DRIVING TIPS
Avoid high RPM
Driving at low engine speeds lowers fuel con‐
sumption and reduces wear.
If necessary, observe the vehicle's gear shift indi‐
cator.
Using coasting overrun mode
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
For going downhill take your foot off the acceler‐
ator and let the vehicle roll.
The fuel supply is interrupted in coasting overrun
mode.
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 jam.
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.
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.
Also refer to BMW Maintenance System.
ECO PRO
Principle
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.
Steptronic transmission: under certain conditions
the engine is automatically decoupled from the
transmission in the D selector lever position. The
vehicle continues traveling with the engine idling
to reduce consumption. The D selector lever po‐
sition remains engaged.
In addition, context-sensitive information, ECO
PRO tips, are displayed to assist with an efficient
driving style.
The achieved extended range is displayed in the
instrument cluster as bonus range.
