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
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.
Your responsibility
Your actions have priority at all times. When you
press the accelerator pedal while driving with
active cruise control, the automatic braking
function will be temporarily interrupted. Once
you release the accelerator pedal, the desired
speed or the selected distance to the vehicle
ahead is achieved again.
Do not leave your foot on the accelerator
pedal and make sure that no objects such
as floor mats are lying on the accelerator pedal.
Otherwise the system may not be able to brake
the vehicle.<

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.<

Have the system checked as soon as
possible.

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.
