Fuel Gage
Your fuel gage shows
approximately how
much fuel is in your
tank. It works only
when the ignition is
in
the RUN position.
PREMIUM UNLEADED
FUEL
ONLY
-_ Digital Gage
i-
If the fuel level is within approximately one gallon (3.8 liters) of being full,
the letter
F is shown.
If the fuel level is between one and two gallons (3.8 and 7.6 liters) from
being empty, the letter
E is shown. If the fuel supply gets down to
approximately one gallon (3.8 liters), the E will flash and the FUEL
LEVEL VERY LOW message will appear in the Driver Information
Center (DIC).
(On the analog fuel gage, the FUEL LEVEL VERY LOW
message will also appear.)
Here are a few concerns
some owners have had about the fuel gage. All of
these situations are ilormal and indicate that nothing is wrong with the
fuel gage.
At the gas station, the gas pump shuts off before the gage reads E
It takes more (or less) gas to fill the tank than the gage said. For
example, the gage read
8 GALLONS, but it took more (or less) than
the tank’s remaining capacity to
fill it.
The gage may change when you turn, stop or speed up.

FUEL
Use premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications
ASTM D4814 in the United States and CGSB 3.5-92
in Canada. These fuels should have the proper additives, so you should
not have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you get the right
kind
of gasoline (unleaded). You’ll see UNLEADED right on the pump.
And only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane
is at least 91. If the octane is less than 91, you
may get a heavy knocking noise when you drive. (In an emergency, you
may be able to use lower octane
-- as low as 87 -- if heavy knocking does
not occur.) If you’re using 91 or higher octane unleaded gas and you still
get heavy knocking, your engine needs service.
What about gasoline with blending materials that contain oxygen
(oxygenates), such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than 15%
MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
I NOTICE:
Fuel that is more than 5% methanol is bad for your vehicle.
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. And even at
5% or less, there must
be “cosolvents” and corrosion preventers in this fuel to help
avoid these problems.
