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. Place the vehicle power mode in
ON/RUN/START. See Ignition
Positions on page 9 18.
3. Select the vehicle information
menu using the menu button.
4. Select the tire pressure screen
using the up/down thumbwheel.
5. Press and hold SET to begin the
sensor matching process.
6. Press SET to confirm selection.
The horn sounds twice to signal
the receiver is in relearn mode
and 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

side rear tire, and the TPMS
sensor matching process is

on the DIC display screen
goes off.
