A CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a
50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
engine coolant at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
I A CAUTION:
~
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water
or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned. Use
a
50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine
and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the
fuel. In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the
air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for he1 that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and
also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other
fuel not
recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t
be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You
can also write us at the following address for
advice. Just tell
us where you’re going and give your
Vehicle Identification Number
(VIN).

Filling a Portable Fuel Container
I
1 A CAUTION: I
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged
if this
occurs. To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the ring
is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
Checking Things Under the Hood
The following sections tell you how to check fluids,
lubricants and important underhood parts.
A CAUTION:
I
An electric fan under the hood can start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
A CAUTION:
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that
will burn onto a hot engine.

Supercharged Engine (If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device designed to pump more air
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, increased 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 throttle cruising, the excess
air that the
supercharger is pumping is routed through
a bypass.
All of these controls, working together, provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
Engine Oil
CHECK OIL
LEVEL
If the CHECK OIL LEVEL
light on the instrument panel
comes
on, it means you need
to check your engine oil level
right away.
For more
information,
see “Check Oil
Level Light” in the Index. You
should check your engine oil level regularly;
this is
an added reminder.
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.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstic\
k
might not show
the actual level.
