GM Goodwrench®oil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you will need for good performance
and engine protection.
When to Change Engine Oil
If any one of these is true for you, use the short trip/city
maintenance schedule:
•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.
•You frequently tow a trailer or use a carrier on top
of your vehicle.
•The vehicle is used for delivery service, police, taxi,
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles (5 000 km) or 3 months — whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change oil and filter every
7,500 miles (12 500 km) or 12 months — whichever
occurs first. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil to
break down slower.

What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located in the engine
compartment on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12
for more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the engine air cleaner/filter every 15,000 miles
(25 000 km) and replace every 30,000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the engine air cleaner/filter remove the filter
from the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt, a
new filter is required.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. If a
leak occurs, take the vehicle to the dealership service
department and have it repaired as soon as possible.
You may also have your fluid level checked by
your dealer or service center when you have your
oil changed.
Notice:Use of automatic transaxle uid labeled
other than ESSO LT71141 or TOTAL ATF H50235
may damage your vehicle, and the damages may not
be covered by your warranty. Always use
ESSO LT71141 or TOTAL ATF H50235 labeled
automatic transaxle uid.
Manual Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. SeePart D: Recommended Fluids and
Lubricants on page 6-24for the proper fluid to use.
Hydraulic Clutch
There is one reservoir for both the brake and the
hydraulic clutch fluid. SeeBrakes on page 5-30for
more information.
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir is filled with
hydraulic fluid.
It is not necessary to regularly check the fluid unless
you suspect there is a leak in the system. Adding fluid
will not correct a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your master
cylinder reservoir and for the proper fluid. See
Part B: Owner Checks and Services on page 6-18and
Part D: Recommended Fluids and Lubricants on
page 6-24.

Do not use any of these products unless this manual
says you can. In many uses, these will damage
the vehicle:
•Alcohol
•Laundry Soap
•Bleach
•Reducing Agents
Fabric/Carpet
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl, leather, plastic, and painted surfaces
with a clean, damp cloth.
GM-approved cleaning products can be obtained from
your dealer.
Here are some cleaning tips:
•Always read the instructions on the cleaner label.
•Clean up stains as soon as you can before they set.
•Carefully scrape off any excess stain.
•Use a clean cloth or sponge, and change to a clean
area often. A soft brush may be used if stains are
stubborn.
•To avoid forming a ring on the fabric after spot
cleaning, clean the entire area immediately or it
will set.Most stains can be removed with club soda water. To
clean, use the following instructions:
1. For liquids: blot with a clean, soft, white cloth. For
solids: remove as much as possible and then
vacuum or brush.
2. Apply club soda water to a clean, soft, white cloth.
Do not over-saturate; the cloth should not drip water.
3. Clean the entire area. Avoid getting the fabric
too wet.
4. Start cleaning from the seams into the stain to
avoid a ring effect.
5. Continue cleaning, using a clean area of the cloth
each time it becomes soiled.
6. When the stain is removed, blot the cleaned area
with another dry, clean, soft, white cloth.
Using Cleaner on Fabric
1. First, try the cleaner on an area of the fabric that is
not easily seen to make sure the cleaner does not
affect the color of the fabric.
2. For liquids: blot with a clean, soft, white cloth. For
solids: remove as much as possible and then
vacuum or brush.
3. Spray a small amount of the cleaner onto a clean
soft, white, cloth. Do not apply spray directly to
the fabric.

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
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. Cooling

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 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 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. Cooling
System Service. EVAP System Service. PCV System
Service. Timing Belt Inspection. Brake/Clutch Fluid
Change (or 24 months, whichever occurs first).
Every 60,000 Miles (100 000 km):Spark Plug Wire
Replacement. Timing Belt Replacement. EVAP System
Solenoid Valve Filter Replacement.Every 90,000 Miles (150 000 km):Fuel Filter
Replacement.
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.

andPart C: Periodic Maintenance Inspections on
page 6-22.
Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that 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.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-23.
