Changing a wheel9 Position the new wheel or the
space-saver spare tire on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10 Screw in the remaining lug bolts.
Tighten all the bolts securely
11 Lower the jack and remove it from
beneath the vehicle
12 Tighten the lug bolts in a diagonal
pattern462de267
13 Wheels with full wheel covers
*:
Position the wheel cover with the
valve opening over the valve (arrow)
and press it onto the wheel with
both hands
14 Check and correct the tire's inflation
pressure at the earliest possibility.
For vehicles with RDC (Tire Pres-
sure Control):
Reactivate the system after
mounting the spare wheel or
correcting the inflation pressure.
Refer to page 86.
Use original BMW full wheel
covers only. Other wheel covers
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire, since this could
damage the cover.<

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.
Have the lug bolts checked for proper
tightness with a calibrated torque
wrench at the earliest possibility [torque
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, be sure that
you do not damage the retaining pin in
the spare tire recess.
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 quickly as
possible and have the new wheel
balanced.

ASC+T/DSC
*
Highly sensitive sensors monitor the
number of revolutions of the wheels.
When equipped with DSC, they also
monitor steering angle, lateral accelera-
tion, brake pressure and the movement
of the vehicle around its vertical axis.
If differences in the wheel speeds occur,
ASC+T counteracts the danger of
wheelspin by reducing engine torque; if
necessary, ASC will also respond by
applying the brakes to the rear wheels.
In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor's
signals. If deviations from this occur
(understeering or oversteering, for
instance), DSC can stabilize the vehicle
in fractions of a second by reducing
engine output and with the assistance of
braking intervention at individual
wheels. As a result, dangerous skids can
be prevented even as they are just
beginning, but only within the laws of
physics.
You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and driving stability.
The braking intervention may be
accompanied by sounds specific to the
system.

Four-wheel driveThe 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-X), a sub-func-
tion of DSC.
If a wheel tends to slip, it is braked
automatically by ADB-X 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 530us133
system intervention. Engine output is
also reduced if necessary.
When the DSC is deactivated, the
ADB-X traction intervention is set for
the maximum drive force. However, the
engine intervention and the stability
controls are no longer available. For
this reason, DSC should only be deacti-
vated in the exceptional circumstances
described on page 84.
The BMW 325xi and 330xi are not
intended for off-road operation. But the
permanent four-wheel drive provides a
high degree of driving stability and trac-
tion on all road conditions and surfaces.
It supports you in critical driving condi-
tions, e.g. in extreme winter conditions
or on loose road surfaces.
