Fuel Gage
You have one of the fuel gages shown.
The fuel gage tells you about how much
fuel you have left, when the ignition is
on. When the indicator nears E (Empty),
you still have a little fuel left, but you
should get more
soon.
Here are three things that some owners
ask about. None of these show a
problem with your fuel gage:
At the gas station, with your ignition
on, the gas pump shuts off before the
gage reads
F (Full).
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
tanks capacity to fill the tank.
The gage moves a little when you turn
a corner
or speed up.
For your fuel tank capacity, see

Fuel
Use regular unleaded gasoline rated at
87 octane or higher. It should meet
specifications ASTM D4814 in the U.S.
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
U.S. 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 87.
If the octane is less than 87, you may
get a heavy knocking noise when you
drive. If
it’s bad enough, it can damage your
engine.
If you’re using fuel rated at 87 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t worry
if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal, and
you don’t have to buy a higher octane
fuel
to get rid of pinging. It’s the heavy,
constant knock that means you have a
problem.
Fuel Capacity:
16.5 U.S. Gallons (62 L) . Use unleaded
fuel only.
What about gasoline with blending
materials that contain oxygen, 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.
Fuel that is more than
5%
methanol is bad for your vehicl
Don’t use
it. It can corrode me
parts in your fuel system and a
damage plastic and rubber parts.
That damage wouldn’t be covered
under your warranty. And ev
5% or less, there must be
“cosolvents” and corrosion
