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 page
132
.
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 page

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 page
70

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-
