Saving fuelVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions 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.
The implementation of certain measures, driv‐
ing style and regular maintenance can have an
influence on fuel consumption and on the envi‐
ronmental impact.
Remove unnecessary cargoAdditional 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 values in
various ways, for instance fuel consumption
can be influenced by the size of the tires.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion 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 fastest way for the cold engine to
reach its 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 looking ahead reduces
fuel consumption.Seite 172Driving tipsSaving fuel172
Online Edition for Part no. 01 40 2 926 810 - X/13

Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching
high engine 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.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
The gear shift indicator of your vehicle indi‐
cates the most fuel efficient gear.
Use coasting When approaching a red light, take your foot
off the accelerator and let the vehicle coast to
a halt.
On a downhill gradient, take your foot off the
accelerator 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.
Using this system can cause certain compo‐
nents of the vehicle to become worn prema‐
turely.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.
Therefore, switch off these functions if they
are not actually needed.
The ECO PRO driving program supports the
energy conserving use of comfort functions.
These functions are automatically deactivated
partially or completely.
Have maintenance carried
out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
The maintenance should be carried out by
your service center.
Also note the BMW Maintenance System, refer
to page 204.
ECO PRO
The concept ECO PRO supports a driving style that saves
on fuel consumption. For this purpose, the en‐
gine control and comfort functions, e. g. the
climate control output, are adjusted.
In addition, context-sensitive instructions can
be displayed that assist in driving in a manner
that optimizes fuel consumption.
In the instrument display, the extension of the
range achieved by this can be displayed as a
bonus range.Seite 173Saving fuelDriving tips173

In order to always ensure your mobility, you will find important information on operating fluids,wheels and tires, maintenance and Roadside Assistance in the following.Online Edition for Part no. 01 40 2 926 810 - X/13

Refill in good time
The reducing agent must be replenished
as soon as the Reserve display appears, other‐
wise the engine cannot be restarted.◀
Diesel exhaust fluid on minimum The engine will continue to runeven when the display shows --,
as long as it is not switched off
and all other operating condi‐
tions are satisfied, sufficient fuel
for example.
Engine does not start
Do not continue driving to the limit of the
remaining travel distance. Otherwise, you will
not be able to restart the engine after switch‐
ing it off.◀
Filling with incorrect fuel A Check Control message is displayed when
the tank is filled with the incorrect fuel.
After adding the wrong fuel, contact your serv‐
ice center.
System defect
A Check Control message is displayed when
there is a system defect.
Have the diesel exhaust fluid
replenished
The reducing agent is added by the service
center within the context of regular mainte‐
nance. Provided you observe this maintenance
schedule, it is normally necessary to replenish
the fluid once between maintenance appoint‐
ments.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, for example, if the vehicle is driven in
a particularly sporty style or if it is driven at
high altitudes.The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible that reducing agent may also need to be re‐
plenished between regular maintenance ap‐
pointments if it is exposed to temperatures be‐
low + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before starting to drive.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃ the fill
level in some cases cannot be measured.
After adding reducing agent, the reserve dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid
When working with reducing agent in
closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may escape.◀
Keeping Diesel exhaust fluid out of reach
of children
Keep reducing agent out of reach of children◀
Avoid contact with surfaces
Avoid contact of reducing agent with sur‐
faces of the vehicle. Damage could result.◀Seite 184MobilityFuel184

Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Detailed information on service requirements,
refer to page 82, 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 necessary,
changing the engine oil and the microfilter/
activated-charcoal filter.
