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.
Follow the TPMS sensor matching
process:
1. Set the parking brake.
2. Put the vehicle in ON/RUN and
place the vehicle in P (Park).
3. If the DIC display is minimized,
press the SELECT knob to
maximize it.
4. Use the SELECT knob to scroll
to the Tire Pressure display
screen.
5. Press and hold the SELECT
knob for five seconds to begin
the sensor matching process.
A message displays confirming
to begin the process.
6. Use the SELECT knob to
select YES with the highlighted
selection, and press the
SELECT knob again to
confirm the selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays
on the DIC screen.
7. Start with the driver side
front tire.
8. 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.
9. Proceed to the passenger
side front tire, and repeat the
procedure in Step 8.
10. Proceed to the passenger
side rear tire, and repeat the
procedure in Step 8.
11. Proceed to the driver side rear
tire, and repeat the procedure
in Step 8. The horn sounds two
times to indicate the sensor

rear tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
12. Turn the vehicle off.
