Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
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?
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount 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 to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
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
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.

The Certificationmire label in your vehicle will look
similar to this example. The
CertificatiodTire label is found on the rear edge of
the driver’s door. 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 tongue weight,
if pulling
a trailer.
The CertificationITire label also tells
you the maximum
weights for
the front and rear axles, called the Gross
Axle Weight Rating (GAWR). To find out the actual
loads on your front and rear axles,
you need to go to a
weigh station and weigh your vehicle. Your dealer can
help you with this. Be sure
to spread out your load
equally on both sides of the centerline.
Never exceed
the GVWR for your vehicle, or GAWR
for either the front or rear axle.
And,
if you do have a heavy load, you should spread it out.

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.
6-5

Downloaded from www.Manualslib.com manuals search engine 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.
While refueling, place the cap in the holder on the fuel
filler door.
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.
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.
6-6

Downloaded from www.Manualslib.com manuals search engine 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 Hoc4
m-
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You
or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.

Downloaded from www.Manualslib.com manuals search engine Inflation -- Tire Pressure
The CertificationRire label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your
tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than
1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right.
It’s not. If your tires
don’t have enough
air (underinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued) NOTICE: (Continued)
If your tires have too much air
(overinflation),
you can get the following:
0 Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards.
When
to Check
Check your tires once a month or more.
Don’t forget your compact spare tire.
It should be at
60 psi (420 kPa).
How to Check
use a
good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back
on the valve stems.
They help prevent leaks by keeping
out dirt and moisture.
