Chevrolet 2007 Colorado Owner's Manual page 387

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
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.
A Tire and Loading Information label, attached
to your vehicle, shows the size of your vehicle's
original equipment tires and the correct inflation
pressure for your vehicle's tires when they
are cold. See Loading Your Vehicle on page 293,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 384
for additional information.
Your vehicle's TPMS can warn you about a low
tire pressure condition but it does not replace
normal tire maintenance. See Tire Inspection
and Rotation on page 390, When It Is Time for
New Tires on page 391, and Tires on page 377.
Notice: Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The
liquid sealant can damage the tire pressure
monitor sensors.
