2-75 Check Doors Light
This light is part of the
Systems Monitor. This
message means that either
the driver's door or one of
the passenger's doors is not
completely closed.
Fuel Gage
Cluster with Gages Cluster with Compass
and GagesWhen the ignition is on, your fuel gage tells you about
how much fuel you have left. When the gage reads in
the yellow band, a warning chime will sound and the
CHECK GAGES warning light will go on, if you have
this option. This warning means you are low on fuel.
You should get more fuel as soon as you can.
Here are some things that some owners 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 (F).

It takes 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.

The gage moves a little when you turn a corner,
speed up, or make a hard stop.

The gage doesn't go back to EMPTY (E) when you
turn off the ignition.

If you have the large span (220) gage, the needle
moves more for a given amount of fuel. This does
not indicate excessive fuel consumption, and
is normal.

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 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 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.
