In this article we take a look at the sixth generation Hyundai Elantra (AD), available from 2017 to the present. Here you will find the 2017, 2018, 2019 and 2020 Hyundai Elantra fuse box diagrams, get information on the location of the fuse boxes in the car and learn about the assignment of each fuse (fuse layout) and relay.
The fuses for the cigarette lighter (socket) are located in the engine compartment fuse box (see fuses “POWER OUTLET 3” (cigarette lighter), “POWER OUTLET 2” (front socket) and “POWER OUTLET 1” (socket relay)).
