Toyota is offering its newest advanced driver assistance system (ADAS) technology, called Toyota Safety Sense 3.0 (TSS 3.0), on the 2023 Toyota Corolla line, the OEM has announced.

The expansion of TSS 3.0 to the Corolla, traditionally one of the best-selling passenger car lines in the U.S., would seem to guarantee that many more body shops will be encountering this new technology. It has previously been offered only on Toyota’s first all-electric SUV, the bZ4X, and the flagship Crown sedan.

TSS 3.0 is being offered on the Corolla, Corolla Hybrid, Corolla Hatchback, Corolla Cross, and GR Corolla, and will continue to roll out on other models of the Toyota lineup.

According to a Toyota spokesperson, shops that are already familiar with the previous versions, TSS 2.5 and 2.5+, should not expect to see many changes.

“TSS 3.0 uses the same types of sensors as the other TSS generations in our current lineup, camera and radar. Both are enhanced over the other TSS generation and have expanded detection ranges,” Paul Hogard, a product communications senior analyst, told Repairer Driven News.

Hogard said the software “accommodates the enhanced sensors, which provides added functionality or capability for certain systems.” TSS 3.0-equipped vehicles will also have an over-the-air update capability, he said.

Calibration procedures are “essentially the same since these systems are supported by the same types of sensors, camera and radar,” he said.

TSS 3.0 includes enhanced versions of Toyota’s Pre-Collision System with Pedestrian Detection (PCS w/PD), Lane Departure Alert with Steering Assist (LDA w/SA), Dynamic Radar Cruise Control (DRCC), Lane Tracing Assist (LTA), Road Sign Assist (RSA), and Automatic High Beams (AHB).

New in this generation of TSS is the Emergency Driving Stop System (EDSS), a driver monitoring system. “If the EDSS determines the driver is not attentive and the driver does not respond to prompts to resume control of the vehicle, it can bring the vehicle to a stop under certain conditions,” Hogard said.

Also new is Proactive Driving Assist, available on certain TSS 3.0 vehicles. “Proactive Driving Assist provides gentle braking into curves or gentle braking and/or steering to help support driving tasks such as distance control between the vehicle and a preceding vehicle, pedestrian, or bicyclist,” he said.


Hogard described the enhanced capabilities of other features:

  • Pre-Collision System is capable of detecting motorcycles and laterally approaching vehicles, such as cross traffic at an intersection.
  • Lane Departure Alert can now use additional objects to define the road, such as guardrails.
  • Dynamic Radar Cruise Control is capable of detecting vehicles in adjacent lanes and offers an additional following distance setting.
  • Road Sign Assist detects additional sign types, such as warning signs.

Available as an option is the Blind Spot Monitor with Rear Cross-Traffic Alert system. In addition, the Corolla Sedan is available with Front and Rear Parking Assist with Automatic Braking. This provides a wider field of light and steers the low beams in the direction of the turn, based on steering angle and vehicle speed.

The 2023 Corolla Sedan models feature eight standard airbags and Toyota’s Star Safety System, which includes Enhanced Vehicle Stability Control, Traction Control, Electronic Brake-force Distribution, Brake Assist, Anti-lock Braking System, and Smart Stop Technology. All Corolla models come equipped with a backup camera.

All Corollas will also include 10-year trial subscriptions to Safety Connect, which provides roadside assistance, and Service Connect, which offers maintenance alerts and reminders.

Toyota also reports that the 2023 Corolla and Corolla Hybrid will have a refreshed look, with new front and rear fascias. On SE models, the look features a glossy black mesh-pattern lower grille and more sculptural front fascia, and a rear sport diffuser. The SE grades also get new 18-inch graphite-colored alloy wheels, and the LE replaces the 15-inch steel wheels with a 16-inch wheel. XLE features an all-new 10-spoke 16-in alloy wheel with a silver finish.

All Corolla Hybrid models and the sport models of the Corolla get new LED headlights.

Toyota said it intends to offer a special SE Infrared Edition later this year. The edition will feature bright red trim on the interior and exterior, and a choice of Ice Cap, Midnight Black Metallic, or new Underground exterior colors, and 18-inch Gloss Graphite-colored alloy wheels.

The essentially similar 2022 Toyota Corolla Hatchback earned a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (IIHS).
