Toyota Motor Corp has agreed to spend $1.1 billion to settle sweeping U.S. class-action litigation over claims that millions of its vehicles accelerate unintentionally, as the Japanese automaker seeks to move past the biggest safety crisis in its history. Shares of Toyota rose nearly 3 percent in Tokyo following the news, with some investors saying the settlement removed one uncertainty for the company and looked manageable given its improving sales outlook and a weaker yen. The proposed settlement will compensate customers for economic losses related to possible safety defects in Toyota vehicles, covering most of the litigation involving unintended acceleration, although it does not cover claims for wrongful death or injuries.
