engine CHEVROLET AVEO 2008 1.G Owners Manual

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your
dealer/retailer for details.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in
this manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure to
follow scheduled maintenance may not be covered
by warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. Improper vehicle maintenance can
even affect the quality of the air we breathe. Improper
fluid levels or the wrong tire inflation can increase
the level of emissions from your vehicle. To help protect
our environment, and to keep your vehicle in good
condition, be sure to maintain your vehicle properly.
6-2

Selecting the Right Schedule
First you will need to decide which of the two schedules
is right for your vehicle. Here is how to decide which
schedule to follow:
Short Trip/City Denition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
•Most trips are less than 5 miles (8 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.
•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).
Every 6,000 Miles (10 000 km):Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Passenger Compartment Air Filter
Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Spark Plug Replacement. EVAP
System Service. PCV System Service.
Every 37,500 Miles (60 000 km):Automatic
Transmission Fluid Change (severe service only).
Every 42,000 Miles (70 000 km):Engine Oil Pan Drain
Plug Washer Replacement.
Every 60,000 Miles (100 000 km):Spark Plug Wire
Replacement. Timing Belt Replacement. EVAP System
Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement.
Every 150,000 Miles (240 000 km):Cooling System
Service.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
6-5

Long Trip/Highway Denition
Follow this scheduled maintenanceonlyif none of
the conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is 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 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Passenger Compartment Air Filter
Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Spark Plug Replacement. EVAP
System Service. PCV System Service.
Every 37,500 Miles (60 000 km):Automatic
Transmission Fluid Change (severe service only).Every 60,000 Miles (100 000 km):Spark Plug Wire
Replacement. Timing Belt Replacement. EVAP System
Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement. Engine Oil Pan Drain Plug Washer
Replacement.
Every 150,000 Miles (240 000 km):Cooling System
Service.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to
100,000 miles (166 000 km) should be repeated after
100,000 miles (166 000 km) at the same intervals
for the life of this vehicle. The services shown at
150,000 miles (240 000 km) should be repeated at
the same interval after 150,000 miles (240 000 km)
for the life of this vehicle.

the failure to perform this maintenance item will
not nullify the emission warranty or limit recall liability
prior to the completion of the vehicle’s useful life.
We, however, urge that all recommended maintenance
services be performed at the indicated intervals and
the maintenance be recorded.
