tire or substantial loss of tire pressure.
1.
Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page
dard equipment by design, do not continue
driving. Any attempt to drive on after a
puncture can result in a severe accident.

At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.

3.
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 guidelines:
>
With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>
With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 90 miles/150 km
>
With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph or 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 to the side of the road at the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact your BMW cen-
ter.
