Warning (Continued)
G
USA only: Your vehicle has also been
equipped with a TPMS malfunction indicator
to indicate when the system is not operating
properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately 1 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 illu-
minated, the system may not be able to de-
tect or signal low tire pressure as intended.
Continued
Warning (Continued)
G
TPMS malfunctions may occur for a vari-
ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Al-
ways 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.
