Driving hints
Avoid high engine speeds
Driving at low engine speeds lowers fuel con‐
sumption and wear.
Pay attention to the shift point indicator, see
page 110, in the vehicle, if fitted.
Make use of overrun mode
When approaching a red traffic light, take your
foot off the accelerator and allow the vehicle to
roll.
On downward stretches, take your foot off the
accelerator and allow the vehicle to roll.
The fuel supply is interrupted in overrun mode.
Switch off the engine if
stopping for a relatively long
time
Stopping the engine
When you stop the vehicle for longer periods,
for example at traffic lights, railway crossings
or in traffic jams, switch off the engine.
Auto Start Stop function
The Auto Start Stop function of the vehicle
shuts off the engine automatically during a
stop.
If the engine is switched off and then started
again, the fuel consumption and emissions are
reduced compared with a permanently running
engine. Savings can be made just by stopping
the engine for a few seconds.
Fuel consumption also depends on other fac‐
tors, such as driving style, road condition,
maintenance or environmental factors, for ex‐
ample.

Switch of functions which
are not currently required
Functions such as seat heating or rear window
heating require a great deal of energy and re‐
duce the range, especially in city traffic and
stop-and-go traffic.
Switch these functions off if they are not re‐
quired.
Have the maintenance done
Have the vehicle serviced regularly to achieve
optimal economy and lifetime. BMW recom‐
mends having maintenance work carried out
by a BMW Service Partner.

tem, see page 229.
