and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. 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 instal-
lation 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.

Changing Tires And Wheels
The following procedure allows the TPMS to
recognize a tire pressure sensor's unique ID
signal code whenever tires or wheels are
changed, such as changing to and from
winter tires.
