The vehicles being recalled were produced between January 2004 and May 2006 and sold in Europe, Africa and other regions. No accidents were reported due to the faulty switch, a Toyota spokesperson said.
With the faulty switch, the front seat airbag may open even as if the airbag switch is turned off.
The company declined to provide the cost for the latest recall.
Recalls by Japan's biggest car maker by sales volume have been increasing recently due to the rapid rise in its production volume to meet its growing vehicle sales.
Toyota, which is known for the quality of its vehicles, has said that improving quality control is one of the key issues that it is working on.
