DRIVING AND OPERATING
After selecting Start from the Learn
Sensors screen, use the Tool Method
or the Manual Method (described
below) to learn each tire sensor,
during which the current tire number
will be highlighted.
Each sensor has a minimum of
two minutes to learn, shown by a
timer. After a sensor is learned, a
checkmark appears next to the tire,
the vehicle horn will sound, the
vehicle
’
s brake lamps will flash, and
all working trailer lamps will flash.
It then moves to the next sensor.
To cancel the process touch Stop.
The recommended tire pressure must
be entered for the trailer tires. This
allows the vehicle to alert when the
tire pressure is high or low.
TTPMS must learn the location of the
installed tire sensors to show correct
air pressure and temperature for each
tire. To set up, use one of the
following options or see a tire or
trailer dealer for service. The learning
process must be repeated when the
trailer tires are rotated or replaced.
See
“
Editing a Trailer Profile
”
later in
this section for tire pressure sensor
relearn information.
Tool Method: A TTPMS activation tool
can be purchased separately to learn
the sensor locations.
Manual Method: Without the tool, the
air pressure can be increased or
decreased in each tire for 10 seconds.
Do not exceed the maximum inflation
pressure found on the tire sidewalls.
Make sure to re-adjust tire pressure to
the recommended level when the
process is complete.
