Nissan X-Trail e-POWER 2023 Owners Manual
8.16.7.1. Precautions on repairing the bumper
When repairing the bumper, take caution because the radar sensors are installed on the bumper.
The radar sensor detects objects by emitting a radar signal and then measuring its reflection.
If an improper repair is performed on the bumper (for example, application of putty made from different materials, repaint, etc.) the radar signal could be weakened or prevented from functioning properly. This may cause the radar sensor not to detect objects correctly. Improper repair may result in serious personal injury. If it is necessary to repair the bumper, it is recommended you visit a NISSAN dealer or qualified workshop for this service.
