Route-ahead assistant
Principle
The function helps to save fuel and supports an
anticipatory driving style. Using the navigation
data, certain sections of the route ahead can be
detected early and information can be given.
General
The recognised sections of the route, such as
built-up areas or bends ahead, for example, re‐
quire a reduction in speed.
The alert is also given if the section of the route
ahead cannot yet be detected when driving.
The alert is shown until the section of the route
is reached.
If there is an instruction, the vehicle's speed and
its consumption can be reduced by coming off
the gas and coasting until the route section is
reached.
Depending on the situation, the system also in‐
dependently used the engine brake by interrupt‐
ing the coasting function, see page 261.
Operating requirements
▷ ECO PRO driving mode is activated.
▷ Navigation data is up to date.
▷ "Adjust speed limits" is switched on, see
page 202.
