When the indicator nears empty, you still have a little
fuel left, but you should get more soon.
If your fuel is low, the warning message in the message
center will come on. See
Low Fuel Warning Message
on page
3-49.
Your fuel gage tells you about how much fuel you have
left when the ignition is on.
Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off before
the gage reads full.
0 It takes a little more (or less) fuel to fill up than the
gage reads. For example, the gage reads half full,
but it took more (or less) than half of the tank’s
capacity to
fill it.
0 The gage pointer may move while cornering,
0 The gage may not indicate empty when the ignition

Gasoline Specifications
Use of the recommended fuel is an important part of
the proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of
87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive.
If this
occurs, use a gasoline rated at
87 octane or higher
as soon as possible. Otherwise, you might damage
your engine.
A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using
87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service. It
is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system can
determine
if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See
Malfunction Indicator Lamp on
page 3-47.
The malfunction indicator lamp (SERVICE ENGINE
SOON or CHECK ENGINE light) will come on
if the
fuel cap is not properly installed.
Notice: If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not fit properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See “Malfunction Indicator Lamp”
in the
Index.
Filling a Po -able Fuel C ‘ainer
I-
I fil portablc uel 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.
