Cadillac GMC Yukon Denali 2005, Owner'S Manual

Page: 364 / 456

When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle’s tire information placard. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability. Each tire,
including the spare, should be checked monthly when
cold and set to the recommended inflation pressure as
specified in the vehicle placard and owner’s manual.
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 4-43.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation on
page 5-66 and Tires on page 5-56.
Notice: Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
TPM Sensor Identification Codes
Each TPM sensor has a unique identification code. Any
time you rotate your vehicle’s tires or replace one or
more of the TPM 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: left front (LF); right front (RF);
right rear (RR) and left rear (LR).
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.
