# Over\-the\-air update T\-SB\-0057\-24

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Some 2022 model year Mirai vehicles are equipped with Toyota Teammate Advanced Drive. This system provides driving support through automated steering, acceleration, and braking under specific operating conditions within controlled access highways. Toyota Teammate Advanced Drive utilizes an array of sensors and cameras, high definitions maps, and the vehicle navigation system to provide hands\-free \(SAE level: 2\) driving assistance for engaged drivers. Updates to enhance Toyota Teammate Advanced Drive operation or to add features/functions are delivered to the vehicle directly through the Toyota Teammate multimedia head unit \(earlier than version 5.00\). The updates include the following: •Updates the Advanced Drive messages and displays. •Reduces the frequency of prompts to hold the steering wheel in certain circumstances \(e.g., facial recognition impact reduced when wearing a medical mask\). •Increases scenarios where lane change assist can be used. •Adjusts the speed to help avoid blind spots of other vehicles in adjacent lanes. •Enhances peripheral recognition using LiDARs. •Reduces lane change assist activation when standard construction cones or barrels are detected. •Alerts driver to nearby vehicles at certain highway entrance merging areas during low\-speed driving. •Alerts driver when approaching a much slower vehicle ahead. •Increases the maximum Advanced Drive set speed to 85 mph. The release notes text below will be displayed to the customer: “Updates the Advanced Drive messages and displays, reduces the frequency of prompts to hold the steering wheel in certain circumstances \(e.g., facial recognition impact reduced when wearing a medical mask\), increases scenarios where lane change assist can be used, adjusts the speed to help avoid blind spots of other vehicles in adjacent lanes, enhances peripheral recognition using LiDARs, reduces lane change assist activation when standard construction cones or barrels are detected, alerts driver to nearby vehicles at certain highway entrance merging areas during low\-speed driving, alerts driver when approaching a much slower vehicle ahead, increases the maximum Advanced Drive set speed to 85 mph.”
