If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer. reduce the anlount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains
on steady. see “If
the Light Is On Steady” following.
If the light continues t.o flash, when it is safe to do so.
stop the \?el?ic&~. Find a safe place to park your vehiclc.
Turn the key off,
wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
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 s111-e to fully install
the cap. The diagnostic system can cleter~nine
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?
I1 so, be sure to fuel your vehicle with cpality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to
r11n as e,fficiently as designed. You may
notice this
as stalling after start-up, stalling when you put
the vehicle
into gear, mistlring, 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.
If none of the above steps have made the light. turn off.
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problcnls that may have developed.
Gate Ajar Light
GATE
AJAR
This light will come on
briefly when you are
starting
the engine. If' it
stays on, your liftgate is
ajar.
Try closing the liftgate
again. Never drive
with the
liftgate even partially open.
Fuel Gage
E-
When the ignition is on,
the fuel
gage tells you
about how much fuel you
11ave remaining.
0 It takes a little more or less file1 to fill up than the gage
inclicated. 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.
0 The gage moves a little when you turn a corner or
speed up.
Recreational Vehicle Towing (Except Four-wheel Drive With
Manual Shift Transfer Case) Loading Your Vehicle
Vehicles with
two-wheel drive or the optional electronic
shift transfer case require special modifications before
they can be towed
in this manner. Please contact your
dealer for the towing information that
is appropriate for
your particular vehicle.
Vehicles
with all-wheel drive (AWD) can not be towed
in this manner.
The Certification/Tire label is found on the driver’s door
edge, above the door latch. The label shows the size
of
your original tires and the inflation pressures needed to
obtain the gross weight capacity of your vehicle. This is
called the GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer.

Filling Your Tank
The fuel cap is behind
a hinged door on the
driver’s side
of
your vehicle.
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:
I
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
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
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 I I I
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.
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.
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.
