Production of the third-generation Hyundai Elantra began in 2000. Starting in 2001, North American market models came standard with airbags, air conditioning, central locking, power windows, and power steering. The vehicle underwent a mid-cycle facelift in 2003. This guide provides detailed fuse and relay box diagrams, panel locations, and circuit assignments for the Hyundai Elantra (third generation; XD chassis) covering the 2000, 2001, 2002, 2003, 2004, 2005, and 2006 model years.
Below you will find location diagrams and photos of the power distribution centers. Circuits for the “Cigarette Lighter” and “Fuel Pump” are highlighted in bold.
