What Is a Mercedes Benz Fuse Chart?
A fuse chart, also known as a fuse diagram or fuse layout, is a visual representation that
details the location, function, and specifications of each fuse within a Mercedes Benz
vehicle. It acts as a map that helps you quickly identify which fuse controls specific
electrical components, such as headlights, radio, power windows, or airbags. The fuse
chart is typically found in the vehicle’s owner’s manual, under the fuse box cover, or as a
digital resource online. It provides crucial information such as: - Fuse number or position -
Fuse amperage rating - Circuit or component protected - Location of each fuse within the
fuse box Understanding the fuse chart is critical for diagnosing electrical problems and
replacing blown fuses safely and correctly.
Types of Fuses in Mercedes Benz Vehicles
Mercedes Benz vehicles utilize various types of fuses to protect electrical circuits:
Blade Fuses
- Most common in modern Mercedes Benz models - Flat, rectangular shape with two metal
prongs - Color-coded based on amperage rating (e.g., pink for 30A, blue for 15A)
Mini Fuses
- Smaller than standard blade fuses - Used in compact fuse boxes or circuits with limited
space
Micro Fuses
- Even smaller than mini fuses - Found in more recent models with advanced electronic
systems

High-Amp Fuses
- For high-current circuits like the starter or main power supply - Usually cylindrical or
cartridge style Knowing the type of fuse used is essential when replacing blown fuses to
ensure compatibility and safety.
Locating the Fuse Box in Mercedes Benz Vehicles
Mercedes Benz models typically have multiple fuse boxes located in different areas:
Main Fuse Box
- Usually found under the hood or engine compartment - Contains primary fuses for
engine and major electrical systems
Passenger Compartment Fuse Box
- Located inside the cabin, often near the dashboard or glove compartment - Contains
fuses for interior electronics, lighting, and accessories
Additional Fuse Boxes
- Some models include trunk or rear fuse boxes for auxiliary systems Refer to your
owner’s manual for exact locations specific to your model. Proper identification of fuse
box locations is the first step in troubleshooting.
How to Read a Mercedes Benz Fuse Chart
Reading the fuse chart accurately is critical for effective troubleshooting. Here’s a step-by-
step guide:
Identify the Fuse Number or Location: Each fuse is assigned a number or1.
position within the fuse box, often labeled on the fuse box cover.
Check the Amp Rating: The fuse’s amperage rating indicates the maximum2.
current it can handle before blowing. This is usually printed on the fuse itself and
shown in the chart.
Determine the Protected Circuit or Component: The chart will specify what3.
electrical component or system each fuse protects, such as the radio, headlights, or
ABS system.
Match the Color Code: The fuse color corresponds to its amperage (e.g., pink for4.
30A). Verify that the replacement fuse matches the rated color and amp rating.
Inspect the Fuse: If a fuse is blown, it will appear broken or burnt. Always replace5.
with a fuse of the same rating and type.
