ECO start/stop function (all vehicles
except plug-in hybrid)
Introduction
This section describes the ECO start/stop
function for all vehicles except PLUG-IN
HYBRID vehicles. Information on the ECO
start/stop function on PLUG-IN HYBRID vehi-
cles can be found in the "PLUG-IN HYBRID
operation" section in the Digital Operator's
Manual.
The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain conditions.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
