GENERAL INFORMATION
INTRODUCTION
There are two maintenance schedules that show
proper service intervals for ZJ vehicles. Use the
schedule that best describes the conditions the vehi-
cle is operated under. When mileage and time is
listed, follow the interval that occurs first.
Schedule-A lists all the scheduled maintenance to
be performed under normal operating conditions.
Schedule-B is a schedule for vehicles that are
usually operated under one or more of the following
conditions:
• Frequent short trips driving less than 5 miles (8
km)
• Frequent driving in dusty conditions
• Frequent trailer towing
• Extensive idling
• More than 50% of your driving is at sustained
high speeds during hot weather, above 90°F (32°C)
• Off road driving
• Desert operation
EMISSION CONTROL SYSTEM MAINTENANCE
The scheduled emission maintenance listed in bold
type on the Maintenance Schedules, must be done at
the mileage 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 the best vehicle
performance and reliability. More frequent mainte-
nance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
