Resetting The System - BMW 128i Owner's Manual

Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only required when this is indi-
cated by the TPM.
Green wheels
The inflation pressure corresponds to the
desired state.
"TPM active" appears in the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire.
All wheels yellow
> There is a flat tire or substantial loss of tire
pressure in several tires.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
> TPM is being reset.
> Interference from systems or devices that
use the same radio frequency.
> Malfunction.

Resetting the system

Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.

is completed automatically as you drive. On the
Control Display, the wheels are shown in green

The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
If a flat tire is detected while the system is
resetting, all tires on the Control Display
are displayed in yellow. The message "Low
tire!" is displayed.<
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.

the inflation pressures initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers.
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
