Tire Pressure Light
For vehicles with a tire
pressure light, this light
comes on briefly when the
engine is started and
provides information about
tire pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is significantly
underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. See DIC
Warnings and Messages on page 3-50 for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinflated, inflate to the
proper pressure. See Tires on page 5-51 for more
information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. See Tire Pressure Monitor System on page 5-61
for more information.

the fuel, ignition, and emission control systems. It
ensures that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
