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.
Have maintenance carried out
Have the vehicle maintained regularly to achieve
optimal vehicle efficiency and service life. BMW
