Tire pressure reset BMW M3 COUPE 2008 E92 Owner's Manual

Technology for driving comfort and safety
70 When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
1.Start the engine, but do not start driving.
2.Press the button for approx. 4 seconds until
the warning lamp in the instrument cluster
lights up yellow. Warning lamp, refer to Indi-
cation of a flat tire on page70.
3.Start to drive.
Initialization is completed while the car is
moving, without any feedback.
Indication of a flat tire
The warning lamps come on in yellow
and red. In addition, an acoustic sig-
nal sounds. There is a flat tire or sub-
stantial loss of tire pressure.
1.Reduce your speed and carefully stop the
car. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged tire. To do so, check
the tire pressure using the M Mobility Sys-
tem, refer to Producing the tire inflation
pressure on page132.
3.Repair the flat tire with the M Mobility Sys-
tem, refer to page132.
Malfunction
The warning lamps come on in yel-
low. The Flat Tire Monitor has a mal-
function or has failed. Have the sys-
tem checked as soon as possible.
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 has been
mounted, or if TPM is temporarily malfunction-
ing due to other systems or devices using the
same radio frequency.
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
1.Start the engine, but do not start driving.
2.Press the button for approx. 4 seconds until
the warning lamp in the instrument cluster
lights up yellow. Warning lamp, refer to

Message for low tire inflation pressure on
page71.
3.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.
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or substantial loss
of tire pressure.
1.Reduce your speed and carefully stop the
car. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged tire or tires. To do so,
check the tire pressure using the M Mobility
System, refer to Producing the tire inflation
pressure on page132.
If it is not possible to make an identifi-
cation, contact your BMW center.<
3.Repair the flat tire with the M Mobility Sys-
tem, refer to page131.
Have the tire replaced by a BMW center or a
workshop that is informed in the handling of
TPM and that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. No punctures can be
detected.
This type of message is shown in the following
situations:
>If there is a malfunction
Have the system checked.
>If a wheel without TPM electronics has
been mounted
>If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.
Message for unsuccessful system
reset
The warning lamp lights up yellow.
The system is not reset after a tire
has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page70.
Declaration according to NHTSA/
FMVSS 138
Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-

Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Checking pressure
Only check tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive on
a flat tire. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page69, or reset the Tire Pressure Monitor,
refer to page70.<
Inflation pressure specifications
The table below provides all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:
>Tire sizes for your vehicle>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following page in the col-
umns for traveling speeds up to a maximum of
100mph or 160km/h.
These tire inflation pressures can also be found
on the driver's-side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed, otherwise
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following page in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise tire
damage and accidents could occur.<
Observe all national and local maximum speed
limits, otherwise violations of the laws could
occur.
