Controls
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
recognize 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. <

Technology for driving comfort and safety
Controls
xDrive
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.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
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 is available for activation at vehicle speeds
below approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 miles or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or decreasing speed
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range of between approx. 3 mph/5 km/h and
20 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.

To increase speed
2 To decrease speed
Activating HDC
Press the button; the LED lights up.
When the vehicle is being braked automatically,
the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
over approx. 40 mph or 60 km/h.
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.

Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable due to exces-
sive brake temperature, or DSC has failed.
