Tire Pressure Monitor TPM*
The concept
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
For operating principle refer to page59.
1.Start the engine, but do not start driving.
2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the corre-sponding symbol appears in the display
accompanied by the word "RESET".
3.Press button 2 to confirm your choice of the
Tire Pressure Monitor. The following dis-
play appears:
4.Press button 2 for approx. 5 seconds, until
the reading shown below is displayed:
5.Start to drive.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the
target values to be monitored. The system
reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, the reset is continued automati-
cally. The indicator lamp goes out after the
system reset is completed.

Wheels and tires

Tire age
For various reasons, such as the development
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of
the actual wear of the tires.
The manufacturing date of tires is contained in
the tire coding:
DOT ... 3408 means that the tire was manufac-
tured in week 34 of 2008.
Run-Flat Tires
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall.
Run-Flat Tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls ensures that the tire can
continue to be used subject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire on page67.
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.<
Retreaded tires
BMW recommends that you do not use
retreaded tires, since driving safety may be impaired. The causes for this include poten-
tially different tire casing structures and often
wide variations in tire age, which can result in a
limited service life.<
Correct wheels and tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you.
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions, which could
lead to body contact and thus to severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot guarantee their driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS, DSC or
FTM.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
When mounting new tires or changing over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise the
Tire Pressure Monitor may not be able to detect
a puncture, refer to page69. Your BMW center
will be glad to advise you.

Replacing components
128 When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page112.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page131.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page62.
>Radio
Stations must be stored again, refer to the
separate Owner's Manual for Radio.
>Glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Seat and mirror memory
*
The positions must be stored again, refer to
page39.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page88.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, oth-
erwise this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
In the glove compartment
Accessing the fuse box:
1.Open the glove compartment.
2.Remove the damper, arrow1, from the
lower holder by applying forward pressure.
