Saving fuelVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove auxiliary mirrors, roof or rear luggage
racks which are no longer required following use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 174Driving tipsSaving fuel174
Online Edition for Part no. 01 40 2 960 707 - II/15

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 85.
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 207.
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 175Saving fuelDriving tips175

BMW maintenance system The maintenance system indicates required
maintenance measures, and thereby provides
support in maintaining road safety and the op‐
erational reliability of the vehicle.
In some cases scopes and intervals may vary
according to the country-specific version. Re‐
placement work, spare parts, fuels and lubri‐
cants and wear materials are calculated sepa‐
rately. Additional information is available from
the service center.
Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service recog‐
nizes the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance corresponding to your
user profile.
Detailed information on service requirements,
refer to page 84, can be displayed on the Con‐
trol Display.Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control. Your service center will read out this data and
suggest the right array of service procedures for your vehicle.
Therefore, hand your service specialist the re‐
mote control with which the vehicle was driven
most recently.
Storage periods Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if needed,
changing the engine oil and the microfilter/
activated-charcoal filter.
