Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
. The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in ON/
RUN and the light is not on.
. The vehicle will not pass this
inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would be
considered not ready for
inspection. This can happen if
the battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer/
retailer can prepare the vehicle
for inspection.
Brake System Warning
Light
This vehicle's hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking both
parts need to be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.

This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
This light may also come on due to
low brake fluid. See Brakes on
page 10‑21 for more information.
