Mercedes-Benz E-CLASS SEDAN 2023 Electrical Fuses

The Mercedes-Benz E-Class Sedan 2023 is a high-end vehicle that features a range of electrical components that require protection against electrical faults and short circuits. The car has a fuse box that houses its electrical fuses, which safeguard various electrical components against electrical surges and other forms of electrical damage. The fuse box is conveniently located in the engine compartment and is easily accessible for maintenance purposes. The fuses are colour-coded based on their amperage rating and are designed to blow when the electrical current exceeds their rated amperage, thereby preventing damage to the electrical components. The Mercedes-Benz E-Class Sedan 2023 has several advanced electrical components, including the COMAND infotainment system, the digital instrument cluster, and the advanced driver assistance systems. To ensure that these systems operate reliably and safely, it is crucial to maintain the car’s electrical fuses and replace any blown fuses immediately.  This guide offers responses to frequently asked questions about the Mercedes-Benz E-Class Sedan 2023 electrical fuses, providing details on the fuse box’s location, the different types of fuses used, and how to identify and replace blown fuses.

Electrical Fuses

Notes on elect6rical fuses

WARNING
Risk of accident and injury due to overloaded lines

If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric line could be overloaded.
This could result in a fire.

• Always replace faulty fuses with specified new fuses containing the correct amperage.

NOTE
Damage due to incorrect fuses Using incorrect fuses can result in damage to electrical components or systems or their functions being considerably restricted.

• Use only fuses approved for Mercedes-Benz with the respective specified fuse rating.

Blown fuses must be replaced with fuses of the same rating, which you can recognize by the colour and the label. The fuse ratings and further information to be observed can be found in the fuse assignment diagram. Fuse assignment diagram: on the fuse box in the trunk.

NOTE
Damage or malfunctions caused by moisture Moisture may cause damage to the electrical system or cause it to malfunction.

• When the fuse box is open, make sure that no moisture can enter the fuse box.
• When closing the fuse box, make sure that the seal of the lid is positioned correctly on the fuse box

If a newly inserted fuse also blows, have the cause traced and rectified at a qualified specialist workshop.

Ensure the following before replacing a fuse:

• The vehicle is secured against rolling away. R All electrical consumers are switched off.
• The vehicle is switched off.

The electrical fuses are located in various fuse boxes:

• Fuse box in the engine compartment on the driver’s side
• Fuse box on the driver’s side of the cockpit
• Fuse box in the front passenger footwell
• Fuse box in the trunk on the right-hand side of the vehicle, when viewed in the direction of travel

Opening and closing the fuse box in the engine compartment

• A dry cloth and a screwdriver are available. Observe the notes on electrical fuses.

Opening
Risk of injury from using the windshield wipers when the hood is open If the windshield wipers start moving when the hood is open, you could be trapped by the wiper linkage.

• Always switch off the windshield wipers and the vehicle first if you need to open the hood.

• Open the hood.
• Turn clips 2 on cover 1 a quarter-turn to counter-clockwise.
• Pull cover 1 up.

• Remove any existing moisture from the fuse box using a dry cloth.
• Loosen screws 4 and remove fuse box lid 3 from the top.

Closing

• Check whether the seal is positioned correctly in lid 3.
• Insert lid 3 into the bracket at the rear of the fuse box.
• Fold down lid 3 of the fuse box and tighten screws 4.
• Insert cover 1 on both sides.
• Turn clips 2 on cover 1 a quarter-turn clockwise.
• Close the hood.

Opening and closing the fuse box in the cockpit

• R Observe the notes on electrical fuses.

The fuse box is on the driver’s side on the side of the cockpit under a cover.

• Mercedes-Benz recommends you have the Opening and closing the fuse box in the front passenger footwell

Observe the notes on electrical fuses.

• To open: open cover 1 in the direction of the arrow and remove it.
•  To close: reinsert cover 1.

Opening and closing the fuse box in the trunk

Observe the notes on electrical fuses.

• Fold cover 1 down in the direction of the arrow.
  The fuse assignment diagram is in a recess on the side of the fuse box.

Notes on noise or unusual handling characteristics
Make sure there are no vibrations, noises or unusual handling characteristics when the vehicle is in motion. This may indicate that the wheels or tires are damaged. Hidden tire damage could also be causing the unusual handling characteristics. If you suspect that a tire is defective, reduce your speed immediately and have the tires and wheels checked at a qualified specialist workshop.

Notes on regularly inspecting wheels and tires
Risk of injury through damaged tires Damaged tires can cause tire pressure loss.

• Check the tires regularly for signs of damage and replace any damaged tires immediately.

WARNING
Risk of hydroplaning due to insufficient tire tread Insufficient tire tread will result in reduced tire grip. In heavy rain or slush the risk of hydroplaning is increased, in particular where speed is not adapted to suit the conditions.

• Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires.

Minimum tread depth for:

• Summer tires: â in (3 mm)
• M+S tires: ãin (4 mm)
• For safety reasons, replace the tires before the legally prescribed limit for the minimum tread depth is reached.

Carry out the following checks on all wheels regularly, at least once a month or as required, for example, before a long journey or driving off-road:

• Check the tire pressure.
• Visually inspect wheels and tires for damage. R Check the valve caps.
• Visual check of the tire tread depth and the tire contact surface across the entire width.

The minimum tread depth for summer tires is â in (3 mm) and for winter tires ã in (4 mm).

Six marks 1 shows where the bar indicators (arrow) are integrated into the tire tread. They are visible once a tire tread depth of approximately á in (1.6 mm) has been reached.

Notes on Snow Chains
Risk of accident due to incorrectly installed snow chains. If you have installed snow chains on the front wheels, they may drag against the vehicle body or chassis components.

• Never install snow chains on the front wheels.
• Only install snow chains on the rear wheels in pairs.

NOTE
Damage to components of the vehicle body or chassis due to mounted snow chains If you mount snow chains to the front wheels of 4MATIC vehicles, you may damage components of the vehicle body or chassis.

• Only mount snow chains to the rear wheels of 4MATIC vehicles.
  Observe the following notes when using snow chains:
• Snow chains are only permissible for certain wheel/tire combinations. You can obtain information about this from an authorized Mercedes-Benz Service Center.
• For safety reasons, only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz, or snow chains with the same quality standard.
• Comply with the installation instructions of the snow chain manufacturer.
  If snow chains are installed, the maximum permissible speed is 30 mph (50 km/h).
• Vehicles with Active Parking Assist: do not use Active Parking Assist when snow chains are installed.
• Vehicles with level control: if snow chains are installed, only drive at the raised vehicle level.

You can deactivate ESP® to pull away. This allows the wheels to spin, achieving an increased driving force.
