Tyre Inspection - Cadillac XT4 Owner's Manual

tyre with a road tyre 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 tyre/wheel
positions, using a TPMS relearn tool,
in the following order: driver side
front tyre, passenger side front tyre,
passenger side rear tyre, and driver
side rear tyre. See your dealer for
service or to purchase a relearn tool.
You have two minutes to match the
first tyre/wheel position, and
five minutes overall to match all four
tyre/wheel positions. If it takes longer,
the matching process stops and must
be restarted.
The TPMS sensor matching process is
outlined below:
1. Apply the parking brake.
2. Place the vehicle in Service Mode.
See Ignition Positions 0 205.
3. Make sure the Tyre Pressure info
display option is turned on. The
info displays on the DIC can be
turned on and off through the
Options menu. See Driver
Information Centre (DIC) 0 115.
4. Use the DIC controls on the
right-hand side of the steering
wheel to scroll to the Tyre Pressure
screen under the DIC info page.
5. Press and hold the thumbwheel
located in the centre of the DIC
controls on the right-hand side of
the steering wheel.
The horn sounds twice to signal
the receiver is in relearn mode and
the TYRE LEARNING ACTIVE
message displays on the DIC
screen.
6. Start with the driver side front tyre.
7. Place the relearn tool against the
tyre 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 tyre and wheel
position.
8. Proceed to the passenger side front
tyre, and repeat the procedure in
Step 7.
9. Proceed to the passenger side rear
tyre, and repeat the procedure in
Step 7.
VEHICLE CARE

The horn sounds two times to

driver side rear tyre, and the TPMS
sensor matching process is no
longer active. The TYRE LEARNING
ACTIVE message on the DIC
display screen goes off.
11. Turn the vehicle off.
12. Set all four tyres to the
recommended air pressure level as
indicated on the Tyre and Loading
