It works only when the ignition is on. When the
indicator nears Empty (E) you still have a little fuel left.
There is a reserve of about 1.5 gallons (5.6 L) in the fuel
tank. You need to get more fuel right away.
Here are some concerns some owners have had about
the fuel gage. All these situations are normal and do not
indicate anything wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads Full (F).

It takes more (or less) gas to fill up than the gage
indicated. For example, the gage may have indicated
half full, but it took more (or less) than half of the
tank's capacity to fill it.

The gage moves a little when you turn a corner,
speed up or stop your vehicle.

When you turn the engine off, the gage doesn't go all
the way back to Empty (E).Low Fuel Light
A light near the Empty (E)
mark on the fuel gage
comes on when your vehicle
is low on fuel. You have
less than 3 gallons (11.7 L)
remaining in your fuel tank.

Filling a Portable Fuel Container
CAUTION:
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.

Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.

Don't smoke while pumping gasoline.
Checking Things Under the Hood
CAUTION:
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.
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.

Your vehicle has a 3800 Supercharged V6 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
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 ªCheck Oil Level Lightº 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.
The engine oil dipstick is a
round, yellow loop located
directly behind the
engine fan.
Turn off the engine and give
the oil several minutes to
drain back into the oil pan.
If you don't, the oil dipstick
might not show the
actual level.
