Buick 2009 Enclave - Manual (Page 321)

The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch 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. 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.
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matching process is no longer
active.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.
9. Turn the ignition switch to
LOCK/OFF.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.
Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare
tire, if the vehicle has one, for
signs of wear or damage.
See When It Is Time for New
Tires on page 5-51 for more
information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km). See
Scheduled Maintenance on
page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the
vehicle. This will ensure that the
vehicle continues to perform
most like it did when the
tires were new.
