Downloaded from www.Manualslib.com manuals search engine Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood
to relieve pressure on the
hood prop.
Remove the hood prop
from the slot in the hood and
return the prop to
its retainer.
Then just pull the hood down firmly
to close. It will
latch when dropped from
10 to12 inches (25 to 30 cm)
without pressing
on the hood.
Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The oil dipstick is
a
yellow ring.
Turn
off the engine and
give the oil a few minutes
to drain back into the oil
pan.
If you don’t, the oil
dipstick might not show
the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or,
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD line, then you’ll
need to add some oil. But you must use the right kind.
This part explains what kind of
oil to use. For crankcase
capacity, see “Capacities and Specifications” in
the Index.

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your

you can use SAE IOW-30 if it’s going
to be
0°F (- 1 SOC) or above. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity

NOTICE:
Use only engine oil with the American Petroleum

Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked when your tires are cold.
Overinflated tires are more likely
to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread
is badly worn, or if your tires have
been damaged, replace them.
Inflation - Tire Pressure
The Certificationmire label which is on the driver’s door
edge, above the door latch, shows the correct inflation
pressures for your tires
when they’re cold. “Cold”
means your vehicle has been sitting for
at least three
hours or driven
no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
Too much heat
0 Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.

Downloaded from www.Manualslib.com manuals search engine Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material
to the parts repaired or
replaced
to restore corrosion protection.
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 occurs first.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized v
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.
Performing maintenance work on a vehicle can
be dangerous. In trying
to do some jobs, you can
be seriously injured. Do your own maintenance
work only if you have the required know-how
and the proper tools and equipment for the
job.
If you have any doubt, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle,
you will probably want to get the service
information
GM publishes. See “Service and Owner
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.

Services
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 bow 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 your
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.

driving limits.
0 are driven off-road in the recommended manner. See

Vehicle’’ in the Index.
use the recommended fuel. See “Fuel” in the Index.
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:
