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. SeeVehicle Load
Limits on page 9‑14, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑54.
The TPMS can warn about
a low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑61, Tire Rotation on
page 10‑61, and Tires on
page 10‑48. 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 10‑71 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 pressure warning light
flashes for about one minute and
then stays on for the remainder
of the vehicle on/off cycle. A DIC
warning message also displays.
The malfunction light and DIC
warning message come on at
each vehicle on/off 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, if the vehicle has one.
The spare tire does not
have a TPMS sensor.

Tire Inspection
GM recommends that the
tires, including the spare, be
inspected for signs of wear or
damage at least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord
or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). The first
rotation is the most important.
SeeScheduled Maintenance on
page 11‑2.
Tires are rotated to achieve a
more uniform wear for all tires.
Any time unusual wear is
noticed, rotate the tires as
soon as possible, and
check the wheel alignment.
See When It Is Time for New
Tires on page 10‑62 andWheel
Replacement on page 10‑67.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label
after the tires have been
rotated. See Tire Pressure on
page 10‑54 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑57.

{WARNING
Running the engine in Extended
Range Mode in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in Extended Range Mode
in an enclosed area that has no
fresh air ventilation. For more
information, seeEngine Exhaust
on page 9‑30.
{WARNING
Overinflating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire
sealant and compressor kit
instructions and inflate the tire
to its recommended pressure.
Do not exceed the recommended
pressure.
{WARNING
Storing the tire sealant
and compressor kit or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store the tire
sealant and compressor kit in
its original location. If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.
The tire sealant and compressor
can be used to temporarily seal
punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be
used to inflate an underinflated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire is
too severely damaged for the tire
sealant and compressor kit to be
effective. See
Roadside Assistance
Program on page 13‑6.
Read and follow all of the tire
sealant and compressor kit
instructions.
