o
Driving on a significantly under-inflated tire can cause the tire to overheat and
lead to tire failure. Under-inflation also reduces fuel efficiency and tread life
which can potentially affect the vehicle’s handling and stopping ability.
High Pressure (Optional Alarm) – Tire pressure is 25% or more above the
programmed baseline air pressure.
o
If the High Pressure alarm is activated and occurs, the Green Means Good™
indicator light will go out, and audible alarm will sound at a rate of one beep
per second, and HIGH PRESSURE will be displayed on the monitor screen.
o
This alarm can be generated by a dragging brake, bad wheel bearing,
extreme temperature conditions, or other mechanical failures.
Lost Signal – Occurs when the monitor does not receive the RF signal from a
sensor.
o
If the monitor is unable to receive a signal from a
sensor for more than 60 minutes, an alarm will
be displayed for that sensor (See Figure 4-3).
Hot
–
Sensor temperature is above 175
℉
(80
℃
). This could indicate suspension
or wheel component malfunction.
o
When a Hot alarm occurs, HOT will be displayed on the monitor (See Figure
4-4). NOTE, an Under Pressure or Extreme Under Pressure alarm will over-
ride a “HOT” alarm because of the potential danger of a low pressure tire.
When the HOT warning appears, STOP and check your tire(s) as soon as safely
possible, and check for the possible cause.
NOTICE: A “LOW PRESSURE” warning will over-ride a “HOT” warning because of
the potential danger of a low pressure tire.
