Infiniti is the luxury vehicle division of Japanese automaker Nissan. Infiniti officially started selling vehicles on November 8, 1989 in North America. The marketing network for Infiniti-branded vehicles now includes over 230 dealers in over 15 countries.

The Infiniti marque was formally introduced to its homeland of Japan in 2013, with the first Japanese-market Infiniti vehicle to be a hybrid-powered variant of the Infiniti Q50 to go on sale in 2014, with gasoline-powered versions of the Q50 retaining the historic Nissan Skyline name. However, this does not mark the first introduction of the Infiniti brand to Japan, with the original Q45 being sold as the Nissan Infiniti Q45 in Japan from November 1989 until 1996.

Infiniti models have direct equivalents in the Japanese domestic market Nissan lineup. The Infiniti G as the Nissan Skyline sedan and coupe and previously the Nissan Primera, Infiniti M as the Nissan Fuga and previously the Nissan Leopard, Infiniti EX as the Nissan Skyline crossover, and Infiniti Q45 as the Nissan Cima. The Infiniti FX has no Nissan equivalent and is not sold in Japan. The Skyline and Cima were luxury vehicles in Japan in earlier forms, and were originally exclusive to Japanese Nissan dealership network called Nissan Prince Shop, then later called Nissan Red Stage until the Japanese dealership network was disbanded.

The Infiniti Publications website (http://www.Infiniti-TechInfo.com/) has been established to comply with the requirements of the Environmental Protection Agency's (EPA) regulation [Federal Register: June 8, 2001 (Volume 66, Number 111)]. This came in force during 2003 and requires that Automotive Manufacturers make available emission related service and repair information for online viewing along with information concerning training, special tools, and certain diagnostic and reprogramming aids.

The website is your source for Owners and Service information about your Infiniti vehicle. Service Publications are available for purchase as printed books or in electronic format on a Compact Disk (currently available for Windows only). This website only contains information for vehicles sold in the North American market.

The website also provides easy online access to a comprehensive library of Infiniti vehicle-related documentation. While some items, including Infiniti Owners Manuals, are available at no cost to you, other items require an online subscription. See the website for current subscription options.
