Pontiac 2007 Torrent - Manual (Page 396)

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.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a message to check
the pressure in a specific tire will appear on the
Driver Information Center (DIC) display. The
low tire pressure warning symbol on the instrument
panel cluster and the check tire pressure
message will appear at each ignition cycle until
the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can
be viewed by the driver. For additional information
and details about the DIC operation and displays
see DIC Operation and Displays on page 195
and DIC Warnings and Messages on page 200.
The low tire pressure warning light may come on in
cool weather when the vehicle is first started,
and then turn off as you start to drive. This may
be an early indicator that the air pressure in
the tire(s) are getting low and need to be inflated
to the proper pressure.
A Tire and Loading Information Label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct inflation
pressure for your vehicle’s tires when they are cold.
