Nissan Armada 2025-2026 Owner's Manual: System maintenance
Example
Basic information
The Nissan Armada RCTA system relies on two radar sensors (A) mounted near the rear bumper to detect approaching vehicles.
To ensure optimal performance of the Nissan Armada safety systems, always keep the radar sensor areas clean and unobstructed.
Environmental conditions such as water spray, fog, or condensation may temporarily reduce sensor performance.
Obstructions like ice, frost, dirt, or debris can also interfere with accurate detection.
Regularly inspect and clean the sensor areas on your Nissan Armada to maintain reliable system functionality.
Avoid placing stickers (including transparent materials), installing accessories, or applying additional paint near the radar sensors, as these modifications can degrade detection capability.
Do not strike, hit, or otherwise damage the sensor areas. If the rear bumper area of your Nissan Armada is damaged in a collision, it is strongly recommended to have it inspected by a NISSAN dealer.
Precautions on repairing the bumper
Special care must be taken when repairing the rear bumper of the Nissan Armada, as the radar sensors are integrated into this component.
The radar sensors operate by emitting signals and analyzing the reflections to detect objects and vehicles in the surrounding area.
WARNING
Improper repair methods—such as using incorrect materials, applying non-approved body fillers, or repainting without proper procedures—can weaken or block radar signals. This may prevent accurate detection and significantly increase the risk of accidents or injury.
If bumper repair is required, always consult an authorized NISSAN dealer to ensure that the Nissan Armada safety systems are properly restored and calibrated.
