Nissan Altima (L34) 2019-2024 Owners Manual: RCTA system limitations

WARNING

Listed below are the system limitations for the RCTA system. Failure to operate the vehicle in accordance with these system limitations could result in serious injury or death.

• Always check surroundings and turn to check what is behind you before backing up. The radar sensors detect approaching (moving) vehicles. The radar sensors cannot detect every object such as:
  • Pedestrians, bicycles, motorcycles, animals or child-operated toy vehicles
  • A vehicle that is passing at speeds greater than approximately 19 mph (30 km/h)
  • A vehicle that is passing at speeds lower than approximately 5 mph (8 km/h)
• The radar sensors may not detect approaching vehicles in certain situations:
  • Illustration A : When a vehicle parked next to you obstructs the beam of the radar sensor.
  • Illustration B : When the vehicle is parked in an angled parking space.
  • Illustration C : When the vehicle is parked on inclined ground.
  • Illustration D : When an approaching vehicle turns into your vehicle's parking lot aisle.
  • Illustration E : When the angle formed by your vehicle and approaching vehicle is small.
• The following conditions may reduce the ability of the radar to detect other vehicles:
  • Severe weather
  • Road spray
  • Ice/frost/snow/dirt build-up on the vehicle
• Do not attach stickers (including transparent material), install accessories or apply additional paint near the radar sensors. These conditions may reduce the ability of the radar to detect other vehicles.
• Excessive noise (e.g., audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard.

NOTE:

In the case of several vehicles approaching in a row (Illustration 1) or in the opposite direction (Illustration 2), a chime may not be sounded by the RCTA system after the first vehicle passes the sensors.
