The Toyota Isis is a seven-seat large MPV manufactured by Kanto Auto Works under contract for Japanese automaker Toyota. It is sold only in Japan and was launched in September 2004. It features sliding doors and is available with either front or four-wheel drive and straight-4 1.8 and 2.0-litre gasoline engines. It competes in Japan with the Honda Stream and the Nissan Lafesta.The Isis uses a unique approach to the sliding doors in that the front passenger door and the rear passenger sliding door interlock together when closed, instead of having a door jamb that the doors attach to. Toyota calls this on the Japanese Wikipedia article "Panoramic Door". This door system is used only on the passenger side. The doors on the drivers side attach with a conventional door jamb. The front passenger seat can be folded flat upon itself and then tilted forward to further provide passenger access. The doors also interlock into the top and bottom door openings so that both doors can be opened independently of each other. This door feature was first used by Toyota on the Toyota Raum. This door approach is also used on the USA-spec 2000-2006 Toyota Tundra Extra Cab. This type of door was first used on the Nissan Prairie in 1981.For model year 2007 on Japanese models only, G-BOOK, a subscription telematics service, is offered as an option.The vehicle was named for Isis, a goddess in Ancient Egyptian religious beliefs, whose worship spread throughout the Greco-Roman world. She was worshipped as the ideal mother and wife, matron of nature and magic; friend of slaves, sinners, artisans, the downtrodden, as well as listening to the prayers of the wealthy, maidens, aristocrats and rulers. Isis is the Goddess of motherhood and fertility.
