The ECO display shows an evaluation of your driv-ing style on the driver’s display depending on the situation. This enables you to check the efficiency of your driving style and adjust it if necessary. The ECO Display menu shows a ball 2 that will roll forwards or backward on a stylized road in the direction of travel according to the driving characteristics.
Above and below the road, lines mark the area for an efficient driving style 3. Ball 2 will light up in green if it is rolling within these lines. Outside the lines, the ball will light up in orange.

The ECO display assesses the following criteria for an economical driving style:

  • Coasting at the right times
  • Consistent speed
  • Moderate acceleration

The overall assessment of your driving style “from start” is indicated using stars 1. It starts with five empty stars, which you can fill one after the other if you drive efficiently. When all five stars are filled, a glow will appear in the background. You can call up the ECO Display function via the Classic and Exclusive menus (/ page 322).

ECO Assist function (vehicles with 48 V on-board electrical system)
For plug-in hybrids, note the ECO Assist information (/ page 216).
ECO Assist is active only in drive programs, and A. ECO Assist analyzes data for the vehicle’s expected route. This allows the system to optimally adjust the driving style for the route ahead, save fuel and recuperate. If the system detects an event ahead and the vehicle nears the event, ECO Assist will calculate the optimum speed for maximum fuel economy and recuperative energy based on the distance, speed and downhill gradient.

If the deceleration provided by ECO Assist is not sufficient, you must also brake with the service brake. This is especially the case if, for example, you pull away again in slow-moving traffic and the distance to the vehicle in front is very short.

  1. Foot off the accelerator” recommendation
  2. Route event ahead

If a routed event ahead or a vehicle driving in front is detected which requires an adjustment to your driving style to ensure greater efficiency, the corresponding symbol 2 and the 2023 Mercedes S-CLASS ECO Start-Stop Function fig-6symbol (gray) will be displayed. If you release the accelerator pedal, the 2023 Mercedes S-CLASS ECO Start-Stop Function fig-6symbol will turn green, and recuperation in over-run mode will be initiated. If the deceleration is not sufficient, also apply the service brake. If ECO Assist intervenes for a routed event ahead (not for a vehicle in front) and you then press the accelerator pedal again, you end ECO Assist’s control.

The ECO Assist display is hidden again in the following cases:

  • You do not react to the ECO Assist recommendation for a long time.
  • You press the accelerator pedal while ECO Assist is intervening for a route event ahead (not for a vehicle in front).
  • ECO Assist cannot identify any further recommendations from the route ahead.

In addition to a vehicle in front 2023 Mercedes S-CLASS ECO Start-Stop Function fig-7

, ECO Assist can detect the following route events 2 depending on the vehicle’s equipment:

  • Traffic circle
  • curve
  • Sharp curve
  • Intersection
  • Downhill gradient
  • Speed limit
  • In drive program A, ECO Assist only reacts to the route event “Vehicle in front”.

System limits
If the calculated route is adhered to when route guidance is active, ECO Assist will operate with greater accuracy. The basic function is also available without active route guidance. Not all information and traffic situations can be foreseen. The quality depends on the map data.
ECO Assist is only an aid. The driver is responsible for keeping a safe distance from the vehicle in front, for vehicle speed, and for braking in good time.

The system may be impaired or may not function in the following situations:

  • If there is poor visibility, e.g. due to insufficient illumination of the road, highly variable shade conditions, rain, snow, fog or heavy spray.
  • If there is glare, e.g. from oncoming traffic, direct sunlight or reflections.
  • If the windshield is dirty in the vicinity of the multifunction camera.
  • If the multifunction camera is fogged up, damaged or obscured.
  • If road signs are hard to detect, e.g. due to dirt, snow or insufficient lighting, or because they are obscured.
  • If the information in the navigation system’s digital map is incorrect or out of date.
  • If signs are ambiguous, e.g. road signs in the road- works or in adjacent lanes.
  • If the radar sensors are dirty or obscured.
  • When you drive on roads with steep uphill or downhill gradients.
  • If there are narrow vehicles in fronts, such as bicycles or motorcycles.

2023 S-CLASS Regenerative Brake System (plug-in hybrid) 

The function of the recuperative brake system
Depending on the selected recuperation level, the electric motor will be operated as an alternator when in overrun mode and during braking in order to charge the high-voltage battery during driving. As soon as you take your foot off the accelerator pedal when the vehicle is in motion and in trans-mission position h, recuperation in overrun mode will be initiated.

The higher the recuperation, the stronger the braking effect will be during coasting and the more electrical energy will be fed into the high-voltage battery.
The deceleration in overrun mode may not be sufficient depending on the driving conditions. Decelerating to a standstill is not possible. Also, brake with the service brake if necessary. Always adapt your speed to the driving conditions and keep a sufficient distance.

The recuperative brake system has the following characteristics:

  • Supports braking with electronically controlled brake force boosting R converts the kinetic energy of the vehicle into electric energy
  • If you brake hard, the mechanical brake will also be used. This means that the maximum recuperative energy cannot be recovered. The more you drive and brake in an anticipatory manner, the more efficiently energy can be recuperated.

System limits
The braking effect of the electric motor during recuperation in overrun mode may be reduced or may not be available at all in the following situations:

  • When the high-voltage battery state of charge increases
  • If the high-voltage battery is not yet at a normal operating temperature

In these cases, the desired deceleration will be set by the brake control system.

Manually Setting Recuperative Deceleration
NOTE Mercedes-AMG vehicles

  • Observe the notes in the Supplement.
    You could otherwise fail to recognize dangers.

You can use the steering wheel paddle shifters to adjust the intensity of recuperation in drive programs H, B and EL.2023 Mercedes S-CLASS ECO Start-Stop Function fig-4
