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 air-pressure out of a
tire you can 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 sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select
the Vehicle Information Menu in
the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to
the Tire Pressure Menu Item
screen.
5. Press the SET/CLR button to
begin the sensor matching
process.
A message asking if you are
sure you want to begin this
process should appear.
6. Press the SET/CLR button 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. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire's air pressure
for five seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to
30 seconds to sound, 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.
