Fuses and relays Infiniti FX35 / FX45 (S50), 2002 - 2009

The Infiniti FX crossover is the original premium urban all-wheel drive vehicle with off-road properties. In the US, the Infiniti FX was introduced back in 2002. All FX variants are based on a redesigned FM (Front Mid-ship) architecture platform, which features an engine positioned behind the front axle. The result is an optimal weight distribution between the front and rear axles. This factor affects the movement of the car during such basic maneuvers as entering and exiting corners, which is of great importance for a crossover.

In this article, we will take a detailed look at the fuse diagrams for the the Infiniti FX35 / FX45 1st generation (S50) 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 release. Here are the locations and photos of the fuse and relay blocks. The fuse responsible for the “Cigarette lighter” is highlighted in bold.
