Electrical Fuses

Notes on Car Electrical System

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 color and fuse rating. The fuse ratings and further information to be observed can be found on the fuse assignment diagram. Fuse assignment diagram: in the vehicle document wallet.

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 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 tyres

WARNING
The risk of injury through damaged tires can cause tire pressure loss.

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

WARNING
The risk of hydroplaning due to 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: ã in (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, prior to a long journey or driving off-road:
  • Check the tire pressure
  • Visually inspect wheels and tires for damage.
  • 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).

Notes on snow chains Owner’s Manual

WARNING
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 rare 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 raised vehicle level
  • Vehicles with rear-axle steering: if snow chains are installed, only drive with snow chain mode active
  • You can deactivate ESP® to pull away
  • This allows the wheels to spin, achieving an increased driving force.

Activating or deactivating snow chain mode

Multimedia system:
Home >  Setting > Car

  • Activate or deactivate Snow Chain Mode.
  • When the function is active, the vehicle behaves as if snow chains were installed. For example, the maximum steering movement of the rear wheels is limited and the turning circle is thus increased. Additionally, parts of the driving and driving safety systems are not available when snow chain mode is active.

How to Replace Fuse in the 2023 Mercedes S-CLASS

  1. Locate the Fuse Box: The fuse box in most vehicles, including the Mercedes S-Class, is typically located either under the dashboard on the driver’s side or in the engine compartment. 

  2. Identify the Fuse: Once you’ve located the fuse box, open the cover. Inside, you’ll find multiple fuses arranged in rows. Each fuse is usually labeled with its function and the appropriate amp rating. 

  3. Remove the Blown Fuse: Using a fuse puller tool or a pair of needle-nose pliers, carefully grasp the blown fuse and pull it straight out of its socket. Be gentle to avoid damaging the fuse box or surrounding components.

  4. Insert the New Fuse: Take a new fuse with the same amp rating as the one you removed. Make sure it’s the correct type and rating to avoid electrical issues or damage to your vehicle. Align the new fuse with the socket and push it firmly into place until it’s fully seated.

  5. Close the Fuse Box Cover: Once you’ve replaced the fuse, securely close the fuse box cover.

  6. Test the Circuit: After replacing the fuse, it’s a good idea to test the circuit to ensure everything is working correctly. Turn on the corresponding electrical component (e.g., lights, radio) and check if it operates as expected. 

  7. Dispose of the Old Fuse: Properly dispose of the blown fuse. It’s a good idea to keep spare fuses in your vehicle in case you encounter another electrical issue in the future.
