Nissan Motor Co.'s new chief executive said Tuesday he will accept being fired if he fails to turn around Japan's second-biggest automaker, which is grappling with plunging sales in the aftermath of the scandal surrounding former Chairman Carlos Ghosn.

Addressing shareholders for the first time since taking over the top position in December, Makoto Uchida put his job on the line at a raucous meeting where he faced demands ranging from cuts to executive pay to offering a bounty to bring Ghosn back to Japan after he fled to Lebanon.

Nissan's worsening performance has heaped pressure on the 53-year-old Uchida, who had been the firm's China chief and is now its third CEO since September, to come up with aggressive steps to revive the company.
