Toyota Safety Sense is standard across most of the new Toyota lineup and ensures that you and your passengers arrive at your destination safely. Toyota Safety Sense helps you pay attention when you forget.

Toyota Safety Sense, or TSS, is a suite of active safety technologies and advanced driver assistance systems designed to help address three key areas of accident protection: preventing or mitigating frontal collisions, keeping vehicles within their lane, and enhancing road safety during nighttime driving. TSS 2.5 and 2.5+ build on the previous TSS 2.0 suite by enhancing the functionalities of its six features, further utilizing a high-resolution camera and millimeter-wave radar to help keep occupants safe.

The six features of the Toyota Safety Sense suite are a Pre-Collision System, Lane Departure Alert with Steering Assist, Automatic High Beams, Lane Tracing Assist, Dynamic Radar Cruise Control, and Road Sign Assist.

The Pre-Collision System is designed to detect a vehicle or a pedestrian in either
daytime or low-light situations, as well as daytime detection of a bicyclist. When a potential hazard is detected, it may provide audible and visual alerts, and automatic braking in
certain conditions. TSS 2.5 and 2.5+ take it a step further with two additional functionalities: intersection support and emergency steering assist.

Lane Departure Alert works by detecting visible white/yellow lane markings or the road’s edge at speeds above 32 mph. It is designed to issue an audio and visual alert, as well as steering wheel vibrations on select vehicles, if an inadvertent lane departure is detected. If the driver does not take corrective action, the steering assist function is designed to provide gentle corrective steering.

Automatic High Beams is a safety system designed to help the driver see more clearly at night, while also reducing glare for other drivers. When activated, it is designed to help detect the headlights of oncoming vehicles and taillights of preceding vehicles, and automatically toggle between high and low beams as needed.

Lane Tracing Assist operates automatically when both Full-Speed Range Dynamic Radar Cruise Control and Lane Departure Alert are active. It is designed to help keep the vehicle centered in its marked lane and preemptively avoid unintended lane departures while cruising. It monitors lane markings, as well as the path of the vehicle ahead, if needed and is designed to automatically make constant steering inputs to help keep the vehicle centered in its lane.

Dynamic Radar Cruise Control is designed to help detect slower preceding vehicles and automatically adjust the vehicle’s speed to help maintain a preset distance behind the vehicle ahead. Select vehicles have Full-Speed Range Dynamic Radar Cruise Control, which is designed to enable low-speed following and stopping, in addition to the Dynamic Cruise Control’s speed matching, acceleration and deceleration. For TSS 2.5+, Dynamic Radar Cruise Control benefits from curve speed management, which uses the vehicle’s camera and yaw sensors to sense curves and reduce speed as the vehicle enters the turn, and then returns to the set speed upon exiting the curve.

Road Sign Assist is designed to read certain traffic signs and display them on the vehicle’s multi-information display in the gauge cluster. This helps provide the driver with additional awareness of posted road signs. The system can recognize speed limit, stop, yield, and do not enter signs. This provides the driver with additional awareness of posted road signs. In some cases, the system may also provide alerts if the speed exceeds the posted limit or if a stop sign is ignored.
