Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may
not have been reset. The system must then
be reset.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics change, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steering response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change.<

Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result 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 large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the following situations:
> A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
> Malfunction
Have the system checked.
> Tire Pressure Monitor was unable to com-
plete the resetting process. Reset the sys-
tem again.
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the following situations:
> Interference from systems or devices that
use the same radio frequency:
The system automatically becomes active
again when the vehicle moves out of the
interference zone.

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-
