Every now and then have your dealership check your air conditioning
system to be sure it has not lost any cooling ability. If you think\
the system
is not working properly, have your dealership check it out as \
soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4°C).
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine how often to lubricate them
and what type
of lubricant to use.
You should not
use penetrating oils because they could wash out me factory
installed lubricant and cause the lock to bind. De-icers which \
contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
0 Engine misfiring
0 Loss of performance
0 Exhaust system components hanging lower than normal.
0 Loud exhaust system noises.
0 Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce \
the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel
in your vehicle. If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear is present, rotate your tires as
soon as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When It’s Time for New Tires” and “Wheel Replacement”
later in this section for more information.
The purpose of regular rotation is to achieve more uniform wear for all tires
on the vehicle. The first rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled rotation intervals.

FRT When
rotating your
tires, always use one of the correct rotation
patterns shown here.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the Certificatioflire label. Make certain that
all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.

Downloaded from www.Manualslib.com manuals search engine Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and may develop into a major
repair expense.
Minor chips and scratches can be repaired with touch-up materials available
from your dealer or other service outlets. Larger areas of finish damage can
be corrected in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust control can collect on
the underbody. If these are not removed, accelerated corrosion (rust) can
occur on the underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion protection.
At least every spring, flush these materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt packed
in closed areas of the frame should be loosened before being flushed. Your
dealer or an underbody vehicle washing system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a chemical fallout.
Airborne pollutants can fall upon and attack painted surfaces on your
vehicle. This damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into the paint surface.
Although no defect in the paint
job causes this, GM will repair, at no charge
to the owner, the surfaces of new vehicles damaged by this fallout condition
within
12 months or 12,000 miles (20 000 km) of purchase, whichever
comes first.

to retain its safety, dependability and emission control

Introduction
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 procedures are important. Improper vehicle maintenance
or the
removal
of important components can significantly affect the quality of the
air we breathe. Improper fluid levels or even the wrong tire inflation can
increase the level of emissions from your vehicle. To help protect our
environment, and to help keep your vehicle
in good condition, please
maintain your vehicle properly.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows what to have done and
how often. Some
of these services can be complex, so unless you are
technically qualified and have the necessary equipment, you should let your
dealer’s service department
or another qualified service center do these jobs.
If you are skilled enough to do some work on your vehicle, you will
probably want to get the service information
GM publishes. You will find a
list of publications and how to get them in this manual. See “Service
Publications” in the Index.
“Part B: Owner Checks and Services” tells you what should be checked
whenever
you stop for fuel. It also explains what you can easily do to help
keep your vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains important
inspections that your
GM dealer’s service department or another qualified
service center should perform.
“Part D: Recommended Fluids and Lubricants” lists some products GM
recommends to help keep your vehicle properly maintained. These \
products,
or their equivalents, should be used whether you do the work yourself or
have it done.
“Part E: Maintenance Record’ provides a place for you to record the
maintenance performed on your vehicle. Whenever any maintenance is
performed, be sure to write it down
in this part. This will help you
determine when your next maintenance should be done. In addition, it is a
good idea to keep your maintenance receipts. They may be needed to
qualify your vehicle
for warranty repairs.

Using Your Maintenance Schedule
We at General Motors want to help you keep your vehicle in good working
condition. But we don’t know exactly how you’ll 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 GM vehicles, maintenance
needs
vary. You may even need more frequent checks and replacements than
you’ll find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how to keep your vehicle
in good condition, see you GM dealer.
This part tells you the maintenance services
you should have done and when
you should schedule them. If you
go to your dealer for your service needs,
you’ll know that GM-trained and supported service people will\
perform the
work using genuine GM parts.
The proper fluids and lubricants to use are listed in Part
D. Make sure
whoever services your vehicle uses these. All parts should be \
replaced and
all necessary repairs done before you or anyone else drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended limits. You will find
these limits on your vehicle’s CertificationEire label. See “Loading
Your Vehicle’’
in the Index.
are driven on reasonable road surfaces within legal driving limits.
are driven off-road in the recommended manner. See “Off Road
Driving With Your Four-wheel Drive Vehicle” in the Index.
use the recommended unleaded fuel. See “Fuel” in the Index.

vehicle. Here’s how to decide which schedule to follow:
