ECO*
ECO 14 is an innovative Volvo function for
automatic-gearbox cars, capable of reducing
fuel consumption by up to 5%, depending on
the driver's driving style. The function gives
the driver the option of a more active environ-
mentally conscious way of driving.
General
The following are changed
upon activation of the ECO
function:
•
Gearbox gearshift points.
•
Engine management and response from
the accelerator pedal.
•
Start/Stop function - the engine can also
auto-stop before the car has stopped
down to being completely stationary.
•
The Eco Coast function is activated -
engine braking ceases.
•
Climate control system settings - some
electricity consumers are deactivated or
operate at reduced power.
NOTE
When the ECO function is activated, sev-
eral parameters in the climate control sys-
tem's settings are changed, and several
electricity consumer functions are
reduced. Certain settings can be reset
manually, but full functionality is only
restored by deactivating the ECO function.
ECO - Operation
ECO On/Off
ECO symbol
The ECO function is deactivated when the
engine is switched off, and must therefore be
activated after each time the engine is
started. There are exceptions for certain
engines. However, it is easily verified by
means of both the combined instrument
panel
ECO
symbol and the ECO button lamp
illuminating when the function is activated.
ECO function On or Off
Disengaged ECO function is
indicated by the combined
instrument panel
ECO
sym-
bol and the ECO button lamp
extinguishing. The function is
then switched off until it is
reactivated with the ECO
button.
Eco Coast - Function
The Eco Coast subfunction means in practice
that engine braking is deactivated, meaning in
turn that the car's kinetic energy is used to
coast for longer distances. When the driver
releases the accelerator pedal the gearbox is
automatically disengaged from the engine
whose speed is reduced to idling speed with
minimum consumption.
This function is intended for use in the event
of an anticipated reduction in speed, e.g. to
coast forward to an intersection or a red light.
Eco Coast enables proactive driving where
the driver can use the so-called "Pulse &
Glide" technique and a minimum of braking.
Combination On and Off
A combination of Eco Coast and temporarily
deactivated ECO function can also collec-
