Changing a wheel>Space-saver spare tire
Next to the jack.
Loosen the wing nut (arrow) by hand,
remove the storage shelf and take the
wheel out.
>Lug wrench Ð in the onboard tool kit
on the underside of the luggage
compartment lid (refer to page 166).46cde039
Procedure1 Read and comply with the safety
precautions provided on the
previous page.
2 Secure the vehicle from rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If
the vehicle is parked on a down-
ward slope, place the wedge
securely in front of this tire. If the
wheel must be changed on a
surface with a more severe slope,
take additional precautions to
secure the vehicle from rolling.
3 If your wheels are equipped with full
wheel covers
*: reach into the venti-
lation openings and pull the cover
off.
46cde055
4 Loosen the lug bolts with a g turn.
5 Position the jack at the jacking point
closest to the flat tire (refer to the
center illustration) so that the jack
base is vertically below the jacking
point and the entire surface of the
head of the jack will move into the
square recess of the jacking point
(refer to the illustration detail) when
the jack is cranked.
6 Crank the vehicle up until the wheel
in question is raised from the
ground.
7 Unscrew the lug bolts and remove
the wheel.
8 Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub; clean the lug
bolts.462de252

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
pattern.462de266
13 If your wheels are equipped 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 Tire
Pressure Control (RDC):
Reactivate the system after
mounting the space-saver spare tire
or after correcting the air pressure.
Refer to page 91.
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire since this could
damage the cover.<
462de279
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.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench [torque specifi-
cation: 72 lb.ft (100Nm)] at the earliest
opportunity.<
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 soon as
possible and have the new wheel/tire
balanced.

Deceleration sensors continuously
monitor the acceleration forces acting
upon the vehicle. If, as the result of a
frontal collision, a deceleration is
reached at which the protection of the
safety belts alone is no longer
adequate, the gas generators of the
driver and passenger-front airbags are
ignited. However, the passenger-side
airbag is only triggered if an additional
sensor has recognized that the
passenger seat is occupied.
In the event of a side collision, the side
airbags in the front and/or rear
* are
triggered if necessary.
390de012
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is accompa-
nied by a certain amount of ignition and
inflation noise, which will be drowned
out by the noise from the accident
itself. The gas required to inflate the
airbags is not dangerous, and the
associated smoke then dissipates.
The entire process is completed within
fractions of a second.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+T will also
respond by applying the brakes to the
rear wheels.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion 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. Dangerous skids are
thus prevented before they can even
start, and all of this is possible, of
course, only within physically possible
limits. You may need some time to
become accustomed to the system's
intervention. However, it provides
optimum drive force and vehicle
stability. The braking intervention may
be accompanied by sounds specific to
the system.
