Your vehicle has also been equipped
with a TPMS malfunction indicator to
signal when the system is not
operating properly.
The TPMS malfunction indicator works
in combination with the low tire
pressure warning light.
When the system detects a
2
malfunction, the warning light will
flash for approximately one minute
and then remain permanently
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 warning light 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.

System calibration

After replacing or inflating one or
more tires, the system must be
calibrated once again.
To calibrate the system, keep button A,
located on the inside roof, pressed
down for a time ranging between 4
and 10 seconds. The system takes a
maximum of 20 minutes to complete
the calibration procedure with the
vehicle in motion.
A green symbol will appear on the
display together with the message
"Calibration activated".
If the user recalls the information page
showing the pressure levels of each
tire, dashes "–.–" will be viewed in the
place of the values.
Viewing messages on the display
By pressing the specific "Mode"
button B, (see page 77), the user can
access the information page showing
the pressure values for each tire.
When indication by event occurs, the
malfunction is viewed in the place of
the information on tire pressure levels.
The malfunction is displayed for a time
equal to its entire display cycle. When
the display cycle ends, the tire pressure
screen page becomes available again
and the multi-function symbol
indicating the malfunction is displayed
in the specific area until the
malfunction is rectified.
