Tire Pressure Light
The tire pressure light should come

If it does not, have the vehicle
service by your dealer/retailer.
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 are signicantly
underinated.
A tire pressure message in the
Driver Information Center (DIC),
may accompany the light.SeeDIC Warnings and Messages
on page 3-56for more information.
Stop and check the tires as
soon as it is safe to do so.
If underinated, inate to the

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 comes 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.
