EMISSION CONTROL SYSTEM MAINTENANCE
The “Scheduled” maintenance services, listed in bold
type must be done at the times or mileages specified to
assure the continued proper functioning 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 main-
tenance 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
emission control devices and systems on your vehicle
may be performed by any automotive repair establish-
ment or individual using any automotive part which has
been certified pursuant to U.S. EPA or, in the State of
California, California Air Resources Board regulations.
