Cadillac 2007 Automobile User Manual


 
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.
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.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to
function properly.
The CHECK TIRE PRESSURE warning message
and low tire pressure light (telltale) will come
on each time the vehicle is started 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 456.
For the location of the tire and loading information
label, see Loading Your Vehicle on page 366.
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 463 and Tires on page 450.
Notice: Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
