Gentex Supplying Auto-Dimming Mirrors for Toyota Mark X

ZEELAND, Mich., Nov. 17, 2004 -- Gentex Corporation , the leading supplier of automatic-dimming mirrors to the worldwide automotive industry, has begun shipping interior automatic-dimming mirrors for the 2005 Mark X, Toyota's mid-size luxury sedan. The vehicle is the successor to the Mark II, one of the most popular and best-selling vehicles in Japan.

Gentex auto-dimming mirrors are active, crash-avoidance safety features. Rearview mirror glare can hinder the driver's forward vision, which in turn slows driver reaction time to potential road hazards and increases vehicle stopping distances. Auto-dimming mirrors automatically darken to reduce glare from the headlamps of vehicles approaching from the rear. The brighter the glare, the darker the mirrors become, making nighttime driving safer. Interior and exterior auto-dimming mirrors are available on a wide variety of vehicles around the world.

An interior automatic-dimming mirror is a standard feature on the Mark X 300G, 300G Premium, 300G S-package and 250G L-package trim levels.

"This program is landmark business for Gentex," stated Garth Deur, Gentex executive vice president. "The Mark X represents Toyota's most popular passenger car lineup in Japan. It's definitely a benchmark vehicle for the domestic Japan market, and we believe that the debut of auto-dimming mirror technology on the Mark X will open up many new opportunities for Gentex."
