xDrive on 525xi, 530xi
xDrive is the 4-wheel drive system of your
BMW. 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 torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control on 525xi,
530xi
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately twice walking speed without
active intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately double
walking speed, approx. 7 mph/12 km/h, and
then maintains this speed at a constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.
Activating HDC
You can activate HDC:
>with the programmable buttons on the
steering wheel, refer to page53
>using iDrive

the controller.
6.Select "HDC on" and press the controller.
HDC is shown in the instrument cluster.
If the vehicle is automatically braked, a message
is displayed on the Control Display for approx.
20 seconds.
Deactivating HDC
When you use the programmable buttons on
the steering wheel or via iDrive, the HDC display
goes out.
HDC is automatically deactivated in the follow-
ing situations:
>Above approx. 37 mph/60 km/h
>After switching off the ignition

Replacing components
228
Compact wheel*
1.Unscrew the wing nut 1.
2.Remove the washer 2 laterally.
3.Take out the tool mounts 3.
4.Remove the compact wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Prevent the vehicle from rolling:
Place the chock behind the front wheel on
the other side of the vehicle, or on inclines,
in front of this wheel. On a steep grade, take
other steps to prevent the vehicle from roll-
ing.
3.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. 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
recess 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 Genu-
ine 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.
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 speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3.Check and correct the tire inflation pressure
at the earliest opportunity.

seal caps against dirt and contamina-
