TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
replace one or more of the TPMS
sensors or rotate your vehicle’s tires,
the identification 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 inflation pressure
indicated on the tire’s sidewall.
To decrease the tire’s air-pressure
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 matching process is
outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Go to the TPM vehicle
information screen on the DIC.
SeeDriver Information Center
(DIC) on page 4-27. Press set to
relearn the sensors. 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 stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for 10 seconds, or until a horn
chirp sounds. The horn chirp,
which can take up to 30 seconds
to sound, confirms that the TPMS
sensor identification code has
been matched to this tire 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.
8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5.
9. After hearing the confirming horn
chirp, for the driver side rear tire,
the horn sounds two more times
to signal the tire learning mode is
no longer active. Turn the ignition
switch to LOCK/OFF.

At your General Motors dealer/
retailer, you can be certain that
you will receive the highest level
of service available. Your dealer
/retailer has specially trained service
technicians, uses genuine GM
replacement parts, as well as, up to
date tools and equipment to ensure
fast and accurate diagnostics.
The proper replacement parts,
fluids, and lubricants to use are
listed inRecommended Fluids
and Lubricants on page 10-7and
Maintenance Replacement Parts on
page 10-9. We recommend the use
of genuine parts from your dealer/
retailer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires
on the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle,
it is important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). SeeTire
Rotation on page 9-61.Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter.
SeeEngine Oil on page 9-10.
An Emission Control Service.
When the Change Engine Oil
Soon message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and the
oil life system must be reset. Your
dealer/retailer has trained service
technicians who will perform this
work and reset the system.If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 miles since
the last service. Reset the oil life
system whenever the oil is changed.
SeeEngine Oil Life System on
page 9-13.
When the Change Engine Oil
Soon message displays, certain
services, checks, and inspections
are required. The services described
for MaintenanceIshould be
performed at every engine oil
change. The services described
for MaintenanceIIshould be
performed when:
•MaintenanceIwas performed
the last time the engine oil was
changed.
•It has been 10 months or more
since the Change Engine Oil
Soon message has displayed
or since the last service.
