SummarySome 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-definition 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 the 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.

SummaryFlash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the GTS+ ECU flash reprogramming process.

SummaryThe condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
