xDrive

xDrive is the all-wheel-drive system of your ve‐
hicle. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv‐
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to the
front and rear axle depending on the driving sit‐
uation and prevailing road conditions.

Dynamic Performance

Control*

The concept

Dynamic Performance Control optimizes the
handling characteristics of your vehicle when
starting off, cornering, and during evasive ma‐
neuvers.
To achieve this, the system variably distributes
the drive torque of the rear axle to the two rear
wheels. This further increases the steering pre‐
cision and tracking stability of your vehicle.

Display

The Control Display shows how xDrive and Dy‐
namic Performance Control are distributing the
drive forces.

"Vehicle Info"

2.

"Torque distribution"

The current distribution of drive forces is indi‐
cated by arrows pointing to all four wheels.
The highlighted arrows show the drive forces
currently present. The longer an arrow is, the
greater the drive forces in the associated wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.

Hill Descent Control HDC

The concept

HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. The vehicle moves at approxi‐
mately walking speed without braking
intervention by the driver.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
moving downhill at speeds below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approximately walking speed, approx. 5 mph/
8 km/h and keeps it constant.
Only use HDC in transmission positions D or R.

Increasing or reducing speed

The speed can be changed in the range from
approx. 4 mph/6 km/h to approx. 15 mph/25 km/
h by pressing the accelerator or brake pedal
lightly.
