TPMS reset GMC ACADIA 2007 Owner's Manual

The Tire and Loading Information label (tire
information placard) shows the size of your
vehicle’s original tires and the correct ination
pressure for your vehicle’s tires when they are cold.
SeeInflation - Tire Pressure on page 442. For the
location of the tire and loading information label,
seeLoading Your Vehicle on page 361.
Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 448andTires on page 435.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identication codes 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 ination
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 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 sensor 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. If your vehicle
does not have the DIC buttons, press the trip
odometer reset stem located on the instrument
panel cluster until the RELEARN TIRE
POSITIONS message displays.
4. If your vehicle has the DIC buttons, press the
set/reset button. The horn sounds twice to
indicate the TPMS receiver is ready, and the
TIRE LEARNING ACTIVE message
displays. If your vehicle does not have the
DIC buttons, press and hold the trip odometer
reset stem until the horn chirps twice and
the TIRE LEARNING ACTIVE message
is displayed.
5. Start with the driver side front tire. The driver
side front turn signal lamp is on.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 to sound, conrms that the sensor
identication code has been matched to this
tire and wheel position.
7. Proceed to the passenger side front tire.
The passenger side front turn signal lamp is on.
Repeat the procedure in Step 6.
8. Proceed to the passenger side rear tire.
The passenger side rear turn signal lamp is on.
Repeat the procedure in Step 6.
9. Proceed to the driver side rear tire. The driver
side rear turn signal lamp is on. Repeat the
procedure in Step 6. Instead of a single horn
chirp a double horn chirp signals the TPMS
sensor has been matched to this tire and wheel
position and the matching process is no longer
active.
10. 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.
