ANY OTHER GRAOE OIL NOT RECOMMENOEO DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
If your vehicle has the 3.1 L engine, as shown in the
chart, SAE
5W-30 is best for your vehicle. However,
you can use SAE
low-30 if it’s going to be 0°F
(- 18 “C) or above. These numbers on an oil container
show its viscosity, or thickness.
Do not use other
viscosity
oils, such as SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with the new “starburst” symbol
on the front of
the container, you should look for and
use oils containing the following three things:

“SH” or “SG” must be on the oil container, either by
itself or combined with other quality designations,
such as “SH/CD,” “SH,SG,CD,” “SG/CD” etc.
These letters show American Petroleum Institute
(API) levels of quality.

and the total weight that you can carry. This weight is
called the Vehicle Capacity Weight and includes the weight of all occupants, cargo, and all
nonfactory-installed options. And, if you do have a heavy load, you should spread it
out. Don’t carry more than
167 pounds (76 kilograms)
in your trunk.

The other label is the Certification label, found on the
rear edge of the driver’s door. It tells
you the gross
weight capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front
or rear
axle.
If you put things inside your vehicle - like suitcases,
tools, packages, or anything else
- they will go as fast
as the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they’ll keep going.

Your warranty does not cover parts or
components that fail because of overloading.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the deck lid
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:
0 Too much flexing
Too much heat
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get:
Unusual wear
0 Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60
psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell
you the
pressure, especially
if you have radial tires -- which
may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back
on. They help prevent leaks by keeping out dirt and
moisture.

Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish if they remain on painted
surfaces. Use cleaners that are marked safe for painted
surfaces to remove foreign matter.
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.

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 sigHificantly
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.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section
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.
“Section 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.
“Section C: Periodic Maintenance Inspections” explains important inspections that your Buick dealer’s service
department or another qualified service center should perform.
