Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted on each tire and wheel assembly,
except for the compact spare tire and wheel. The
TPMS sensors monitor the air pressure in your
vehicle’s tires and transmit the tire pressure
readings to a receiver located in the vehicle. The
TPMS is designed to alert the driver if a low
pressure condition exists.
Using the Driver Information Center (DIC), the
driver can also check tire pressure levels using the
DIC. For additional information and details about
the DIC operation and displays seeDIC Controls
and Displays on page 215andDIC Warnings
and Messages on page 220.When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
symbol located in the instrument panel cluster,
and at the same time a DIC message to check the
pressure in a specic tire also appears on the
DIC display. The low tire pressure warning symbol
and the CHECK TIRE PRESSURE message on
the DIC display appear at each ignition cycle until
the tires are inated to the correct ination
pressure.
You may notice, during cooler weather conditions,
the low tire pressure warning light and DIC
warning message may come on when the vehicle
is rst started, and then turn off as you start to
drive. This could be an early indicator that the air
pressure in the tire(s) is getting low and needs
to be inated to the proper pressure.

The TPM matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Using the DIC, press the vehicle information
button until the PRESS
VTO RELEARN
TIRE POSITIONS message displays.
4. Press the Set/Reset button. The horn sounds
twice to indicate the TPMS receiver is ready,
and the TIRE LEARNING ACTIVE message
displays. The TPMS low tire warning light
ashes throughout the matching procedure.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for
10 seconds, or until a horn chirp sounds. The
horn chirp, which may take up to 30 seconds to
sound, 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.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 horn sounds
two more times to signal the tire learning
model is no longer active. 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 spare tire does not have a TPMS sensor.
If you replace one of the road tires with the spare,
the SERVICE TIRE MONITOR SYSTEM
message displays on the DIC screen. This
message should go off once you re-install the
road tire containing the TPMS sensor.

Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the
vehicle moves, you or others could be
injured.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake. SeeParking
Brake on page 127.
Be ready to apply the regular brake
immediately if the vehicle begins to move.3. With the engine off, turn the ignition to ON,
but do not start the engine. Without applying
the regular brake, try to move the shift
lever out of PARK (P) with normal effort. If the
shift lever moves out of PARK (P), contact
your GM Goodwrench
®dealer for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try
to turn the ignition to OFF in each shift lever
position.
The ignition should turn to OFF only when the
shift lever is in PARK (P).
The ignition key should come out only in OFF.
Contact your GM Goodwrench
®dealer if service
is required.
