Tire Pressure Monitoring System
pressure sensors are mounted into
each tire on your trailer. The
sensors send a message to your
vehicle indicating the current
trailer tire pressure and
temperature.
If the trailer tire pressure
monitoring system detects that a
tire is low, a warning message
appears in the information display.
The trailer tire information screen
in the information display
highlights the tire with a low
pressure.
If the trailer tire pressure
monitoring system detects that a
tire temperature is over temp, a
warning message appears in the
Information display. The trailer tire
information screen in the
information display highlights the
tire with a high temperature.
The main function of the trailer tire
pressure monitoring system is to
warn you when your trailer tires
need air or if the tires are
experiencing high temperatures.
It can also warn you in the event
the system is no longer capable
of functioning as intended. See
