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. 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 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is no longer active.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.
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.
