What happens when a driver activates the turn signal and the 2025 QX55's Blind Spot Warning (BSW) detects a vehicle in the next lane?

When a driver activates the turn signal in the 2025 QX55 and the Blind Spot Warning (BSW) system detects a vehicle in the adjacent lane, the system responds with an important safety feature designed to alert the driver. Specifically, an indicator light will flash in the side mirror corresponding to the side of the detected vehicle, and an audible tone will sound. This dual alert is crucial because it helps ensure the driver is aware of the potential hazard before changing lanes, enhancing safety and reducing the risk of collisions.

The primary purpose of this feature is to provide immediate, clear signals to the driver, emphasizing the presence of another vehicle that may not be visible in the blind spot. Thus, the correct response is that both visual and auditory alerts are used together to convey this warning.

In contrast, the other options do not accurately describe the BSW system's functionality in this scenario. For instance, the turn signal being activated alone would not provide the necessary safety reminders about nearby vehicles. An automatic adjustment of the rearview mirror or a message appearing on the dashboard would not provide the same immediate level of awareness regarding vehicular proximity as the simultaneous auditory and visual alerts.
