Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
''CHECK TIRE PRESSURE''
message.
