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.
1
I
The engine oil dipstick is located directly behind the
engine fan.
Turn
off the engine and give the oil a few minutes to get
back down into the oil pan.
If you don't, the oil dipstick
might not show the actual level.

What Kind of Oil to Use:
Look for three things:
SG
“SG’ must be on the oil container, either by itself or
combined with other quality designations, such
as
“SG/CC,” “SG/CD,” “SF,SG,CC;” etc. These letters
show American Petroleum Institute (API) levels
of
quality.
I
0 SAE low-30 (V6 3.3L LG7 Engine)
As shown in this viscosity chart,
SAE 1OW-30 is
best for your vehicle. However, you can use SAE
5W-30
if it’s going to be colder than 60 OF ( 16 C)
before your next oil change. When it’s very cold,
below
O°F (-18 C), you should use SAE 5W-30.

thickness.
Energy Conserving I1
Oils with these words on the container will help you
save fuel.
This doughnut-shaped logo (symbol) is used on most oil
containers to help you select the correct oil.
You should look for this on the oil container, and use
only those oils that display the logo.
GM Goodwrench@ oil (in Canada,
GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives: Don't add anything to your oil.
Your Buick dealer is ready to advise if you think
something should be added.
When to Change Engine Oil: See if any one of these
is true for you:
Most trips are less than 4 miles (6 km).

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found
on the rear edge of the driver's door tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives you
important information about the number of people that
can be in your vehicle 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.

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.

Inflation - Tire Pressure I
I
I
The Tire-Loading Information label which is located on
the rear edge
of the driver’s door 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.
overinflation is all right. it’s not. If your tires d
have enough air (underinflation) you can get:
0 Too much flexin
0 Too much heat

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.
x
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, Buick
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.
