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.
Start engine, but do not begin to drive.
2.
Press the button until the yellow warning 
lamp in the instrument cluster lights up for a 
few seconds.
3.
Begin driving.
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.

Check tire inflation pressure and correct as 
needed.
