priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.<
Things to know about active cruise control
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; heavy traffic such as during rush hour; 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 inter-
changes, service/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 system is actively following a vehicle in front
of you.<

Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react
to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically 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 alert-
ness.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
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 actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission to neutral/N, or
deactivates DSC. After any deactivation, the
system will no longer automatically activate the
vehicle brakes, which means the driver must intervene and resume manual braking. You
should then reactivate the system only when
you are fully aware of the prior speed and dis-
tance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.
In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.

System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected.The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with thin and wedge-shaped
objects, etc. Low objects already displayed, e. g. a curb, can also disappear from the detec-
tion area of the sensors again before a continu-
ous tone sounds. Loud noises from outside and
inside your vehicle may prevent you from hear-
ing the PDC signal tone.<
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away from
the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Safe braking, refer to page107.
CBC Cornering Brake Control
When braking during curves or when braking
during a gear change, driving stability and
steering response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the brake application. When
the brake pedal is released, DBC is deactivated.

78
DSC Dynamic Stability Control
The system prevents traction loss in the driving
wheels when starting off and accelerating. DSC
also detects unstable driving conditions such
as a fishtailing rear end or sliding of the front
wheels. In these cases, DSC helps the vehicle
maintain a safe course within physical limits by
reducing engine output and through braking
actions in the individual wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<
DTC Dynamic Traction Control
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button briefly; the DTC indicator lamp
in the instrument cluster lights up.
Deactivating DTC again
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Deactivating DTC and DSC together
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not longer
than approx. 10 seconds. Stabilizing and drive
output promoting actions are no longer exe-
cuted. In addition, the stability promoting inter-
vention of the active steering is deactivated,
refer to page81.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.
Reactivating DSC
Press the button; the DTC indicator lamp in the
instrument cluster goes out.

Malfunction in vehicle stability-control
systems
The brake system warning lamp lights
up in red, appearing together with the
indicator lamps for ABS and DSC. A
message appears on the Control Dis-
play. The driving stability control sys-
tems are deactivated. Conventional
braking efficiency remains available
without limitations. While you may con-
tinue, you should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. Have the system checked
as soon as possible.

malfunction on Canadian models.
The indicator lamp for DSC lights up; a
message appears on the Control Dis-
play. DSC and DTC are deactivated.
The stability maintenance functions are no
longer available. The vehicle remains in running
order. Have the system checked as soon as
possible.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem 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 and a mes-
sage appears on the Control Display.
There is a malfunction in the system.
Have the system checked as soon as possible.
If there is a malfunction in the system,
please remember to adapt your speed
accordingly, especially in curves. The suspen-
s i o n w il l b e n o t i c ea b ly s o f t e r a n d t h e v e h i cl e w il l
display a greater tendency to tilt during corner-
ing and in crosswinds. If a message stating that
you should stop appears on the Control Display,
stop and switch off the engine as soon as pos-
sible. 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. Contact your BMW cen-
ter.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion 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.
Perform the initialization immediately
after correcting the inflation pressure,

Technology for comfort, convenience and safety
80 after changing a tire or after changing a wheel or
all of the wheels.<
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 initial-
ize the system.<
Control Center, for principle details, refer to
page16.
1.Open the menu.
2.Select "Vehicle settings" and press the
controller.
3.Select "FTM" and press the controller.
4.Start engine, but do not start driving.5.Select "Set tire pressure" and press the
controller.
6.Select "Yes" and press the controller.
7.Start to drive.
The message "Initializing" is displayed.
The initialization finishes during driving. Then
the message "Status: Active" appears on the
Control Display again.
Indication of a flat tire
The warning lamp lights up in red and a
message appears on the Control Dis-
play. 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 page185.
Vehicles with run-flat tires
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steering
maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page174, 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
has not been initialized. The system must
then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, or obvious tire damage, you can
estimate the possible distance for contin-
ued 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, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. 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 occur while the vehicle is
being driven, this can indicate final failure of the
damaged tire. Reduce speed and stop as soon
as possible. Do not continue driving. Contact
your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page78.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speeds, greater steering wheel move-
ments are required, whereas at higher speeds,
the vehicle reacts more sensitively to steering
wheel movements. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Initializing system
1.Start the engine.
2.With the vehicle stationary, turn the steer-
ing wheel from the straight-ahead position
t o t h e le f t a s f a r a s i t w i ll g o a n d t h e n b a c k t o
the straight-ahead position.
3.Switch off the engine.
When you start the engine again, all the func-
tions of the active steering are available once
again.
