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 properly, it cannot detect
or signal a low tire condition. See your dealer 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.
The identification code needs to be matched to a new
tire/wheel position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors. Also, the
TPMS sensor matching process should be performed
after replacing a spare tire with a road tire containing
the TPMS sensor. The malfunction light and the DIC
message should go off at the next ignition cycle. The
sensors are matched to the tire/wheel positions, using a
TPMS relearn tool, in the following order: driver side
front tire, passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for service or
to purchase a relearn tool.

There are two minutes to match the first tire/wheel
position, and five minutes overall to match all four tire/
wheel positions. If it takes longer, the matching process
stops and must be restarted.

The TPMS sensor matching process is:

1. Set the parking brake.

2. Turn the ignition 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. Place the relearn tool against the tire sidewall,

near the valve stem. Then press the button to
activate the TPMS sensor. A horn chirp 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sensor matching process is no longer active.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.
