Appearance Care
Cleaning products can be hazardous. Some are toxic.
Other cleaning products can burst into ames if a match
is struck near them or if they get on a hot part of the
vehicle. Some are dangerous if their fumes are inhaled
in an enclosed space. When anything from a container
is used to clean the vehicle, be sure to follow the
manufacturer’s warnings and instructions. Always open
the doors or windows of the vehicle when cleaning
the inside.
Never use these to clean the vehicle:
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous — some more than
others —and they can all damage the vehicle, too.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
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible.
Your vehicle’s interior may experience extremes of heat
that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.

Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be used
on oor carpet and carpeted oor mats. For soils, always
try to remove them rst with plain water or club soda.
Before cleaning, gently remove as much of the soil as
possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.If any of the soil remains, a commercial fabric cleaner or
spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test a
small hidden area for colorfastness rst. If the locally
cleaned area gives any impression that a ring formation
may result, clean the entire surface.
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
Leather
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a soft cloth dampened with a mild soap solution can
be used. Allow the leather to dry naturally. Do not use
heat to dry. Never use steam to clean leather. Never
use spot lifters or spot removers on leather. Many
commercial leather cleaners and coatings that are sold
to preserve and protect leather may permanently
change the appearance and feel of your leather and are
not recommended. Do not use silicone or wax-based
products, or those containing organic solvents to clean
your vehicle’s interior because they can alter the
appearance by increasing the gloss in a non-uniform
manner. Never use shoe polish on your leather.

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
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids 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. All recommended maintenance is
important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper uid
levels or the wrong tire ination 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.
Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do not know
exactly how you will drive it. You may drive very
short distances only a few times a week. Or you may
drive long distances all the time in very hot, dusty
weather. You may use your vehicle in making deliveries.
Or you may drive it to work, to do errands or in many
other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your GM Goodwrench
®dealer.

Scheduled Maintenance
When the CHANGE ENGINE OIL message in the Driver
Information Center (DIC) comes on, it means that service
is required for your vehicle. Have your vehicle serviced as
soon as possible within the next 600 miles (1 000 km). It
is possible that, if you are driving under the best
conditions, the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
your engine oil and lter must be changed at least once a
year and at this time the system must be reset. Your GM
Goodwrench
®dealer has GM-trained service technicians
who will perform this work using genuine GM parts and
reset the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-17for information on
the Engine Oil Life System and resetting the system.When the change engine oil message appears, certain
services, checks, and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally,
it is recommended that your rst service be
MaintenanceI, your second service be MaintenanceII,
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceI— Use MaintenanceIif the change
engine oil message comes on within 10 months since
the vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
