vance and an additional symbol show the up‐

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when transmission position D is engaged.
The vehicle continues traveling with the engine
idling to reduce fuel consumption. Transmission
position D remains engaged.
This driving condition is referred to as coasting.
As soon as the brake or accelerator pedal is de‐
pressed, the engine is automatically coupled to
the transmission again.
Hints
Coasting is a component of the ECO PRO, refer
to page 181, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control, refer to page 127.
The function is available in a certain speed
range.
A forward-looking driving style helps the driver
to use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available if one of the follow‐
ing conditions is satisfied.
▷ DSC OFF or TRACTION activated.
▷ Driving in the dynamic limit range and on
steep uphill or downhill grades.
▷ Battery charge status temporarily too low or
vehicle electrical system drawing excessive
current.
▷ Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in a
speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are satisfied:
▷ Accelerator pedal and brake pedal are not
operated.
▷ The selector lever is in transmission position
D.
▷ Engine and transmission are at operating
temperature.
