TPMS Matching Process for Vehicles
without Remote Keyless Entry (RKE)
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Using the Driver Information Center (DIC), press the
INFO and Set/Reset buttons at the same time for
about one second. Then press and release the INFO
button until the TIRE LEARN? message displays.
4. Press and hold the Set/Reset DIC button for
approximately three seconds to start the TPMS
learn mode. The horn sounds twice to indicate the
TPMS receiver is ready and the TIRE LEARN
ON message displays. The driver side front turn
signal also comes on to indicate that corner sensor
is ready to be learned.
5. Start with the driver side front tire.
6. Remove the valve cap from the tire's valve stem.
Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm
the sensor identification code has been matched to
the tire/wheel position.
7. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and repeat
the procedure in Step 6.
8. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and repeat
the procedure in Step 6.
9. The driver side rear turn signal comes on to indicate
that corner sensor is ready to be learned. Proceed to
the driver side rear tire, and repeat the procedure
in Step 6.
10. After hearing the single horn chirp for the driver side
rear tire, two additional horn chirps sound to indicate
the tire learning process is done. The LEARN
COMPLETE message displays if all four tire
positions are learned. Turn the ignition switch to
LOCK/OFF.
If no tires are learned after entering the TPMS learn
mode, or if communication with the receiver stops,
or if the time limit has expired, the TIRE LEARN?
message displays on the DIC. Turn the ignition switch
to LOCK/OFF and start over beginning with Step 2.
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.
