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.
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.
NOTE:
Some external parameters (eg; outdoor tem-
perature) may affect TPMS info on your in-
strument cluster.
What It Means
CAUTION!
The TPMS has been optimized for the origi-
nal equipment tires and wheels. TPMS pres-
sures and warning have been established for
the tire size equipped on your vehicle. Unde-
sirable system operation or sensor damage
may result when using replacement equip-
ment that is not of the same size, type, and/or
style. Aftermarket wheels can cause sensor
damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an
authorized dealer to have your sensor func-
tion checked.
