BMW BMW M2 COMPETITION, Owner'S Manual

Page: 144 / 278

Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
No reset was performed for the sys‐
tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
Measure
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Actions in the event of a flat tire
1. Identify the damaged tire.
To do this, check the air pressure in all four
tires, for instance using the tire pressure gage
of a flat tire kit.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize the
system.
If identification of flat tire damage is not pos‐
sible, please contact a dealer’s service center
or another qualified service center or repair
shop.
2. Repair the flat tire, e.g., with a flat tire kit or by
changing the wheel.
Use of sealant, for instance from the flat tire kit,
may damage the TPM wheel electronics. In this
case, have the electronics checked and replaced
at the next opportunity.
System limits
Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire infla‐
tion pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Sudden tire pressure loss
The system cannot indicate sudden serious tire
damage caused by external circumstances.
Failure performing a reset
The system does not function properly if a reset
has not been carried out, for instance a flat tire is
reported though tire inflation pressures are cor‐
rect.
Malfunction
The yellow warning light flashes and is
then illuminated continuously. A Check
Control message is displayed. It may not
be possible to identify tire pressure losses.
Examples and recommendations in the following
situations:
▷ A wheel without TPM wheel electronics is
mounted: have it checked by a dealer’s serv‐
ice center or another qualified service center
or repair shop as needed.
▷ Malfunction: have system checked by a deal‐
er’s service center or another qualified serv‐
ice center or repair shop.
▷ The system was unable to complete the re‐
set. Perform a system reset again.
▷ Interference caused by systems or devices
with the same radio frequency: after leaving
the area of the interference, the system auto‐
matically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure
Monitoring System
Each tire, including the spare (if provided) should
be checked monthly when cold and inflated to
the inflation pressure recommended by the vehi‐
cle manufacturer on the vehicle placard or tire in‐
flation pressure label. (If your vehicle has tires of
a different size than the size indicated on the ve‐
