Vehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment 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 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
raises fuel consumption.
Check the tire inflation
pressure regularly
Check and, if necessary, correct the tire inflation
pressure at least twice a month and before start‐
ing on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay
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 vehicle
driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
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 en‐
gine speeds.

When you reach the desired speed, shift into the
highest applicable gear and drive with the en‐
gine speed as low as possible and at a constant
speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
The gear shift indicator of your vehicle indicates
the most fuel efficient gear.
Use coasting conditions
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 ac‐
celerator 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.
Fuel savings are achieved after the vehicle is
switched off for only approx. 4 seconds.
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 con‐
sume additional fuel, especially in city and stop-
and-go traffic.
Therefore, switch off these functions if they are
not actually needed.
Have maintenance carried out
Have vehicles maintained regularly to achieve
optimal vehicle economy and operating life.
Have the maintenance carried out by your serv‐
ice center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 277.
ECO PRO
The concept
ECO PRO supports a driving style that saves on
fuel consumption. For this purpose, the engine
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.
The extension of the range that is achieved as a
result can be displayed in the instrument cluster.
Activating ECO PRO
Press button repeatedly until ECO PRO
is displayed in the instrument cluster.
Display in the instrument cluster
ECO PRO bonus range
An extension of the range can be
achieved by an adjusted driving
style.
This may be displayed as the bo‐
nus range in the instrument clus‐
ter.
Driving style
In the tachometer, a mark in the
bar display indicates the current
efficiency of the driving style cor‐
responding to the accelerator
pedal position.
▷Blue display: efficient driving style as long as
the mark moves within the blue range.
▷Gray display: adjust driving style, e. g. by
backing off the accelerator pedal.

The display switches to blue as soon as all con‐
ditions for fuel-economy-optimized driving are
met.
ECO PRO Tip - driving instruction
The arrow indicates that the driv‐
ing style can be adjusted to be
more fuel efficient by backing off
the accelerator.
