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 selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Information Coasting is a component of the ECO PRO, re‐
fer to page 184, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A proactively 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 under one of the
following conditions.▷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 exces‐
sive 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 met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.
The driving status Coast can be influenced
with the shift paddles.
