Scheduled Maintenance

7-5
Short Trip/City Definition
Follow the Short Trip/City Scheduled Maintenance if
any one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop
-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break 
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km): Engine Oil and Filter
Change (or 3 months, whichever occurs first). Chassis
Lubrication (or 3 months, whichever occurs first).
Drive Axle Service (or 3 months, whichever 
occurs first).
Every 6,000 Miles (10 000 km): Tire Rotation.
Every 15,000 Miles (25 000 km): Engine Air Cleaner
Filter Inspection, if driving in dusty conditions.
Gasoline Engine Only: Noise Shields Inspection
(GVWR above 10,000 lbs. only). Diesel Engine Only:
Shields and Underhood Insulation Inspection. Diesel
Engine Only: Thermostatically Controlled Engine
Cooling Fan Check (or every 12 months, whichever
occurs first). Diesel Engine Only: Air Intake System
Inspection. Front Wheel Bearing Repack (or at each
brake relining, whichever occurs first).
Every 24,000 Miles (40 000 km): Diesel Engine Only:
Fuel Cap Replacement, if driving in dusty conditions.

Filter Replacement. Fuel Filter Replacement.
Every 50,000 Miles (83 000 km): Automatic

or driven under severe conditions or equipped with

Long Trip/Highway Definition
Follow this scheduled maintenance only if none of 
the conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is used for trailer towing, driven in a dusty area
or used off paved roads. Use the Short Trip/City
schedule for these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions causes engine oil to break 
down slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every 12 months, whichever occurs first).
Chassis Lubrication (or every 12 months, whichever
occurs first). Drive Axle Service. Tire Rotation.
Every 15,000 Miles (25 000 km): Gasoline Engine
Only: Noise Shields Inspection (GVWR above 
10,000 lbs. only). Diesel Engine Only: Shields and
Underhood Insulation Inspection. Diesel Engine Only:
Thermostatically Controlled Engine Cooling Fan Check
(or every 12 months, whichever occurs first). Diesel
Engine Only: Air Intake System Inspection.
Every 30,000 Miles (50 000 km): Fuel Filter
Replacement. Engine Air Cleaner Filter Replacement.
Front Wheel Bearing Repack (or at each brake
relining, whichever occurs first).
Every 50,000 Miles (83 000 km): Automatic
Transmission Service (vehicles over 8600 GVWR 
or driven under severe conditions or equipped with
diesel engine).
