Tires
Inflation - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice:
Do not let anyone tell you that
under‐inflation or over‐inflation is all right.
It is not. If your tires do not have enough air
(under‐inflation), you can get the following:
.Too much flexing
.Too much heat
.Tire overloading
.Premature or irregular wear
.Poor handling
.Reduced fuel economy
If your tires have too much air (over‐inflation),
you can get the following:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from road hazards
A vehicle specific Tire and Loading Information label is
attached to your vehicle. This label shows your
vehicle's original equipment tires and the correct
inflation pressures for your tires when they are cold.
The recommended cold tire inflation pressure, shown
on the label, is the minimum amount of air pressure
needed to support your vehicle's maximum load
carrying capacity.
For additional information regarding how much weight
your vehicle can carry, and an example of the Tire and
Loading Information label, see “Loading Your Vehicle”in
the Index of the owner manual. How you load your
vehicle affects vehicle handling and ride comfort. Never
load your vehicle with more weight than it was designed
to carry.

When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Check the tire's inflation pressure when the tires are
cold. Cold means your vehicle has been sitting for at
least three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the tire and loading
information label, no further adjustment is necessary.
If the pressure is low, add air until you reach the
recommended amount.
If you overfill the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle's tires
and transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
symbol located on the
instrument panel cluster.
At the same time a message to check the pressure
in a specific tire appears on the Driver Information
Center (DIC) display. 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 by the driver. For
6-29
Page 86 of 120
additional information and details about the DIC
operation and displays seeDIC Warnings and
Messages
on page 4‑12. Also, see “DIC Operation and
Displays” in the Index of the owner manual for more
information.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. See “Loading
Your Vehicle” for an example of the Tire and Loading
Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 6‑28. Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See
“Tire Inspection and Rotation” and
“Tires” in the Index of the owner manual for more
information.
Notice: Using non‐approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using an
incorrect tire sealant is not covered by the vehicle
warranty. Always use the GM approved tire sealant
available through your dealer/retailer.
Your vehicle, when new, included a factory‐installed
Tire Sealant and Compressor Kit. This kit uses a
GM approved liquid tire sealant. See Tire Sealant and
Compressor Kit (Without Selector Switch)
on
page 6‑35or Tire Sealant and Compressor Kit
(With Selector Switch) on page 6‑45.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you rotate your vehicle's tires or replace one
or more of the TPMS sensors, the identification codes
will need to be matched to the new tire/wheel position.
The sensors are matched to the tire/wheel positions in
the following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the
tire's air pressure. If increasing the tire's air pressure,
do not exceed the maximum inflation pressure indicated
on the tire's sidewall.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gage, or a key.
You have two minutes to match the first tire/wheel
position, and five minutes overall to match all four
tire/wheel positions. If it takes longer than two minutes,
to match the first tire and wheel, or more than
five minutes to match all four tire and wheel positions
the matching process stops and you need to start over.The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Press
QandKon the Remote Keyless Entry
(RKE) transmitter at the same time for
approximately five seconds. The horn sounds
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. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, 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.
6-32
Page 89 of 120
8. Proceed to the driver side rear tire, and repeat theprocedure 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 ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See “When It Is
Time for New Tires” and“Wheel Replacement” in the
Index of the owner manual for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance” in the Index of the owner manual.
When rotating your tires, always use the correct rotation
pattern shown here.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire and
Loading Information label. See “Loading Your Vehicle”
in the Index of the owner manual for an example of the
label and its location on your vehicle.
The Tire Pressure Monitor System (TPMS) sensors will
need to be reset after a tire rotation. See “TPMS Sensor
Identification Codes” under“Tire Pressure Monitor
Operation”.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under“Capacities and
Specifications” in the Index of the owner manual.

If the vehicle has the tire sealant and compressor kit
shown above, follow the operating instructions under
“Tire Sealant and Compressor Kit (With Selector
Switch).”
{WARNING:
Idling a vehicle 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 an enclosed area
that has no fresh air ventilation. For more
information, see”Engine Exhaust” in the owner
manual.
{WARNING:
Over-inflating 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.
6-36
Page 93 of 120
{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 ¼ inch (6 mm) in the
tread area of the tire. It can also be used to inflate an
under inflated 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” in the owner manual. Read and follow all of the tire sealant and compressor
kit instructions.
The kit includes:
A. Air Compressor
B. Tire Sealant Canister
C. Power Plug
D. On/Off Button E. Pressure Gage
F. Air Only Hose (Black)
G. Sealant/Air Hose (Clear)
6-37

Always do a safety check first. SeeIf a Tire Goes Flaton page 6‑34.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑55.
Make sure the on/off button (D) is in the off (O)
position.
2. Unwrap the sealant/air hose (F) and the power plug (C).
3. Place the kit on the ground. Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it counterclockwise.
5. Attach the sealant/air hose (F) onto the tire valve stem. Turn it clockwise until it is tight. 6. Plug the power plug (C) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets. See “Accessory Power
Outlet(s) in the owner manual.”
If the vehicle has an accessory power outlet,
do not use the cigarette lighter.
If the vehicle only has a cigarette lighter, use the
cigarette lighter.
Do not pinch the power plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running while using the air compressor.
8. Press the on/off (D) button to turn the tire sealant and compressor kit on.
The compressor will inject sealant and air into
the tire.
The pressure gage (E) will initially show a high
pressure while the compressor pushes the sealant
into the tire. Once the sealant is completely
dispersed into the tire, the pressure will quickly
drop and start to rise again as the tire inflates with
air only.
6-39
Page 96 of 120
9. Inflate the tire to the recommended inflationpressure using the pressure gage (E).
The recommended inflation pressure can be
found on the Tire and Loading Information label.
See Inflation - Tire Pressure on page 6‑28.
The pressure gage (E) may read higher than the
actual tire pressure while the compressor is on.
Turn the compressor off to get an accurate
pressure reading. The compressor may be turned
on/off until the correct pressure is reached.
Notice: If the recommended pressure cannot be
reached after approximately 25 minutes, the vehicle
should not be driven farther. The tire is too severely
damaged and the tire sealant and compressor kit
cannot inflate the tire. Remove the power plug from
the accessory power outlet and unscrew the
inflating hose from the tire valve. See “Roadside
Assistance Program” in the owner manual. 10. Press the on/off button (D) to turn the tire sealant
and compressor kit off.
The tire is not sealed and will continue to
leak air until the vehicle is driven and the
sealant is distributed in the tire, therefore,
Steps 11 through 17 must be done immediately
after Step 10.
Be careful while handling the tire sealant and
compressor kit as it could be warm after usage.
11. Unplug the power plug (C) from the accessory power outlet in the vehicle.
12. Turn the sealant/air hose (F) counterclockwise to remove it from the tire valve stem.
13. Replace the tire valve stem cap.
14. Replace the sealant/air hose (F), and the power plug (C) back in their original location.
