When it comes to the maintenance of your Mercedes E-Class, understanding the location of all key components is crucial. Whether you’re dealing with an issue related to the cigarette lighter not functioning or you’re setting out to make replacements, locating the cigarette lighter fuse can save you time and effort. The cigarette lighter, also known as the power outlet, is an essential feature that allows you to charge devices while traveling. If it isn’t working correctly, it may simply be a blown fuse. Below, we explore where to find the cigarette lighter fuse location in your Mercedes E-Class.

Understanding the Fuse Box Layout

The fuse box in the Mercedes E-Class is strategically located to be accessible yet out of the way. Typically, in most models, there are two main fuse boxes: one located under the hood and the other inside the cabin.

Cabin Fuse Box

The cabin fuse box is commonly located on the side of the dashboard or near the driver’s side footwell. To access it, you may need to open a panel or remove a cover. The cigarette lighter fuse is often found here. When you find this panel, look for the fuse labeled specifically for the cigarette lighter or power outlet. It’s often in the range of 15A to 20A.

Under Hood Fuse Box

Another possible location for the cigarette lighter fuse is in the under-hood fuse box. This is generally situated near the battery, often on the passenger side. While it is less common for the cigarette lighter fuse to be here, checking this box can sometimes be necessary depending on your specific model year and trim.

Steps to Replace the Fuse

• Turn off your vehicle and remove the key from the ignition to ensure safety.
• Use your vehicle manual to locate the exact fuse box and fuse number for the cigarette lighter.



• Identify the fuse using the diagram or chart provided either in the fuse box cover or the vehicle’s manual.
• Once located, use a fuse puller or needle-nose pliers to remove the defective fuse.
• Replace it with a fuse of the same amp rating to avoid any electrical issues.
• After replacing, test the cigarette lighter to ensure it’s working properly.

Replacing a fuse can often resolve an issue with a non-functioning cigarette lighter, saving you from unnecessary costs at the mechanic.

Why Is It Important?

Knowing the location of your cigarette lighter fuse and understanding how to replace it is a valuable skill. It helps in maintaining the full functionality of your Mercedes E-Class’s electrical components. A faulty cigarette lighter can prevent you from charging phones or using other essential devices when on the road.

Common Issues Post Fuse Replacement

If your cigarette lighter still doesn’t work after fuse replacement, consider the following possibilities:

• The cigarette lighter socket itself might be faulty.
• There might be another electrical issue affecting its functionality.
• Your replacement fuse may have been incorrect or faulty; double-check the amp rating.

Frequently Asked Questions (FAQ)

Q1: Can I use any amp rated fuse as a replacement?

No, always use a fuse with the same amp rating as specified in the manual or fuse box cover to prevent electrical problems or hazards.

Q2: What happens if the fuse keeps blowing?

This might indicate an underlying electrical problem. It’s best to have your vehicle checked by a professional mechanic.

Q3: Is the cigarette lighter fuse different for every Mercedes model?

While the location can vary slightly, the fuse rating for a cigarette lighter is generally similar across Mercedes models. Always refer to your vehicle’s manual for precise information.

In conclusion, understanding the cigarette lighter fuse location is an essential aspect of owning a Mercedes E-Class. With this knowledge, you’re well-prepared to tackle small hiccups related to charging and electrical outlets in your vehicle.
