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.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press the Remote Keyless
Entry (RKE) transmitter’s LOCK
and UNLOCK buttons at the
same time for approximately
five seconds. 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 cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for five seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, confirms that the sensor
identification code has been
matched to this tire and wheel
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. The horn sounds
two times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to
LOCK/OFF.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.
