EMISSION CONTROL SYSTEM MAINTENANCE
The “Scheduled” maintenance services, listed inbold
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 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.
MAINTENANCE SCHEDULES — GASOLINE
ENGINES
There are two maintenance schedules that show the
required service for your vehicle.

engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow “Schedule B” of the
“Maintenance Schedules” section of this manual.
NOTE: IfANY of these apply to you then flush and
replace your engine coolant/anti-freeze every 102,000
miles (170 000 km) or 60 months, whichever comes first,
and follow “Schedule B” of the “Maintenance Schedules”
section of this manual.
NOTE: Most vehicles are operated under the conditions
listed for Schedule “B.” Second is Schedule
“A”. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule “B.”
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
