Message for low tire inflation pressure The warning lamps come on in yellow and red. In addition, a signal sounds. There is a flat tire or substantial loss of tire pressure. 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid sudden braking and steering maneuvers. Do not exceed a speed of 50 mph/80 km/h. If the car is not equipped with RunFlat Tires, refer to page 112, the standard equipment by design, do not continue driving. Otherwise a severe accident could result after a tire puncture if you continue driving.< 2. 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 continuously; the larger warning lamp comes on in yellow. No punctures can be detected.

Message for unsuccessful system reset The warning lamp lights up yellow.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 68. Declaration according to NHTSA/ FMVSS 138 Tire Pressure Monitoring Systems Each tire should be checked monthly when cold and inflated to the inflation pressure recommended 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 inflation 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 system, TPMS, that illuminates a low tire pressure telltale when one or more of your tires are significantly 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 han69 Online Edition for Part no. 01 41 2 600 853 - © 08/08 BMW AG Reference Mobility Driving tips Controls At a glance

Message for low tire inflation pressure
The warning lamps come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or substantial loss
of tire pressure.
1.
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.
If the car is not equipped with Run-
Flat Tires, refer to page
112
, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture if you continue
driving.
<
2.
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
68
.
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-
