DTC is activated.
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.
1. "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.
Malfunction
Malfunctions are displayed via Check Control,
refer to page 76.
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.

Driving stability control systems

1.
Remove the tool mount.
2. Release the wing nut 1.
3. Remove the washer 2 laterally.
4. Remove the compact wheel.
Preparing wheel change
1. Observe the safety precautions above.
2. Loosen the lug bolts a half turn.
Jacking up vehicle
1. Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur‐
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only.
The vehicle jack is designed for changing
wheels
only. Do not attempt to raise another
vehicle model with it or to raise any load of
any kind. To do so could cause accidents
and personal injury.◀ 2.
Guide the jack head into the rectangular re‐
cess of the jacking point when cranking up,
refer to illustration detail. 3.
Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1. Unscrew the lug bolts and remove the
wheel.
2. Remove accumulations of mud or dirt from
the

mounting surfaces of the wheel and hub.
Also clean the lug bolts.
3. Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When

you mount wheels other than Genuine
BMW light-alloy wheels, different lug bolts
may also be required.
4. Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5. Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1. Tighten the lug bolts in a diagonal pattern.
Checking that the lug bolts are tight
To ensure safety, always have the lug
bolts checked with a calibrated torque
wrench as soon as possible to ensure that
they are tightened to the specified torque.
Otherwise, incorrectly tightened lug bolts
are a hidden safety risk. The tightening tor‐
que equals 101 lb ft/140 Nm.

◀ 2.
Stow the defective wheel in the cargo area.
