Fuel Gage
United States Canada
When the ignition is on, your fuel gage tells you about
how much fuel you have in your tank.When the gage reads in the yellow band, a warning
chime will sound and the CHECK GAGES warning
light will come on. You still have a little fuel left, but
you need to get more fuel right away.
On vehicles with the optional DIC, the CHECK GAGES
LOW FUEL message will be displayed when the fuel
gage reads in the yellow band. See ªDIC Warnings and
Messagesº in the Index for more information.
Here are some things that owner's ask about. None of
these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

It take a little more (or less) fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more (or less) than half the tank's capacity to
fill the 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
The following sections tell you how to check fluids,
lubricants and important underhood parts.
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.

Supercharged Engine (If Equipped)
Your vehicle may have a 3800 V6 (L67) 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
If the OIL LEVEL LOW
message appears on the DIC,
or the CHECK OIL LEVEL
light appears on the
instrument panel, it means
you need to check your
engine oil level right away.For more information, see ªCheck Oil Level Lightº or
ªDIC Warnings and Messagesº in the Index.
You should check your engine oil level regularly; this is
an added reminder.
Checking 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.
The engine oil dipstick is
located behind the engine
fans and in front of the
engine oil fill cap. The top
of the dipstick is a round
yellow loop.
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.
