The condition of charge of the high-voltage bat-
tery is thus systematically controlled. In addi-
tion, the control function takes into account
that:
R
the fuel savings through the use of electrical
energy can vary, depending on the route (e.g.
urban, interurban or highway)
R
the use of electrical energy is held available in
particular for electric operation (e.g. urban
routes)
The vehicle thus automatically selects the opti-
mum driving type for the respective section of
the route.
The route-based operating strategy is available
under the following conditions:
R
drive program E is selected
R
HYBRID driving mode is selected
R
active route guidance is activated
R
suitable map data is available
When the route-based operating strategy is
being used, the area in front of the vehicle is
shown as green in the multifunction display.
