Indicator and warning lamps
The concept
Indicator and warning lamps can light up both in
the display area1 and in the display2 in various
combinations and colors.
Some lights are tested for proper function by
briefly lighting up during starting of the engine
or when the ignition is switched on.
Explanatory text messages
Text message at the bottom edge of the Con-
trol Display explain the meaning of the dis-
played indicator and warning lamps.
Additional information, e.g. on the cause of a
malfunction and on the corresponding need to
take action can be displayed via the Check Con-
trol, refer to page77.In the case of corresponding urgency, this infor-
mation is displayed immediately when the
related lamp lights up.

Outside temperature warning
If the display drops to +377/+36, a signal
sounds and a warning lamp lights up. There is
an increased danger of ice.
Even at temperatures above +377/
+36 ice can form. Therefore, drive care-
fully, e.g. on bridges and sections of road in the
shade, otherwise there is an increased accident
risk.<
Tachometer
The white-striped advance warning field,
arrow1, changes depending on the engine
temperature. With increasing engine tempera-
ture the advance warning field becomes corre-
spondingly smaller. Avoid allowing the engine
speed to rise as far as the orange warning sec-
tor whenever possible.
Be sure to avoid engine speeds in the red warn-
ing field, arrow2. In this range, the fuel supply is
interrupted to protect the engine.
Coolant temperature
Should the coolant, and with it the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page199.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sound for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1,50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
otherwise the physical circumstances would
mean that the system warning was too late.<
Automatically activating
The system starts to operate automatically
approx. 1 second after you select reverse gear
or move the selector lever into the R position
with the engine running or the ignition switched
on.
Wait this short period before driving.
Manual activation
Press button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc. As the distance between
vehicle and object decreases, the intervals
between the tones become shorter. If the dis-
tance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you stop before an object that was only
detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.
PDC with visual warning*
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are already shown there before
a signal tone sounds.

Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system.
Do not continue driving, but instead contact
your BMW center.<
Sports Wagon: self-leveling
suspension
Malfunction
The warning lamp for the self-leveling
suspension lights up in yellow and a
message appears on the Control Dis-
play. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possible also on one side – rear
left compared to rear right –, go to the nearest
BMW center or a workshop that works accord-
ing to BMW repair procedures with correspond-
ingly trained personnel. Drive with appropriate
caution in the meantime. The vehicle has
reduced ground clearance and driving comfort
may be noticeably reduced. Even if the position
of the vehicle is normal, go to the nearest BMW
center or a workshop that works according to
BMW repair procedures with correspondingly
trained personnel.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<

Technology for comfort, convenience and safety
88
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. When driving with snow
chains
* or with the compact wheel*, do not
initialize the system.<
iDrive, for principle details, refer to page16.

controller.7.Select "Yes" and press the controller.
8.Start to drive.
The message "Initializing..." is displayed.
The initialization finishes during driving. Then
the message "Status: FTM active" appears on
the Control Display again.
Indication of a flat tire
The warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact a BMW center.<
3.Replace the damaged wheel, refer to
Changing a wheel on page207.
Run-flat tires*
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page194, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor

The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.
With the daytime driving lamps
* activated, the
low beams are always switched on when the
ignition is switched on.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In the switch position1, the Adaptive Head
Light is active and the automatic headlamp con-
trol
* is switched on.
To avoid dazzling oncoming traffic, the Adap-
tive Head Light is not active when driving in
reverse and points toward the passenger side
when the vehicle is stopped.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not switch them on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the inside rearview mirror controls the process.
The assistant ensures that the high beams are
switched on whenever the traffic situation
allows. This reduces the strain on you while at
the same time providing you with the best pos-
sible visibility. Of course, you can intervene at
any time and switch the high beams on and off
in the accustomed manner.

The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.
You can operate the system when the engine is
running or when the ignition is switched on.
If the device can not be used after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions for the original hand-held transmit-
ter or hold down the programmed memory
button1 of the integrated universal remote
control. If the LED 2 on the integrated universal
remote control flashes rapidly for a short time
and then remains lit for approx. 2 seconds, this
indicates that the original hand-held transmitter
uses an alternating-code system. In the case of
an alternating-code system, program the mem-
ory buttons1 as described at Alternating-code
transmitters.<
Alternating-code transmitters
To program the integrated universal remote
control, consult the operating instructions for
the equipment to be set. You will find informa-
tion there on the possibilities for synchroniza-
tion.

Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. Not all commercially available additives are
suitable for your BMW. Ask your BMW center
for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunctions
Brake fluid
The warning lamp lights up in spite of
the handbrake being released; a mes-
sage appears on the Control Display:
stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system thoroughly
checked.
Display of the previously described
malfunction on Canadian models.
When you continue driving, an increased
brake pedal path can be necessary, and
significantly longer braking distances might be
required. Please adapt your driving style
accordingly.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring led to serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can close when
fuel vapor escapes. Then a display light up. If
the cap is then tightened, the display will go out
within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain

Xenon lamps*
The service life of these bulbs is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times.In the unlikely event that one of
these lamps should fail, you can respond by
switching on your fog lamps and proceeding
carefully in accordance with the reduced visibil-
ity, where allowed by law.
Have work on the Xenon lighting system
performed only by your BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high voltage present in the
