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 3-73 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 5-48 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 5-60
for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of 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.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
