In the event of complete pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:

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, cargo bay full:
approx. 30 miles/50 km

Drive cautiously 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 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 as soon as possible at a
suitable location. Otherwise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.

Malfunction

The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. No punctures can be

detected.
This type of message is shown in the following
situations:

If there is a malfunction
Have the system checked.

If a wheel without TPM electronics has
been mounted

If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.

Message for unsuccessful system

reset

The warning lamp lights up yel-
low.The system is not reset after a
tire has been changed, for example.
Check the tire inflation pressure and

reset the system, refer to page

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 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.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
