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 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.
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.
