Automatic high beams are included in all versions of TSS. This system reacts to oncoming vehicle headlights or taillights of vehicles ahead of you, automatically adjusting between low and high beams according to the situation.

The lane departure alert system warns you when you begin to leave your lane and detects the yellow or white lane markings on the road. On some models equipped with TSS-P, this alert may also include a steering assistance function, capable of applying slight corrections to the steering wheel.

Designed specifically for highway use, radar-based dynamic cruise control can automatically adjust your vehicle’s speed to maintain a predefined distance from the vehicle in front of you. This system operates within a speed range of approximately 40 to 180 km/h. On some Toyota models, the system can also perform vehicle-to-vehicle distance control down to a minimum speed of 0 km/h and resume operation after a stop.

The pre-collision system provides assistance to avoid collisions or mitigate their consequences in situations where a frontal collision is likely to occur. In some cases, the system can also assist the driver by automatically applying the brakes. The pre-collision system can also help detect pedestrians in certain situations.

In vehicles equipped with lane-keeping assist, this system works alongside radar-based dynamic cruise control to keep the vehicle centered in its lane when lane markings are visible on the road, thus preventing unintended deviations. Models equipped with TSS 3.0 now offer additional features such as lane tracing assist and emergency stop assist. The latter can bring the vehicle to a stop in certain conditions where the driver is inattentive and does not respond to warnings to regain control of the vehicle.
