Driving stability control systems
CONTROLS
Hill Descent Control provides assistance when
driving in selector lever positions D, N, and R.
Display in the instrument cluster
If drive-off support is activated, the
drive-off support indicator light illumi-
nates on the instrument cluster.
Enabling/disabling Hill Descent
Control
To activate/deactivate Hill Descent Control,
go through the menu as follows: Apps

Assistance" / "Hill Descent Control".
BMW xDrive
BMW xDrive is the all-wheel-drive system
of the vehicle. The interplay between BMW
xDrive and other suspension control systems
such as Dynamic Stability Control further opti-
mizes traction and driving dynamics.
Hill Descent Control is automatically disabled
at speeds above approx. 25 mph/40 km/h.
While Hill Descent Control is regulating the ve-
hicle speed, the following functions are deacti-
vated:
BMW xDrive variably distributes the drive
forces to the front and rear axles as required
by the driving situation and road conditions.

Hill Descent Control is a downhill control fea-
ture for vehicles with all-wheel drive. This fea-
ture adjusts the vehicle speed on steep down-
hill gradients, e.g., when driving on unpaved
roads.
Display in the instrument cluster
The set speed is displayed on
the instrument cluster together
with the indicator light for Hill
Descent Control.
When Hill Descent Control is on, the vehicle
moves at the speed set by the driver, without
the driver having to depress the brake pedal.
▷
The display illuminates green
when the system is on. Hill
Descent Control decelerates
the vehicle.
While Hill Descent Control is regulating the
speed, it automatically distributes the brake
power to the individual wheels. Driving stability
and steerability are improved. If necessary, the
Antilock Braking System prevents the wheels
from locking.
▷
The display illuminates gray when the sys-
tem is in standby.
Hill Descent Control can be enabled at speeds
below approx. 25 mph/40 km/h.
Display in the Head-up display
The status of Hill Descent Control can also be
shown on the Head-up display.
Speeds can be set between approx.
2 mph/3 km/h and approx. 20 mph/30 km/h.
While driving downhill, this system reduces the
vehicle speed to the set value, as physically
possible.
