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 3-45 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 5-59 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 5-67 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
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.
