pressure telltale. When the system detects a mal-
function, the telltale will flash for approximately
one minute and then remain continuously illumi-
nated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, 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 alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Messages in the instrument panel
If tire pressure is too low, the low tire pressure
warning symbol is shown in the instrument panel

To keep in mind
• Always save the new inflation pressure in the
system after changing a tire or adjusting the
inflation pressure.
•
If you switch to a tire of another size than the
factory-mounted tires, the system must be
reset by storing a new inflation pressure for
these tires to avoid false warnings.

•
the tire pressure monitoring system will not
work correctly due to the differences
between the wheels.
• The system does not replace the need for
regular tire inspection and maintenance.
• It is not possible to deactivate the tire pres-
sure monitoring system.
WARNING
• Incorrect inflation pressure could lead to
tire failure, which could cause the driver
to lose control of the vehicle.
• The system cannot predict sudden tire
damage.
