Tire Pressure Monitor Operation - Chevrolet 2008 Cobalt Owner's Manual

Tire Pressure Monitor Operation

The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. 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 the vehicle's tires and transmits the tire pressure
readings to a receiver located in the vehicle.
At the same time a message to check the pressure
in a specific tire appears on the Driver Information
Center (DIC) display. The low tire pressure warning
light and the DIC warning message come on 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 3-40
and DIC Warnings and Messages on page 3-43.
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 could 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 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 Your Vehicle on page 4-27, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also see Inflation - Tire
Pressure on page 5-56.
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 5-63 and Tires on page 5-49.
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.
