A rectangle around each pressure / temperature
reading of the tires that have an issue is blinking
to draw the attention to the defective tires.
In the case of multiple errors at the same time,
the highest priority error is displayed at the
bottom. “Flat Tire” has the highest priority
followed by “High Temperature”, “Not all tires
monitored” and “Tire pressure not Optimal”.
To get the driver’s attention to the alarms, the
bottom section of the screen where the alarm
message appears will blink to reverse contrast
at the following rate: 0.7 sec normal contrast, 0.3
sec reverse contrast. Pressing any key will
acknowledge the alarms that are considered as
non critical and stop the blinking of these alarms
message for the remaining of the trip. The non
critical alarms are: “Pressure not optimal” and
“Not all tires monitored”. The “flat tires” and “high
temperature” alarms are critical and will keep
blinking even when a key is pressed. If a
different alarm occurs, blinking will start again.
The blinking rectangle around the pressure
/temperature readings is not impacted by the
acknowledgement and keeps blinking until the
error condition disappears.
The spare tire does not contribute to alarms and
so never blinks.
On the road, the TPMS display shows one of the
5 previous screens.
In the event of a temperature alarm, the display
switches automatically to temperature readings.
The driver can also press any of the menu keys
to momentary switch the display to temperature
readings. In this case, the temperature reading
appears for 15 seconds and the display returns
to pressure.
The switching to temperature by pressing a key
does not take place if there is an
acknowledgeable alarm active, since in this
case pressing the key does acknowledge the
alarm.
The switching to temperature does not take
place either if there is an alarm of Temperature
or Flat Tire.
The switching to temperature works when the
bottom message indicates either: Tire Pressure
OK, Pressure Not Optimal non flashing or not all
tires monitored non flashing. When the switch is
done to temperature readings, the bottom
portion of the screen is not affected and still
shows the status message.
NOTE
High temperature is not likely to occur during
the pre-trip.
The pressure and temperature readings are
continuously updated with the displayed
readings of the wheel having issues blinking.
The bottom line message is automatically
updated to the highest priority alarm prevailing.
There is a hysteresis on the alarm levels to
assure that the error conditions do not flicker ON
and OFF.
On the occurrence of an alarm, a beep will
sound. The alarm beep could be turned OFF in
the alarm settings menu.
Spare tire:
The spare tire is monitored but it is not taken
into account when setting the bottom alarm
messages. This is to prevent unnecessary
alarms that would otherwise occur, if for
