Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
Follow the Short Trip/City Scheduled Maintenance
if any
one of these conditions is true for your vehicle:
0 Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
0 Most trips include extensive idling (such as frequent
0 You frequently tow a trailer or use a carrier on top
driving in
stop-and-go traffic).
of your vehicle.
0 If the vehicle is used for delivery service, police,
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.
taxi or other commercial application.
Short TriplCity Intervals
Every 3,000 Miles (5 000 km): Engine Oil and Filter
Change (or
3 months, whichever occurs first).
Every 6,000 Miles (IO 000 km): Tire Rotation.
Every 15,000 Miles (25 000 km): Engine Air Cleaner
Filter Inspection,
if driving in dusty conditions.
Every 30,000 Miles (50 000 km): Engine Air Cleaner
Filter Replacement. Supercharger Oil Check
(or every
36 months, whichever occurs first)
(3800 Code 1 V6 engine only).
Every 50,000 Miles (83 000 km): Automatic Transaxle
Service (severe conditions only).
Every 100,000 Miles (166 000 km): Spark Plug Wire
Inspection. Spark Plug Replacement. Automatic

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 will cause 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). Tire Rotation.
Every 30,000 Miles (50 000 km): Supercharger Oil

this vehicle. The services shown at 150,000 miles

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear.
Do not lubricate accelerator
and cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. You may need to
have your brakes inspected more often
if your driving
habits or conditions result in frequent braking.
