GMC Acadia/Acadia Denali Owner Manual - 2011
Vehicle Care 10-49
The TPMS can warn about a
low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑51, Tire Rotation on
page 10‑52 and Tires on
page 10‑38.
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.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑63 for
information regarding the inflator
kit materials and instructions.
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 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 malfunction 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.
.
The TPMS sensor matching
process was not done or
not completed successfully
after rotating the tires.
The malfunction light and the
DIC message should go off
after successfully completing
the sensor matching process.
See "TPMS Sensor Matching
Process" later in this section
.
One or more TPMS sensors
are missing or damaged.
The malfunction light and
the DIC message should go
off when the TPMS sensors
are installed and the sensor
matching process is performed
successfully. See your dealer
for service.
