I remember reading a few posts back that when the sat nav is on it works out where best to use the battery; is this just with comand or the garmin as well?
I know it does with Comand as long as you put the car into Eco mode on the Dynamic Select. Manual section below just says suitable route guidance which implies Comand or Garmin. The final sentence says how you can see route based energy management is active. [emoji3] Glad I spent the 9 months waiting for the car reading the manuals - the iPhone app version of MB Guides is really handy.
Route-based energy management
For route-based energy management, the system factors in information about the expected route when route guidance is active.
The information on the route is provided by the multimedia system and includes the following:
road categories
speed limitations
data on downhill gradients
The use of electric energy is automatically optimally distributed from the beginning to the end of the journey, using information about the route. The distribution is pre-emptive and takes into consideration:
the sections of the journey ahead
the energy consumption on the whole route
The charge status of the high-voltage battery is thus systematically controlled. In addition, the control function takes into account that:
the fuel savings through the use of can vary, depending on the route (e.g. urban, interurban or motorway)
the use of electrical energy is held available in particular for electric operation (e.g. urban routes)
The vehicle thus automatically selects the optimum driving mode for the respective section of the route.
Route-based energy management is available under the following conditions:
drive program E is selected
HYBRID driving mode is selected
active route guidance is activated
suitable map data is available
When route-based energy management is in operation, the area in front of the vehicle is shown as green in the multifunction display.
