Mercedes-Benz S-CLASS SEDAN 2023 Function Of EBD User Manual
Electronic Brake-force Distribution (EBD) is a sophisticated braking system that dynamically adjusts the braking force to each wheel according to the vehicle’s speed, load, and road conditions. By doing so, it ensures that the vehicle stops safely and effectively, especially in emergency situations. Unlike traditional braking systems that distribute the brake force evenly among all wheels, EBD optimizes the braking force based on the weight distribution of the vehicle. This enables more effective and efficient braking, resulting in improved stopping power and stability. The Mercedes-Benz S-Class Sedan 2023 is expected to feature EBD, which is likely to be integrated with other advanced safety technologies such as Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and Brake Assist. These systems work in harmony to provide a safer and more comfortable driving experience for both the driver and passengers.
Function Of EBD
Electronic Brakeforce Distribution (EBD) is characterized by the following:
- Monitoring and regulating the brake pressure on the rear wheels.
- Improved driving stability when braking, especially on bends.
The function of STEER CONTROL
STEER CONTROL assists you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization.
This steering recommendation is given in the following situations:
- Both right wheels or both left wheels are on a wet or slippery road surface when you brake
- The vehicle starts to skid
System limits
STEER CONTROL may be impaired or may not function in the following situations:
- ESP® is deactivated.
- ESP® is malfunctioning.
- The steering is malfunctioning.
If ESP® is malfunctioning, you will be assisted further by the electric power steering.
HOLD function
HOLD function
The HOLD function holds the vehicle at a standstill without requiring you to depress the brake pedal, e.g. while waiting in traffic.
The HOLD function is only an aid. The responsibility for the vehicle safely standing still remains with the driver.
System limits
The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary.
- The incline must not be greater than 30%.
Activating/deactivating the HOLD function
WARNING
Risk of an accident due to the HOLD function being active when you leave the vehicle
If the vehicle is only braked with the HOLD function it could, in the following situations, roll away:
- If there is a malfunction in the system or in the power supply.

After a short time, Hill Start Assist no longer holds the vehicle.
Swiftly move your foot from the brake pedal to the accelerator pedal. Do not leave the vehicle when it is being held by Hill Start Assist.
ATTENTION ASSIST
The function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monotonous journeys, e.g. on highways and trunk roads. If indicators of fatigue or increasing lapses in concentration on the part of the driver are detected, the system suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot always detect fatigue or lapses in concentration in time. The system is not a substitute for a well-res-ted and attentive driver. On long journeys, take regular breaks in good time that allow for adequate recuperation.
You can choose between two settings:
- Standard: normal system sensitivity.
- Sensitive: higher system sensitivity. The driver is warned earlier and the attention level detected by ATTENTION ASSIST has adapted accordingly.
If fatigue or increasing inattention is detected, the warning appears in the driver display: ATTENTION ASSIST: Take a Break!. you can acknowledge the message and take a break if necessary. If you do not take a break and ATTENTION ASSIST continues to detect increasing lapses in concentration, you will be warned again after a minimum of 15 minutes.
If ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the System Suspended message appears. If the driver display shows a warning, a service area search is offered in the multimedia system.
You can select a rest area and start navigation to this rest area.
When you restart the vehicle, ATTENTION ASSIST is automatically switched on. The last selected sensitivity level remains stored.
The following information is displayed in the driver’s display:
- The length of the journey since the last break R The attention level determined by ATTENTION ASSIST:
- The more segments 1 of the circle displayed, the higher the detected attention level.
- Fewer segments 1 are displayed in the circle as the attention level decreases.
System limits
ATTENTION ASSIST is active in the 37 mph (60 km/h) to 124 mph (200 km/h) speed range. The microsleep detection function is available at a speed of 12 mph (20 km/h) and above. If the system is not available due to an error, the ATTENTION ASSIST warning light is permanently lit Û in the driver display
Particularly in the following situations, ATTENTION ASSIST functions only in a restricted manner, and warnings may be delayed or not occur:
