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 deactivated. You can reactivate the system, if
desired, by tapping or pulling the lever when
road and traffic conditions permit. It is not pos-
sible 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. You can find more information starting on page136.
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. 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.

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 or warning lamps in the
instrument cluster and, in some circumstances,
an acoustic signal.Indicator and warning lamps can light up in both
the indicator area 1 and the display 2 in various
combinations and colors.
What to do in case of a malfunction
The meaning of each lamp in the event of a mal-
function and tips on how to respond are listed
starting on page136.
Hiding Check Control messages
Press the button in the turn indicator stalk.
Some Check Control messages remain visible
until the malfunction in question has been recti-
fied. They cannot be hidden. If several malfunc-
tions occur at the same time, the Check Control
messages are displayed in succession.
Other Check Control messages are automati-
cally hidden after approx. 20 seconds, but
remain stored.

Technology for driving comfort and safety
PDC Park Distance Control*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals 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.
An acoustic warning sounds once an object is
closer than approx. 2 ft/60 cm to the front sen-
sors
* or both rear corner sensors, or closer than
approx. 5 ft/1.50 m to the rear center sensors.
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. 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.
System limitations
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 trailer towbars and couplings,

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 uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Briefly press the button; the DTC indicator
lamps in the instrument cluster come on.
To control
If the indicator lamp flashes:
DTC controls the drive forces and
brake forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
xDrive 325xi, 330xi
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.
Malfunction
In case of any of the malfunctions
described below, drive cautiously and
think well ahead. Avoid driving on rough tracks
and pressing the accelerator pedal down to full
throttle or kick-down position, otherwise the
drive system could be damaged or accidents
could result.<

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.
