Eco Coast
Eco Coast essentially deactivates engine braking,
allowing the vehicle to roll freely.
When the driver releases the accelerator pedal,
the transmission is automatically disengaged
from the engine to allow the vehicle to roll as far
as possible, which helps reduce fuel consump-
tion.
This feature is primarily intended to be used in
driving situations where the vehicle can roll freely,
such as down gentle hills or when a decrease in
speed is expected, such as when approaching an
intersection or a traffic light.
Eco Coast enables proactive driving with as little
braking as possible.
Depending on the driving situation, Eco and Eco
Coast can be used in different ways to help
reduce fuel consumption:
•
With Eco activated: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching a
traffic light or intersection).
or
•
With Eco deactivated: engine braking can
be used when the vehicle will only roll for
a short distance (in heavy traffic, etc.) or
when driving down hills.
To help keep fuel consumption as low as possi-
ble, Eco Coast should not be used in traffic situa-
tions where the brakes have to be used fre-
quently.

pedal is released completely if:
