Table of Contents
The electrical circuits of this Japanese premium sedan are protected by fuses and relays. These components are housed in distribution panels located in the engine compartment and the passenger compartment.
This guide provides detailed fuse box diagrams and location references for the first-generation (V36) Infiniti G35 / G37 / G25 / Q40 (2006–2015 model years). Component layout photos and distribution box locations are detailed below. The fuse assigned to the cigarette lighter is highlighted in bold text.
In the engine compartment
The engine compartment fuse blocks are located on the left side of the engine bay.
