Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check 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.
Your vehicle has a Tire Pressure Monitor System
(TPMS) that sends tire pressure information to
the Driver Information Center (DIC). Using the DIC
control buttons, the driver is able to check tire
pressure levels in all four road tires. See
Tire Pressure Monitor System on page 414and
DIC Controls and Displays on page 240for
additional information.Professional Vehicle
The proper ination of the tires on your
professional vehicle depends on the type of
tires on it.
If your vehicle has P235/60R17 size tires, the
cold ination pressure is 41 psi (284 kPa).
If your vehicle has LT235/60R17E size tires,
the cold ination pressure depends on the
vehicle mass and should be determined by the
vehicle coach-builder. A tire and loading
information label provided by the nal stage
manufacturer should be attached to the B-pillar
on the driver’s side of the vehicle. If the nal
stage manufacturer’s label is not present,
the coach-builder should be consulted. Do not
use the tire pressures indicated on the
General Motors label. These tire pressures
are for the incomplete vehicle and are not the
correct tire pressures for the completed
professional vehicle.
Operation at ination pressures below this
recommendation may cause your tires to become
overloaded.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. Sensors are mounted on each tire and
wheel assembly, except the spare tire. The TPMS
sensors monitor the air pressure in your vehicle’s
tires and transmit 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. A Driver Information Center (DIC) message
to check the pressure in a specic tire will also
appear on the DIC display. The low tire pressure
warning symbol on the instrument panel cluster
and the CHECK TIRE PRESSURE message
on the DIC display will appear at each ignition
cycle until the tires are inated to the correct
ination pressure. For additional information and
details about the DIC operation and displays
seeDIC Controls and Displays on page 240and
DIC Warnings and Messages on page 246.
You may notice, during cooler weather conditions,
that the low tire pressure warning symbol and
the CHECK TIRE PRESSURE message willdisplay when the vehicle is rst started and then
turn off as you start to drive the vehicle. This could
be an early indicator that the tire pressures are
getting low and need to be checked and inated to
the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)
As an added safety
feature, your vehicle has
been equipped with a
tire pressure monitoring
system (TPMS) that
illuminates a low tire
pressure telltale when
one or more of your tires
is signicantly
under-inated.

Resetting the TPMS Sensor
Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors, rotate the vehicle’s tires, or
install a full-size spare that has a TPMS sensor,
the sensor’s identication codes will need to
be matched to the new tire/wheel position. Each
tire/wheel position is matched to the TPMS sensor
using a TPMS diagnostic tool. See your GM
dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
air pressure, do not exceed the maximum tire
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all
four tire and wheel positions the matching process
stops and you will need to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Press the Driver Information Center (DIC)
vehicle information button until the PRESS
VTO RELEARN TIRE POSITIONS displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate that the TPMS is ready,
and then the message TIRE LEARNING
ACTIVE will display. The sensor matching
process can begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds. The
horn chirp, which may take up to 30 seconds,
conrms that the sensor identication code has
been matched to this tire position. To decrease
the tire’s air-pressure use the pointed end of
the valve cap, a pencil-style air pressure gage
or a key.
416

7. Proceed to the passenger’s side front tire, and
repeat the procedure in Step 6.
8. Proceed to the passenger’s side rear tire, and
repeat the procedure in Step 6.
9. Proceed to the driver’s side rear tire, and
repeat the procedure in Step 6.
10. After hearing the conrming horn chirp for the
driver’s side rear tire, the tire learning process
ends. Turn the ignition switch to OFF.
11. Set all four tires to the recommended air
pressure level as indicated on the Tire
and Loading Information label.
12. Put the valve caps back on the valve stems.
The compact spare tire does not have a TPMS
sensor. If you replace one of the road tires with the
compact spare, the SERVICE TIRE MONITOR
SYSTEM message will be displayed on the DIC
screen. This message should go off once you
re-install the road tire containing the TPMS sensor.Federal Communications
