BMW X5: Engine-Off / Coasting
Principle
Under certain conditions the engine is automatically decoupled from the transmission in the D selector lever position. The vehicle continues traveling with the engine idling to reduce consumption.
Selector lever position D remains engaged.
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 technology.
When the engine is switched off, the lettering READY is displayed in the instrument cluster.
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 depressed, the engine is automatically coupled to the transmission again.
General information
Coasting is a component of the ECO PRO driving mode.
Coasting is automatically activated when ECO PRO driving mode is called via the Driving Dynamics Control.
A proactive driving style helps the driver to use the function often and supports the efficient effect of coasting.
