This shows that front left tire is
losing pressure.
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.
2011 RDX
When any of the tires have low
pressure, the tire pressure monitor
shows a ''TIRE PRESS. ERROR
SYSTEM FUNC NORMAL''
message.
When you continue driving after
installing the spare tire, you will also
see this message on the multi-
information display.
