Buick 2009 Enclave - Manual (Page 320)

• One or more TPMS sensors
are missing or damaged.
The DIC message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer/
retailer for service.
• Replacement tires or wheels do
not match your vehicle’s original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 5-51.
• Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer/retailer for
service if the TPMS malfunction light
and DIC message comes on and
stays on.
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.
