The manual says:
"Tire Pressure Monitoring System (TPMS) Indicator

This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position.

If this indicator comes on and stays
on at any other time, or if it does not
come on when you turn the ignition
switch to the ON (II) position, there
is a problem with the TPMS; the
system that monitors tire pressure.
With this indicator on, the low tire
pressure indicator will not come on
when a tire loses pressure. Take the
vehicle to your dealer to have the
system checked."
