reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, resetting is continued automati-

1. Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2. Check whether your vehicle is equipped
with standard tires or run-flat tires.
You will recognize run-flat tires by a
circular symbol containing the letters
RSC on the side of the tire, refer to
page 208.<
Standard tires
1. If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.

refer to Changing wheels on page 226.
In contrast to a compact wheel, a spare wheel is
equipped with the necessary TPM electronics
and also monitored after mounting and after
resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Run-flat tires*
1. Cautiously reduce speed to below 50 mph/
80 km/h. Avoid severe braking and steering
maneuvers and do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page 208, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<
2. 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:
