For going downhill take your foot off the acceler‐
ator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during
longer stops
Switching off the engine
Switch off the engine during longer stops, for in‐
stance at traffic lights, railroad crossings or in
traffic congestion.
Auto Start/Stop function
The Auto Start/Stop function of the vehicle auto‐
matically switches off the engine during a stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are re‐
duced. Savings can begin within a few seconds
of switching off the engine.
In addition, fuel consumption is also determined
by other factors, such as driving style, road con‐
ditions, maintenance or environmental factors.
Switch off any functions that are
not currently needed
Functions such as seat heating and the rear win‐
dow defroster require a lot of energy and in‐
crease fuel consumption, especially in city and
stop-and-go traffic.
Switch off these functions if they are not needed.
The ECO PRO driving mode supports the en‐
ergy conserving use of comfort features. These
functions are automatically deactivated partially
or completely.
Have maintenance carried out
Have the vehicle maintained regularly to achieve
optimal vehicle efficiency and service life. BMW
recommends that maintenance work be per‐
formed by a BMW service center.

tem, refer to page
ECO PRO
Concept
ECO PRO supports a driving style that saves on
consumption. For this purpose, the engine con‐
trol and comfort features, for instance the climate
control output, are adjusted.
Under certain conditions the engine is automati‐
cally decoupled from the transmission in the D
selector lever position. The vehicle continues
traveling with the engine idling to reduce con‐
sumption. The D selector lever position remains
engaged.
In addition, context-sensitive information, ECO
PRO tips, can be displayed to assist with a fuel-
efficient driving style.
The achieved extended range is displayed in the
instrument cluster as bonus range.
