Coasting
Principle
The engine is automatically disconnected from
the gearbox in selector lever position D under
certain circumstances. The vehicle continues to
roll in idle to reduce consumption. Selector lever
position D remains engaged.
This vehicle condition is called coasting.
As soon as the brake or accelerator pedal is
pressed, the engine is automatically connected
again.
General
Coasting is a component of the ECO PRO drive
mode and the COMFORT drive mode.
Coasting is automatically activated by calling up
the ECO PRO drive mode or COMFORT drive
mode via the Driving Experience Control and
cannot be deactivated.
A precautionary driving style helps to use the
function frequently and supports the consump‐
tion-reducing effect of coasting.
Operating requirements
The function is available in the speed range from
approx. 25 km/h, 16 mph to 160 km/h, 100 mph.
