REAR AUTOMATIC BRAKING (RAB)

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 1O located on the rear bumper.

NOTE:
You can temporarily cancel the sonar function in the vehicle, but the RAB sys-tem will continue to operate. 

RAB SYSTEM OPERATION

 

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

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
Perform the following steps to turn the RAB system ON or OFF. For vehicles with the 7-inch (18 cm) display.

  • 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 Rear automatic braking warning light nissan malfunctions, it will be turned off automatically, the RAB system warning light will illuminate, and the “Mal-function: See Owner’s Manual” warning message will appear in the vehicle information display and a chime will sound.

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 1O 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 1O 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 1O and their surrounding areas. This may cause a malfunction or improper operation.

AUTOMATIC EMERGENCY BRAKING (AEB) WITH PEDESTRIAN DETECTION

WARNING
Failure to follow the warnings and instructions for proper use of the AEB with the Pedestrian Detection system could result in serious injury or death. The AEB with Pedestrian Detection system is a supplemental aid to the driver. It is not a replacement for the driver’s attention to traffic conditions or responsibility to drive safely. It cannot prevent accidents due to carelessness or dangerous driving techniques. The AEB with Pedestrian Detection system does not function in all driving, traffic, weather and road conditions. The AEB with Pedestrian Detection system can assist the driver when there is a risk of a forward collision with the vehicle ahead in the traveling lane or with a pedestrian ahead in the traveling lane.

The AEB with Pedestrian Detection system uses a radar sensor located on the front of the vehicle OB to measure the distance to the vehicle ahead in the same lane. For pedestrians, the AEB with Pedestrian Detection system uses a camera installed behind the windshield OA in addition to the radar sensor.

AEB WITH PEDESTRIAN DETECTION SYSTEM OPERATION

For vehicles with the 5 inch (13 cm) display

1. The vehicle ahead detection indicator
2. AEB with Pedestrian Detection emergency warning indicator
3. AEB with Pedestrian Detection system warning light
   The AEB system operates at speeds above approximately 3 mph (5 km/h). For the pedestrian detection function, the system operates at speeds between 6–37mph (10 – 60 km/h).
   If a risk of a forward collision is detected, the AEB with Pedestrian Detection system will first provide the warning to the driver by flashing the vehicle ahead detection indicator (yellow) in the vehicle information display and providing an audible alert. If the driver applies the brakes quickly and forcefully after the warning, and the AEB with Pedestrian Detection system detects that there is still the possibility of a forward collision, the system will automatically increase the braking force.

If the driver does not take action, the AEB with Pedestrian Detection system issues the second visual (2) (flashing) (red and white) and audible warning. If the driver releases the accelerator pedal, then the system applies partial braking. If the risk of a collision becomes imminent, the AEB with Pedestrian Detection system applies harder braking automatically. While the AEB with Pedestrian Detection system is operating, you may hear the sound of brake operation. This is normal and indicates that the AEB with Pedestrian Detection system is operating properly.

NOTE:
The vehicle’s brake lights come on when any braking is performed by the AEB with the Pedestrian Detection system. Depending on vehicle speed and distance to the vehicle or pedestrian ahead, as well as driving and roadway conditions, the sys-tem may help the driver avoid a forward collision or may help mitigate the consequences if a collision should be unavoidable. If the driver is handling the steering wheel, accelerating or braking, the AEB with Pedestrian Detection system will function later or will not function.

The rear automatic braking malfunction Nissan Altima will cease under the following conditions:

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

If the AEB with Pedestrian Detection sys-tem has stopped the vehicle, the vehicle will remain at a standstill for approximately 2 seconds before the brakes are released.

TURNING THE AEB WITH PEDESTRIAN DETECTION SYSTEM ON/OF
Perform the following steps to enable or disable the AEB with the Pedestrian Detection system. For vehicles with a 7-inch (18 cm) display.

1. Press the button until “Settings” displays in the vehicle information display. Use the button to select “Driver Assistance.” Then press the OK button.
2. Select “Emergency Brake” and press the OK button.
3. Select “Front” and press the OK button to turn the system on or off.
