"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.
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
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.
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 example, the spare tire is
removed from a vehicle.
The user will have the possibility to check the
pressure of the spare tire by accessing the TPMS
display menu. For vehicles that have no spare
tires, the title "spare tire" will still appear on the
screens but the pressure will remain with two dash
lines at all time.
Post Trip Operation
When parking the vehicle (park brake applied), the
TPMS display keep the drive mode display active.
The driver can press any keys to get the bottom
lines showing the status information replaced with
the menus.
The pressure readings are still displayed and
updated as new readings are received and the
readings are blinking if not within the optimum
pressure range.
From this point the user can scroll through the
menus to get more detailed information and inflate
or deflate the tires to bring them back to their
optimum target pressures. Scrolling through these
menus is also available prior to departure.
