If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently
put fuel into your vehicle'?
If so, reinstall the fuel cap. making sure to fully install
the cap. The diagnostic system can determine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water'?
If so. your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so. be sure to fuel your vehicle with quality fuel (see
"Fuel"
in the Index). Poor fuel quality will cause your
engine not
to run as efficiently as designed. You may
notice
this as stalling after start-up. stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling
on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light to turn on.
If you experience one or more of these conditions.
change the fuel brand
you use. It will require at least one
full tank of the proper fuel to turn the light off.
tr none of the above steps have made the light turn off,
have your ciealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problems
that may have developed.

briefly when you are
starting the engine. If

stays on. your liftgate is
ajar. Try closing
the liftgate
again. Never drive with the
liftgate even partially open.
Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much fuel
you
have remaining.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage:
At the gas stsiion, the ga rump shuts off before the
gage reads FULL (Fj.
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 or
speed up.
The gage doesn’t go back to EMPTY (E) when you
turn
off the ignition.

Downloaded from www.Manualslib.com manuals search engine Filling Your Tank
The fuel cap is behind
a hinged door
on the
driver’s side of
your vehicle.
A CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline
or refueling
your vehicle. Keep sparks, flames
and smoking
materials away from gasoline.
To take off the cap, turn
it slowly to the left
(counterclockwise). The
cap has a spring
in it; if
you let go of the cap
too soon, it will spring
back to the right.
A CAUTION:
If you get gasoline on yourself and then
something ignites
it, you could be badly burned.
Gasoline can spray
out on you if you open the
fuel filler cap too quickly. This spray can happen
if
your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any
“hiss” noise to stop. Then unscrew
the cap all the way.
6-5

Downloaded from www.Manualslib.com manuals search engine Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See "Cleaning the
Outside
of Your Vehicle" in the Index.
When you
put the 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"
in
the Index.
NOTICE:
If you need a new 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 your fuel tank and emissions system may be
damaged. See "Malfunction Indicator Lamp"
in
the Index.
Checking Things Under the Hood
1
To open the hood, first pull
the handle inside the vehicle
on the lower driver's side of
the instrument panel.
Then
go to the front of the vehicle and release the
secondary hood release.
6-6

Downloaded from www.Manualslib.com manuals search engine Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood to relieve pressure on the
hood prop.
Remove
the hood prop from the slot in the hood and
return the prop
to its retainer.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth,
then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
Then just pull the hood down firmly
to close. It will
latch when dropped from
10 to12 inches (25 to 30 cm)
without pressing on the hood.
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 oil dipstick
is a
yellow ring.
Turn off the engine and give
the oil a few minutes to
drain back into
the oil pan.
If
you don’t, the oil dipstick
might
not show the
actual level.
