Use good judgement to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, you may be in violation of the law or
an accident could result.<
Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays in the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When the speed is reduced to below
20 mph or 30 km/h due to a traffic situation
>When you switch gears very slowly or shift
to idle in cars with manual transmission
>When you select the automatic transmis-
sion's/SMG's neutral position N
>When you activate the Dynamic Traction
Control DTC
>When you deactivate the Dynamic Stability
Control DSC
>When DSC or ABS is intervening
>When the system does not recognize any
objects for a longer period of time, e.g. on infrequently traveled roads without a shoul-
der or guard rails, or if the radar sensor is
covered with dirt, refer to page66
>When you apply the handbrake
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary, otherwise there is a
risk of accident.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated due to a driving
speed below 20 mph or 30 km/h, an application
of the handbrake or a DSC intervention. A mes-
sage appears on the Control Display.
Resuming stored desired speed and
distance
Briefly press the button, arrow 4.
The stored speed and distance are regained
and maintained.
In the following instances, the stored speed is
deleted and can no longer be resumed:
>When driving stability control systems are
intervening
>In cars with manual transmission: when you
shift gears very slowly or shift to idle posi-
tion
>With automatic transmission/SMG: when
you engage selector lever position N
>When the ignition is switched off

in the instrument cluster display, it is pos-
sible that the system prerequisites for operation
are currently not met. Calling up Check Control
messages, refer to page80.<
Warning lamps
The indicator2 flashes in red; a
signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to
the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
active cruise control are not met,
e.g. as a result of ABS or DSC interventions. Active cruise control is deacti-
vated. You can reactivate the system, if desired,
by tapping or pulling the lever when road and
traffic conditions permit. It is not possible to
resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bumper, see arrow. Be sure
to use particular care when removing any layers
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page79.
System limitations
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.<
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
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.
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when a much slower vehicle cuts in front of you at
close range.<
Active cruise control can only decelerate the
vehicle to approx. 20 mph or 30 km/h.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to maintain the selected distance automatically.
This also applies to great differences in speed
between you and vehicles ahead, e.g. when
quickly approaching a truck. There is a risk of
collision. Once the system has established that
a vehicle is indeed in front of you, it will indicate
that you must brake and/or maneuver the vehi-
cle yourself. Take action yourself, otherwise
there is a risk of an accident.<
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

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. Such a Check Control mes-
sage includes indicator and warning lamps in
the instrument cluster and, in some circum-
stances, an acoustic signal as well as text mes-
sages at the bottom of the Control Display.
Indicator and warning lamps
Indicator and warning lamps can light up in both
the indicator area 1 and the display 2 in various
combinations and colors.
Explanatory text messages
Text mess ages at the lo wer edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
For most Check Control messages, you can
view more information later, e.g. regarding the
cause of a malfunction and how to respond,
refer to page80.
In urgent cases, this information will be shown
immediately as soon as the corresponding lamp
comes on.

Technology for driving comfort and safety
PDC Park Distance Control*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
in front of
* or behind your car. To measure the
distance, there are four ultrasonic sensors in
each bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 2 ft/60 cm from
the front sensors
* or both rear corner sensors,
or approx. 5 ft/1.50 m from the rear center sen-
sors.
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 physical circumstances may lead to the
system warning being issued too late.<
Automatic mode
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.
Switching on manually
Press the button, the LED lights up.
Switching off manually
Press the button again; the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 165 ft/50 m or
exceeds a speed of approx. 20 mph or 30 km/h;
the LED goes out. You can reactivate the sys-
tem as needed.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, the tone sounds at the rear if the system
detects an object behind the car. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
The warning signal is canceled after approx.
3 seconds, if you are moving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
Manual mode
The LED above the button flashes in addition.
PDC with optical warning
You can also have the system show distances
to objects on the Control Display. The contours
of distant objects are shown on the Control Dis-
play even before the acoustic signal sounds.

Hill Descent Control HDC 325xi, 330xi
HDC is a downhill driving assistant that reduces
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or decreasing speed
By accelerating or braking you can change the
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range using the cruise control stalk.

Activating HDC
Press the button; the indicator lamp lights up.
The indicator lamp flashes when the vehicle is
being braked automatically.
Deactivating HDC
Press the button again; the indicator lamp goes
out.
HDC is deactivated instantly above a speed of
approx. 35 mph or 60 km/h, or approx.
10 seconds after the ignition is switched off.
Using HDC
In cars with manual transmission:
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.

Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.<

Malfunction
The warning lamps for the brake sys-
tem light up in yellow. The drive-off
assistant has failed. The car will not
be held in place after the brake is
released. Have the system checked as soon as
possible.
Canadian models display these warn-
ing lamps.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. 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 system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration>If snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
