Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. When
accelerating, shift up before reaching high en‐
gine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.
If necessary, observe the gear shift indicator of
the vehicle, refer to page 84.
Use coasting
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 accel‐
erator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Auto Start/Stop function The Auto Start/Stop function of your vehicle
automatically 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
reduced. Savings can begin within a few sec‐
onds of switching off the engine.
In addition, fuel consumption is also deter‐
mined by other factors, such as driving style,road conditions, maintenance or environmental
factors.
Switch off any functions that
are not currently needed
Functions such as seat heating and the rear
window defroster require a lot of energy and
reduce the range, especially in city and stop-
and-go traffic.
Reel off these functions if they are not needed. The ECO PRO driving program supports the
energy conserving use of comfort features.
These functions are automatically deactivated
partially or completely.
Have maintenance carriedout
Have vehicles maintained regularly to achieve
optimal vehicle efficiency and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 210.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort features, e. g. the cli‐
mate control output, are adjusted.
Under certain conditions the engine is auto‐
matically decoupled from the transmission in
the D selector lever position. The vehicle con‐
tinues traveling with the engine idling to re‐
duce fuel consumption. Selector lever position
D remains engaged.
In addition, context-sensitive instructions are
displayed to assist with an optimized fuel con‐
sumption driving style.Seite 173Saving fuelDriving tips173

You can obtain a selection of replacement
bulbs at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is a danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always reel off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlights
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is a danger of fatal
injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.
