Tire Pressure Control (RDC)
*
Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic sig-
nal is sounded.
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 space-saver spare tire
* is
provided for temporary use only in
the event of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
* that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will be also be monitored once the
tires have been mounted and the sys-
tem activated.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.<
System interferenceThe RDC system may be interrupted
temporarily by other systems or devices
that use the same radio frequency.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Tire replacement Tire rotation
Do not use retreaded tires. Driving
safety may be impaired by their
use. This is due to the possible varia-
tions in casing structures and, in some
cases, to their extreme age, factors that
can lead to a decrease in their durabil-
ity.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 329 indicates that the tire was
manufactured in Week 32 of 1999.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.
Spare tires over 6 years old should be
used only in case of emergency. A tire
in this condition should be replaced by
a new tire immediately, and should not
be mounted together with new tires.
Between the axlesThe tread wear patterns at the front end
differ from those at the rear Ð the actual
patterns will vary according to individ-
ual driving conditions. In the interests of
safety and maintaining optimal handling
characteristics, tire rotation is not rec-
ommended.
If a proposed interaxle rotation of tires
is based on economic considerations,
one should consider whether the costs
for the rotation are likely to be recap-
tured by any increase in the service life
of the tires that might be realized. In
principle, interaxle rotation should be
performed in short intervals, with a
maximum of 3,000 miles (5,000 km).
Consult your BMW center for more
information.
Should you decide to rotate the tires, it
is essential to comply with the following:
Rotate tires on the same side only, since
braking characteristics and road grip
could otherwise be adversely affected.
Following rotation, the tire inflation
pressure should always be corrected.If different tire sizes are mounted
on the front and rear axles (refer to
page 118), the wheels may not be ro-
tated from one axle to the other.<

Wheel and tire combinations The right choice Use only BMW-approved tires. Refer to
page 118.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory. Con-
sult any BMW center for details. Com-
ply with local/national regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and DSC. The function of
these systems is impaired if improper
wheel-tire combinations are used.
For this reason, use only tires of the
same brand and tread pattern. In the
event of a flat tire, for example, remount
the approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
The codes on radial tires:
The speed rating indicates the approved
maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = above 167 mph (270 km/h)
ZR = above 150 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Radial tire ID code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
205/60 R
1591W
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect tire valve from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. Example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches

Changing a wheel Battery Driving with the space-saver
spare tire
*
Drive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire with the same
size and specifications as the others at
the earliest possible opportunity. Main-
tain correct tire pressures. Refer to
page 28.<
Battery locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41). Use a screwdriver or a coin
to loosen the two fasteners in the illus-
tration 1/4-turn. Loosen the third fas-
tener in the upper-center side trim
panel. Remove the fasteners. In order
to remove the storage tray, slide the
side trim panel slightly upward.460de176
Charge conditionThe "Magic Eye
*" is a hydrometer that
allows you to read the charge condition
of the battery:
>Green: adequate charge.
>Black: not adequately charged. The
battery must be recharged. Please
contact your BMW center for addi-
tional information.
>Yellow: Replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<
