Tire Pressure Monitor System - Cadillac 2005 SRX Owner's Manual

Tire Pressure Monitor System

Your vehicle may have this feature. The Tire Pressure
Monitor (TPM) system uses radio and sensor technology
to check tire pressure levels. If your vehicle has this
feature, sensors are mounted on each tire and wheel
assembly, except for the compact spare tire and wheel.
Tire pressure readings are sent to a receiver located
in the vehicle once every 60 seconds while the vehicle is
being driven, and once every 60 minutes if the vehicle
is stationary for more than 15 minutes.
Using the Driver Information Center (DIC), tire pressure
levels can be viewed by the driver. For additional
information and details about the DIC operation and
displays see System Controls on page 3-48 and
DIC Warnings and Messages on page 3-57. When a
low tire pressure condition is detected, the TPM system
will display the CHECK TIRE PRESSURE warning
message on the Driver Information Center (DIC) and, at
the same time, illuminate the low tire pressure warning
symbol, on the instrument panel cluster.
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 (your vehicle's
tire information placard) shows the size of your
vehicle's original tires and their recommended cold
inflation pressures. See Loading Your Vehicle on
page 4-45, for the location of the tire and loading
information label. Also see Inflation - Tire Pressure on
page 5-58.
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 5-63 and Tires on page 5-52.
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.
