Warning of low tire inflation pressure
Malfunction
The warning lamp lights up in yellow. A
signal also sounds. There is a flat tire or
a significant loss of tire pressure in one
or more tires.
The yellow warning lamp flashes and
then lights up continuously. A flat tire
cannot be detected.
This warning is displayed under the following
circumstances:
1.
Cautiously reduce speed to 50 mph/
80
steering maneuvers. Do not exceed a maxi-
mum speed of 50 mph/80 km/h.

In the event of complete tire pressure loss,
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
0
psi/0 kilopascal, you can estimate how far
you can continue driving on the basis of the
following guidelines:
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.
Under-inflation 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 under-
inflation has not reached the level to trigger illu-
mination of the TPMS low tire pressure telltale.

Drive cautiously. Do not exceed a speed
of 50 mph/80 km/h. Driving characteris-
tics change if there is a loss of tire pressure.
This includes reduced tracking stability in brak-
ing, extended braking distance and altered nat-
ural steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over to the side of the road at a
suitable location at the earliest opportunity.
Otherwise, parts of the tire could come loose
and cause an accident. Do not continue driving.
Contact a BMW center.<
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
