2014 BMW 640I GRAN COUPE climate control

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.
Automatic Engine 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
consume 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
service center.
Please also note the BMW Maintenance Sys‐
tem, refer to page 208.
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.
The extension of the range that is achieved as
a result can be displayed in the instrument
cluster.
At a glance
The system includes the following
EfficientDynamics functions and displays:▷ECO PRO bonus range, refer to page 181.▷ECO PRO tips driving instruction, refer to
page 182▷ECO PRO climate control, refer to
page 181.
Activating ECO PRO
Press button repeatedly until ECO
PRO is displayed in the instrument
cluster.

ECO PRO climate control
"ECO PRO climate control"
The climate control is adjusted to be fuel-effi‐
cient.
By making a slight change to the set tempera‐
ture, or slowly adjusting the rate of heating or
cooling of the passenger compartment, fuel
consumption can be economized.
The outputs of the seat heater and the exterior
mirror heating are also reduced.
The exterior mirror heating is made available
when outside temperatures are very cold.
ECO PRO potentialThe percentage of potential savings that can
be achieved with the current configuration is
displayed.
Display in the instrument cluster
Display in the instrument display
When ECO PRO mode is activated, the display
switches to a special configuration.
Some of the displays may differ from the dis‐
play in the instrument cluster.
ECO PRO bonus range An extension of the range can
be achieved by an adjusted driv‐
ing style.
This may be displayed as the
bonus range in the instrument
cluster.
The bonus range is shown in the range display.
The bonus range is automatically reset every
time the vehicle is refueled.
Driving style
In the tachometer, a mark in the bar display in‐
dicates the current efficiency of the driving
style.
Mark in the CHARGE area, arrow 1: display for
energy recovered by coasting or when braking.
Mark in the POWER area, arrow 2: display
when accelerating.
The efficiency of the driving style is shown by
the color of the bar:
▷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
conditions for fuel-economy-optimized driving
are met.

Tire age
DOT … 1013: the tire was manufactured in the
10th week 2013.
Recommendation
Regardless of wear, replace tires at least every
6 years.
Uniform Tire Quality GradingQuality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified governmenttest surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
If necessary, have the vehicle towed.◀
RSC – Run-flat tires
Run-flat tires, refer to page 201, are labeled
with a circular symbol containing the letters RSC marked on the sidewall.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.Seite 198MobilityWheels and tires198
