Tire Pressure Control (RDC)
*
Flat tireIf there is a tire failure with a loss of air
pressure, the red indicator lamp comes
on or the message "TIRE DEFECT" ap-
pears in the Check Control. In addition,
a gong sounds.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a safe
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The spare tire which is available in
your vehicle as standard equip-
ment is equipped with the electronics
required for RDC and, following activa-
tion of the system, is also monitored af-
ter it is mounted.<
The RDC cannot alert you to se-
vere and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceDuring the period of the malfunction,
the yellow indicator lamp comes on
or the message "TIRE CONTROL
INACTIVE" appears in the Check
Control.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire,
additional wheels with RDC
electronics are on board.
Please contact your authorized BMW
center for additional information.

Changing tires
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat,
surface. Switch on the hazard flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse (selector lever in Park with
automatic transmission) and engage the
parking brake. All passengers should
be outside the car and well away from
your immediate working area (behind a
guardrail, for instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the car on a soft or slippery sup-
port surface (snow, ice, loose gravel,
etc.), since it could slide sideways.
Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack Ð risk of fatal injury.<
What you will needIn order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Car jack
sedan: Fold back the luggage com-
partment floor mat for access, then
unscrew the wingnut to release the
jack (arrow).
sport wagon: Raise the floor panel
and spare tire cover (refer to
page 118).
When you have completed work,
screw the jack all the way back down.
Fold the handle back and insert it in
its holder
>Wedge (wheel chock)

Procedure1 Read carefully and comply with the
safety precautions on the previous
page.
2 Secure the vehicle against 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 se-
curely in front of the tire. If the
wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure the
vehicle from rolling.
3 Wheels with full wheel covers
*:
Reach into the ventilation openings
and pull the cover off.
4 Wheels with adapter
*: Position the
lug bolt adapter on the lug bolt
cover. Then apply the lug wrench
and turn it to the left (refer to the
illustration).
380de092
5 Wheels with hub cover
*: Pry the
hub cover off with the screwdriver in
the slot.
6 Loosen the lug bolts 1/2-turn.
7 Position the jack at the jacking point
closest to the flat tire 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.
8 Jack the car up until the wheel you
are changing is raised from the
ground.
9 Unscrew the lug bolts and remove
the wheel.

dirt from the mounting surfaces of

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.
