Coasting
Concept
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.
As soon as you step on the brake or accelerator
pedal, the engine is automatically coupled again.
General information
Coasting is a component of the ECO PRO driv‐
ing mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
A proactive driving style helps the driver to use
the function often and supports the efficient ef‐
fect of coasting.
