Engine-Off / Coasting
Principle
Under certain conditions the engine is automati‐
cally decoupled from the transmission in the D
selector lever position. The vehicle continues
traveling with the engine idling to reduce con‐
sumption. Selector lever position D remains en‐
gaged. This driving condition is referred to as
coasting.
Under certain conditions, the engine will not be
operated at idle while coasting but switched off
automatically in vehicles with Mild-Hybrid tech‐
nology. When the engine is switched off, the let‐
tering READY is displayed in the instrument clus‐
ter. The vehicle continues to coast without
consuming fuel. This driving condition is referred
to as engine-off coasting.
As soon as the brake or accelerator pedal is de‐
pressed, the engine is automatically coupled to
the transmission again.
General information
Coasting is a component of the ECO PRO driv‐
ing mode.
Coasting is automatically activated when ECO
PRO driving mode is called via the Driving Dy‐
namics Control.
A proactive driving style helps the driver to use
the function often and supports the efficient ef‐
fect of coasting.
