For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System.
This indicates that one or more of
the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC), can
accompany the light. See
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire
loading information label. See
information.
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
