The Toyota Sienna has long been synonymous with family-friendly innovation and safety. For the 2025 model year, Toyota elevates its commitment to passenger well-being by introducing the standard Advanced Rear Seat Reminder across all Sienna grades in the U.S. This groundbreaking technology, a global first for Toyota, utilizes millimeter-wave radar to detect movement within the vehicle after the driver has exited, adding an extra layer of protection for families on the go.
This innovative system goes beyond conventional reminders, employing sophisticated technology to ensure no one is unintentionally left behind. Let’s delve into how the Advanced Rear Seat Reminder in the 2025 Toyota Sienna sets a new benchmark in automotive safety.
Advanced Millimeter-Wave Radar: Precision Occupant Detection in the Toyota Sienna
At the heart of the Advanced Rear Seat Reminder is a high-resolution 60GHz band radar sensor, strategically positioned above the Sienna’s headliner. This advanced sensor actively scans a defined area encompassing the second and third rows of seats, meticulously detecting even subtle movements. Unlike traditional ultrasonic systems, this millimeter-wave radar boasts superior precision and the unique ability to sense movement even under objects, such as a blanket. This is particularly advantageous in scenarios where a child might be sleeping or obscured from direct view. Furthermore, the radar technology excels in low-light conditions, offering a significant advantage over camera-based monitoring systems, ensuring reliable occupant detection regardless of lighting.

The system activates once the ignition is turned off, the driver’s door is opened and closed, and the vehicle is locked. If movement is detected within the scanned area after these steps, the Advanced Rear Seat Reminder initiates a series of escalating alerts, starting with flashing hazard lights and a door lock chime.
Escalating Alerts: Ensuring Awareness and Action for Toyota Sienna Drivers
The 2025 Toyota Sienna’s Advanced Rear Seat Reminder employs a multi-tiered alert system designed to maximize driver awareness. Approximately 90 seconds after the initial chime and hazard light warning, should the system continue to detect movement, the horn will sound as a more prominent escalation. These initial warnings are built directly into the vehicle’s hardware and do not require a Toyota app subscription to function, ensuring a base level of safety for all Toyota Sienna owners.

For Toyota Sienna drivers seeking an even greater level of connectivity and reassurance, the system offers further escalation through the Toyota app and Safety Connect subscription. If a driver is registered for Safety Connect and has opted into Advanced Rear Seat Reminder notifications via the Toyota app, approximately four minutes after the horn escalation begins, the system can send a push notification through the app and an SMS text message to the registered mobile number. As a final measure, after an additional two minutes, the saved contact number will receive an automated phone call, providing multiple layers of communication to ensure awareness. Notably, even if the vehicle is left unlocked, Safety Connect subscribers who have opted in will still receive a push notification and SMS message to their registered devices should movement be detected.
Peace of Mind and Enhanced Family Security with Toyota Sienna
The development of the Advanced Rear Seat Reminder is a testament to Toyota’s dedication to innovation driven by real-world needs. Born from an internal technology competition at Toyota Motor North America, this feature represents a global collaboration involving numerous software, hardware, R&D, and supplier companies within and outside of Toyota. The result is a sophisticated system backed by over 40 patent applications, underscoring Toyota’s commitment to leading the way in automotive safety technology.
