Tire Pressure Light
For vehicles with a tire
pressure monitoring
system, this light comes
on briefly when the engine
is started.
It 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 5-53 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 5-62
for more information.
