KIA Optima (JF; 2016-2019..) fuses and relays

 

In this article, we consider the fourth-generation KIA Optima (JF), available from 2016 to the present. Here you will find fuse box diagrams of KIA Optima 2016, 2017, 2018 and 2019, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.

Fuse Layout KIA Optima 2016-2019…


Cigar lighter (power outlet) fuses in the KIA Optima are located in the Instrument panel fuse box (see fuse “POWER OUTLET” (Front Power Outlet #1, Front Cigarette Lighter & Power Outlet #2)), and in the Engine compartment fuse box (fuses “POWER OUTLET 1” (Power Outlet Relay), “POWER OUTLET 3” (Rear Power Outlet) and “POWER OUTLET 2” (Front Power Outlet #1)).
