indicate when the system is not
operating properly.
IMPORTANT The TPMS malfunction
indicator is combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing one
or more tires or wheels on your vehicle
to ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function properly.
IMPORTANT To avoid false readings,
the system samples for a little while
before indicating a problem. As a result
it will not instantaneously register a
rapid tire deflation or blow out.
Because this system detects slight
changes in tire conditions, the timing of
the warning may be faster or slower in
the following cases.
the size, manufacturer, or the type of
tires is different from the specification;
the size, manufacturer, or the type of
a tire is different from the others, or the
level of tire wear is excessively different
between them;
a run-flat tire (where provided),
studless tire, snow tire, or tire chains
are used;
an emergency tire is used (tire
pressure monitoring system warning
light may flash and then continue
illuminating);
a tire is repaired using the emergency
flat tire repair kit;
the tire pressure is excessively higher
than the specified pressure, or the tire
pressure is suddenly lowered for some
reason such as a tire burst during
driving;
the vehicle speed is lower than about
15 km/h (9 mph) (including when the
vehicle is stopped), or the drive period
is shorter than 5 minutes;
the vehicle is driven on an extremely
rough road or a slippery, icy road;
hard steering and rapid
acceleration/deceleration are repeated
such as during aggressive driving on a
winding road;
load on the vehicle is applied to a tire
such as by loading heavy luggage to
one side of the vehicle;
system initialization has not been
implemented with the specified tire
pressure.
System error activation
When the TPMS warning light flashes,
there may be a system malfunction.
Contact a Fiat Dealership.
A system error activation may occur in
the following cases:
when there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors;
when a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire pressure sensor to
the receiver unit;
when using the following devices in
the vehicle that may cause radio
interference with the receiver unit;
a digital device such as a personal
computer;
a current converter device such as a
DC-AC converter;
when excess snow or ice adheres to
the vehicle, especially around the
wheels;
when the tire pressure sensor
batteries are exhausted;
