These are the safety features you can expect in the new Prius and Prius Prime.

Most of the features are the same but the Prius Prime comes with more additional features because it's equipped with front corner radar sensors and a driver monitor camera. The additional features it comes with are: Lane Change Assist, Front Cross Traffic Alert, Advanced Park and, a first among the Toyota line-up, Traffic Jam Assist.

2023 Prius:

Safety

For 2023, Prius will come standard with the latest Toyota Safety Sense generation, TSS 3.0. This suite of active safety systems includes the existing feature set available on the prior generation Prius but includes some additional enhancements and capabilities. This suite of safety features includes:

• Pre-Collision System with Pedestrian Detection
• Lane Departure Alert with Steering Assist
• Full-Speed Range Dynamic Radar Cruise Control
• Lane Tracing Assist
• Road Sign Assist
• Automatic High Beams
• Proactive Driving Assist

Proactive Driving Assist is new to Prius and the Toyota Safety Sense package. When system operating conditions are met, using the vehicle’s camera and radar, this system provides gentle braking into curves or gentle braking and/or steering to help support driving tasks such as distance control between a preceding vehicle, pedestrian or bicyclist. Proactive Driving Assist is not a substitute for the Pre-Collision System and operates in different circumstances.

The Toyota Safety Sense feature from the prior generation Prius has been enhanced for TSS 3.0:

• The Pre-Collision System with Pedestrian Detection has enhanced detection capabilities thanks to new system sensors. It receives enhanced intersection support with improved detection capability in certain circumstances. It also adds the capability to detect motorcyclists, in addition to bicyclists and pedestrians.
• Lane Departure Alert with Steering Assist has enhanced lane recognition that includes detection of certain 3D objects, like guardrails, that may be used to help define the lane.
• Full-Speed Range Dynamic Radar Cruise Control adds a fourth following distance setting, from the previously available three. Enhanced vehicle detection allows for the ability to detect more than one preceding vehicle, as well as vehicles in adjacent lanes. This helps the system to provide smoother, more natural speed adjustments, especially when the driver changes lanes.
• Like Lane Departure Alert, lane recognition is enhanced for Lane Tracing Assist. This system now also helps provide more space between vehicles being passed in adjacent lanes. It works by offsetting the vehicles’ driving path with minor steering adjustments while keeping the vehicle within its lane.
• An Emergency Driving Stop System has been added to Lane Tracing Assist. It’s designed to monitor the driver’s inputs, such as steering operation, to determine if they’re inattentive or non-responsive, such as during a medical emergency. This feature can bring the vehicle to a stop if the driver doesn’t respond to alerts to take control.
• Road Sign Assist gets expanded sign detection capabilities that now include certain intersection signs and warning signs, like pedestrian crossings.

Prius Prime – Upgraded Convenience

Prius Prime will also come standard with some additional features made possible by the equipped front corner radar sensors and a driver monitor camera. These features include Lane Change Assist, Front Cross Traffic Alert, Advanced Park and, a first among the Toyota line-up, Traffic Jam Assist.

Lane Change Assist works in collaboration with Lane Tracing Assist, meaning it also only operates when DRCC is activated. When a driver partially engages the turn signal, the system sensors monitor to confirm there are no vehicles in the path of the lane change, and then provides steering support into the new lane with the driver’s hands on the steering wheel.

Front Cross Traffic Alert uses the front corner radar sensors to detect vehicles approaching from the side in situations such as when stopped at an intersection. Arrows are displayed to warn the driver, and if the driver attempts to proceed when there’s cross traffic, the vehicle provides an audible alert and warning on the MID.

Advanced Park executes the necessary steering and brake controls to navigate the vehicle into a selected parking space. Advanced Park is capable of parallel parking, backing into a perpendicular parking space, and can assist in exiting a parking space, all hands-free under the driver’s supervision.

Traffic Jam Assist is a first to Toyota and Prius Prime and can help take some of the stress out of the low-speed, stop-and-go driving in a traffic jam. When driving on a highway with DRCC and LTA activated, if the system sensors detect traffic is slowing, and if operating conditions are met, this system will assist by providing acceleration, braking and hands-free steering control under active supervision of the driver. This system is designed to operate only under speeds of approximately 25 miles per hour, and the driver monitor camera must confirm the driver has their eyes on the road to allow for hands-free operation. If operating conditions are no longer met, or if the speed of traffic increases beyond 25 miles per hour, the system will prompt the driver to take control of the vehicle.
