Changing tires
the wheel and hub. Clean the lug
bolts.
11 Position the spare wheel. Secure
the wheel by turning at least two lug
bolts into opposite bolt holes.
12 Screw in the remaining lug bolts.
Tighten all the bolts securely.
13 Lower the jack and remove it from
beneath the car.
14 Tighten the lug bolts in a diagonal
pattern.
15 Wheels with full wheel covers: Place
the wheel cover with the valve
opening over the valve (arrow). Use
both hands to press the cover se-
curely onto the rim.
For this light-weight wheel, use
only the full wheel cover installed 390de360
by the factory. Other wheel covers may
not fit securely.<
16 Wheels with hub covers:
Position the hub cover and press it
on tightly.
17 If equipped with lug bolt covers:
Align the arrow on the cover with
the line in the wheel and press the
cover into place.
18 Check and correct the air pressure
at the earliest opportunity.
For vehicles with Tire Pressure Con-
trol (RDC)
*:
After mounting the spare tire or cor-
recting the inflation pressure, reacti-
vate the system. Refer to page 92.The vehicle jack is designed for
changing tires 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.
To ensure continued safety, have the
lug bolts checked with a calibrated
torque wrench [torque specification
72 lb-ft (100 Nm)] at the earliest
opportunity.<
When storing the wheel, take care to
ensure 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 soon as
possible and have the new wheel/tire
balanced.

In order to take driving conditions into
account, ATC registers corners and
both uphill and downhill gradients. For
example, if you maintain speed through
a curve, the transmission does not up-
shift.
On uphill gradients, it shifts only when
the engine speed increases in order to
make more efficient use of power
reserves. On downhill gradients ATC
downshifts when the speed of the vehi-
cles increases, causing the driver to
step on the brakes.Precision sensors monitor the number
of revolutions of the wheels. When
equipped with DSC, they also monitor
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
If differences in the wheel speeds
occur, the system counteracts the dan-
ger of wheelspin by reducing torque. If
necessary, the system also responds
with additional applications of the
brakes at the rear wheels.
If the system detects an instability in the
vehicle's condition, the braking action
can also be directed to help the front
wheels by the DSC in order to help sta-
bilize the vehicle.
You may need some time to become
accustomed to this system intervention.
However, it guarantees optimum drive
force and driving stability.
The braking intervention may be
accompanied by a certain degree of
noise.ATC
