Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of 
50 mph/80 km/h.
Stop driving if the vehicle is no longer 
equipped with run-flat tires, as it was 
when it came from the factory, refer to 
page
. Continued driving after a flat tire 
can result in serious accidents.

In the event of complete tire pressure loss, 
0 psi/0 kPa, you can estimate the possible 
distance for continued driving on the basis 
of the following guide values:
>
With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>
With a medium load:
2 persons, cargo bay full, or 
4 persons without luggage:
approx. 95 miles/150 km
>
With a full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a 
speed of 50 mph/80 km/h. In the event of 
pressure loss, vehicle handling changes. This 
includes reduced tracking stability in braking, 
extended braking distance and altered natural 
steering characteristics.
If unusual vibrations or loud noises occur while 
the vehicle is being driven, this can indicate final 
failure of the damaged tire. Reduce speed and 
stop at a suitable location as soon as possible, 
otherwise pieces of the tire could become 
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW 
center.

Malfunction
The yellow warning lamp flashes and 
then lights up continuously. The tires 
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can 
be detected.
A message like this is displayed in the following 
situations:
>
In case of a malfunction;
have the system checked.
>
If a wheel is mounted without TPM elec-
tronics.
>
If TPM is temporarily interfered with by 
other systems or devices which use the 
same radio frequency.
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 underinflated. 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-
dling and stopping ability. Please note that the 
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to 
maintain correct tire pressure, even if underin-
flation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined 
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash 
for approximately one minute and then remain 
continuously illuminated. This sequence will 
continue upon subsequent vehicle startups as 
long as the malfunction exists. When the mal-
function indicator lights up, the system may not 
be able to detect or signal low tire pressure as 
intended. TPMS malfunctions may occur for a 
variety of reasons, including the installation of
