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.
.Replacement tires or wheels
do not match the original
equipment tires or wheels.
Tires and wheels other than
those recommended could
prevent the TPMS from
functioning properly. See
Buying New Tires0395.
.Operating electronic devices
or being near facilities using
radio wave frequencies
similar to the TPMS could
cause the TPMS sensors to
malfunction. If the TPMS is not functioning
properly it cannot detect or
signal a low tire pressure
condition. See your dealer for
service if the TPMS
malfunction light and DIC
message come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual
and audible alerts outside the
vehicle to help when inflating
an underinflated tire to the
recommended cold tire
pressure.
When the low tire pressure
warning light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn
signal lamp will flash. When the recommended
pressure is reached, the
horn sounds once and the
turn signal lamp will stop
flashing and briefly turn
solid.
Repeat these steps for all
underinflated tires that have
illuminated the low tire
pressure warning light.
{Warning
Overinflating a tire could
cause the tire to rupture
and you or others could be
injured. Do not exceed the
maximum pressure listed on
the tire sidewall. See Tire
Sidewall Labeling 0378 and
Vehicle Load Limits 0247.
If the tire is overinflated by
more than 35 kPa (5 psi), the
horn will sound multiple times
and the turn signal lamp will
continue to flash for several
seconds after filling stops. To
release and correct the
pressure, while the turn signal

lamp is still flashing, briefly
press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does
not flash within 15 seconds
after starting to inflate the
tire, the tire fill alert has not
been activated or is not
working.
If the hazard warning flashers
are on, the tire fill alert visual
feedback will not work
properly.
The TPMS will not activate the
tire fill alert properly under the
following conditions:
.There is interference from
an external device or
transmitter.
.The air pressure from the
inflation device is not
sufficient to inflate the tire.
.There is a malfunction in
the TPMS.
.There is a malfunction in the
horn or turn signal lamps.
.The identification code of
the TPMS sensor is not
registered to the system.
.The battery of the TPMS
sensor is low.
If the tire fill alert does not
operate due to TPMS
interference, move the vehicle
about 1 m (3 ft) back or
forward and try again. If the
tire fill alert feature is not
working, use a tire pressure
gauge.
TPMS Sensor Matching
Process
Each TPMS sensor has a
unique identification code. The
identification code needs to be
matched to a new tire/wheel
position after rotating the
vehicle’s tires or replacing one
or more of the TPMS sensors.
The TPMS sensor matching
process should also be
performed after replacing a
spare tire with a road tire
containing the TPMS sensor.
The malfunction light and the DIC message should go off at
the next ignition cycle. The
sensors are matched to the
tire/wheel positions, using a
TPMS relearn tool, in the
following order: driver side
front tire, passenger side front
tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to
purchase a relearn tool.
A TPMS relearn tool can also
be purchased. See Tire
Pressure Monitor Sensor
Activation Tool at www.
gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
There are two minutes to
match the first tire/wheel
position, and five minutes
overall to match all four tire/
wheel positions. If it takes
longer, the matching process
stops and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.

16406251) - 2023 - CRC - 3/28/22
Vehicle Care 399
law. Warning: The
temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation,
or excessive loading, either
separately or in
combination, can cause
heat buildup and possible
tire failure.
Wheel Alignment and
Tire Balance
The tires and wheels were
aligned and balanced at the
factory to provide the longest
tire life and best overall
performance. Adjustments to
wheel alignment and tire
balancing are not necessary
on a regular basis. Consider an
alignment check if there is
unusual tire wear or the
vehicle is significantly pulling
to one side or the other. Some
slight pull to the left or right,
depending on the crown of theroad and/or other road
surface variations such as
troughs or ruts, is normal.
If the vehicle is vibrating when
driving on a smooth road, the
tires and wheels may need to
be rebalanced. See your
dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is
bent, cracked, or badly rusted
or corroded. If wheel nuts
keep coming loose, the wheel,
wheel bolts, and wheel nuts
should be replaced. If the
wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel that is needed.
Each new wheel should have
the same load-carrying
capacity, diameter, width,
offset, and be mounted the
same way as the one it
replaces.
Replace wheels, wheel bolts,
wheel nuts, or Tire Pressure
Monitor System (TPMS)
sensors with new GM original
equipment parts.
{Warning
Using the wrong
replacement wheels, wheel
bolts, or wheel nuts can be
dangerous. It could affect
the braking and handling of
the vehicle. Tires can lose air
and cause loss of control,
resulting in a crash. Always
use the correct wheel, wheel
bolts, and wheel nuts for
replacement.
{Warning
Replacing a wheel with a
used one is dangerous. How
it has been used or how far
it has been driven may be
unknown. It could fail
suddenly and cause a crash.

they are worn or damaged.
Damage can be caused by
extreme dusty conditions,
sand, salt, heat, sun, snow,
and ice.
Weatherstrips
Apply weatherstrip lubricant
on weatherstrips to make
them last longer, seal better,
and not stick or squeak.
Lubricate weatherstrips at
least once a year. Hot, dry
climates may require more
frequent application. Black
marks from rubber material on
painted surfaces can be
removed by rubbing with a
clean cloth. See
Recommended Fluids and
Lubricants
0433.
Tires
