Have the damaged tire replaced by your BMW 
Sports Activity Vehicle Center or a workshop 
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using 
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and 
then lights up continuously. Flat tires 
cannot be detected.
Such a message is displayed in the following 
situations:
>
When a malfunction is occurring:
Have the system checked
>
When a wheel without TPM electronics is 
mounted, e.g. a compact wheel
>
When TPM is experiencing temporary inter-
ference from other systems or devices that 
use the same frequency
NHTSA/FMVSS-required explanation 
of 138 Tire Pressure Monitoring 
System
Each tire, including the spare, should be 
checked monthly when cold and inflated to the 
inflation pressure recommended by the vehicle 
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a 
different size than the size indicated on the 
vehicle placard or tire inflation pressure label, 
then you should determine the proper tire infla-
tion pressure for those tires. As an added safety 
feature, your vehicle has been equipped with a 
tire pressure monitoring system, TPMS, that 
illuminates a low tire pressure warning lamp 
when one or more of your tires are significantly 
underinflated. When the low tire pressure warn-
ing lamp lights up, 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 handling and stopping 
ability. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is the 
driver's responsibility to maintain correct tire 
pressure, even if underinflation has not reached 
the level to trigger illumination of the TPMS low 
tire pressure warning lamp.
The TPMS malfunction indicator is combined 
with the low tire pressure warning lamp. When 
the system detects a malfunction, the warning 
lamp will flash for approximately one minute and 
then remain continuously illuminated. This 
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists. 
When the malfunction indicator is illuminated, 
the system may not be able to detect or signal 
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate 
tires or wheels on the vehicle that prevent the 
TPMS from functioning properly. Always check 
the TPMS malfunction warning lamp after 
replacing one or more tires or wheels on your 
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Brake force display
The brake lamps light up in two stages, 
depending on how heavily you apply the brakes.
>
Normal braking
The brake lamps and the center brake lamp 
light up.
>
Heavy braking
The rear fog lamps light up as well.
