Changing a wheel 9 Screw in the remaining lug bolts.
Tighten all the bolts securely.
10 Lower the jack and remove it from
beneath the vehicle.
11 Tighten the lug bolts in a diagonal
pattern.
12 Check and correct the tire inflation
pressure at the earliest opportunity.
The vehicle jack is designed for
changing wheels only. Do not at-
tempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 94 ft-lb (130 Nm)] at the earliest
opportunity.<
Store the wheel and the tools in the or-
der opposite that for removal. Be sure
that the jack is first placed back into its
original position.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
The spare wheel has a size
235/65 R 17 tire. If you have
mounted tires on your vehicle with a
different size, have wheels and tires of
the same size and specification rein-
stalled as soon as possible.
When the spare wheel is mounted, the
maximum speed rating is 130 mph
(210 km/h).<

The transmission of power to the four
drive wheels is provided permanently
through a transfer box. The distribution
of torque between the front and rear
axles is 38% to 62%.
Traditional differential locks at the front
and rear axles and in the transfer box
are not required. Their function is taken
over by automatic braking intervention
at all four wheels. These traction inter-
ventions are governed by Automatic
Differential Brake (ADB), a sub-function
of DSC.
If a wheel tends to slip, it is braked
automatically by ADB until it once again
gains traction, and drive force can be
transmitted to that wheel. In addition,
the drive force is distributed to the
remaining wheels during this system
530us133
intervention. Engine output is also re-
duced if necessary.
When the DSC is deactivated, the ADB
traction intervention is set for the maxi-
mum drive force. However, the engine
intervention and the stability controls
are no longer available. For this reason,
DSC should only be deactivated in the
exceptional circumstances described
on page 83.
The BMW X5 is a vehicle for all types of
roads. The permanent four-wheel drive
provides a significant degree of vehicle
stability and tractive power under all
road conditions. It assists in critical sit-
uations such as driving in extreme win-
ter conditions or on bad roads. Precision sensors monitor the wheel
speeds, the steering angle, lateral
acceleration, brake pressure and the
movement of the vehicle around its
vertical axis.
If differences in wheel speeds occur,
the system recognizes the danger of
wheelspin and reduces the engine's
drive torque. If necessary, the system
also responds with additional braking
intervention at all four wheels.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sensor
signals. If discrepancies from this ideal
condition (understeering or oversteer-
ing, for example) occur, DSC stabilizes
the vehicle in fractions of a second by
reducing engine power output and with
the assistance of braking intervention at
individual wheels. Dangerous skids are
thus prevented from the very beginning.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability.
The braking intervention may be ac-
companied by certain sounds specific
to the system.
