each ignition cycle until the tires are
inflated to the correct inflation
pressure. If the vehicle has DIC
buttons, tire pressure levels can be
viewed. For additional information
and details about the DIC operation
and displays, seeDriver Information
Center (DIC) 099.
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 0158, for an example of the
Tire and Loading Information label
and its location. Also see Tire
Pressure 0263.
The TPMS can warn about a low
tire pressure condition but it does not replace normal tire
maintenance. See
Tire Inspection
0 268, Tire Rotation 0268 and
Tires 0255.
Caution
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
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 the 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.

twice to signal the receiver is in
relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
6. Proceed to the passenger side front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure
in Step 5. The horn sounds two
times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the vehicle off.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, 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). See
Maintenance Schedule 0305.
Tires are rotated to achieve a
uniform wear for all tires. The
first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the

13882570) - 2020 - CRC - 11/1/19
Vehicle Care 269
unusual wear continues after the
rotation, check the wheel
alignment. SeeWhen It Is Time
for New Tires 0270 and
Wheel Replacement 0275.
If the full-size spare tire is part of
the tire rotation, make sure the
tire rotated into the spare
position is stored securely.
Push, pull, and then try to rotate
or turn the tire. If it moves, use
the wheel wrench/hoist shaft to
tighten the cable. See Tire
Changing 0278.Use this rotation pattern when
rotating the tires if the vehicle
has single rear wheels.
Use this rotation pattern when
rotating the tires if the vehicle
has dual rear wheels.
When installing dual wheels,
check that the vent holes in the
inner and outer wheels on each
side are lined up.
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
0263 and
Vehicle Load Limits 0158.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0265.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications 0318.
{Warning
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make wheel
nuts become loose after time.
The wheel could come off and
cause a crash. When
changing a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, a
cloth or a paper towel can be

used; however, use a scraper
or wire brush later to remove
all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Dual Tire Rotation
When the vehicle is new,
or whenever a wheel, wheel bolt,
or wheel nut is replaced or serviced,
check the wheel nut torque after
160, 1 600, and 10 000 km (100,
1,000, and 6,000 mi) of driving. For
proper torque and wheel nut
tightening information, see “Removing the Flat Tire and
Installing the Spare Tire”
underTire
Changing 0278 and“Wheel Nut
Torque” underCapacities and
Specifications 0318.
The outer tire on a dual wheel setup
generally wears faster than the
inner tire. Tires last longer and wear
more evenly if they are rotated. See
Tire Inspection 0268 and
Tire Rotation 0268. Also see
Maintenance Schedule 0305.
See Tires 0255 and
Tire Pressure 0263 for more
information on proper tire inflation.
When It Is Time for New
Tires
Factors, such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. Some
commercial truck tires may not have
treadwear indicators. See Tire
Inspection 0268 and
Tire Rotation 0268 for additional
information.
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging

9. Return the jacking equipment to the proper location. Secure
the items and replace the jack
cover.
Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure0263
and
Vehicle Load Limits 0158. For
instructions on how to remove,
install, or store a spare tire, see Tire
Changing 0278. After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare is correctly
inflated. The spare tire is made to
perform well at speeds up to
112 km/h (70 mph) at the
recommended inflation pressure, so
you can finish your trip.
Have the damaged or flat road tire
repaired or replaced back onto the
vehicle, as soon as possible, so the
spare tire will be available in case it
is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep the spare tire and its wheel
together.
If this vehicle has a spare tire that
does not match the original road
tires and wheels in size and type,
do not include the spare in the tire
rotation.
If equipped with a temporary use
full-size spare tire, it is indicated on
the tire sidewall. See
Tire Sidewall
Labeling 0257. The spare tire
should not be driven on over
112 km/h (70 mph), or 88 km/h
(55 mph) when pulling a trailer, at the proper inflation pressure. Repair
and replace the road tire as soon as
it is convenient, and stow the spare
tire for future use.
