EMISSION CONTROL SYSTEM MAINTENANCE
The “Scheduled” maintenance services, listed inbold
typeon the following pages must be done at the times or
mileages specified to assure the continued proper func-
tioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions such as dusty
areas and very short trip driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
EMISSIONS TESTING
In some localities, it may be or will become a legal
requirement to ensure that all emissions components and
systems are functioning properly as a part of the test
procedure. The test center accomplishes this by checking
the On Board Diagnostic System (OBD) system with an
electronic scan tool. If your vehicle has recently been
serviced, the OBD system may have been reset to anot
readycondition because the OBD system has not had
sufficient time since the servicing to reconfirm that
emissions components are operating properly. In most
cases, a reasonable mix and amount of normal city and
highway driving and at least one overnight-off period
will be required to prepare your vehicle for this check;
however your dealer has the equipment and procedures
required to make certain that the OBD system of your
vehicle is ready for the required testing.
