Heavy rain and also dirt, snow or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper
as well as the bumper area covering the short
range sensors. When doing so, be particularly
careful in removing layers of snow and ice.
Do not apply adhesive labels etc. in the area of
the short-range sensors.
If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be

System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; in complex driving situations; on
curvy, winding roads, slippery roads or roads
with sharp curves such as highway off-ramps;
during inclement weather such as snow, strong
rain or fog; or when entering interchanges, ser-
vice/parking areas or toll booths. It is also
important to regulate your vehicle's speed and
distance setting within applicable legal limits.
Always be ready to take action or apply the
brakes if necessary, especially when the sys-
tem is actively following a vehicle in front of
you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic,
pedestrians or other types of potential traffic
such as a rider on a horseback. It is also possible that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<
The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g. on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle that is actually in
the lane next to yours. Always be ready to take
action or apply the brakes if necessary.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any inter-
ruption, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings.<

fully, e.g. on bridges and sections of road in the
shade, otherwise there is an increased accident
risk.<

Check Control
The concept
The Check Control monitors functions in the
vehicle and issues a message if there is a mal-
function in the monitored systems. This kind of
Check Control message consists of indicator
and warning lamps in the instrument cluster,
and if necessary an acoustic signal and text
messages at the bottom of the Control Display.
Indicator and warning lamps
The indicator and warning lamps can light up in
different combinations and colors. means that a Check Control message has
been generated. The symbol continues to be
visible even when the Check Control message
disappears after a short time. The warning
lamps and text messages are stored and can be
displayed later, also refer to page84.
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.
You can display additional information on most
Check Control messages later, e.g. on the
cause of the malfunction and on corresponding
need for action, see below.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

Depending on your vehicle's equipment, the
stored Check Control messages are also dis-
played with the following symbols:
No malfunctions are present in the moni-
tored systems.
Malfunctions are present in the moni-
tored systems. Depending on the mal-
function, supplementary information is
shown on the Control Display.
The symbols also indicate the status of the ser-
vice requirements display, refer to page81.
Displays after completion of trip
Malfunction reports generated during the trip
are shown consecutively when you switch off
the ignition.
Before the display disappears, you can display
the messages once again. Press the CHECK
button for approx. 2 seconds. If several mes-
sages are present, you can continue to press
the CHECK button to view them in succession.
The display goes out

Speed limit
You can enter a speed and a Check Control
message indicates when you have reached this
speed. This enables you, for example, to
receive warnings if you exceed a speed limit in
an urban area.
You are only warned of reaching this speed a
second time if your vehicle speed falls below it
again by at least 3 mph/5 km/h.

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 sounds 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, oth-
erwise the physical circumstances would mean
that the system warning was too late.<
Automatic activation
The system starts to operate approx. one sec-
ond after you shift into reverse or move the
selector lever into position R with the engine
running or the ignition switched on.
Wait this short time before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
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 remain in front of 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. The setting is stored for
the remote control currently in use.

Malfunction in driving-stability control
systems
The warning lamp for the brake system
lights up, together with the indicator
lamps for ABS, DSC and Tire Pressure
Monitor or Flat Tire Monitor. A mes-
sage appears on the Control Display.
The driving-stability control systems
have failed. Conventional braking effi-
ciency remains available without limita-
tions. While you may continue, you
should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. The Tire Pressure Monitor
or the Flat Tire Monitor is also malfunctioning.
Have the system checked as soon as possible.

malfunction in Canadian models.
The DSC indicator lamp lights up. A
message appears on the Control Dis-
play. A malfunction has occurred in the
DSC and DTC. The stabilizing actions are no longer available. The vehicle remains opera-
tional. Have the system checked as soon as
possible.
The brake system warning lamp lights
up yellow. A message appears on the
Control Display. The brake assistant is
defective. Have the system checked as soon as
possible.

Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. After releasing the footbrake, begin
to drive immediately; otherwise, the starting
assistant no longer holds the vehicle after
approx. 1 second and your vehicle will start to
roll backward.<
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.

Sports Wagon: self-leveling
suspension
Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
is shown on the Control Display. A mal-
function has occurred in the self-leveling sus-
pension. Stop and check the vehicle. If it is con-
siderably lower at the rear than at the front, and
possibly also on one side – rear left compared to
rear right –, go to the nearest BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
ably 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 per-
sonnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it 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.<
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. Do not initialize the sys-
tem when driving with snow chains

pact wheel

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 wheels on page242.
Run-flat tires*
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid severe braking and steering
maneuvers and do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page227, 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
may not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
50 mph/80 km/h or else you run the risk of
causing an accident. In the event of pressure
loss, vehicle handling changes. This includes
reduced tracking stability in braking, extended
braking distance and altered natural steering
characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<
