10-56 Vehicle Care
If the warning light comes on,
stop as soon as possible and
inflate the tires to the recommended
pressure shown on the tire loading
information label. See Vehicle Load
Limits on page 9‑18.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires
are inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed.
For additional information and
details about the DIC operation
and displays see Driver Information
Center (DIC) on page 5‑23.
The low tire pressure warning
light may come on in cool weather
when the vehicle is first started, and
then turn off as the vehicle is driven.
This could be an early indicator that
the air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9‑18, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑53.
The TPMS can warn about
a low tire pressure condition
but it does not replace normal
tire maintenance. See Tire
Inspection on page 10‑59,
Tire Rotation on page 10‑59
and Tires on page 10‑46.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using
an incorrect tire sealant is
not covered by the vehicle
warranty. Always use only
the GM-approved tire sealant
available through your dealer
or included in the vehicle.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When
the system detects a malfunction,
the low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message also displays. The low
tire pressure warning light and DIC
warning message come on at each
ignition cycle until the problem is
corrected. Some of the conditions
that can cause these to come
on are:
.
One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The malfunction
light and DIC message should
go off after the road tire is
replaced and the sensor
matching process is performed
successfully. See "TPMS Sensor
Matching Process" later in this
section.
