Your vehicle may have 2 3800 Sqercharged engine.
Supercharging, rather
than turbocharging, emphasizes
smooth, refined power.
The supercharger is a device which is designed to pump
more ais into the engine than it would normally use.
This air mixed with fuel creates increased engine power.
Since the supercharger
is a pump and is driven from an
engine
accessory drive belt, iwreased pressure is
available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light tfarsttIe cruising, the excess air that the
supercharger is pumping is routed through a bypass.
AB1 sf these controk working together provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
The power steering pump and reservoir are mounted on
the rear (driver’s side) sf the engine biock. See
“Maintenance Schedule”
in the Index for when you
should check the fluid.

ENGINE OIL LOW CHECK LEVEL HMBHBMrn
Ef you have the Driver Infcmation Center, an ENGINE
OIL LOW-CHECK LEVEL message will appear when
the engine oil is approximately I quart (fL) Isw. 11 the
message is displayed, check the dipstick level and add
oil as needed.

Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids
md Eubricmts” in the Index.
If the fluid level is low, add only enough of the proper
fluid
to bring the level into the cross-hatched area on
the dipstick.
I. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole
to bring it to the proper level.
It doesn’t
take much fluid, generally less than one

(0.5 L). Don’t ove@Zl.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 MI0 h) whichever occurs first, if you add only
DEX-COOL“ extended life coolant,
The following explains
your coding system and
how to add coolant when it is low. If YOU have a
problem with engine overheating, see “Engine
Overheating”
in the Index.
A 50/50 mixture of water and DEX-COOL’
coolant will:
J
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF 129 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

So, it isn‘t a good idea to “top oft“ your brake fluid.
Adding brake fluid won’t correct a leak. If YOU add fluid
when your linings are worn, then you’ll have loo much
fluid when you get new brake linings. You shouki add
(or remove) brake fluid, as necessary, only when work is
done
on the brake hydraulic system.
When your Srake fluid falls to a low level, your brake
warning light will come on. A chime will sound if you
try to drive with this warning light on. See “Brake
System Waning Eight” in the Index.
When you do need brake fluid, use only DOT-3
brAe fluid -- such as Delco Supreme II@ (GM
Part No. 12377967). Use new brake fluid from a
sealed container only.
Always clean the brake fluid reservoir cap and the
mea
around the cap before removing it. This will help
keep dirt from entering the reservoir.
~~ ~~
With the wrong kind of fluid in your brake
system,
your brakes may not work well, or they
may not even work at all. This could cause a
I
1 crash. Always use the proper brake fluid.

Some driving conditions or climates may cause a brake

applied. This does not mean something is wrong with
your brakes.

Every time
you apply the brakes, with or wiFhcut the
vehicle moving, your brakes adjust for wear.
Tie braking system a modem vehicle is complex.
Its many parts have to be of top quality and work weII
together if the vehicle is io lxwe reakly good braking.
Your vehicle \vas designed and tested with top-quality
GM brake puts. When you replace parts of your braking
system
-- for example, when your brake kings wear
down and you have to Rave new ones put irn -- be sure
you get new approved GM replacement parts. If YOQ
don't, your brakes may no ionger work properly. For
example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rex brzkes can change -- for the worse. The braking
performance
you've come to expect cm change in many
other ways if someone ~dts in the wrong replacement

Every new Buick has an ACIMCQ ~reedcm~ battery.
You never have to add water to one of these. Wen it's

Use a good quality pocket-type gage t~ check tire
pressure. You can’t tell. if your tires ae properly inflated
simply by
looking at them. Radial tires may lo&
properly inflated even when they’re underinnflated.
Be sure to put the
valve caps back on the valve stems.
They help prevent leaks by
keeping OU~ dirt md moisture.

The check tire pressure system can de& you to a
large change in the pressure of one tire. The system
won’t
alert you before you chive that a tire is low or
flat. You must begin driving before the system will
work properly.
The
TIRE PRESSURE LOW CHECK TIRES message
will appear on the Driver hf~~~~~ati~n Center (DK) if
pressure in one tire becomes at least 10 psi (69 Wa)
lower or higher than the other thee tires. The check tire
pressure system won’t alert you if more than one tire is
Bow or high, or if the system is not calibrated properly.
It also won’t tell YOU which tire is Bow or high.
E the anti-lock brake system waning light comes on,
the check tire pressure system may not be working
properly. See your deder for service. (Also,
see
“Anti-hck Brake System Wzming Light” in the Index.)

The following infomation relates to the system
developed by the United States
National Highway
Traffic Safety'Administration, which grades tires by
treadwear, traction and temperature pedommce.
(This applies only to vehicles sold in the 'United
States.) The grades are
molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type S~QW
tires, space-saver or temporary use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
IVhile the tires available on Generd Motors passenger
cars and light trucks may vary with respect to these
grades, they
must also confom to Federal safety
requirements
and additional General Motors Tire
Performance Criteria
(PC) standards.
