TIRE PRESSURE MONITORING SYSTEM
(TPMS) (OPTIONAL)
The vehicle may be equipped with the optional
Tire Pressure Monitoring System (TPMS).
Description
System includes the following elements:

Special tire valves;

RF sensor inside each tire, fixed to the
valve;

3 antennas to receive the sensors RF signal
(one in the front spare tire compartment, one
above the L.H. side rear wheels and one
above the R.H. side rear wheels);

A TPMS receiver connected to the antennas
and
located in the front electrical
compartment, on top of the CECM;

A TPMS display built in the L.H. dashboard
panel;

A “FLAT TIRE” telltale panel indicator.
The section of the special tire valves located
inside the tire is dome-shaped to allow fixing the
sensor.
Sensors provide continuous tire pressure and
temperature reading.
The normal sensor battery lifespan is 5 years.
The remaining lifespan is displayed as a
percentage in the TPMS display.
NOTE
It is recommended to check the remaining
battery lifespan when changing the tires in
order to replace the sensors at the same time
if they are due for replacement before the next
change.
The sensor
’s fixation screw to the valve can only
be used once because the threads are powder-
coated to lock the sensor in place and prevent
unfastening.
The telltale panel indicator illuminates for 3
seconds when the ignition switch is turned ON to
check
the display operation and the
communication between the display and the
vehicle multiplex system. This confirms the
communication between the TPMS display and
CECM.
