Tire Pressure Monitor Operation - Pontiac G3 2009 Owner's Manual

Tire Pressure Monitor Operation

This vehicle may have a Tire Pressure Monitor
System (TPMS). The TPMS is designed to warn
the driver when a low tire pressure condition exists.
If your vehicle has this feature, the TPMS sensors
are mounted onto each tire and wheel assembly,
excluding the spare tire and wheel assembly.
The TPMS sensors monitor the air pressure in
your vehicle's tires and transmit tire pressure
readings to a receiver located in the vehicle.
The low tire pressure warning light comes on at each
ignition cycle until the tires are inflated to the correct
inflation pressure.
5-60
When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light on the instrument
panel cluster.
The 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 could be an early indicator that
the tire pressures 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. See Loading
the Vehicle on page 4-18, for an example of the tire
information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 5-57.
Your vehicle's TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. See Tire Inspection and Rotation
on page 5-62 and Tires on page 5-50.
Notice: Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not
covered by your warranty. Do not use liquid tire
sealants.
