Under what circumstances will the Automatic Collision Notification or Emergency Call Services activate in the 2025 QX55?

The Automatic Collision Notification or Emergency Call Services in the 2025 QX55 are designed to provide immediate assistance in the event of an emergency. The correct answer is the option that highlights the role of the SOS button. When the driver or a passenger presses the SOS button, it triggers a call to emergency services, alerting them to the situation and potentially providing important information about the vehicle's location and the nature of the incident.

This feature is crucial for providing timely responses in emergencies, ensuring that help can arrive as quickly as possible. It represents a proactive safety measure that allows occupants to seek immediate assistance when they are in distress, whether due to a collision or other emergencies.

The other options, while they might involve interactions with the vehicle, do not specifically activate the emergency communication features designed to assist in urgent situations. For instance, simply pressing a steering wheel button or opening a door does not indicate an emergency, and losing all power may disable many systems rather than activate the emergency call. Therefore, the correct functionality is directly related to the action of pressing the SOS button, which is specifically intended to initiate emergency services.
