In terms of passive safety, the Mercedes-Benz has always been a leader. The GL-Class is equipped with various airbags, including two-stage driver and front-passenger airbags and windowbags extending over all three rows of seats, whose protection zone covers virtually the entire area of the side windows. The sidebags and windowbags in the GL-Class feature a newly developed control technology: pressure sensors. If the door deforms in a side-on collision, the increase in air pressure between the body panels and the interior of the door is registered by the pressure sensors, assisting the control unit with deployment of the sidebags and windowbags.
