2012 BMW 640I CONVERTIBLE check engine

The rear wheels are turned to the same angle as
the front wheels.
In
critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.
1. With the engine running, turn the steering
wheel

all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.
2. Have the system checked if the warning
lamp

does not go out after moving the steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure
that the rear axle steering is deactivated
when using snow chains, refer to page 235.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 103.
SPORT
Consistently sporty tuning of the Integral Active
Steering for greater driving agility.
NORMAL
Balanced tuning of the Integral Active Steering
for optimal traveling comfort.
Malfunction
In the event of a malfunction, the steering wheel
must be turned further, while the vehicle re‐
sponds more sensitively to steering wheel
movements in the higher speed range. The stability-enhancing intervention may be de‐
activated.
Proceed cautiously and drive defensively.
Have the system checked.
Dynamic Driving Control*
The concept
Dynamic Driving Control can be used to adjust
the

driving dynamics of the vehicle. Several pro‐
grams are available for this purpose; they can be
activated using the two Dynamic Driving Control
buttons.

Measurement
Measurements
are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷ By the front* sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.
▷ By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion.

Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:
▷ With tow bars and trailer hitches.
▷ With thin or wedge-shaped objects.
▷ With low objects.
▷ With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move
into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected. False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷
In heavy rain.
▷ When sensors are very dirty or covered in
ice.
▷ When sensors are covered in snow.
▷ On rough road surfaces.
▷ In large buildings with right angles and
smooth

walls, e.g., in underground garages.
▷ In heavy exhaust.
▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Select transmission position R with the engine
running.
Switching off automatically
The

system switches off and the LED goes out:
▷ After approx. 160 ft/50 m when driving for‐
ward.
▷ Above approx. 22 mph/36 km/h when driv‐
ing forward.
Switch on the system again if necessary.
Switching on/off manually Press the button.

Interior equipment
Integrated universal remote
control*
The concept
This system can replace up to three different
hand-held transmitters for various types of re‐
mote-controlled equipment, such as garage
doors or lighting systems.
The hand-held transmitter signal can be pro‐
grammed on one of the three memory buttons.
The
corresponding device can then be operated
using the programmed memory button.
The LED indicates that a signal is being trans‐
mitted.
When selling the vehicle, delete the stored pro‐
grams for security reasons.
During programming
During programming and before activat‐
ing a device using the universal remote control,
ensure that there are no people, animals, or ob‐
jects in the range of movement of the remote-
controlled device; otherwise, there is a risk of
injury or damage.
Also follow the safety instructions of the hand-
held transmitter.◀
Compatibility
If this symbol is printed on the packaging
or in the instructions of the hand-held
transmitter, the remote-controlled de‐
vice is generally compatible with the universal
remote control.
If you have any questions, please contact:
▷ Your service center.
▷ www.homelink.com on the Internet. Programming
▷
LED, arrow 1.
▷ Memory buttons, arrow 2.
Fixed-code hand-held transmitters
1. Switch on the ignition.
2. Initial setup:
Press

both outer buttons 1 and 3 for approx.
20 seconds until the LED flashes.
All programs of the three memory buttons,
arrow 2, are cleared.
3. Hold the hand-held transmitter a distance of
approx.

2 to 8 in/5 to 20 cm from the memory
buttons.
4. Simultaneously press the transmit button of
the hand-held transmitter and the memory
button of the universal remote control.
The LED flashes slowly.
5. Release both buttons when the LED flashes
rapidly.
If

the LED does not flash rapidly after approx.
15 seconds, change the distance and repeat
the step.
The device can be operated using the memory
button with the engine running or the ignition
switched on.
Malfunction
If the device cannot be used after repeated at‐
tempts at programming, please check whether
the hand-held transmitter is equipped with an
alternating code system.

Interior equipment

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
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Closing the windows
Open windows increase air resistance and
therefore lead to greater 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 indi‐
cates 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.
