Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.
<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.
<
The system does not function properly if it has
not been reset, e.g. it may identify a tire as flat in
spite of the fact that the tire is filled to the cor-
rect inflation pressure.
The system is deactivated and is unable to
detect flat tires if a wheel not equipped with
TPM electronics has been mounted, e.g. a
compact wheel, or if TPM is experiencing tem-
porary interference from other systems or
devices that use the same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.
<
1.

After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.
Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.
Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.
<
3.
Replace the damaged wheel, refer to
Wheel changes on page
115
.
4.
Check tire inflation pressure and correct as
needed.
The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.
