What is the recovery mode in Mercedes?

The eVito Tourer uses a process called recuperation that recovers energy when the vehicle is decelerating to help you efficiently manage your vehicle’s range. You can select 5 different modes via the gearshift paddles. The greater the recuperation, the faster you decelerate and therefore, the more energy your vehicle will regenerate:

D- – This mode is designed to get maximum range from your eVito Tourer. With the fastest deceleration, it recovers the most energy. As the deceleration is so strong, your brake lights will be automatically activated. D- When you ease off the accelerator in D-, your vehicle will slow down less quickly and recover a little less energy than D-. Generally, this mode will activate your brake lights. D This mode is good for faster paced traffic traveling at a relatively constant speed and the vehicle returns to D every time you start the motor. It has a gradual deceleration feel – like putting a diesel vehicle into a lower gear. Some energy is recovered, but not as much as D-. Brake lights are generally not automatically activated in this mode. D+ This is a sailing mode, meaning your vehicle will decelerate naturally – like coasting to a stop in a diesel vehicle. No energy is recovered into the battery. It is useful on long downhill sections of main roads, as you will be able to ‘sail’ with no drag from the electric motor. D Auto With a long pull of either paddle shifter, the intelligent mode D Auto is activated. It uses a radar sensor and navigation data to automatically adjust the recuperation level to the traffic situation – so you don’t have to.

How do I reset the Mercedes Collision Prevention Assist Plus inoperative?

How to fix it? – Firstly, always stay alert and aware while on the road; keep a safe distance from other vehicles and find a safe place to pull over and turn the engine off. A low battery or extreme outside temperature can affect the sensors, so restarting the car can reboot the system after which it should work fine.

  1. Leaving the car to idle for 10-15 minutes can often help it recharge enough for the system to kick back in.
  2. If restarting doesn’t work, check the front bumper where the sensors sit; if it is covered in debris such as dirt or ice, clear it off to unblock the sensors and restart the car to allow them to read the road.

Another fix in the list should be clearining error codes using star xentry software or any other software, but ofcourse dealer software is always the best. Try simple to clear the memory of the car as in many cases it helps as well and the reason is because car has ECU (computer) and like any other electronic computer it does calculations and keeps stocking many information and sometimes it just gets clogged and that’s why simple clear fault codes help.

After you’ve tried these the cheapest ways to fix warning message, let’s go to the mechanical part. Carefully remove front bumper from the car, once removed you will see like a black box like a smart phone (it’s radar sensor) attached on the bamber with clips. Gently unplug wires and take a look if there is any moisture on both connectors, car’s and sensor itself if there is, it is a tell tell sign that sensor has been damaged by water or moisture and needs to replaced in order to fix warning message, another sign when mercedes-benz radar sensor needs to be replaced is damage to sensor itself, for example collision or bad smell coming out of part, it also means part has had some kind of short circuit and burnt.

Bear in mind that every electrical part has it’s life-time and it is normal that radar sensors fails. Finally, if you did all the checks and options above and still seeing “collision assist plus inoperative” message it might be that car’s software may need updating.
