2. RAB system warning indicator
3. Center display
4. Steering-wheel-mounted controls (left side)

When the shift lever is in the R (Reverse) position and the vehicle speed is less than approximately 9 mph (15 km/h), the RAB system operates.

If a risk of a collision with an obstacle is detected when your vehicle is backing up, the RAB system warning indicator will flash in the vehicle information display, a red frame will appear in the center display (for vehicles with the Intelligent Around View Monitor system), and the system will chime three times. The system will then automatically apply the brakes. After the automatic brake application, the driver must depress the brake pedal to maintain brake pressure.

For vehicles with the 12.3inch (31.2 cm) display

NOTE:

• The brake lights of the vehicle come on when braking is performed by the RAB system.
• When the brakes operate, a noise may be heard. This is not a malfunction.

Turning the RAB system on/off

For vehicles with the 7 inch (18 cm) display

Perform the following steps to turn the RAB system ON or OFF.

1. Press the button until "Settings" displays in the vehicle information display.

Use the scroll dial to select "Driver Assistance." Then press the OK button.

2. Select "Emergency Assist" and press the OK button.

3. Select "Rear Auto Braking" and press the OK button to turn the system on or off.

When the RAB system is turned off and when the vehicle is in the R (Reverse) position, the RAB system warning light illuminates.

NOTE: The RAB system will be automatically turned on when the engine is restarted.

RAB system limitations Nissan Pathfinder R53

WARNING 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 narrow tunnel, 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.
  • The vehicle is towing an object (if so equipped).
  • 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.)
  • If the vehicle is using an accessory like a bike rack, or cargo carrier that blocks the sensors.
• Excessive noise (e.g., audio system volume, an open vehicle window) will interfere with the chime sound, and it may not be heard.

System malfunction

If the RAB system malfunctions, it will be turned off automatically, the RAB system warning light will illuminate, and the "Malfunction: See Owner's Manual" warning message will appear in the vehicle information display.

Action to take

If the warning light illuminates, park the vehicle in a safe location, turn the engine off, and restart the engine. If the warning light continues to illuminate, have the RAB system checked. It is recommended that you visit a NISSAN dealer for this service.

NOTE: If the RAB system cannot be operated temporarily, the RAB system warning light blinks.

System maintenance

Observe the following items to ensure proper operation of the system:

• Always keep the parking sensors 1 clean.
• If the parking sensors are dirty, wipe them off with a soft cloth while being careful to not damage them.
• Do not subject the area around the parking sensors 1 to strong impact. Also, do not remove or disassemble the parking sensors. If the parking sensors and peripheral areas are deformed in an accident, etc., have the sensors checked. It is recommended that you visit a NISSAN dealer for this service.
• Do not install any stickers (including transparent stickers) or accessories on the parking sensors 1 and their surrounding areas. This may cause a malfunction or improper operation.
