In the UAE, for a GCC-spec Mercedes ML350, the cigarette lighter fuse is typically found in the engine compartment's fuse box near the battery, or under the dashboard on the driver's side—based on common owner reports and mechanic insights from Dubai workshops. RTA Dubai's vehicle maintenance guidelines note that fuses for auxiliary power outlets are often placed in accessible locations to simplify replacements, especially critical during peak traffic hours on routes like Sheikh Zayed Road where electrical failures can cause delays. MOI UAE emphasizes regular electrical system checks, particularly in summer temperatures above 40°C where prolonged air-conditioning use increases load on fuses. The fuse is usually rated 15A, equating to a 180W limit at 12V, but to prevent overloading, it's safer to cap device charging at 120W as per general practice. For context, other GCC-spec models like the Toyota Land Cruiser and Nissan Patrol have similar fuse placements in engine compartments, with ratings around 10-15A. From a cost perspective, replacing a blown fuse costs about 10 AED and takes minutes, but neglecting it can lead to pricier repairs—for example, overloading with high-power inverters during desert driving might blow the fuse, requiring a tow from remote dunes. I've seen this in my own experience: after 60,000 km of Dubai-Abu Dhabi highway drives, my ML350's fuse blew once from using a 150W device, and a quick check under the bonnet resolved it. Always verify fuse ratings in your owner's manual, as GCC-spec vehicles may differ from UK versions.
