GMC Yukon Denali 2006 Manual page 378

Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
The CHECK TIRE PRESSURE warning message and
low tire pressure light (telltale) will appear at each
ignition cycle until the tires are inflated to the correct
inflation pressure.
The Tire and Loading Information label (tire information
placard) shows the size of your vehicle's original
tires and the correct inflation pressure for your vehicle's
tires when they are cold. See Inflation - Tire Pressure
on page 5-62. For the location of the tire and loading
information label, see Loading Your Vehicle on
page 4-44.
Your vehicle's TPMS can alert you about a low tire
pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation on
page 5-68 and Tires on page 5-55.
Notice: Do not use a tire sealant if your vehicle has
Tire Pressure Monitors. The liquid sealant can
damage the tire pressure monitor sensors.

Resetting the TPMS Identification Codes
Each TPMS sensor has a unique identification code. Any
time you rotate your vehicle's tires or replace one or more
of the TPMS sensors, the identification codes will need to
be matched to the new tire/wheel position. Each tire/
wheel position is matched to a sensor, by increasing or
decreasing the tire's air pressure. The sensors are
matched to the tire/wheel positions in the following order:
LF TIRE (left front tire on the driver's side of the vehicle),
RF TIRE (right front tire on the passengers side of the
vehicle), RR TIRE (right rear tire on the passengers side
of the vehicle), and LR TIRE (left rear tire on the driver's
side of the vehicle).
You will have one minute to match the first tire/
wheel position, and five minutes overall to match all
four tire/wheel positions. If it takes longer than one
minute, 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 will need to start over.
