Toyota Upgrades Features and Increases Auto-Dimming Mirror Availability on 2006 Sienna

ZEELAND, Mich., Nov. 29, 2005 -- Gentex Corporation, the leading supplier of automatic-dimming rearview mirrors to the worldwide automotive industry, today announced that it has begun shipping a three- mirror, automatic-dimming system for the 2006 Toyota Sienna.

Gentex 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.

The three-mirror system is standard on the Sienna Limited, and includes a base interior auto-dimming mirror as well as driver- and passenger-side exterior auto-dimming mirrors with integrated through-the-glass turn signals. These features are also available in an option package on the XLE, and as accessories on the CE and LE.

The turn signals in the exterior auto-dimming mirrors consist of an arrow- shaped array of LEDs aimed at the vehicle's blind spots, which serve to warn other drivers of impending turns and lane changes.

The Sienna is the second Toyota vehicle following the Avalon to offer a three-mirror, auto-dimming system as standard on its upper trim level.

"A key aspect of our continued growth is working with current customers to add features to existing mirror programs," said Gentex Executive Vice President Garth Deur. "The addition of the passenger-side exterior mirror and turn signal feature to the Sienna exemplifies Toyota's leadership in adding safety and technology enhancements to their vehicles."

Founded in 1974, Gentex Corporation is an international company that provides high-quality products to the worldwide automotive industry and North American fire protection market. Based in Zeeland, Michigan, the Company develops, manufactures and markets interior and exterior automatic-dimming automotive rearview mirrors that utilize proprietary electrochromic technology to dim in proportion to the amount of headlight glare from trailing vehicle headlamps. Many of the mirrors are sold with advanced electronic features, and approximately 95 percent of the Company's revenues are derived from the sales of auto-dimming mirrors to nearly every major automaker in the world.
